Low rectal resection for low rectal endometriosis and rectal adenocarcinoma: Are we discussing the same risks?

OBJECTIVE: To evaluate the rate and risk factors for anastomosis leakage in patients undergoing colorectal resection with low anastomosis for rectal endometriosis and rectal adenocarcinoma. METHODS: A retrospective cohort study evaluating prospectively collected data was conducted. Patients undergoing colorectal resection for rectal endometriosis and rectal adenocarcinoma with low anastomosis (<7 cm from the anal verge [AV]) from September 2018 to January 2023 were included in the analysis. The main outcome was the rate of anastomosis leakage. A multivariate logistic regression was conducted to evaluate risk factors for anastomosis leakage in both groups. RESULTS: A total of 159 patients underwent colorectal resection with low anastomosis due to rectal endometriosis (n = 99) and rectal adenocarcinoma (n = 60). Patients with endometriosis were significantly younger than those with adenocarcinoma (35.7 ± 5.1 vs 63.7 ± 12.6; P = 0.001). The leakage rate was similar between the endometriosis (n = 12, 12.1%) and adenocarcinoma (n = 9, 15.0%) patients (P = 0.621). The anastomosis height less than 5 cm from the AV (adjusted odds ratio [aOR] 12.12, 95% confidence interval [CI] 2.24-23.54) was significantly associated with the anastomosis leakage. Protective stoma was associated with the decrease of the leakage risk (aOR 0.12, 95% CI 0.01-0.72). The type of disease (rectal endometriosis or adenocarcinoma) was not associated with the anastomosis leakage (aOR 2.87, 95% CI 0.34-21.23). CONCLUSIONS: Despite the different pathogenesis, the risk of anastomotic leakage was found to be similar between patients with low rectal endometriosis and those with rectal adenocarcinoma. These results must be considered by the gynecologist and colorectal surgeon to deliver proper information before rectal surgery for endometriosis.

Bowel endometriosis: Surgical customization is demanding.

Bowel endometriosis is the most common form of severe deep endometriosis. Surgery is an option in case of infertility and/or chronic pain or in the presence of a stenotic lesion. Clinical examination and preoperative imaging must provide an identity card of the lesion so that customized surgery can be proposed. The primary objective of this tailor-made surgery will always be to preserve the organ. The surgeon then has three options: shaving, discoid resection and segmental resection. The more extensive the resection, the greater the risk of severe short- and long-term complications. Surgery must therefore be adapted to the patient's specific situation and needs. Moreover, personalized care must extend beyond surgery. It must begin before the operation, preparing the patient for the operation like an athlete before a race, and continue afterwards by adapting the follow-up to the surgery performed.

Combined Decompression of Pudendal and Inferior Cluneal Nerves for Entrapment Neuralgias Using Transperitoneal Robotic Laparoscopy: Feasibility and Our 4 Step Technique.

OBJECTIVE: To demonstrate the feasibility of a combined decompression of pudendal and inferior cluneal nerves for entrapment syndrome using a transperitoneal robotic laparoscopy. DESIGN: Demonstration of our 4-step technique with narrated video footage. SETTING: Pudendal and inferior cluneal neuralgias caused by an entrapment syndrome are both responsible for perineal pain [1]. Although more precise data are lacking, these 2 neuralgias are frequently associated. Failure of surgical pudendal nerve decompression in the early 2000 has driven to discover the entity of a potential entrapment syndrome of the posterior cutaneous nerve of the tight and its inferior cluneal branches between the ischium bone and the sacrotuberous ligament [2]. The corresponding neuralgia is responsible for a neuropathic pain to a more posterior part of the perineum and the thigh, without any neurovegetative symptom. In case of failure of medical treatment, surgery can be proposed using an invasive open transgluteal approach as a standard treatment [3-5]. INTERVENTIONS: Transperitoneal robotic laparoscopy for a mini-invasive releasing of both pudendal and inferior cluneal nerves, following a 4-step technique: 1. Opening of the peritoneum between the external iliac vessels and the umbilical ligament 2. Dissection of the internal iliac and pudendal arteries up to the pudendal nerve 3. Section of the sacrospinous ligament and release of the pudendal nerve 4. Section of the sacrotuberous ligament and release of the inferior cluneal nerve CONCLUSION: Previously, pudendal and inferior cluneal neuralgias have been managed with an invasive open transgluteal surgery. Here, we demonstrate the feasibility of a mini-invasive transperitoneal robotic laparoscopy, with a standardized 4-step surgical technique. VIDEO ABSTRACT.

