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.

5,926 hysterectomies: complications described by Clavien-Dindo classification.

Hysterectomy is the most common major gynaecological surgery. Due to its high volume, the analysis of its results is relevant. The objective of this study was to describe intraoperative complications and reoperations, for both benign and malignant causes, using the Clavien-Dindo classification (approved by local ethics committee, number 100220). Between 2000 and 2019, 5926 elective hysterectomies were performed, of which 90.2% were for benign aetiology and 9.8% for malignant causes. The abdominal route was 52.7%, vaginal 40.1% and laparoscopic 7.2%. Intraoperative complications and reoperations (grade III Clavien-Dindo) were 4% and 2.1%, respectively. Oncological surgery had significantly more intraoperative complications (10% vs. 3.4%) and reoperations (3.6% vs. 1.9%) than benign procedures. Noteworthy, intraoperative complications required a new operation in only 3.4% for malignant and 2.8% for benign surgery. Our data showed the relevance of detecting and rectifying intraoperative complications during surgery, which consequently leads to a lower reoperation rate, minimising postoperative morbidity and mortality for patients.Impact StatementWhat is already known on this subject? The surgical complications of hysterectomy, both intraoperative and postoperative, are extensively described. However, this information is not well systematised, in which elective and emergency surgery are mixed. In addition to the above, there are few documents comparing the results of hysterectomies due to benign versus malignant causes.What the results of this study add? Using the Clavien-Dindo classification, this study adds an organised description of intraoperative complications and reoperations of hysterectomy in the context of elective surgery. In addition, it provides information on the comparison between surgery for benign versus malignant causes, as well as information on intraoperative complications requiring a new operation.What the implications are of these findings for clinical practice and/or further research? These findings provide clear and orderly data about the risks of elective hysterectomy and showed the relevance of detecting and rectifying intraoperative complications during the procedure. This is useful for specialists to preoperatively identify the risks for each hysterectomy group and provide their patients with more detailed information during informed consent.

Incidence of occult uterine sarcoma and other unexpected pathologies in patients having surgery for presumed myomas: A retrospective observational study.

OBJECTIVE: To determine the incidence of occult uterine sarcomas and other unexpected pathologies in patients undergoing hysterectomies or myomectomies with a pre-operative diagnosis of uterine leiomyomas. STUDY DESIGN: Retrospective study. SETTING: Tertiary hospital in Santiago, Chile. POPULATION: 921 women who underwent surgery for presumed myomas. Database analysis of surgical and pathological notes, from January 2007 to December 2017 with a preoperative diagnosis of uterine leiomyoma. MAIN OUTCOME MEASURES: number of patients with uterine sarcoma confirmed on histology. RESULTS: During this period, a total of 921 gynecological surgeries were performed for benign uterine fibroids of which 787 were hysterectomies and 134 were myomectomies. We found four cases of malignant neoplasms (0,43 %). Two were uterine leiomyosarcoma (LMS), one mixed epithelial and mesenchymal tumor, and one case of incidental cervical cancer. This gives an LMS incidence of 1 in 460 and 1 in 921 of mixed epithelial and mesenchymal tumor. There were seven cases of unexpected benign pathology. This included six atypical myomas and one leiomyoblastoma epithelioid myoma. If we combine the malignant and benign cases, we would have an incidence of 1.2 % of unexpected pathology. CONCLUSION: In our series of patients undergoing myomectomies or hysterectomies for presumed myomas the incidence of LMS was 1 in 460. The incidence of any unexpected pathology including benign ones in presumed myomas was 1 in 83 (six atypical myomas, one leiomyoblastoma epithelioid myoma, two LMS, one mixed epithelial and mesenchymal tumor, one incidental cervical cancer).

