Simultaneous Deep Endometriosis Affecting Abdominal Wall and Vermiform Appendix / Endometriosis Simultánea de Pared Abdominal y Apéndice Vermicular

SUMMARY: Endometriosis, defined as the presence of endometrial glands and stroma outside the uterine cavity, is a chronic inflammatory condition that affects between 8 % and 44 % of women of reproductive age. Occasionally it presents as a sensitive mass in the abdominal wall, in relation to a surgical scar. On the other hand, in the most severe stage of endometriosis, intestinal involvement is common, and endometriotic disease of the appendix may be present even in appendices with macroscopically normal appearance. Simultaneous affectation of both locations is very rare. Nevertheless, treatment of choice is the excision of both lesions with safety margins. The aim of this manuscript was to report a case of simultaneous deep endometriosis affecting the total abdominal wall and vermiform appendix, resected in a single surgical procedure, which subsequently required abdominal wall repair with mesh plasty. Since desmoid tumors and endometriosis share similar clinical signs and unspecific imaging exams, both options should be considered in case of abdominal wall mass in female patients of childbearing age, especially if they have a history of uterine-related surgery.

La endometriosis se define como la presencia de glándulas endometriales y estroma fuera del útero. Es una afección crónica que afecta entre el 8 % y el 44 % de las mujeres en edad reproductiva. Ocasionalmente se presenta como una masa sensible en la pared abdominal, en relación con una cicatriz quirúrgica. Por otro lado, en su estadio más grave de la endometriosis, la afectación intestinal es común y puede afectar al apéndice, pudiendo estar presente incluso en apéndices de apariencia macroscópicamente normal. La afectación de ambas localizaciones simultáneamente es muy infrecuente. Sin embargo, el tratamiento de ambas lesiones es su exéresis quirúrgica con márgenes de seguridad. El objetivo de este manuscrito fue reportar un caso de endometriosis profunda simultánea que afectaba la pared abdominal total y el apéndice vermiforme, las que fueron resecadas en un solo tiempo quirúrgico, incluyendo posteriormente reparación de la pared abdominal con uso de malla. Dado que los tumores desmoides y la endometriosis comparten signos clínicos similares y exámenes de imágenes inespecíficos, se deben considerar ambas opciones en caso de masas en la pared abdominal de mujeres en edad fértil, especialmente si tienen antecedentes de cirugía relacionada con el útero.

Factors associated with deep infiltrating endometriosis, adenomyosis and ovarian endometrioma

INTRODUCTION@#To compare epidemiological features and clinical presentations of deep infiltrating endometriosis with endometrioma and adenomyosis, as well as to identify risk factors for the respective histologically confirmed conditions.@*METHOD@#Patients undergoing index surgery at the National University Hospital, Singapore for endometriosis or adenomyosis over a 7-year period-from 2015 to 2021-were identified from hospital databases using the Table of Surgical Procedures coding. Social and epidemiological features of cases with histologically confirmed diagnoses of endometrioma only, adenomyosis only, and deep infiltrating endometriosis were compared. Significant variables from univariate analysis were entered into 3 binary multivariate logistic regression models to obtain independent risk factors for: deep infiltrating endometriosis versus endometrioma only, deep infiltrating endometriosis versus adenomyosis only, and adenomyosis only versus endometrioma only.@*RESULTS@#A total of 258 patients were included with 59 ovarian endometrioma only, 47 adenomyosis only, and 152 deep infiltrating endometrioses. Compared to endometrioma only, deep infiltrating endometriosis was associated with higher rates of severe dysmenorrhoea (odds ratio [OR] 2.80, 95% confidence interval [CI] 1.02-7.70) and out-of-pocket private surgical care (OR 4.72, 95% CI 1.85-12.04). Compared to adenomyosis only, deep infiltrating endometriosis was associated with a higher fertility desire (OR 13.47, 95% CI 1.01-180.59) and a lower body mass index (OR 0.89, 95% CI 0.79-0.99). In contrast, heavy menstrual bleeding was the hallmark of adenomyosis, being less common in patients with endometriosis.@*CONCLUSION@#Deep infiltrating endometriosis is associated with severe dysmenorrhoea, pain related to urinary and gastrointestinal tracts, higher fertility desire and infertility rate. Patients with pain symptomatology and subfertility should be referred early to a tertiary centre with the capability to diagnose and manage deep infiltrating endometriosis.

Endometrioid adenocarcinoma of the rectovaginal septum: A case report / 中南大学学报(医学版)

Primary endometrioid adenocarcinoma of the rectovaginal septum is rare. Its pathogenesis is not clear and there is no standard treatment. One patient with endometrioid adenocarcinoma of the rectovaginal septum arising from deep infiltrative endometriosis was admitted to Qingdao Municipal Hospital. The patient presented with incessant menstruation and abdominal distension. She had bilateral ovarian endometriotic cystectomy 6 years ago. Imaging findings suggested a pelvic mass which might invade the rectovaginal septum. Pathological results of primary surgery confirmed endometrioid carcinoma of the pelvic mass arising from the rectovaginal septum. Then she had a comprehensive staged surgery. Postoperative chemotherapy was given 6 times. No recurrence or metastasis was found during the 2-year follow-up. The possibility of deep infiltrating endometriosis and its malignant transformation should be considered in the differential diagnosis of a new extragonadal pelvic lesion in a patient with a history of endometriosis, which would avoid misdiagnosis and missed diagnosis.

Study on the predictive significance of PLR, SII and RPR in ovarian endometriotic cyst / 中华妇产科杂志

