LOW 25OHD IN ENDOMETRIOSIS- RISK FACTOR OR CONSEQUENCE?!

Active vitamin D-1.25OHD (1,25Dihydroxyvitamin D, calcitriol) in the endometrium of women with endometriosis seems to be enhanced compared to healthy controls. Evidence is insufficient on how this process reflects vitamin D metabolites-25OHD (25 Hydroxyvitamin D, calcifediol), 1.25OHD, and calcium blood concentrations. AIM: Determination of vitamin D's significance in the pathogenesis of endometriosis by analyzing the levels of 25OHD, 1.25OHD, and calcium in patients with endometriosis before and after laparoscopic treatment. MATERIALS AND METHODS: This study is an anterograde comparative analysis, that investigates the variation of vitamin D metabolite and calcium levels between the preoperative assessment and the subsequent measurement following surgical treatment of endometriosis. Results before the intervention were also compared to the healthy control group. Levels of 25OHD,1.25OHD, and calcium before required surgical treatment and 3 months post-laparoscopy were measured. Data analyses were made using IBM SPSS 27. RESULTS: Women with endometriosis have significantly lower mean 25OHD (p-0.002) and a higher 1.25OHD (p<0.001) and total calcium levels (p-0.03) compared to controls. The endometriosis stage and size of endometrioma negatively correlate with 25OHD levels (p<0.001). After surgical removal of endometriotic lesions, 1.25OHD, and calcium showed a significant decrease whereas 25OHD blood concentrations increased statistically significantly. CONCLUSION: Women with endometriosis have a lower 25OHD, a higher 1.25OHD, and total calcium levels in the bloodstream compared to the control group. Usually, a low concentration of 25OHD is characterized by low/normal 1.25OHD and hypocalcemia. Hypercalcemia in the study group may be attributed to increased levels of active vitamin D- 1.25OHD, which seems to be the result of a higher conversion rate of 25OHD to 1.25OHD in the endometrium of women with endometriosis. Removal of endometriotic heterotopies was followed by significant changes, which could indicate that the levels of vitamin D metabolites have been influenced by endometriosis. It is reasonable to conclude, that diminished levels of 25OHD might be interpreted as an outcome of a high demand in endometriosis, instead of a risk factor.

Pain after laparoscopic endometriosis-specific vs. hysterectomy surgeries: A retrospective cohort analysis.

OBJECTIVES: To evaluate pain perception and analgesic use between patients who underwent endometriosis-specific laparoscopic surgery compared to laparoscopic hysterectomy. MATERIAL AND METHODS: This retrospective cohort study included women diagnosed with endometriosis who underwent laparoscopic surgery from 1/2019 to 11/2022. The control group consisted of premenopausal women who underwent laparoscopic hysterectomy, which was considered a similarly extensive surgery. Demographics, preoperative and post-operative data were compared between groups. Post-operative pain scores on a visual analogue scale (VAS) between 0 (no pain) and 10 (worst pain) were compared between groups for each post-operative day (POD). Standard pain relief analgesia on POD 0-1 included fixed intravenous treatment with paracetamol and intramuscular diclofenac. The need for additional analgesics (morphine or dipyrone) beyond the standard pain relief protocol was compared between groups. RESULTS: Among 200 patients who underwent laparoscopic surgery, 100 (50%) were in the endometriosis group and 100 (50%) in the hysterectomy group. The endometriosis group was characterized by younger age and lower parity (both, p<0.001). There was no significant difference between the groups in mean VAS scores for each post-operative day. However, among patients who needed additional analgesics beyond the standard protocol on POD 1, a higher percentage of women in the endometriosis group used opioids rather than milder analgesics, as compared to controls (1% vs. 0.2%, respectively, p = 0.03). CONCLUSION: Increased post-operative morphine use was observed in patients with endometriosis following laparoscopic surgery, despite no significant difference in mean VAS scores during the post-operative days. These findings suggest that personalized pain relief protocols should be adjusted for women with endometriosis.

Revolutionizing endometriosis treatment: automated surgical operation through artificial intelligence and robotic vision.