Long-term outcomes after percutaneous cryoablation of abdominal wall endometriosis.

OBJECTIVE: To retrospectively evaluate the long-term outcomes after percutaneous cryoablation of abdominal wall endometriosis (AWE). METHOD: The Institutional Review Board approved this retrospective observational review of 40 consecutive patients, of a median age of 37 years (interquartile range [IQR] 32-40 years), presenting with a total of 52 symptomatic AWE nodules. All patients underwent cryoablation between January 2013 and May 2022 with a minimum follow-up period of 12 months. Outcomes were assessed using a visual analog scale (VAS) that measured pain, as well as by magnetic resonance imaging (MRI). The pain-free survival rates were derived using the Kaplan-Meier estimator. Adverse events were analyzed and graded using the classification system of the Cardiovascular and Interventional Radiological Society of Europe. RESULTS: The median follow-up time was 40.5 months (IQR 26.5-47.2 months). The median VAS score before cryoablation was 8 (IQR 7-9). Complete relief of symptoms was documented in 80% (32/40) of patients at 3 months after initial cryoablation and correlated with the absence of residual endometriosis nodules on MRI. The median pain-free survival rates were 89.2% [95% CI, 70.1-96.4%] at 36 months and 76.8% [95% CI, 55.3-83.8%] after 60 months. No patient or lesion characteristics were found to be prognostic of failure. No major adverse events or side effects were reported in long term. CONCLUSION: Cryoablation safely and effectively afforded long-term pain relief for patients with AWE nodules. CLINICAL RELEVANCE STATEMENT: AWE cryoablation was found to be safe and effective in the long-term. KEY POINTS: • Cryoablation is highly effective with 80% of patients experiencing complete relief of AWE symptoms after a single procedure. • Cryoablation is safe without long-term adverse events or side effects. • The median pain-free survival rates are 89.2% at 36 months and 76.8% at 60 months.

Intermittent Self-catheterization for Bladder Dysfunction After Deep Endometriosis Surgery: Duration and Factors that Might Affect the Recovery Process.

STUDY OBJECTIVE: To assess the duration needed for regaining normal bladder voiding function in patients with postoperative bladder dysfunction requiring intermittent self-catheterization after deep endometriosis surgery and identify risk factors that might affect the recovery process. DESIGN: Retrospective study based on data recorded in a large prospective database. SETTING: Endometriosis referral center. PATIENTS: From September 2018 to June 2022, 1900 patients underwent excision of deep endometriosis in our center; 61 patients were discharged with recommendation for intermittent self-catheterization and were thus included in the study. INTERVENTIONS: Intermittent self-catheterization after endometriosis surgery. MEASUREMENTS AND MAIN RESULTS: A total of 43 patients (70.5%) stopped self-catheterization during the follow-up period. Median follow-up was 25 weeks (range, 7-223 wk). Surgery was performed laparoscopically in 48 patients (78.7%) and robotically in 13 (21.3%); 47 patients (77%) had nodules involving the digestive tract, 11 (18%) had urinary tract involvement, 29 had parametrial nodules (47.5%), and 13 (21.3%) had sacral plexus involvement. The probability of bladder voiding function recovery and arrest of self-catheterization was 24.5%, 54%, 59%, 72%, and 77% at 4, 8, 12, 52, and 78 weeks, respectively. Cox's multivariate model identified preoperative bladder dysfunction as the only statistically significant independent predictor for arrest of self-catheterization (hazard ratio, 0.36; 95% confidence interval, 0.15-0.83). CONCLUSION: Patients requiring intermittent self-catheterization for bladder dysfunction after deep endometriosis excision may spontaneously recover bladder function in 77% of cases. Symptoms suggesting preoperative bladder voiding dysfunction should be reviewed before planning surgery, and patients should be informed of the higher postoperative risk of long-term bladder voiding dysfunction.