Ergonomía en cirugía laparoscópica ginecológica / Ergonomics and gynecologic laparoscopic surgery

INTRODUCCIÓN Y OBJETIVOS: Están demostradas las ventajas de la cirugía laparoscópica para el paciente en términos de dolor, rápida recuperación y precisión quirúrgica, sin embargo, no existen estudios nacionales respecto al impacto en los cirujanos. El objetivo de este trabajo es realizar un estudio prospectivo de evaluación ergonómica de ginecólogos que operan cirugía laparoscópica. MÉTODOS: Se utilizaron métodos de evaluación específica por ergónomo experto y percepción de los participantes. Se evaluaron, carga global de trabajo (NASA-tlx), carga bio-mecánica (REBA) y la percepción de molestias músculo-esqueléticas (Escala de Discomfort Corporal). Se recogieron datos personales y de la cirugía, para explorar la existencia de dificultades técnicas. RESULTADOS: 86,7% de los ginecólogos evidenciaron altos niveles de carga global de trabajo, siendo las variables esfuerzo y rendimiento, las de mayor puntaje. El nivel de riesgo bio-mecánico, fue catalogado como medio en la totalidad de la población. 60% manifestó discomfort corporal durante la cirugía. En cuanto a las dificultades técnicas, el efecto fulcrum estuvo presente en el 46% de los cirujanos, el mismo porcentaje tuvo síntomas de ojo seco. El 68% alguna vez accionó el pedal equivocado y ha sentido parestesia del pulgar. CONCLUSIONES: La cirugía laparoscópica ginecológica, presenta una elevada carga global de trabajo. El ginecólogo percibe un importante discomfort corporal y algunas dificultades técnicas. Es necesario incorporar medidas ergonómicas, para minimizar y/o disminuir los factores de riesgo mental y físicos, y así prevenir el desgaste precoz y lesiones a futuro en los cirujanos.

INTRODUCTION AND OBJECTIVES: Laparoscopic surgery had demonstrated advantages such as less pain, rapid recovery and surgical precision. There are no national data regarding the impact on surgeon's health. This is a prospective study on ergonomic evaluation and laparoscopic surgery performed by gynecologists. METHODS: Specific evaluation methods were used such as Global workload (NASA-tlx), bio-mechanical load (REBA) and the perception of musculoskeletal discomfort (Body Part Discomfort Scale). Personal opinions and surgery data were collected to explore the existence of technical difficulties. RESULTS: 86.7% of gynecologists cataloged surgery as high level of global workload. Effort and performance variables were most important. Bio-mechanical risk level was classified as medium in the entire population. 60% showed body discomfort during surgery. Regarding technical difficulties, fulcrum effect was present in 46% of surgeons, the same percentage had dry eye symptoms. 68% have a pedal error activation during surgery and felt paresthesia of the thumb. CONCLUSIONS: Gynecological laparoscopic surgery has a high overall workload. The gynecologist perceives an important body discomfort and some technical difficulties. It is necessary to incorporate ergonomic measures, to minimize and / or reduce mental and physical risk factors, and thus prevent early wear and future injuries in surgeons.

Histeroscopía quirúrgica: experiencia, resultados y complicaciones según clasificación Clavien-Dindo / Surgical hysteroscopy: experience, results and complications according to Clavien-Dindo classification

OBJETIVO: Describir y analizar la experiencia clínica, resultados y complicaciones según Clavien-Dindo de las histeroscopías quirúrgicas realizadas en pabellón. MÉTODOS: Estudio descriptivo retrospectivo de las histeroscopías quirúrgicas realizadas entre el 1 de enero de 2012 y 1 de enero de 2018 en el Hospital Clínico de la Universidad de Chile. RESULTADOS: Hubo 613 histeroscopías quirúrgicas en el período analizado, de las cuales 593 cumplieron con los requisitos para incluirse en este estudio. Las indicaciones para realizar el procedimiento fueron: pólipo endometrial (56,3%), miomas uterinos (22,1%), sangrado uterino anormal (4,3%) y otras (17,7%). Hubo un 89,2% de concordancia entre el diagnóstico intraoperatorio y el estudio histopatológico. Se pesquisaron 11 hiperplasias endometriales sin atipías, 3 con atipías y 10 neoplasias malignas. Cabe destacar que, del total de pólipos resecados, hubo 8 casos (2,5%) con potencial malignidad (atipías o neoplasia maligna). Según la clasificación Clavien Dindo, hubo 22 complicaciones intraoperatorias (3,7%) grado I o II, cuyo diagnóstico fue realizado en el acto quirúrgico. No hubo complicaciones grado III o más (severas, con reintervención). CONCLUSIÓN: La tasa de éxito, correlación histeroscópica - anatomopatológica final y complicaciones fue similar a lo publicado en la literatura disponible. El diagnóstico intraoperatorio de la lesión y su reparación en el mismo acto quirúrgico, disminuye el riesgo de morbimortalidad de las pacientes, haciéndolo similar al de una paciente sin complicación. Utilizar la clasificación Clavien Dindo para evaluar las complicaciones nos permitirá en adelante, objetivar, mejorar aspectos del procedimiento quirúrgico y plantear estrategias de prevención y manejo de dichos eventos adversos.