Clinical limitations due to poverty significantly impact the lives and health of many individuals globally. Nevertheless, this challenge can be addressed with modern technologies, particularly through robotics and artificial intelligence. This study aims to address these challenges using advanced technologies in robotic surgery and artificial intelligence, proposing a method to fully automate endometriosis robotic surgery with a focus on interpretability, accuracy, and reliability. A methodology for fully automatic endometriosis surgery is introduced. Given the complexity of endometriosis lesions detection, they are categorized by their anatomical location to improve system interpretability. Then, three ensemble U-Net frameworks are designed to detect and localize common types of endometriosis lesions intraoperatively. A cross-training approach is employed, exploring U-Net models with diverse neural architectures-such as ResNet50, ResNet101, VGG19, InceptionV3, MobileNet, and EfficientNetB7-to develop U-Net ensemble models for precise endometriosis lesions segmentation. A novel image augmentation technique is also introduced, enhancing the segmentation models' accuracy and reliability. Furthermore, two U-Net models are developed to localize the ovaries and uterus, mitigating unexpected noise and bolstering the method's accuracy and reliability. The image segmentation models, assessed using the Intersection over Union (IoU) metric, achieved outstanding results: 97.57% for ovarian, 96.35% for uterine, and 92.58% for peritoneal endometriosis. This study proposes a fully automatic method for some common types of endometriosis surgery, including ovarian endometriomas and superficial endometriosis. This method is centered around three ensemble U-Net frameworks and a noise reduction technique using two additional U-Nets for localizing the ovaries and uterus. This approach has the potential to significantly improve the accuracy and reliability of robotic surgeries, potentially reducing healthcare costs and improving outcomes for patients worldwide.

The Role of Indocyanine Green With Near-Infrared Imaging for the Intraoperative Detection and Enhancement of Endometriosis Lesions: A Narrative Review.

Background: There is a clinical need for improved intraoperative detection of endometriosis, and the use of Indocyanine Green with Near-Infrared Imaging (NIR-ICG) is a novel technique for this purpose. The aim of this review is to determine whether NIR-ICG is an effective tool for endometriosis detection and establish an evidence-based methodology for its use.Methods: This review searches Ovid MEDLINE and Embase through July 2023 and considers primary literature published in English describing the use of NIR-ICG to detect endometriosis intraoperatively. Case studies, video demonstrations and articles describing NIR-ICG used for other surgical roles were not considered. Identified studies were screened independently by two authors, and data was extracted by a single author.Results: NIR-ICG was found to enhance the detection of endometriosis in six out of the nine included studies with additional lesion identification, and to have an unchanged or reduced efficacy compared to current standards in the remaining three. Across all studies there were lesions missed by NIR-ICG which were detected by conventional imaging. A greater duration of time between dye administration and visualisation of lesions was found to be more effective for detection. The ideal ICG protocol proposed from this review is a fixed amount of dye proportional to patient weight prior to surgery (0.25-0.3 mg/kg) followed by a longer waiting time before imaging (10-30 min).Conclusion: NIR-ICG has a possible role to enhance the identification of endometriosis intraoperatively as an adjunct to conventional white light imaging, particularly deeper infiltrating disease. However, substantial further research is required in this field.

Rectosigmoid Endometriosis Causing Large Bowel Obstruction.

Large bowel obstruction is most commonly due to colorectal carcinoma, diverticular disease or volvulus. Rare causes of large bowel obstruction like endometriosis may occur in premenopausal women and diagnosis of large bowel endometriosis can be challenging to confirm preoperatively. Hence, clinicians should maintain a high index of suspicion for rare causes of large bowel obstruction like endometriosis. This may require complete surgical resection of the involved bowel to eliminate the risk of local recurrence.

Is Complete Excision Always Enough? A Quality of Sexual Life Assessment in Patients with Deep Endometriosis.

Background and Objectives: The aim of this study was to find the factors associated with the severe impairment of QoSL and the factors associated with a better score in QoSL, as well as the evaluation of pain symptoms and QoSL after the complete and incomplete excision of rectovaginal nodules. Materials and methods: The present prospective study was conducted in a single tertiary center for endometriosis where 116 patients underwent laparoscopic surgery for deep endometriosis during a 3-year period. The goal of the intervention was to excise all endometriotic implants while conserving the rectum. Intraoperative findings were recorded after the intervention, and the patients were classified according to the ENZIAN classification and rASRM scores. QoSL was assessed using the EHP-30 Module C (QoSL Score). Results: When comparing the mean scores before and 2 years after the surgery, a highly significant improvement was found for QoSL and dysmenorrhea (p < 0.0001). The complete excision of rectovaginal nodules led to a significantly better QoSL and lower dyspareunia (p < 0.0001) than incomplete resection (p < 0.02). Conclusions: This prospective study proves that the complete laparoscopic excision of all endometriotic implants improved the QoSL and decreased the pain score of dyspareunia. Incomplete rectovaginal nodule excision was correlated with a poorer QoSL and a lower improvement of dysmenorrhea, dyspareunia, and chronic pelvic pain scores than complete excision.