Objective: To investigate the predictive value of platelet-to-lymphocyte ratio (PLR), red blood cell distribution width to platelet count ratio (RPR) and systemic immune inflammation index (SII) in the staging and postoperative recurrence of ovarian endometrial cysts. Methods: Retrospective analysis was made on the clinical data of patients who underwent laparoscopic surgery for ovarian cysts in the Affiliated Hospital of Qingdao University from January 2018 to January 2020. The patients with ovarian endometriosis cyst confirmed by pathology after surgery were the observation group (n=350), and the patients with other benign ovarian cyst were the control group (n=150). The preoperative platelet count, platelet distribution width, absolute number of neutrophils, lymphocyte absolute number, absolute number of monocytes, red blood cell distribution width, and serum cancer antigen 125 (CA125) of the patients in two groups were recorded, and PLR, neutrophil-to-lymphocyte ratio (NLR), RPR, SII, and systemic inflammation response index (SIRI) were calculated and analyzed. The general data of all patients and the follow-up data within 2 years after the operation of the observation group were statistically recorded to evaluate the diagnostic value of PLR, RPR and SII for ovarian endometrial cyst, and the predictive value of staging and recurrence within 2 years after the operation. Results: PLR, NLR, SII (median: 147.53, 1.86, and 488.70 respectively) and CA125 (median: 59.41 kU/L) in the observation group were significantly higher than those in the control group, while RPR (median: 0.16) was lower than that in the control group, with significant differences (all P<0.01). There was no significant difference in SIRI between the two groups (P>0.05). The PLR and SII (median: 122.73, 345.00) of the observation group at stage Ⅲ and Ⅳ were higher than those of patients at stage Ⅰ and Ⅱ, and the RPR was lower than that of patients with stage Ⅰ and Ⅱ, with significant differences (all P<0.001). The PLR, NLR, SII, SIRI (median: 179.63, 2.75, 762.96, and 1.06 respectively) and CA125 (median: 108.83 kU/L) in patients with recurrence were significantly higher than those in patients without recurrence 2 years after the operation, and the differences were statistically significant (all P<0.001). The area under curve (AUC) of CA125 in the diagnosis of ovarian endometriosis cyst was 0.951, the sensitivity was 85.7%, and the specificity was 93.0%, which were higher than those of PLR and SII; the AUC of PLR+SII+CA125 in the diagnosis of ovarian endometriosis cyst was 0.952. The AUC of RPR predicting the stage of ovarian endometriosis cyst was 0.713, higher than PLR and SII, lower than CA125; the AUC of RPR+SII+CA125 in predicting the stage of ovarian endometriotic cyst was 0.825, with sensitivity of 68.7% and specificity of 85.7%. The AUC predicted by SII for recurrence of ovarian endometriotic cyst within 2 years after the operation was 0.803, higher than NLR, PLR, SIRI and CA125; the AUC of PLR+SII+CA125, sensitivity, specificity was 0.813, 81.5% and 73.0%, higher than SII. Conclusion: PLR, RPR and SII are related to the staging of ovarian endometriotic cyst, and SII has a certain predictive value for the recurrence of ovarian endometriotic cyst after surgery.

Clinical analysis of 244 cases with abdominal wall endometriosis / 中华妇产科杂志

Objective: To investigate the clinical characteristics, diagnosis, treatment, outcomes and prognostic factors of abdominal wall endometriosis (AWE). Methods: A total of 265 AWE patients who underwent surgical treatment in The First Affiliated Hospital of Anhui Medical University from January 2010 to April 2023 were retrospectively selected, and 244 patients had complete follow-up data. According to different depth of lesions, the enrolled patients were divided into three types: type Ⅰ (subcutaneous fat layer, n=30), type Ⅱ (anterior sheath muscle layer, n=174) and type Ⅲ (peritoneum layer, n=40). The general clinical features, perioperative conditions, recurrent outcome and prognostic factors were analyzed in three types. Results: (1) Compared with type Ⅲ patients, the age of onset, parity and incidence of pelvic endometriosis were significantly decreased in type Ⅱ patients [(32.0±4.0) vs (30.0±4.6) years, 1.6±0.6 vs 1.4±0.5, 10.0% (4/40) vs 1.7% (3/174), respectively; all P<0.05], while the proportion of patients with transverse incision was significantly increased [37.5% (15/40) vs 67.3% (115/171); P<0.01]. The first symptoms of type Ⅰ and type Ⅱ were mainly palpable mass in the abdominal wall [73.3% (22/30), 63.2% (110/174), respectively], but the first symptom of type Ⅲ was pain in the abdominal wall [55.0% (22/40); all P<0.05]. (2) No matter the results of preoperative B-ultrasound or intraoperative exploration, the lesion diameters of type Ⅰ, type Ⅱ and type Ⅲ showed significant upward trends (all P<0.05). The proportions of lesion diameter≥3 cm in type Ⅱ and type Ⅲ [67.8% (118/174), 80.0% (32/40)] were significantly higher than that in type Ⅰ (all P<0.05). The median operation time and blood loss of type Ⅰ and Ⅱ were significantly lower than those of type Ⅲ (type Ⅰ vs type Ⅲ: 37.5 vs 50.0 minutes, 10 vs 20 ml, all P<0.05; type Ⅱ vs type Ⅲ: 35.0 vs 50.0 minutes, 10 vs 20 ml, all P<0.05). (3) The median follow-up time was 49 months, the overall symptom remission rate was 98.4% (240/244), and the recurrence rate was 7.0% (17/244). There were no significant differences in recurrence rate and recurrence free time among three types (all P>0.05). Multivariate regression analysis showed that the depth, number, diameter of lesions and postoperative adjuvant medication were not significant factors for postoperative recurrence (all P>0.05). Conclusions: The clinical manifestations of type Ⅲ are the most serious, including obvious abdominal pain symptoms, larger lesion diameter, prolonged operation time, increased intraoperative blood loss and increased incidence of pelvic endometriosis. Complete resection of lesions is an effective treatment for AWE, with high symptom remission rate and low recurrence rate. The depth, number, diameter of lesions and postoperative adjuvant medication are not risk factors for recurrence.

Efficacy of Chinese Herbal Medicines on Pregnancy Outcomes in Patients with Endometriosis in Long-Term Management: A Multicenter Retrospective Cohort Study / 中国结合医学杂志

OBJECTIVE@#To analyze the factors related to pregnancy of endometriosis and whether Chinese herbal medicines (CHMs) can improve pregnancy outcomes in patients with endometriosis in long-term management.@*METHODS@#This multicenter cohort study retrospectively analyzed the clinical data of endometriosis patients with fertility needs from January 2019 to November 2019. A total of 252 patients with endometriosis from 5 level-III Grade A hospitals in Beijing were included in this study. Univariate and multivariate logistic regression analysis were performed for the relevant factors. The propensity score matching (PSM) function of SPSS software was used to match the CHMs group with the non-CHMs group. The pregnancy rate and live birth rate were analyzed.@*RESULTS@#The results of univariate analysis showed that age, disease course, presence of infertility, presence of adenomyosis, time after surgery or use of gonadotropin-releasing hormone agonist (GnRH-a), use of CHMs and follow-up time were influencing factors of pregnancy in endometriosis patients (P<0.05). The results of multivariate analysis showed that age, presence of adenomyosis, time after surgery or use of GnRH-a, use of CHMs and follow-up time were independent factors affecting pregnancy in endometriosis patients, among which, age ⩾35 years old, presence of adenomyosis and follow-up time >6 months were independent risk factors (OR=0.445, 0.348, 0.140, respectively, P<0.05), time after surgery or use of GnRH-a ⩽6 months and use of CHMs were independent protective factors (OR=3.839, 3.842, respectively, P<0.05). After PSM, 99 pairs of two groups were matched successfully. The pregnancy rate of the CHMs group was higher than that of the non-CHMs group [55.56% (55/99) vs. 36.36% (36/99), P<0.05]. The live birth rate of the CHMs group was higher than that of the non-CHMs group [49.49% (49/99) vs. 35.35% (35/99), P<0.05].@*CONCLUSION@#CHMs can effectively improve clinical pregnancy rate and live birth rate of patients with endometriosis in the chronic disease management.