OBJECTIVE: To describe and analyze the clinical experience, results and complications according to Clavien-Dindo of surgical hysteroscopies performed in the ward. METHODS: Retrospective descriptive study of surgical hysteroscopies performed between January 1, 2012 and January 1, 2018 at the Hospital Clinico of the University of Chile. RESULTS: There were 613 surgical hysteroscopies in the analyzed period of which 593 fulfilled the requirements to be included in this study. The indications to perform the procedure were: endometrial polyp (56.3%), uterine fibroids (22.1%), abnormal uterine bleeding (4.3%) and others (17.7%). There was an 89.2% agreement between the intraoperative diagnosis and the histopathological study. Eleven endometrial hyperplasias without atypia, 3 with atypia and 10 malignant neoplasms were investigated. It should be noted that, of the total of resected polyps, there were 8 cases (2.5%) with potential malignancy (atypia or malignant neoplasm). According to the Clavien Dindo classification, there were 22 intraoperative complications (3.7%) grade I or II, the diagnosis of which was made during surgery. There were no grade III or more complications (severe, with reoperation). CONCLUSION: The success rate, final hysteroscopic-pathological correlation and complications was similar to that published in the available literature. The intraoperative diagnosis of the lesion and its repair in the same surgical act, reduces the risk of morbidity and mortality of the patients, making it similar to that of a patient without complication. Using the Clavien Dindo classification to assess complications will henceforth allow us to objectify, improve aspects of the surgical procedure and propose strategies for the prevention and management of such adverse events.

Laparoscopic surgery for severe ureteric endometriosis.

OBJECTIVES: To describe the outcomes of laparoscopic surgery for severe ureteric endometriosis. STUDY DESIGN: Retrospective descriptive study of the clinical and surgical outcomes for patients who underwent laparoscopic surgery for severe ureterohydronephrosis due to endometriosis. The surgery consisted of laparoscopic ureterolysis, ureteric end-to-end anastomosis and ureteral stenting at the Department of Obstetrics and Gynecology, Strasbourg Hospitals, between June 2004 and June 2009. Data were collected from patients' notes and also included telephone interview. Normally distributed data are presented as mean ± SD, and skewed data as median (range). Categoric variables are reported as absolute values and percentages. Continuous variables are compared using the paired samples t-test. Statistical significance was set at P<0.05. RESULTS: Thirteen patients had severe disease. Two patients had non-functioning kidneys. Left sided lesions were more common (76.9%). All patients had associated deep infiltrative endometriosis (DIE) elsewhere in the pelvis. Laparoscopic treatment was feasible in all cases without the need to convert. Ureterolysis was performed in seven patients (53.8%) and segmental resection with end-to-end anastomosis in six (46.2%) patients. Ureteric wall endometriotic infiltration was present in four cases (30.8%). Median follow up duration was 24 months. All patients had improvement of their pain symptoms. There were no intraoperative complications. Major postoperative complications were seen in three patients (23%). CONCLUSIONS: Ureteric involvement is usually asymptomatic, and therefore in patients with evidence of deep endometriosis it must be excluded by ultrasound or magnetic resonance imaging. Laparoscopic treatment of ureteric endometriosis is feasible. Intrinsic ureteric endometriosis is quite frequent in severe ureterohydronephrosis. Complete excision of the disease is essential to improve pain symptomatology and to prevent recurrence of disease. Long term follow up is required to exclude any stenosis.