Implementation and outcomes in benign gynecological surgery with HUGO™ RAS system 12 months initial experience.

We share our experience with the Hugo™ Robotic-Assisted Surgery system in benign gynecological surgeries. We retrospectively analyzed patients who underwent elective robotic surgeries for benign gynecological conditions at our surgical center from February 2023 to February 2024. Data collected included patient demographics, surgery indications, and outcomes. Perioperative data on port-placement time, arm configurations, docking, and console time were documented. Procedural outcome data including troubleshooting and overall satisfaction were also recorded. The primary outcome was perioperative data on port placement, docking time, arm configuration, and console time. The secondary outcome was defined as team satisfaction, system troubleshooting, arm repositioning, and complications graded 3-4 on the Clavien-Dindo Scale. A total of 60 patients underwent procedures for benign gynecological conditions using the Hugo™ RAS over the 12-month study period, primarily for pelvic endometriosis (53%), hysterectomies (27%), and adnexal surgery (10%). The mean port-placement time was 13 min and 41 s. In 31% of cases, low-port placement was used, with arm positioning being asymmetrical in 63% and symmetrical in 37%, demonstrating the system's flexibility in customizing port configurations while optimizing cosmetic outcomes. Docking time averaged 5 min and 51 s, and console time was 1 h and 5 min. Operational challenges included arm tremors and limited workspace for the assistant. This study details our knowledge using the Hugo™ RAS. Learning curves of port placement, arm positioning, docking, and procedure time can be rapidly adapted in a well-trained team. Our experience suggests the technology is still in its learning curve period.

Connecting the dots: Exploring appendiceal endometriosis in women with diaphragmatic endometriosis.

OBJECTIVES: This study aims to ascertain the prevalence of appendiceal endometriosis (AppE) in patients diagnosed with diaphragmatic endometriosis (DiaE), compare it with the prevalence in patients without DiaE, and delineate the anatomical distribution of endometriotic lesions within these cohorts. STUDY DESIGN: Comparison of the characteristics of patients with AppE and DiaE with the characteristics of patients with abdominal endometriosis without diaphragmatic involvement, in a prospective cohort study. SETTING: Tertiary referral center; endometriosis center. PATIENTS: A cohort of 1765 patients with histologically confirmed endometriosis INTERVENTIONS: Evaluation of correlations between demographic, clinical, and surgical variables of AppE patients with DiaE and without DiaE. We performed appendectomies selectively, in the presence of gross abnormalities of the appendix, such as endometriotic implants, edema, tortuosity, and discoloration of the organ. MEASUREMENTS: Patients' characteristics were evaluated using basic descriptive statistics (chi-square test or Fisher's exact test). A logistic regression analysis was performed to evaluate the relationship (hazard ratio) between patient characteristics and the presence of DiaE and AppE. MAIN RESULTS: Within a cohort of 1765 patients with histologically confirmed endometriosis, 31 were identified with AppE (1.8 %), and 83 with DiaE (4.7 %). The prevalence of DiaE was significantly elevated at 30.1 % (25/83), among patients with AppE compared to those without AppE, who showed a DiaE prevalence of 7.2 % (6/83). The calculated odds ratio for DiaE given the presence of AppE was 5.5, 95 % CI 2.1-14.4, p = 0.0004, and risk ratio was 4.2, 95 % CI 1.8-9.6, p = 0.0008, indicating a profound association. Surgical interventions did not lead to significant perioperative or postoperative complications. In the group with DiaE, the left ovary was affected in 96 % of cases (24/25), p < 0.05, the right ureter in 80 % of cases (20/25), p < 0.01 (in 19/25 only the serosa was affected, due to external compression of an endometriotic nodule of the parametrium). Concurrent AppE and right diaphragm was found in 92 % of cases (23/25 patients), p < 0.001. The concurrent presence of DiaE and AppE was often associated with severe endometriosis, rASRM IV 72 % OR = 3, 95 % CI (1.216-7.872). CONCLUSION: The investigation delineates a marked association between AppE and DiaE, with an odds ratio of 5.5 and risk ratio of 4.2, suggesting a markedly increased likelihood of DiaE in patients with AppE. These statistics significantly substantiate the notion that AppE can serve as a predictive marker for DiaE, underscoring the necessity for a meticulous intraoperative assessment of diaphragmatic regions in patients diagnosed with AppE. The absence of a significant correlation between the depth of DiaE infiltration and the presence of AppE implies that the detection of AppE should prompt a thorough search for DiaE, regardless of the perceived severity of the endometriosis or preoperative results of diaphragmatic MRI.