Surgical treatment of deep endometriosis: Impact on spontaneous conception.

Deep endometriosis (DE) is the most severe form of endometriosis and is commonly associated with infertility. Surgical treatment of DE appears to increase chances of spontaneous conception in appropriately selected patients wishing to conceive. Identifying, however, the exact impact of DE, and its surgical removal, on natural conception is highly challenging. The surgical approach should be favoured in symptomatic patients with pregnancy intention. Limited data from infertile patients suggest that outcomes may not differ from patients without known infertility. Complex DE surgery carries a risk of serious complications, therefore, it should be performed in centers of expertise. Such complications may, however, not have a significant negative impact on fertility outcomes, according to limited available data. Data on obstetric outcomes of spontaneous conceptions after DE surgery are too scarce. In asymptomatic, infertile patients the debate between primary surgery or Artifial Reproductive Technology is ongoing, until randomized studies report their results.

Combined Cystoscopic-Abdominal Versus Abdominal-Only Route for Complete Excision of Large Deep Endometriosis Nodules Infiltrating the Supratrigonal Area of the Bladder: A Comparative Study.

STUDY OBJECTIVE: Surgical excision of large deep endometriosis nodules infiltrating the bladder may be challenging, particularly when the nodule limits are close to the trigone and ureteral orifice. Bladder nodules have classically been approached abdominally. However, combining a cystoscopic with an abdominal approach may help to better identify the mucosal borders of the lesion to ensure complete excision without unnecessary resection of healthy bladder. This study aimed to compare classical excision of large bladder nodules by abdominal route with a combined cystoscopic-abdominal approach. DESIGN: Retrospective comparative study on data prospectively recorded in a database. Patients were managed from September 2009 to June 2022. SETTING: Two tertiary referral endometriosis centers. PATIENTS: A total of 175 patients with deep endometriosis infiltrating the bladder more than 2 cm undergoing surgical excision of bladder nodules. INTERVENTIONS: Excision of bladder nodules by either abdominal or combined cystoscopic-abdominal approaches. MEASUREMENTS AND MAIN RESULTS: A total of 141 women (80.6%) were managed by abdominal route and 34 women (19.4%) underwent a combined cystoscopic-abdominal approach. In 99.4% of patients, the approach was minimally invasive. Patients with nodules requiring the combined approach had a lower American Fertility Society revised score and endometriosis stage and less associated digestive tract nodules, but larger bladder nodules. They were less frequently associated with colorectal resection and preventive stoma. Operative time was comparable. The rate of early postoperative complications was comparable (8.8% vs 22%), as were the rates of ureteral fistula (2.2% vs 2.9%), bladder fistula (2.2% vs 0), and vesicovaginal fistula (0.7% vs 2.9%). CONCLUSION: In our opinion, the combined cystoscopic-abdominal approach is useful in patients with large bladder nodules with limits close to the trigone and ureteral orifice. These large deep bladder nodules seemed paradoxically associated to less nodules on the digestive tract, resulting in an overall comparable total operative time and complication rate.

Robotic Management of Recurrent Rectal Endometriosis After Previous Segmental Bowel Resection.