Long-term urinary retention after laparoscopic surgery for deep endometriosis.

OBJECTIVE: To report on chronic urinary retention after surgery for deep endometriosis and the possible risk factors for this complication. DESIGN: Descriptive study. SETTING: University hospital. PATIENT(S): Four patients with deep endometriosis who developed this complication. INTERVENTION(S): Laparoscopic surgery, intermittent self-catheterization (ISC). MAIN OUTCOME MEASURE(S): To identify site(s) of lesion associated with this complication. RESULT(S): Four patients developed this complication from damage to the inferior hypogastric plexus involving the sympathetic and/or parasympathetic afferents from the bladder. One patient regained complete bladder function 8 months after surgery, and the others required ISC at the time of writing (13, 24, and 3 months after surgery). Patients with lesions located laterally and deep in the uterosacral ligaments especially near the ischial spines were at high risk. All patients were, however, satisfied with the results of surgery. CONCLUSION(S): Most such injuries are unpredictable, but in our experience, two of three patients with lesions near the ischial spine developed this complication. Chronic urinary retention after radical endometriosis surgery is rare and often under reported. Although most lesions are unilateral and have a potential for improvement, it is not known how long these effects will last. More data from other centers may help in providing additional information.

Endometriosis of bladder: outcomes after laparoscopic surgery.

STUDY OBJECTIVE: To describe outcomes after laparoscopic excision of deep bladder endometriosis. DESIGN: Retrospective study (Canadian Task Force classification II-3). SETTING: University hospitals. PATIENTS: Twenty-one consecutive patients with endometriotic nodule on the bladder (infiltrating detrusor muscle) from a series of 169 patients were included in the study. The primary outcome studied was resolution of bladder symptoms. Secondary outcomes included complication rates, recurrence rates, and pregnancy rates after laparoscopic surgery. INTERVENTIONS: Laparoscopic excision of bladder endometriosis. MEASUREMENTS AND MAIN RESULTS: Laparoscopy was feasible in all cases without the need for conversion. Median follow-up was 20 months. Ten patients (47.6%) underwent partial cystectomy, and the remaining patients underwent partial-thickness excision of the detrusor muscle. Sixteen patients (76%) had associated deep lesions in the pelvis. The most common associated lesions were rectovaginal nodules (38%) and ureteric lesions (14%), with signs of obstruction. Major complications developed in 3 patients (14%), primarily related to bowel resection. Six patients became pregnant (60%). No patients experienced disease recurrence. CONCLUSION: Laparoscopic excision is feasible in all types of bladder endometriosis but often involves multiple procedures to manage associated lesions, especially rectovaginal nodules and ureteric lesions. Previous reports have suggested that ureteric lesions are not associated with bladder endometriosis; however, this was not true in our series. Complications are primarily related to severity of the disease and associated procedures. Partial cystectomy is not required in all cases to achieve adequate clearance. Complete excision of the disease is associated with resolution of bladder symptoms and low recurrence rates.

Hematometra following laparoscopic resection of retrocervical and rectovaginal endometriosis.

OBJECTIVE: To report a case of hematometra following laparoscopic resection of rectovaginal endometriosis extending to the cervix. DESIGN: Case report. SETTING: University hospital. PATIENT(S): A 31-year-old woman with endometriosis and infertility. INTERVENTION(S): Combined laparoscopic and vaginal surgery. RESULT(S): The cervix had retracted into the vaginal scar after surgery, preventing the escape of menstrual blood. The hematometra was drained, and the cervix was repositioned into the vagina with use of a combined vaginal and laparoscopic approach. CONCLUSION(S): Retraction of the cervix into the cul-de-sac can occur as a complication of excision of rectovaginal nodules that extend onto the posterior surface of the cervix. Excision of the posterior cervix should avoid deep excision of the posterior lip and should be limited only to the ectocervical margin to avoid such complications.