Cesarean section incision along the posterior uterine wall - an obstetric and surgical complication of an obstructed pelvis due to previous endometriosis.

Pelvic endometriosis is a well-known clinical risk factor for pelvic inflammation and adhesions. We present a complex case of a woman undergoing a cesarean section where the traditional incision on the anterior lower uterine segment was not possible due to a congested pelvis. The newborn was delivered using a posterior uterine wall incision with rotation of the round ligament.

Progesterone receptor B over progesterone receptor A prevents recurrence in bilateral endometriomas.

OBJECTIVE: Endometriosis is a disease in which stromal cells and endometrial glands extend outside of the uterine cavity. Nevertheless, treatment failure and recurrence cause difficulties in management. This study aimed to evaluate the receptor-level components of bilateral endometriomas in the recurrence state. METHODS: Our retrospective cohort study was conducted with patients who underwent surgery for bilateral endometriomas between 2015 and 2021. In total, 113 patients were allocated. A total of 76 patients did not meet the eligibility criteria, and the data of 37 patients were evaluated. Medical treatments, recurrences, and postoperative follow-up data were collected. In archived tissue samples, measurements of progesterone receptor A and progesterone receptor B, histoscores and immunoreactivity scores, and their ratios were calculated in the group that received no postoperative medical treatment. Criteria for recurrence were a repeat operation and/or the detection of a new endometrioma>2 cm at the follow-up examination. RESULTS: No recurrence was observed in 73.0% (n=27) of the cases, whereas recurrence was observed in 27.0% (n=10) of the participants. Patients without recurrence had significantly higher progesterone receptor B histoscore/progesterone receptor A histoscore and progesterone receptor B immunoreactivity score/progesterone receptor A immunoreactivity score results (p=0.01). Nevertheless, when the histoscores and immunoreactivity scores for both receptors were contrasted separately, there was no appreciable difference between them. CONCLUSION: The dominance of progesterone receptor B over progesterone receptor A was inversely proportional to the recurrence status in bilateral endometriomas. Furthermore, our study revealed that assessing receptor levels alone did not result in a significant difference in recurrence.

Effects of pretreatment with long-acting gonadotropin-releasing hormone agonists on pregnancy outcomes in patients with minimal and mild peritoneal endometriosis: A retrospective study of 274 frozen-thawed embryo transfer cycles.

To investigate the effects of pretreatment with long-acting gonadotropin-releasing hormone agonist (GnRH-a) before frozen-thawed embryo transfer (FET) on pregnancy outcomes in patients after minimal-mild (stages I-II) peritoneal endometriosis surgery. A retrospective cohort study was performed from March 2018 to May 2019. Overall, 274 patients met inclusion criteria of undergoing FET after minimal/mild peritoneal endometriosis surgery. For the FET protocol, patients were divided into 2 groups: GnRH-a plus hormone replacement therapy (HRT) (group A, n = 154) and HRT-only (group B, n = 120), with the former divided into 2 subgroups receiving 1 (group A1, n = 80) or 2 doses (group A2, n = 74) of GnRH-a. Basic characteristics and pregnancy outcomes of groups A and B and groups A1 and A2 were compared. Clinical pregnancy rate (CPR) and live birth rate (LBR) were the primary outcomes and logistic regression was used to analyze independent correlation factors. The CPR and LBR in group A were 58.4% and 50.0%, respectively, and were not significantly higher than in group B (49.2% and 40.0%; respectively, χ2 = 2.339, P = .126 and χ2 = 2.719, P = .099, respectively). CPR and LBR in group A1 were not significantly lower than those in group A2 (52.5% and 45.0% vs 64.9% and 55.4%, respectively; χ2 = 2.420, P = .120 and χ2 = 1.665, P = .197, respectively). However, group A2's CPR and LBR were significantly higher than group B's (64.9% and 55.4% vs 49.2% and 40.0%, respectively; χ2 = 4.560, P = .023 and χ2 = 4.375, P = .026, respectively). Logistic regression analysis showed that GnRH-a pretreatment (1 or 2 doses) had no significant effect on CPR and LBR compared with the HRT-only group. Patients with minimal-mild (stages I-II) peritoneal endometriosis surgery may not require GnRH-a pretreatment before FET.