Dispareunia profunda 1 ano após cirurgia minimamente invasiva de endometriose / Deep dyspareunia 1 year after minimally invasive endometriosis surgery

A endometriose é uma doença crônica associada à dor pélvica e infertilidade, que afeta a vida das mulheres em diversos aspectos como as relações sociais, sexualidade e saúde mental. O tratamento cirúrgico pode auxiliar no tratamento de diferentes tipos de dores relacionadas à endometriose, mas as consequências do procedimento em mulheres que não apresentavam dor antes da cirurgia normalmente não são reportadas. Este estudo observacional multidisciplinar do tipo série de casos avaliou 195 casos consecutivos de mulheres sexualmente ativas que foram submetidas a cirurgia de endometriose para infertilidade ou dor persistente em uma instituição privada especializada em cirurgia minimamente invasiva. O objetivo do estudo foi avaliar as alterações na dispareunia profunda um ano após cirurgia minimamente invasiva para endometriose. De um total de 259 mulheres elegidas para o estudo, 195 atenderam aos critérios de inclusão/exclusão e completaram o acompanhamento clínico de 12 meses após a cirurgia. Usando uma escala verbal numérica (EVN) de 11 pontos (0-10), as mulheres foram agrupadas de acordo com a intensidade da dispareunia profunda relatada antes da cirurgia: AUSENTE (EVN = 0), LEVE (1 ≤ EVN ≤ 3), MODERADA (4 ≤ EVN ≤ 6), e INTENSA (EVN ≥ 7). Em uma análise inicial, houve melhora significativa após 1 ano e quase metade das mulheres com dispareunia profunda (NRS>0) tornou se livre deste sintoma (NRS=0). No grupo AUSENTE (N=87), 11 mulheres reportaram dispareunia profunda 6 meses após a cirurgia, mas apenas 1 persistiu com esse sintoma no seguimento de 1 ano, condição denominada Dispareunia Profunda De Novo. Nos grupos MODERADA (N=41) e INTENSA, a melhora da dispareunia profunda 12 meses após a cirurgia foi significativa (P<0,001). Com base nos resultados, o risco de uma mulher com dispareunia profunda intensa (EVN>7) ser beneficiada pela cirurgia com diminuição do escore ≥ 3 pontos é de 82,2% (IC95%: 72,4-92,0), enquanto o risco de uma mulher sem dispareunia profunda (EVN=0) permanecer sem este sintoma após a cirurgia é de 70,1% (IC95%: 60,3-79,2). Uma análise detalhada dos casos com desfechos desfavoráveis permitiu identificar que o desenvolvimento da dispareunia profunda nos primeiros 6 meses após a cirurgia pode estar relacionado à manipulação cirúrgica do septo retovaginal e vagina, o que não foi comum nos casos que desenvolveram dispareunia profunda 12 meses após a cirurgia.

Endometriosis is a chronic disease associated with pelvic pain and infertility that affects women's lives in various aspects such as social relationships, sexuality and mental health. Surgical treatment can help in treating different types of endometriosis-related pain, but the consequences of the procedure in women who did not experience pain before surgery are usually not. This multidisciplinary case series observational study assessed 195 consecutive cases of sexually active women who had undergone endometriosis surgery for infertility or persistent pain in a private medical facility specialized in minimally invasive surgery. The aim of the study was to evaluate changes in deep dyspareunia one year after minimally invasive endometriosis surgery. Of a total of 259 women selected for the study, 195 met the inclusion/exclusion criteria and completed clinical follow-up 12 months after surgery. Using a numeric rating scale (NRS) of 11 points (0-10), women were grouped according to the intensity of deep dyspareunia prior to surgery: ABSENT (NRS = 0), MILD (1 ≤ NRS ≤ 3), MODERATE (4 ≤ NRS ≤ 6), and SEVERE (NRS ≥ 7). In an initial analysis, there was a significant improvement after 1 year and almost half of women with deep dyspareunia (NRS >0) became free of this symptom (NRS = 0). In the ABSENT group (N=87), 11 women developed deep dyspareunia 6 months after surgery, but only 1 persisted with this symptom in the following 1 year, a condition called De Novo Deep Dyspareunia. In the MODERATE (N=41) and SEVERE groups, the improvement in deep dyspareunia 12 months after surgery was significant (P<0,001). A thorough analysis of the cases with a focus on individual variations allowed the detection of different response patterns over the first year after surgery. According to the findings, the risk of a woman with severe deep dyspareunia (EVN>7) benefiting from surgery with ≥ 3 point decrease in score is 82.2% (IC95%: 72.4-92,0), while the risk of a woman without deep dyspareunia (EVN=0) remaining without this symptom after surgery is 70.1% (IC 95%: 60,3- 79,2). A detailed examination of the cases with negative outcomes revealed that the development of deep dyspareunia in the first 6 months after surgery may be related to surgical manipulation of the rectovaginal septum and vagina, which was not seen in cases with deep dyspareunia 12 months after surgery.