OBJECTIVE: To describe the management of recurrent bowel endometriosis after previous colorectal resection. DESIGN: Surgical video article. The local institutional board review was omitted due to the narration of surgical management. Patient consent was obtained. SETTING: A tertiary referral center. The patient first underwent segmental bowel resection for deep infiltrating endometriosis of the rectum in the ENDORE randomized controlled trial in 2012 and then received a total hysterectomy in 2018. Five years later, she presented with recurrent nodules in the rectovaginal, left parametrium, and abdominal wall after discontinuing medical suppressive treatment. INTERVENTION: Laparoscopic management using robotic assistance was employed to complete excision of the rectovaginal nodule. Disc excision was performed to remove rectal infiltration. The procedure started with rectal shaving and excision of vaginal infiltration . A traction stitch was placed over the limits of the rectal shaving area. The general surgeon placed a 28 mm circular anal stapler transanally and performed complete excision of the shaved rectal area. Anastomotic perfusion was checked with indocyanine green. A methylene blue enema test was conducted to rule out anastomotic leakage. Outcomes were favorable, with systematic self-catheterization during 5 postoperative weeks. No specific symptoms were related to the other 2 nodules, which were not removed. CONCLUSION: Rectal recurrences may occur long after colorectal resection and outside the limits of the previous surgery site. To accurately assess this risk, long-term follow-up of patients is mandatory.. Postoperative medical amenorrhea may play a role in recurrence prevention. Surgical management of recurrences may be challenging and focus on only those nodules responsible for symptoms so as to best preserve the organ's function and reduce postoperative morbidity.

Robotic Surgery for Severe Endometriosis: A Preliminary Comparative Study of Cost Estimation.

STUDY OBJECTIVE: To compare the postoperative outcomes and the overall expenses between conventional laparoscopy and robotic surgery, in a series of consecutive patients managed for only severe endometriosis in our institute. DESIGN: A cohort comparative study. SETTING: Center of Excellence in Multidisciplinary Endometriosis Care. PATIENTS: A total of 175 symptomatic patients undergoing surgery for only severe endometriosis from March 2021 to August 2022. INTERVENTIONS: We treated patients with endometriosis involving the digestive tract such as rectum, sigmoid colon, and ileocecal junction by rectal shaving, discoid resection, or segmental resection (141 surgeries) with or without bladder (23 surgeries), sacral plexus (19 surgeries), and diaphragm involvements (14 surgeries). MEASUREMENTS AND MAIN RESULTS: Postoperative outcomes were evaluated in terms of total surgical time (total surgical room occupancy time and total operating time), hospitalization period, postoperative complications, rehospitalization, and second surgical procedures. A statistically higher total surgical room occupancy (203 minutes vs 151 minutes) and operating time (150 minutes vs 105 minutes) were observed in the robotic group (p = .001). No differences in terms of mean hospital stay (p = .06), postoperative complications (p = .91), rehospitalization (p = .48), and secondary surgical treatment (p = .78) were identified. Concerning the cost analysis only for disposable supply, the cost of colorectal resection was totaled at 2604 euros for the laparoscopic conventional approach vs 2957 euros for the robotic approach (+352.6 euros, +14%). The cost of rectal disc excision was 1527 euros for the laparoscopic conventional approach vs 1905.85 euros (+378 euros, +25%). CONCLUSIONS: Our study confirms the feasibility of the robotic approach for the treatment of severe endometriosis, with however a higher cost of robotic approach. Next studies should identify specific indications for robotic surgery, where technical advantages provided by the technology are followed by objective improvement of patients' outcomes.

Combined Robotic Transanal Transection Single-Stapled Technique in Ultralow Rectal Endometriosis Involvement Associated With Parametrial and Vaginal Infiltration.