Continued improvement to imaging diagnosis and treatment triage of endometriosis: The role of the multi-disciplinary conference.

Patient-centered endometriosis management tailored to the individual patient's subset of symptoms often requires highly sensitive and specific preoperative imaging. In the setting of a present ongoing learning curve among radiologists who interpret pelvis ultrasounds and MRIs for diagnosis of endometriosis, we have found that routine feedback between minimally invasive gynecology surgeons and radiologists, based on pre-operative imaging and postoperative laparoscopic findings, is essential for the continual improvement of imaging-based staging of endometriosis and empower pre-operative imaging as an important pillar of endometriosis management. We share illustrative patient cases, which, after collaborative discussion during our routine multi-institutional, multi-disciplinary conferences (MDCs) have led to improved patient counseling, better pre-surgical planning, and therefore improved patient satisfaction. Our endometriosis MDCs will continue to improve patient management in the future by providing a forum for trainees in medical, surgical, imaging, and pathology specialties to gain expertise directly from subspecialists, and participate in the care of these patients.

Distribution of endometriosis phenotypes according to patients' age in adult women with surgical evaluation.

STUDY QUESTION: What is the distribution of endometriosis phenotypes according to age in adult women undergoing surgery? SUMMARY ANSWER: The phenotype of endometriosis did not significantly vary after 24 years old. WHAT IS KNOWN ALREADY: The phenotypic evolution of endometriosis over time remains unclear. While adolescents can exhibit any type of endometriosis lesions, ovarian endometriosis (OMA) and/or deep-infiltrating endometriosis (DIE) tend to increase with age in young adults. In adulthood, understanding the evolution of lesions is crucial for disease management, but the literature on this subject is limited. This study aims to examine the distribution of endometriosis phenotypes in relation to age among adult patients requiring surgical treatment. STUDY DESIGN, SIZE, DURATION: This observational cohort study included patients aged between ≥18 and ≤42 years, who underwent surgery for benign gynecological conditions at our institution between January 2004 and December 2022. A standardized questionnaire was completed for each patient during a face-to-face interview conducted by the surgeon in the month preceding surgery. Women with histologically proven endometriosis were included. PARTICIPANTS/MATERIALS, SETTING, METHODS: The distribution of endometriosis phenotypes (isolated superficial (SUP) endometriosis, OMA ± SUP, DIE ± SUP/OMA) was compared between young adults (≤24 years) and adults (>24 years) and among adults (25-28 years, 29-33 years, 34-38 years, 39 to ≤42 years) using univariate and multivariate analysis. The distribution of different subtypes of DIE (uterosacral ligament(s), vagina, bladder, intestine, and ureter), OMA size, and intensity of pain symptoms were also examined. MAIN RESULTS AND THE ROLE OF CHANCE: A total of 1311 adult women with histologically proven endometriosis were included. In women aged 24 years or younger (n = 116), the distribution of endometriosis phenotypes differed significantly from women older than 24 years (n = 1195): The frequency of the DIE ± SUP/OMA phenotype was lower (41.4% versus 56.1%, respectively), while the rate of isolated superficial lesions was higher (from 32.0% versus 25.9%) (P = 0.001). In the group of women aged >24 years, a significantly higher proportion of vaginal DIE lesions (P = 0.012) and a lower proportion of uterosacral ligament DIE lesions (P = 0.004) were found compared to women aged ≤24 years. No significant differences were observed in terms of endometrioma size. Between the ages of 25 and 42 years, there were no significant changes in the distribution of endometriosis phenotypes after univariate and multivariate analysis. The distribution of subtype of DIE lesions did not significantly change with age between 25 and 42 years. Concerning pain symptom scores, there was a significant decrease with age for dysmenorrhea and dyspareunia. LIMITATIONS, REASONS FOR CAUTION: Inclusion of only surgical patients may have introduced a selection bias. Women referred to our center may have suffered from particularly severe clinical forms of endometriosis. WIDER IMPLICATIONS OF THE FINDINGS: This study highlights that endometriosis presentation did not change with age in adult women. Further research on endometriosis phenotype evolution is necessary to assist practitioners in clinical decisions and treatment strategies. STUDY FUNDING/COMPETING INTERESTS: None declared. TRIAL REGISTRATION NUMBER: N/A.