Sexual Function of Patients with Deep Endometriosis after Surgical Treatment: A Systematic Review / Função sexual em pacientes com endometriose profunda após o tratamento cirúrgico: Revisão sistemática

Abstract Objective To review the current state of knowledge on the impact of the surgical treatment on the sexual function and dyspareunia of deep endometriosis patients. Data Source A systematic review was conducted in accordance with the Meta-Analysis of Observational Studies in Epidemiology (MOOSE) guidelines. We conducted systematic searches in the PubMed, EMBASE, LILACS, and Web of Science databases from inception until December 2022. The eligibility criteria were studies including: preoperative and postoperative comparative analyses; patients with a diagnosis of deep endometriosis; and questionnaires to measure sexual quality of life. Study Selection Two reviewers screened and reviewed 1,100 full-text articles to analyze sexual function after the surgical treatment for deep endometriosis. The risk of bias was assessed using the Newcastle-Ottawa scale for observational studies and the Cochrane Collaboration's tool for randomized controlled trials. The present study was registered at the International Prospective Register of Systematic Reviews (PROSPERO; registration CRD42021289742). Data Collection General variables about the studies, the surgical technique, complementary treatments, and questionnaires were inserted in an Microsoft Excel 2010 (Microsoft Corp., Redmond, WA, United States) spreadsheet. Synthesis of Data We included 20 studies in which the videolaparoscopy technique was used for the excision of deep infiltrating endometriosis. A meta-analysis could not be performed due to the substantial heterogeneity among the studies. Classes III and IV of the revised American Fertility Society classification were predominant and multiple surgical techniques for the treatment of endometriosis were performed. Standardized and validated questionnaires were applied to evaluate sexual function. Conclusion Laparoscopic surgery is a complex procedure that involves multiple organs, and it has been proved to be effective in improving sexual function and dyspareunia in women with deep infiltrating endometriosis.

Coleta de dados Variáveis gerais sobre os estudos, a técnica cirúrgica, os tratamentos complementares e os questionários foram inseridas em uma planilha do Microsoft Excel 2010 (Microsoft Corp., Redmond, WA, Estados Unidos). Síntese dos dados Foram incluídos 20 estudos em que se usou a técnica de videolaparoscopia para a excisão da endometriose profunda. Uma meta-análise não pôde ser realizada devido à heterogeneidade substancial entre os estudos incluídos. As classes III e IV da escala revisada da American Fertility Society foram predominantes, e múltiplas técnicas cirúrgicas foram usadas para o tratamento da endometriose. Questionários padronizados e validados foram aplicados para avaliar a função sexual. Conclusão A cirurgia laparoscópica é um procedimento complexo que envolve múltiplos órgãos, e provou ser eficaz na melhora da função sexual e da dispareunia em mulheres com endometriose profunda.

Postoperative Complications and Stoma Rates After Laparoscopic Resection of Deep Infiltrating Endometriosis with Bowel Involvement / Complicações pós-operatórias e taxas de estomia após ressecção laparoscópica de endometriose infiltrativa profunda com envolvimento intestinal

Abstract Objective The purpose was to assess the rates of postoperative complications and the need of temporary stoma of laparoscopic surgical treatment for bowel endometriosis in a referral center. Methods The surgical indication, type of operation, operative time, length of hospital stay, need for a temporary stoma, rate of conversion to open surgery, postoperative complications were evaluated. Results One-hundred and fifty patients were included. The average duration of surgery was significantly longer for segmental resection (151 minutes) than for disc excision (111.5 minutes, p < 0.001) and shaving (96.8 minutes, p < 0.001). Patients with segmental resection had longer postoperative lengths of hospital stay (1.87 days) compared with patients with disc excision (1.43 days, p < 0.001) and shaving (1.03 days, p < 0.001). A temporary stoma was performed in 2.7% of patients. Grade II and III postoperative complications occurred in 6.7% and 4.7% patients, respectively. Conclusion Laparoscopic intestinal resection has an acceptable postoperative complication rate and a low need for a temporary stoma.

Resumo Objetivo O objetivo foi avaliar as taxas de complicações pós-operatórias e a necessidade de estomia temporária do tratamento cirúrgico laparoscópico para endometriose intestinal em um centro de referência. Métodos Foram avaliados a indicação cirúrgica, tipo de operação, tempo operatório, tempo de internação, necessidade de estomia temporária, taxa de conversão para cirurgia aberta, complicações pós-operatórias. Resultados Cento e cinquenta pacientes foram incluídos. A duração média da cirurgia foi significativamente maior para a ressecção segmentar (151 minutos) do que para a excisão do disco (111,5 minutos, p < 0,001) e shaving (96,8 minutos, p < 0,001). Pacientes com ressecção segmentar tiveram maior tempo de internação pós-operatória (1,87 dias) em comparação com pacientes com excisão de disco (1,43 dias, p < 0,001) e shaving (1,03 dias, p < 0,001). Um estoma temporário foi realizado em 2,7% dos pacientes. Complicações pós-operatórias de grau II e III ocorreram em 6,7% e 4,7% dos pacientes, respectivamente. Conclusão A ressecção intestinal laparoscópica apresenta taxa aceitável de complicações pós-operatórias e baixa necessidade de estomia temporária.

Endometriosis de la pared abdominal en relación con cicatriz de operación cesárea: serie de casos / Abdominal wall endometriosis in relation to cesarean section scar: number of cases

RESUMEN: La endometriosis (E), se define como presencia de glándulas endometriales y estroma fuera del útero. Ocasionalmente se presenta como masa sensible en la pared abdominal (PA), en relación con una cicatriz quirúrgica (EPA). Aunque el tratamiento es quirúrgico, existe poca información respecto de la morbilidad postoperatoria (MPO) y la recurrencia de la EPA. El objetivo de este estudio fue determinar MPO y recurrencia en pacientes resecadas quirúrgicamente por EPA. Serie de casos de pacientes con EPA, sometidos a cirugía de forma consecutiva, en Clínica RedSalud Mayor, entre 2011 y 2021. Las variables resultados MPO y recurrencia. Otras variables de interés fueron: tiempo quirúrgico, estancia hospitalaria y mortalidad. Las pacientes fueron seguidas de forma clínica. Se utilizó estadística descriptiva, con medidas de tendencia central y dispersión. Se intervinieron 14 pacientes, con una mediana de edad de 33 años. La medianas del tiempo quirúrgico y estancia hospitalaria; fueron 55 min y 2,5 días respectivamente. La MPO fue 14,2 % (2 casos). Con una mediana de seguimiento de 31 meses, no se verificó recurrencia. Aunque la EPA es poco común, estas lesiones deben sospecharse en mujeres en edad reproductiva con masa palpable en relación con una cicatriz de cirugía ginecológica u obstétrica. Los resultados obtenidos, en términos de MPO y recurrencia, fueron similares a series internacionales.