OBJECTIVE: To describe a combined robotic and transanal technique used to treat ultralow rectal endometriosis in a 36-year-old patient with multiple pelvic compartments, which was responsible for infertility, dyspareunia, left sciatic pain, and severe dyschezia. DESIGN: Surgical video article. SETTING: The achievement of a perfect bowel anastomosis in patients with low rectal endometriosis could be challenging owing to technical and anatomic limitations [1]. By allowing a right angle rectotomy with a single-stapled anastomosis, the transanal transection single-stapled technique overcomes these technical difficulties ensuring a good-quality anastomosis with an easier correction of postoperative anastomotic leakage when it occurs [2,3]. INTERVENTIONS: The surgery starts by splitting the nodule in 3 components according to different anatomic structures involved (parametrium, vagina, and rectum). Parametrial and vaginal fragments are excised as previously described (Supplemental Videos 1) [4]. The rectal involvement is approached following several steps: isolation and cut of inferior mesenteric vessels (inferior mesenteric artery and inferior mesenteric vein) and left colic artery to obtain a proper colon mobilization; transanal rectotomy immediately below the lower limit of the nodule; extraction of the specimen through the anus (Supplemental Videos 2); proximal bowel segment transection 1 cm above the upper limit of the nodule; introduction of circular stapler anvil into the sigmoid colon; placement of 2 purse string to secure the anvil and at distal rectal cuff, respectively; connection of the anvil to the shoulder of circular stapler; stapler closing and firing with coloanal anastomosis formation; stapled line reinforcement by stitching; and integrity anastomosis test (Supplemental Videos 3). No preventive diverting stoma was performed in accordance with our policy [5]. CONCLUSIONS: Although no data are yet available in patients with endometriosis, the use of transanal transection single-stapled technique may be an interesting approach in patients with very low rectal endometriosis involvement.

Investigating the medical journey of endometriosis-affected women: Results from a cross-sectional web-based survey (EndoVie) on 1,557 French women.

OBJECTIVE: To investigate the medical journey and the quality of life of French endometriosis-affected women, from the onset of the symptoms to the therapeutic management. STUDY DESIGN: Between January 15th 2020 and February 3rd 2020, a prospective cross-sectional web-based survey was conducted among women diagnosed with endometriosis. The questionnaire included 52 questions distributed in five sections (screening, sociodemographic characteristics, impacts on quality of life, SF36 questionnaire, management of endometriosis and proposals for care improvement). RESULTS: One thousand five hundred fifty-seven endometriosis-affected women aged of 42±12.8 years answered the questionnaire. On average, 7 years elapsed between the first symptoms (at 23.8 ± 10.2 years) and the diagnosis (31.0 ± 8.9 years). The mean number of symptoms was 4.6 ± 2.3, with 82 % of women experiencing pain scores between 7 and 10/10. Following diagnosis, 66 % women received a medical treatment, mostly hormonal treatments (45 %), with a significant decrease in pain intensity (VAS scores after treatment = 4.9 ± 2.7, p < 0.001). Most women (62 %) had already been operated, among whom 22 % by laparotomy. Finally, patients reported numerous impacts on their daily lives, particularly on the sexual, psychological, and physical fields. The overall mean score of quality of life was 4.3 ± 2.6 /10. CONCLUSION: This large prospective web-based survey underlines that the journey of women with endometriosis is long and difficult until diagnosis and efficient treatment. It emphasizes the urgent need to reduce the diagnostic delay and thereby the burden of endometriosis on women's lives. Moreover, the creation of referral multidisciplinary centers appears to be crucial to improve the management of the disease.

Evaluation of the efficacy of sacral neuromodulation in the treatment of voiding dysfunction after endometriosis surgery.

Pelvic surgery for endometriosis is associated with a risk of bladder and digestive sequelae. Sacral neuromodulation (SNM) has been shown to be effective in the treatment of overactive bladder (OAB) and voiding dysfunction (VD). This study aimed to evaluate the efficacy of sacral neuromodulation (SNM) in treating voiding dysfunction (VD) following endometriosis surgery. A retrospective analysis was conducted on data from women who underwent SNM testing for persistent VD after endometriosis surgery. The study included 21 patients from a French tertiary referral center. Patient characteristics, lower urinary tract symptoms, urodynamic findings, SNM procedures, and outcomes were assessed. The primary outcome was the success of SNM treatment for VD. After a median follow-up of 55 months, 60% of patients achieved successful outcomes, with significant improvements of VD and quality of life. Moreover, more than half of patients who required clean intermittent self-catheterization (CISC) before SNM were able to wean off CISC. Complications such as infections and paraesthesia were observed, but overall, SNM was found to be effective and well tolerated. Age and the interval between endometriosis surgery and SNM testing were associated with treatment success. This study adds to the limited existing literature on SNM for VD after endometriosis surgery and suggests that SNM can be a valuable therapeutic option for these patients. Further research is needed to identify predictive factors and mechanisms underlying the effectiveness of SNM in this context. MRI-compatible and rechargeable devices, has improved the feasibility of SNM for these patients. In conclusion, SNM offers promise as a treatment option for persistent VD after endometriosis surgery, warranting further investigation. LEVEL OF EVIDENCE: 4.