Bladder Endometriosis: What do we know and what is left to find out? A narrative review.

Bladder endometriosis accounts for 70-85% of urinary tract endometriosis cases. Urinary tract endometriosis occurs in approximately 1% of those living with endometriosis. Underlying aetiology and pathogenesis are not fully understood, but there are several plausible theories. As well as the typical pain symptoms, those with bladder endometriosis can experience several urinary tract symptoms. The manifestation of these symptoms can have complex pathways and processes. Imaging is accurate in the diagnosis of bladder endometriosis and clinicians should be mindful of the risk of silent kidney loss. Management should be guided by symptoms; both medical and surgical options are feasible. Surgical management offers potentially definitive treatment. Excisional surgery via bladder shave or partial cystectomy offers good improvement in symptoms with relatively low rates of serious complications and recurrence.

Endometriosis of the appendix: prevalence, associated lesions, and proposal of pathogenetic hypotheses. A retrospective cohort study with prospectively collected data.

OBJECTIVE: To assess the prevalence of endometriosis of the appendix and the association with other pelvic localizations of the disease and to provide pathogenesis hypotheses. METHODS: Monocentric, observational, retrospective, cohort study. Patients undergoing laparoscopic endometriosis surgery in our tertiary referral center were consecutively enrolled. The prevalence of the different localizations of pelvic endometriosis including appendix involvement detected during surgery was collected. Included patients were divided into two groups based on the presence of appendiceal endometriosis. Women with a history of appendectomy were excluded. MEASUREMENTS AND MAIN RESULTS: Four hundred-sixty patients were included for data analysis. The prevalence of appendiceal endometriosis was 2.8%. In patients affected by endometriosis of the appendix, concomitant ovarian and/or bladder endometriosis were more frequently encountered, with prevalence of 53.9% (vs 21.0% in non-appendiceal endometriosis group, p = 0.005) and 38.4% (vs 11.4%, p = 0.003), respectively. Isolated ovarian endometriosis was significantly associated to appendiceal disease compared to isolated uterosacral ligament (USL) endometriosis or USL and ovarian endometriosis combined (46.2% vs 15.4% vs 7.7%, p < 0.001). Poisson regression analysis revealed a 4.1-fold and 4.4-fold higher risk of ovarian and bladder endometriosis, respectively, and a 0.1-fold risk of concomitant USL endometriosis in patients with appendiceal involvement. CONCLUSION: Involvement of the appendix is not uncommon among patients undergoing endometriosis surgery. Significant association was detected between appendiceal, ovarian, and bladder endometriosis that may be explained by disease dissemination coming from endometrioma fluid shedding. Given the prevalence of appendiceal involvement, counseling regarding the potential need for appendectomy during endometriosis surgery should be considered.

Comparison of surgical outcomes between robot-assisted and conventional laparoscopic nerve-sparing modified radical hysterectomy for deep endometriosis.

PURPOSE: Drug resistance and severe pelvic pain often warrant surgical intervention for treating deep endometriosis (DE); however, damage to the autonomic nervous system can occur because of anatomical considerations. We aimed to investigate the advantages of robotic technology in enabling precise dissection, even in DE. METHODS: We retrospectively compared the surgical outcomes of robot-assisted (RA) and conventional laparoscopic (CL) nerve-sparing modified radical hysterectomies (NSmRHs) for DE. RESULTS: Between the two groups (RA-NSmRH group, n = 50; CL-NSmRH group, n = 18), no differences were identified based on patient demographics, such as age, body mass index, previous surgery, revised American Society of Reproductive Medicine classification, Enzian classification, uterine weight, number of removed DE lesions, and concomitant procedures. All patients in both groups achieved complete removal of the DE lesions with complete bilateral pelvic autonomic nerve preservation. The mean operative time (OT) was significantly longer (130 ± 46 vs. 98 ± 22 min, p < 0.01), and estimated blood loss (EBL) was lower (35 ± 44 vs. 131 ± 49 ml, p < 0.01) in the RA-NSmRH group than in the CL-NSmRH group. The hospitalization days (4.3 ± 1.3 vs. 4.1 ± 0.2 days, p = 0.45) and perioperative complications with Clavien-Dindo classification ≥ grade III (0% vs. 0%) were not significant in both the groups. None of the patients required self-catheterization after surgery. CONCLUSION: Compared with CL-NSmRH, RA-NSmRH was associated with longer OT and lower EBL, whereas the number of hospitalization days and complications were similar in both groups. Our results imply that nerve-sparing surgery can be safely and reproducibly performed using conventional or robotic laparoscopic modalities to treat DE.