SUMMARY: Endometriosis (E) is defined as the presence of endometrial glands and endometrial stroma outside the uterus. Occasionally it presents as a sensitive mass in the abdominal wall (AW), in relation to a surgical scar (AWE). Although the treatment is surgical, there is scarce information regarding postoperative morbidity (POM) and recurrence of AWE. The aim of this study was to determine POM and recurrence in patients surgically resected by AWE. Case series of patients with AWE, consecutively submitted to surgery, at RedSalud Mayor Clinic, between 2011 and 2021. Outcome variables were POM and recurrence. Other variables of interest were surgical time, hospital stay and mortality. Patients were followed-up clinically. Descriptive statistics were used, applying central tendency and dispersion measures. 14 patients were intervened, with a median age of 33 years. Median of surgical time and hospital stay were 55 min and 2,5 days respectively. POM was 14.2 % (2 cases). With a median follow-up of 31 months no recurrence was verified. Although AWE is uncommon, these lesions should be suspected in women in fertile age with a palpable mass associated with a scar from gynecologic or obstetric surgery. The results obtained, in terms of POM and recurrence, were like international series.

Effect of Surgical Treatment for Deep Infiltrating Endometriosis on Pelvic Floor Disorders: A Systematic Review with Meta-analysis / Efeito do tratamento cirúrgico para endometriose infiltrante profunda nas disfunções do assoalho pélvico: Uma revisão sistemática com metanálise

Abstract Objectives To evaluate the impact of surgical treatment of deep infiltrative endometriosis (DIE) on pelvic floor dysfunction (urinary incontinence [UI], pelvic organ prolapse [POP], fecal incontinence [FI)] or constipation, and sexual function [dyspareunia]). Data Source The present systematic review was performed in the PubMed database. For the selection of studies, articles should be published by January 5, 2021, without language restriction. Study Selection Six randomized controlled studies that evaluated surgical treatment for DIE and the comparison of different surgical techniques were included. Data Collection The studies were selected independently by title and abstract by two authors. Disagreements were resolved by a third author. All included studies were also evaluated according to the Cochrane risk of bias tool and the quality of the evidence was analyzed using the GRADE criteria. Subgroup analysis by different treatments and follow-up periods was also performed. Results Six studies were included in the quantitative analysis. The risk of bias between studies showed an uncertain risk of bias for most studies, with concealment of allocation being the least reported category. The quality of the evidence was considered low. High heterogeneity was found between the studies. No study has evaluated UI or POP comparatively before and after surgery. Conclusion Dyspareunia and FI have improved after the surgical procedure, but it was not possible to demonstratewhich surgical technique was related to these outcomes as there was surgical heterogeneity. This diversity was found across data, with the recommendation of future prospective studies addressing pelvic floor disorders withDIE.

Resumo Objetivos Avaliar o impacto do tratamento cirúrgico para endometriose infiltrante profunda (EIP) nas disfunções do assoalho pélvico (incontinência urinária [IU], prolapso de órgãos pélvicos [POP], incontinência fecal [IF] ou constipação e função sexual [dispareunia]). Fonte de Dados A presente revisão sistemática foi realizada na base de dados PubMed. Para a seleção dos estudos, os artigos deveriam ser publicados até 5 de janeiro de 2021, sem restrição de idioma. Seleção dos Estudos Foram incluídos seis estudos randomizados e controlados que avaliaram o tratamento cirúrgico para EIP e a comparação de diferentes técnicas cirúrgicas. Coleta de Dados Os estudos foram selecionados de forma independente por título e resumo por dois autores. As discordâncias foram avaliadas por umterceiro autor. Todos os estudos incluídos foram avaliados de acordo coma ferramenta Cochrane de risco de viés e a qualidade de evidência foi analisada usando os critérios GRADE. A análise de subgrupo por diferentes tratamentos e períodos de acompanhamento também foi realizada. Resultados Seis estudos foram incluídos na análise quantitativa. O risco de viés mostrou um risco incerto de viés para a maioria dos estudos, sendo a ocultação da alocação a categoria menos relatada. A qualidade de evidência foi considerada baixa. Alta heterogeneidade foi encontrada entre os estudos. Nenhum estudo avaliou a IU ou o POP comparativamente antes e após a cirurgia. Conclusão A dispareunia e a IF melhoraram após o procedimento cirúrgico, mas não foi possível demonstrar qual técnica cirúrgica esteve relacionada a estes desfechos, pois houve heterogeneidade cirúrgica. Esta diversidade foi encontrada nos dados, com a recomendação de estudos prospectivos futuros abordando distúrbios do assoalho pélvico com EIP.

Endometriosis umbilical primaria: reporte de dos casos / Primary umbilical endometriosis: two case reports

INTRODUCCIÓN: La endometriosis es una patología benigna, dependiente de estrógenos, en la que el tejido que normalmente crece dentro del útero aparece fuera de este. Su localización habitual es en la pelvis, pero en ocasiones puede aparecer en otras áreas, como es el caso de la endometriosis umbilical. OBJETIVO: Familiarizar al ginecólogo con esta patología y entregar una serie de herramientas para diagnosticar, tratar y seguir a las pacientes que la presentan. CASOS CLÍNICOS: Se presentan dos casos clínicos de endometriosis umbilical primaria diagnosticados en el Hospital La Paz, en Madrid (España), entre los años 2018 y 2019. Las pacientes, de 30 y 34 años, consultaron por dolor o sangrado umbilical durante la menstruación. Ninguna tenía antecedentes de patología ginecológica ni cirugía abdominal previa. Tras una exhaustiva exploración física y una ecografía de alta resolución, se decidió extirpar la lesión con la colaboración del servicio de cirugía plástica. En ambos casos, el estudio anatomopatológico confirmó que se trataba de tejido endometriósico. Las dos pacientes presentaron una buena evolución posquirúrgica, sin recidivas hasta la fecha. CONCLUSIONES: La endometriosis umbilical primaria es una patología infrecuente, pero es necesario incluirla en el diagnóstico diferencial de una mujer con un nódulo umbilical. Siempre deben realizarse una exploración física exhaustiva y una ecografía ginecológica, para descartar posibles patologías concomitantes. El tratamiento de elección es la extirpación quirúrgica de la lesión y el diagnóstico final se establece con el estudio anatomopatológico.

INTRODUCTION: Endometriosis is an estrogen-dependent benign pathology in which endometrial tissue develops outside the uterus. Its most frequent location is the pelvis, although it can appear in other areas such as the umbilicum. OBJECTIVE: To familiarize the gynecologist with this pathology and provide a series of tools to diagnose, treat and provide continued care to these patients. CASE REPORTS: Retrospective study of two clinical cases of primary umbilical endometriosis diagnosed at La Paz University Hospital, in Madrid (Spain), between 2018 and 2019. Both patients (30 and 34 years old respectively) presented with pain and/or bleeding around the umbilical area during menstruation. Neither of them had any previous gynecologic conditions or abdominal surgeries. After exhaustive physical examination and a high-resolution ultrasound, lesions were surgically removed in collaboration with the plastic surgery department. In both cases, histology confirmed the presence of endometrial tissue. Both patients made a full recovery after surgery and havent had a recurrence of said lesions. CONCLUSIONS: Primary umbilical endometriosis is an infrequent disease. However, it must be included in the differential diagnosis of umbilical nodes in women. Exhaustive physical examination and gynecologic ultrasound should always be performed to rule out any other pathologies. Surgical removal of the nodes is the preferred treatment, and the final diagnosis is reached through histology.