Robotic-assisted versus conventional laparoscopic approach in patients with large rectal endometriotic nodule: the evaluation of safety and complications.

AIM: The aim was to compare postoperative complications in patients undergoing the excision of a rectal endometriotic nodule over 3 cm by a robotic-assisted versus a conventional laparoscopic approach. METHODS: We conducted a retrospective cohort study evaluating prospectively collected data. The main interventions included rectal shaving, disc excision or colorectal resection. All the surgeries were performed in one endometriosis reference institute. To evaluate factors significantly associated with the risk of anastomosis leakage or fistula and bladder atony, we conducted a multivariate logistic regression model. RESULTS: A total of 548 patients with rectal endometriotic nodule over 3 cm in diameter (#ENZIAN C3) were included in the final analysis. The demography and clinical characteristics of women managed by the robotic-assisted (n = 97) approach were similar to those of patients who underwent conventional laparoscopy (n = 451). The multivariate logistic regression demonstrated that the surgical approach (robotic-assisted vs. laparoscopic) was not associated with the rate of anastomosis leakage or fistula (adjusted odds ratio [aOR] 1.2, 95% confidence interval [CI] 0.3-4.0) and bladder dysfunction (aOR 0.5, 95% CI 0.1-1.8). A rectal nodule located lower than 6 cm from the anal verge was significantly associated with anastomosis leakage (aOR 4.1, 95% CI 1.4-10.8) and bladder atony (aOR 4.3, 95% CI 1.5-12.3). Anastomosis leakage was also associated with smoking (aOR 3.2, 95% CI 1.4-7.4), significant vaginal infiltration (aOR 2.7, 95% CI 1.2-6.7) and excision of nodules involving sacral roots (aOR 5.6, 95% CI 1.7-15.5). CONCLUSION: The robotic-assisted approach was not associated with increased risk of main postoperative complications compared to conventional laparoscopy for the treatment of large rectal endometriotic nodules.

Surgical Management of Ovarian Endometrioma: Impact on Ovarian Reserve Parameters and Reproductive Outcomes.

Ovarian endometriomas have a negative impact on a patient's reproductive potential and are likely to cause a reduction in ovarian reserve. The most commonly employed ovarian reserve parameters are anti-Müllerian hormone (AMH) and antral follicular count (AFC). Surgical management options of endometrioma include cystectomy, ablative methods, ethanol sclerotherapy and combined techniques. The optimal surgical approach remains a matter of debate. Our review aimed to summarize the literature on the impact of surgical management of endometrioma on AMH, AFC and fertility outcomes. Cystectomy may reduce recurrence rates and increase chances of spontaneous conception. However, a postoperative reduction in AMH is to be anticipated, despite there being evidence of recovery during follow-up. The reduction in ovarian reserve is likely multi-factorial. Cystectomy does not appear to significantly reduce, and may even increase, AFC. Ablative methods achieve an ovarian-tissue-sparing effect, and improved ovarian reserve, compared to cystectomy, has been demonstrated. A single study reported on AMH and AFC post sclerotherapy, and both were significantly reduced. AMH levels may be useful in predicting the chances of conception postoperatively. None of the aforementioned approaches has a clearly demonstrated superiority in terms of overall chances of conception. Surgical management of endometrioma may, overall, improve the probability of pregnancy. Evidence on its value before medically assisted reproduction (MAR) is conflicting; however, a combination of surgery followed by MAR may achieve the optimal fertility outcome. In view of the complexity of available evidence, individualization of care, combined with optimal surgical technique, is highly recommended.