Systematic use of intraureteral indocyanine green: a game changer in endometriosis surgery. A proof-of-concept study.

BACKGROUND: Endometriosis of the distal segment of the uterosacral ligament may lead to a displaced ureter in the surgical field and must be identified before safe disease excision can be carried out. The aim of this study is to investigate the benefit of the systematic use of preoperative intraureteral indocyanine green (ICG) fluorescence injection in patients undergoing endometriosis surgery. METHOD: In this proof-of-concept, monocentric, observational, cohort study data were prospectively collected and retrospectively analyzed. Patients underwent laparoscopic surgery for deep infiltrating endometriosis with suspected ureteral involvement between January 2022 and December 2023. Using the propensity score matching (PSM) in a 1:1 matching ratio, patients who underwent preoperative ICG injection were compared with those who did not in terms of ureterolysis length and duration, and operative time. RESULTS: The mean length of ureterolysis was shorter in the ICG group compared to the non-ICG group (p < 0.001). The ICG group also had shorter ureterolysis duration (p < 0.001) and operative time (p = 0.02). No complications were reported at mean 6.8-month follow-up visit. CONCLUSIONS: The systematic use of intraureteral ICG prior to uterosacral ligaments endometriosis surgery may be safe and could assist in reducing the length of ureterolysis and operative time. Larger prospective studies are needed to confirm our findings.

Rare Broad Ligament Cavernous Hemangioma Mimicking Advanced Endometriosis: A Case Report.

Cavernous hemangioma within the female genital tract is an extremely rare pathology, characterized by irregular vascular spaces containing blood or thrombus. We present a unique case of a 42-year-old primiparous woman who presented with typical endometriosis symptoms such as dysmenorrhea, dyspareunia, and heavy menstrual bleeding. The patient also experienced complex postpartum symptoms, which were misdiagnosed as cholecystitis and retained placental products. Imaging studies suggested deep infiltrative endometriosis with extraovarian endometriotic lesions. Surgical exploration revealed a hemangioma within the right anterior broad ligament alongside peritoneal endometriosis lesions. The hemangioma itself expresses estrogen and progesterone receptors in stromal cells. The presence of steroid hormone receptors strongly suggests symptom alleviation during the menstrual cycle and the postpartum period. The coexistence of cavernous hemangioma and endometriosis in the broad ligament, previously unreported, and symptomatic overlap between the two conditions complicates diagnosis and management, emphasizing the need for comprehensive evaluation integrating clinical symptoms and imaging findings.

A new treatment for Robert's uterus with adenomyosis: a case report and review of the literature.

PURPOSE: To provide a method for the differential diagnosis of Robert's uterus with adenomyosis, a rare uterine malformation, and determine the best course of treatment. METHODS: A patient who had Robert's uterus with adenomyosis was admitted to our hospital in December 2022. We analyzed and summarized her case . RESULTS: Our patient complained of progressively worsening primary dysmenorrhea over the course of 3 years and lower abdominal pain lasting for 2 days. Her carbohydrate antigen 125 (CA125) level was 372.10 U/mL. Examinations conducted by several hospitals indicated that she had a single-horned uterus and a residual horned uterus, and our hospital's examination identified Robert's uterus. This malformation was corrected by open abdominal surgery. For the procedure, pelvic adhesions were first isolated, after which the closed uterine cavity and adenomyosis were resected. Subsequently, the left ovarian endometriosis cyst was resected and right tubal ligation was performed. After surgery, three injections of gonadotropin-releasing hormone A (GnRH-A) were administered, which lowered the patient's CA125 level to 14 U/mL and normalized her condition. CONCLUSION: We pioneered a new therapeutic approach for the treatment of Robert's uterus with adenomyosis. Some valuable references are provided for clinical practice.