Exclusión renal por endometriosis profunda ureteral: a propósito de un caso / Renal exclusion due to deep infiltrating ureteral endometriosis: a case report

INTRODUCCIÓN: La endometriosis ureteral es una afección rara que afecta al 0.01-1,7% de las mujeres con endometriosis. Hasta un 30% cursa de forma asintomática y un 11,5-14,7% pueden evolucionar con falla renal. La falta de diagnóstico de la enfermedad puede terminar en una uropatía obstructiva y falla renal irreversible. Se presenta el caso de una paciente con afectación grave de la función renal secundaria a endometriosis profunda con compromiso ureteral. CASO CLÍNICO: Mujer de 35 años con endometriosis que consultó por exacerbación de los síntomas. En su estudio destaca, en la resonancia magnética, el hallazgo de endometriosis pélvica profunda y compromiso endometriósico intrínseco del uréter distal derecho, provocando una acentuada hidroureteronefrosis. El cintigrama renal demuestra acentuado compromiso de la función renal derecha, con una función relativa del 7%. Se realizaron nefrectomía total derecha y resección de enfermedad pélvica profunda laparoscópica, sin incidentes. CONCLUSIONES: La endometriosis ureteral representa un desafío diagnóstico y terapéutico. El manejo multidisciplinario entre radiólogos, ginecólogos y urólogos, mediante el diseño de una estrategia quirúrgica individualizada, es imprescindible para definir el tratamiento óptimo de estas pacientes.

INTRODUCTION: Ureteral endometriosis is a rare entity that affects 0.01-1,7% of women with endometriosis. Up to 30% of the patients are asymptomatic and 11.5-14.7% will develop renal failure. Misdiagnosis can lead to obstructive uropathy and permanent renal failure. We present the case of a patient with severe compromise of renal function secondary to deep infiltrating endometriosis with ureteral involvement. CASE REPORT: A 35-year-old woman with endometriosis presented with exacerbation of symptoms. Magnetic resonance showed deep pelvic endometriosis and intrinsic endometriotic involvement of the right distal ureter, causing a marked hydroureteronephrosis. Renal scintigram showed a severe compromise of the right renal function, with a relative function of 7%. Through laparoscopy a total right nephrectomy and resection of deep infiltrating endometriosis was performed. The patient had a satisfactory recovery in the postoperative period. CONCLUSIONS: Ureteral endometriosis presents a diagnostic and therapeutical challenge. Joint multidisciplinary management between radiologists, gynecologists and urologists through the design of an individualized surgical strategy is essential to define the optimal treatment for these patients.

Psychological Problems Experienced by Patients with Bowel Endometriosis Awaiting Surgery / Problemas psicológicos vivenciados por pacientes com endometriose intestinal aguardando cirurgia

Abstract Objective To assess the most common psychological disturbances in women with deep endometriosis and bowel involvement who are waiting surgical treatment and to evaluate what forms of coping are used to solve the problem. Methods This was a cross-sectional observational study of 40 women diagnosed with deep endometriosis and intestinal symptoms. They completed two questionnaires: one for anxiety and depression (Hospital Anxiety and Depression Scale [ HADS]) and the Scale of Mode of Confronting Problems (EMEP, in the Portuguese acronym). Results We found that 77.1% of the patients had anxiety and depression, with anxiety being the most prevalent (87.5% of the patients); 90% of the patients used problem focused and religious introspection as their main modes of confronting problems. Conclusion In the use of the HADS questionary, two psychological aspects were the most present in women with deep endometriosis awaiting surgical treatment: anxiety and depression. The most used forms of coping to solve the problem were problem coping and religious practices.

Resección intestinal por endometriosis severa, diagnóstico y tratamiento luego de la introducción de la Unidad de Endometriosis: revisión de 18 años en el Hospital Clínico de la Universidad de Chile / Bowel resection for severe endometriosis, diagnosis and treatment after the introduction of Endometriosis Unit: 18 years review, Clinical Hospital of the University of Chile

INTRODUCCIÓN: La endometriosis intestinal afecta en gran medida la calidad de vida de una mujer joven y habitualmente requiere un tratamiento quirúrgico con resección intestinal. Esta cirugía es técnicamente compleja por las adherencias firmes del intestino a la vagina, el útero y los ovarios. OBJETIVO: Describir y analizar los resultados quirúrgicos e histopatológicos de las resecciones intestinales por endometriosis grave durante los últimos 18 años en el Hospital Clínico de la Universidad de Chile, en relación con la introducción de la unidad multidisciplinaria de endometriosis, a partir del año 2011, y las experiencias publicadas en la literatura chilena y extranjera. MÉTODO: Trabajo retrospectivo realizado en un hospital terciario desde el año 2001 hasta el año 2019. Las pacientes se asignaron a dos grupos según el período de cirugía: grupo 2001-2010 y grupo 2011-2019, luego de la introducción de la unidad de endometriosis. Se recopilaron todas las pacientes a las que se realizó una resección intestinal (discoidal o segmentaria) por endometriosis, por laparotomía o laparoscopía. Los datos distribuidos normalmente se presentan como promedio ± DE y los datos no paramétricos como mediana (rango). Las comparaciones demográficas de variables continuas se hicieron con la prueba t de Student y las de las variables categóricas con las pruebas de ji al cuadrado o de Fisher. La significación estadística se estableció en p < 0,05. RESULTADOS: Se recopilaron 52 casos. El 94,2% de las cirugías fueron electivas. El 5,8% fueron de urgencia por obstrucción intestinal (todas entre 2001 y 2010). Un 75% de las cirugías fueron laparoscópicas. Se realizó resección segmentaria en el 67,3%, resección discoidal simple en el 28,8%, resección discoidal doble en el 1,9% y resección segmentaria y una discoidal en el 1,9%. La histopatología demostró compromiso de la lesión hasta la mucosa intestinal en un 7,7%. Hubo franca disminución del dolor en el seguimiento de las pacientes. El 24% de las pacientes con deseo de embarazo y endometriosis intestinal lograron un parto de término mediante fecundación in vitro o espontáneamente. Hubo cuatro complicaciones posoperatorias, tres de ellas de categoría II según la clasificación de Clavien-Dindo y una de categoría IV A con reintervención a las 72 horas. Al comparar ambos periodos, en 2001-2010 los exámenes diagnósticos utilizados fueron ecografía transvaginal (0%), enema baritado (60%), tomografía computarizada de abdomen y pelvis (45%) y resonancia magnética pelviana (20%), mientras que en 2011-2019 fueron ecografía transvaginal (100%), enema baritado (3%), tomografía computarizada (3%) y resonancia magnética pelviana (66%). En 2001-2010, las lesiones fueron más más infiltrativas (mayor compromiso mucoso y submucoso) (75 vs. 16% de las resecciones intestinales; p < 0,05), estenóticas (cirugías de urgencia por obstrucción), con mayor porcentaje de resecciones segmentarias (100 vs. 46,9%; p < 0,05) y más días de hospitalización (5,8 ± 2,3 vs. 4,1 ± 0,9 días) que en 2011-2019. CONCLUSIONES: A nuestro entender, esta es la serie más grande publicada en Chile de resecciones intestinales por endometriosis. Estos hallazgos demuestran cómo la introducción de la unidad multidisciplinaria de endometriosis permite un diagnóstico precoz y un tratamiento quirúrgico eficaz y oportuno, tal como se decribe en la literatura.