Pain Reduction With an Immersive Digital Therapeutic in Women Living With Endometriosis-Related Pelvic Pain: At-Home Self-Administered Randomized Controlled Trial.

BACKGROUND: The management of chronic pelvic pain in women with endometriosis is complex and includes the long-term use of opioids. Patients not fully responsive to drugs or ineligible for surgical treatments need efficient alternatives to improve their quality of life and avoid long-term sequelae. OBJECTIVE: This randomized controlled trial aimed to assess the effects of repeated at-home administrations of a 20-minute virtual reality (VR) solution (Endocare) compared with a sham condition on pain in women experiencing pelvic pain due to endometriosis. METHODS: Patients were instructed to use the VR headsets twice daily for at least 2 days and for up to 5 days starting on their first day of painful periods. Pain perception was measured using a numerical scale (0-10) before and 60, 120, and 180 minutes after each treatment administration. General pain, stress, fatigue, medication intake, and quality of life were reported daily by patients. RESULTS: A total of 102 patients with endometriosis were included in the final analysis (Endocare group: n=51, 50%; sham group: n=51, 50%). The mean age was 32.88 years (SD 6.96) and the mean pain intensity before treatment was 6.53 (SD 1.74) and 6.22 (SD 1.69) for the Endocare group and the sham control group, respectively (P=.48). Pain intensity decreased in both groups from day 1 to day 5 along with a decrease in medication use. Maximum pain intensity reduction of 51.58% (SD 35.33) occurred at day 2, 120 minutes after treatment for the Endocare group and of 27.37% (SD 27.23) at day 3, 180 minutes after treatment for the control group. Endocare was significantly superior to the sham on day 1 (120 minutes, P=.04; 180 minutes, P=.001), day 2 (0 minutes, P=.02; 60, 120, and 180 minutes, all P<.001), and day 3 (60 minutes, P=.01; 120 minutes, P=.005; 180 minutes, P=.001). Similarly, the mean perceived pain relief was significantly higher with Endocare on day 1 (120 and 180 minutes P=.004 and P=.001, respectively) and day 2 (60, 120, and 180 minutes P=.003, P=.004, and P=.007, respectively) compared to the control. No adverse event was reported. CONCLUSIONS: This study confirmed the effectiveness and safety of self-repeated administrations of a VR immersive treatment used at home while reducing overall pain medication intake in women diagnosed with endometriosis experiencing moderate-to-severe pelvic pain.

Robotic management of isolated endometriosis of sciatic nerve: a reproducible approach that can guide through the labyrinth of pelvic neuroanatomy.

OBJECTIVE: To present the robotic, standardized, and reproducible surgical technique we routinely use in our center to manage isolated endometriosis of the sciatic nerve. DESIGN: Surgical video article. SETTING: Tertiary referral center. PATIENT: A 36-year-old woman suffering from left-sided sciatica pain was diagnosed with an isolated endometriotic nodule of the left sciatic nerve at preoperative assessment. The patient included in this video gave consent for publication of the video and posting of the video online, including on social media, the journal website, scientific literature websites (such as PubMed, ScienceDirect, and Scopus), and other applicable sites. INTERVENTION(S): Complete removal of the isolated endometriotic nodule of the sciatic nerve may be performed through a stepwise robotic approach. The surgery starts laterally with the opening of the iliolumbar space between the external iliac vessels and the psoas muscle, as well as the identification of the genitofemoral and obturator nerves. The lumbosacral trunk and emergence of the sciatic nerve were then identified medially and caudally to the obturator nerve. The surgery moves medially with the anterograde dissection of both the internal iliac artery and vein, which allows a safe approach to the posterior and medial limits of the nodule. Ligation of branches of internal iliac vessels directed toward the nodule may be necessary during this step. Isolation and ligation of obturator vessels are frequently required to obtain a bloodless dissection of the lateral limit of the nodule from the lateral pelvic wall. The complete removal of the nodule was then achieved using an alternating approach to all limits of the nodule previously identified, with subsequent release of the sciatic nerve. MAIN OUTCOME MEASURE(S): Description of the relevant pelvic neuroanatomy and the evaluation of robotic routes in the field of pelvic neurosurgery. RESULT(S): The use of standardized techniques together with the advantages of a robotic route can make the radical excision of isolated endometriosis of the sciatic nerve reproducible, feasible, and safe. CONCLUSION(S): Because of the complexity of neuroanatomy and the risk of severe complications, this surgery remains challenging, and patients affected by deep infiltrating endometriosis involving retroperitoneal neural structures should be referred to multidisciplinary management in expert centers.