INTRODUCTION: Bowel endometriosis severely affects a young woman's quality of life and often requires surgical treatment with bowel resection. This surgery is technically complex due to the tight adhesions of the intestine to the vagina, uterus, and ovaries. The objective of this work is to describe and analyze the surgical and histopathological results of intestinal resections for severe endometriosis during the last 18 years at the Clinical Hospital University of Chile, in relation to the implementation of the multidisciplinary endometriosis unit, based on the year 2011 and the experiences published in Chilean and foreign literature. METHOD: Retrospective work carried out in a tertiary hospital from 2001 to 2019. The patients were assigned to two groups according to the surgery period: group 2001-2010 and group 2011-2019, after endometriosis unit formation. All patients who underwent bowel resection (discoidal or segmental) for endometriosis by laparotomy or laparoscopy were collected. Normally distributed data are presented as mean ± SD and nonparametric data as median (range). Demographic comparisons of continuous variables are compared using Student's t test and categorical variables using chi squared or Fisher's test. Statistical significance was established at p < 0.05. RESULTS: 52 cases were collected. 94.2% of the surgeries were elective. 5.8% were urgent due to intestinal obstruction (all between 2001 and 2010). 75% of the surgeries were laparoscopic. Segmental resection 67.3%, simple discoidal resection 28.8%, double discoidal resection 1.9% and segmental resection and a discoidal resection 1.9%. Histopathology showed involvement of the lesion up to the intestinal mucosa in 7.7%. A marked decrease in pain in the follow-up of the patients. 24% of the patients with a desire for pregnancy and intestinal endometriosis achieved a full-term delivery by IVF or spontaneously. There were four postoperative complications, three of them category II according to the Clavien-Dindo classification, and one category IV A complication with reoperation at 72 h. When comparing both periods, between 2001-2010 the diagnostic tests used were: transvaginal ultrasound (ECO TV) (0%), barium enema (BE) (60%), abdomen pelvis CT (45%) and pelvic resonance (MRI) (20%). Between 2011 and 2019 ECO TV (100%), EB (3%), TAC (3%) RM (66%). In the period 2001 to 2010, the lesions were more infiltrative (greater mucosal and submucosal involvement) (75% vs 16% of intestinal resections (P <0.05)), stenotic (urgent surgery for obstruction), with a higher percentage of resections segmental (100% vs 46.9% (P <0.05) and more days of hospitalization (5.8 ± 2.3 SD vs 4.1 ± 0.9 SD) than in the period from 2011 to 2019. CONCLUSIONS: To our knowledge, this is the largest series published in Chile of intestinal resections for endometriosis. These findings demonstrate how the introduction of the multidisciplinary endometriosis unit allows early diagnosis and effective and timely surgical treatment as described in the literature.

Resonancia magnética en el estudio de dos pacientes con dolor pélvico crónico asociado a endometriosis de infiltración profunda / Magnetic resonance imaging in the study of two patients with chronic pelvic pain associated to infiltrating endometriosis deep

INTRODUCCIÓN: La endometriosis de infiltración profunda (EIP) es una enfermedad crónica de difícil diagnóstico, que frecuentemente es confundida con otras patologías pelvianas. OBJETIVO: Presentar dos casos de endometriosis de infiltración profunda, donde la resonancia magnética (RM) de pelvis, fue importante para el diagnóstico y planificación del tratamiento quirúrgico. CASO CLÍNICO: Se describe el caso de dos pacientes. La primera de 24 años afectada por un nódulo de EIP retrocervical con extensión intestinal sintomática y la segunda, una paciente de 37 años con una recidiva sintomática de EIP en la cúpula vaginal después de una histerectomía total. RESULTADOS: La RM de pelvis describe en ambos casos la extensión de las lesiones endometriósicas y presenta una excelente correlación con los hallazgos intra operatorios en la laparoscopía quirúrgica. CONCLUSIONES: La RM de pelvis es un excelente recurso en el estudio diagnóstico de las pacientes con dolor pélvico crónico, tanto en el caso de EIP retrocervical con extensión intestinal y también en la recidiva de EIP en la cúpula vaginal después de una histerectomía total

INTRODUCTION: Deep infiltration endometriosis (DIE) is a chronic disease of difficult diagnosis, which is frequently confused with other pelvic pathologies. OBJETIVE: To present two cases of deep infiltrating endometriosis, where the pelvic magnetic resonance imaging (MRI) was important in the diagnosis and surgical treatment planning. CLINICAL CASES: Two cases, one 24 years-old patient suffering from retrocervical DIE nodule with symptomatic bowel involvement, and a 37 years-old patient, with a symptomatic DIE at the vaginal cuff after total hysterectomy. RESULTS: Pelvic MRI describes in both cases the extension of the endometriotic lesions and presents an excellent correlation with the intra operatory findings during surgical laparoscopy. CONCLUSIONS: Pelvic MRI is an excellent diagnostic tool for patients with pelvic pain, in case of retrocervical DIE with bowel involvement, and also in recurrence of DIE at the vaginal cuff after total hysterectomy