Multicenter External Validation of the Deep Pelvic Endometriosis Index Magnetic Resonance Imaging Score.

Importance: Preoperative mapping of deep pelvic endometriosis (DPE) is crucial as surgery can be complex and the quality of preoperative information is key. Objective: To evaluate the Deep Pelvic Endometriosis Index (dPEI) magnetic resonance imaging (MRI) score in a multicenter cohort. Design, Setting, and Participants: In this cohort study, the surgical databases of 7 French referral centers were retrospectively queried for women who underwent surgery and preoperative MRI for DPE between January 1, 2019, and December 31, 2020. Data were analyzed in October 2022. Intervention: Magnetic resonance imaging scans were reviewed using a dedicated lexicon and classified according to the dPEI score. Main outcomes and measures: Operating time, hospital stay, Clavien-Dindo-graded postoperative complications, and presence of de novo voiding dysfunction. Results: The final cohort consisted of 605 women (mean age, 33.3; 95% CI, 32.7-33.8 years). A mild dPEI score was reported in 61.2% (370) of the women, moderate in 25.8% (156), and severe in 13.1% (79). Central endometriosis was described in 93.2% (564) of the women and lateral endometriosis in 31.2% (189). Lateral endometriosis was more frequent in severe (98.7%) vs moderate (48.7%) disease and in moderate vs mild (6.7%) disease according to the dPEI (P < .001). Median operating time (211 minutes) and hospital stay (6 days) were longer in severe DPE than in moderate DPE (operating time, 150 minutes; hospital stay 4 days; P < .001), and in moderate than in mild DPE (operating time; 110 minutes; hospital stay, 3 days; P < .001). Patients with severe disease were 3.6 times more likely to experience severe complications than patients with mild or moderate disease (odds ratio [OR], 3.6; 95% CI, 1.4-8.9; P = .004). They were also more likely to experience postoperative voiding dysfunction (OR, 3.5; 95% CI, 1.6-7.6; P = .001). Interobserver agreement between senior and junior readers was good (κ = 0.76; 95% CI, 0.65-0.86). Conclusions and Relevance: The findings of this study suggest the ability of the dPEI to predict operating time, hospital stay, postoperative complications, and de novo postoperative voiding dysfunction in a multicenter cohort. The dPEI may help clinicians to better anticipate the extent of DPE and improve clinical management and patient counseling.

Diagnosis of Endometriosis by Transvaginal Ultrasound: An Online Survey of Gynecologists Practising in Greece.

Accurate diagnosis and assessment of endometriosis by transvaginal ultrasound scan (TVS) can be challenging. We performed an online survey of specialist gynecologists who perform TVS on a regular basis regarding their views as well as clinical experience on the use of TVS in the diagnosis of endometrioma and deep endometriosis (DE). We collected 64 responses. Sixty-one participants (95.31%) answered that they can confidently diagnose endometrioma by TVS "always" or "most of the time". With the exception of DE of the recto-vaginal septum/posterior vaginal vault, for all other DE locations, more than 50% of participants felt that they can "rarely" or "never" diagnose it by TVS in their own clinical practice. Forty-two participants (65.6%) stated that additional, specialized training is required for the diagnosis of endometrioma. When asked about a diagnosis of DE, 58 participants (90.6%) felt that the same is required.