Evaluación de fuerza de concordancia de hallazgos de endometriosis en RM y laparoscopía: análisis de una serie de casos / Assessment concordance of endometriosis findings on MRI and laparoscopy: analysis of a series of cases

OBJETIVO: Evaluar concordancia de sitios de hallazgos de endometriosis profunda encontrados por RM y laparoscopia. MATERIALES Y MÉTODOS: Estudio retrospectivo, no experimental, concordancia intertécnica. Se recolectaron datos en nuestra institución de todos los informes de RM de pelvis que incluyeran la palabra "endometriosis", entre mayo de 2015 y abril de 2018 (36 meses), identificando 339 registros. Se establecieron criterios de inclusión. De los 339 registros, 62 pacientes fueron excluidas por cirugía antes de la RM. Otras 243 pacientes fueron excluidas porque no presentaban registro de protocolo quirúrgico posterior a la RM. 34 pacientes cumplieron los criterios de inclusión del estudio, lo que equivale al 10% de las RM estudiadas. Se revisaron las ubicaciones de los implantes endometriósicos informados en RM y se correlacionaron con los hallazgos encontrados en la cirugía. Se confecciono tabla para identificar la presencia/ausencia de implantes en las ubicaciones descritas en la literatura. Análisis estadístico mediante software Stata, aplicando kappa ponderada con intervalo de confianza de 95%. RESULTADOS: El promedio de edad de las pacientes llevadas a cirugía fue de 38 años. Los lugares con correlación moderada-importante (0.41-0.80) correspondieron a útero, recto-sigmoides, ovario, vagina y fondos de saco. CONCLUSIÓN: La RM de Pelvis es fundamental en la evaluación de pacientes con endometriosis en las que se plantea un manejo quirúrgico, con el objetivo de caracterizar la ubicación, forma y número de lesiones, y así lograr un satisfactorio tratamiento laparoscópico.

OBJECTIVE: To assess inter-observer reliability of sites of deep endometriosis findings found by MRI and laparoscopy. MATERIALS AND METHODS: Retrospective, non-experimental study, inter-observer reliability. Data were collected at our institution from all pelvic MRI reports that included the word "endometriosis", between May 2015 and April 2018 (36 months), identifying 339 records. The following were established as inclusion criteria. Of the 339 records, 62 patients were excluded for surgery prior to MRI. Another 243 patients were excluded because they had no record of the surgical protocol after the MRI. 34 patients met the study inclusion criteria, equivalent to 10% of the MRIs studied. The locations of the endometrial implants reported on MRI were reviewed and correlated with the findings found in the surgery. A table was prepared to identify the presence / absence of implants in the locations described in the literature. Statistical analysis using Stata software, applying weighted kappa with a 95% confidence interval. RESULTS: The average age of the patients undergoing surgery was 38 years. The places with a moderate-important correlation (0.41-0.80) corresponded to the uterus, recto-sigmoid, ovary, vagina, and recto-uterine pouch. CONCLUSION: Pelvic MRI is essential in the evaluation of patients with endometriosis in whom surgical management is proposed, in order to characterize the location, shape and number of lesions, and thus achieve satisfactory laparoscopic treatment.

Endometriosis con infiltración aislada del nervio ciático, una forma de presentación atípica: reporte de un caso clínico / Isolated infiltrative endometriosis of the sciatic nerve, an atypical presentation: clinical case report

INTRODUCCIÓN: La endometriosis afecta hasta un 10-15% de las mujeres jóvenes. Se define como tejido endometrial funcional fuera de la cavidad uterina y su presentación clásica es la dismenorrea. La variedad profunda afecta a un 1-2% y las localizaciones más frecuentes son el peritoneo pélvico, ovarios, ligamentos útero-sacros y septum recto-vaginal; sin embargo, puede presentarse de forma muy infrecuente como implantes aislados localizados en relación al nervio ciático. El diagnóstico habitualmente es complejo y tardío, dado que los síntomas son inespecíficos y el examen físico puede ser indistinguible de otras etiologías. El estudio imagenológico de elección para la endometriosis profunda es la resonancia magnética (RM) de pelvis ya que una adecuada localización pre-quirúrgica de las lesiones es fundamental. CASO CLÍNICO: Paciente de sexo femenino de 46 años, con tres años de dolor pélvico, dismenorrea y dispareunia. El síntoma cardinal fue dolor ciático progresivo, con déficit motor y alteraciones sensitivas, los cuales se exacerbaban durante la menstruación y no presentaban respuesta al tratamiento farmacológico. En la RM se identifica nódulo sólido sospechoso de endometriosis en relación al nervio ciático derecho. El caso es evaluado por un comité multidisciplinario y se realiza cirugía laparoscópica. El diagnóstico de sospecha es confirmado histológicamente. La paciente presenta buena recuperación post-quirúrgica y cese completo de los síntomas descritos. DISCUSIÓN: La endometriosis profunda presenta un reto diagnóstico y habitualmente es tardío. Este caso presenta el resultado exitoso de una buena sospecha clínica, un estudio imagenológico completo y la resolución con una técnica quirúrgica compleja.

INTRODUCTION: Endometriosis is a disease that affects 10-15% of young women. It is characterized as functional endometrial tissue outside the uterine cavity. The most common form of presentation is dysmenorrhea. Deep endometriosis affects 1-2% of the patients, and is frequently located in the pelvic peritoneum, ovaries, utero-sacral ligaments and recto-vaginal septum. The isolated endometriosis of the sciatic nerve is a very uncommon presentation of this disease. Late diagnosis is frequent, mainly because the symptoms are non-specific, and the physical examination may be indistinguishable from other etiologies. The imaging study of choice is the pelvic magnetic resonance imaging (MRI) and an accurate pre-surgical location of the lesions is critical for a successful surgical outcome. CLINICAL CASE: 46-year-old female patient with 3 years of pelvic pain, dysmenorrhea and dyspareunia. The cardinal symptom was progressive sciatic pain, with motor deficit and sensory alterations. The pain was persistent despite pharmacological treatment and exacerbated during menstruation. MRI identifies a nodule located in the pelvic portion of the right sciatic nerve, suggestive of an endometriosis implant. The case was discussed by a multidisciplinary committee and laparoscopic surgery was performed. The diagnosis was confirmed with histology. The patient recovered well from surgery with significant improvement of the previously described symptoms. DISCUSSION: The diagnosis of deep endometriosis is challenging and usually delayed. This rare disease had a successful outcome, due to an early clinical suspicion, a thorough imaging study and an effective resolution with a complex surgical technique.
