Role of V-Y flap reconstruction in vulvar cancer patients: multicenter retrospective study.

OBJECTIVE: To assess if the use of a V-Y reconstructive flap after excisional radical surgery positively influences the surgical outcomes in patients with vulvar cancer. METHODS: This was a multicenter, retrospective, controlled study. Surgical outcomes and complication rates of women with invasive vulvar cancer who underwent radical surgery and vulvar reconstruction and those who underwent radical surgery without the reconstruction step were compared. Only patients who underwent bilateral or unilateral V-Y advancement fascio-cutaneous flaps were included in the reconstruction group. Univariate and multivariate logistic regression models were used to analyze predicting variables for their association with complication rates. RESULTS: Overall, 361 patients were included: 190 (52%) underwent the reconstructive step after the excisional radical procedure and were compared with 171 (47.4%) who did not undergo the reconstructive step. At multivariate analysis, body mass index >30 kg/m2 (odds ratio (OR) 3.36, p=0.007) and diabetes (OR 2.62, p<0.022) were independently correlated with wound infection. Moreover, increasing age (OR 1.52, p=0.009), body mass index >30 kg/m2 (OR 3.21, p=0.002,) and International Federation of Gynecology and Obstetrics (FIGO) stages III-IV (OR 2.25, p=0.017) were independent predictors of wound dehiscence. A significant reduction in the incidence of postoperative wound complications among patients who underwent V-Y reconstructive flaps was demonstrated. This was correlated more significantly in women with lesions >4 cm. CONCLUSIONS: The adoption of V-Y flaps in vulvar surgery was correlated with reduced surgical related complications, particularly in vulnerable patients involving large surgical defects following excisional radical procedures.

SENECA study: staging endometrial cancer based on molecular classification.

OBJECTIVE: Management of endometrial cancer is advancing, with accurate staging crucial for guiding treatment decisions. Understanding sentinel lymph node (SLN) involvement rates across molecular subgroups is essential. To evaluate SLN involvement in early-stage (International Federation of Gynecology and Obstetrics 2009 I-II) endometrial cancer, considering molecular subtypes and new European Society of Gynaecological Oncology (ESGO) risk classification. METHODS: The SENECA study retrospectively reviewed data from 2139 women with stage I-II endometrial cancer across 66 centers in 16 countries. Patients underwent surgery with SLN assessment following ESGO guidelines between January 2021 and December 2022. Molecular analysis was performed on pre-operative biopsies or hysterectomy specimens. RESULTS: Among the 2139 patients, the molecular subgroups were as follows: 272 (12.7%) p53 abnormal (p53abn, 1191 (55.7%) non-specific molecular profile (NSMP), 581 (27.2%) mismatch repair deficient (MMRd), 95 (4.4%) POLE mutated (POLE-mut). Tracer diffusion was detected in, at least one side, in 97.2% of the cases; with a bilateral diffusion observed in 82.7% of the cases. By ultrastaging (90.7% of the cases) or one-step nucleic acid amplification (198 (9.3%) of the cases), 205 patients were identified with affected sentinel lymph nodes, representing 9.6% of the sample. Of these, 139 (67.8%) had low-volume metastases (including micrometastases, 42.9%; and isolated tumor cells, 24.9%) while 66 (32.2%) had macrometastases. Significant differences in SLN involvement were observed between molecular subtypes, with p53abn and MMRd groups having the highest rates (12.50% and 12.40%, respectively) compared with NSMP (7.80%) and POLE-mut (6.30%), (p=0.004); (p53abn, OR=1.69 (95% CI 1.11 to 2.56), p=0.014; MMRd, OR=1.67 (95% CI 1.21 to 2.31), p=0.002). Differences were also noted among ESGO risk groups (2.84% for low-risk patients, 6.62% for intermediate-risk patients, 21.63% for high-intermediate risk patients, and 22.51% for high-risk patients; p<0.001). CONCLUSIONS: Our study reveals significant differences in SLN involvement among patients with early-stage endometrial cancer based on molecular subtypes. This underscores the importance of considering molecular characteristics for accurate staging and optimal management decisions.

Total laparoscopic segmental resection with transanal natural orifice specimen extraction for treatment of colorectal endometriosis: Descriptive analysis from the TrEnd study database.

OBJECTIVE: To report our 3-year institutional experience of total laparoscopic (TL) segmental sigmoid colon/rectal resection for treatment of bowel endometriosis (BE). DESIGN: The TrEnd trial is a single-institutional retrospective/prospective study conducted with the aim of systematically collecting data from consecutive patients undergoing segmental colorectal resection for BE. This paper reports the outcomes of patients undergoing intracorporeal anastomosis and transanal natural orifice specimen extraction (NOSE) from this database. Primary endpoints were to evaluate the safety and efficacy of this approach in terms of: complications, conversion to conventional technique/open surgery, endometriosis-free bowel resection margins, recurrence. Secondary endpoints were to assess: intraoperative blood loss, operating time, gastrointestinal function recovery, duration of hospital stay, reproductive outcomes. SETTING: Malzoni Research Hospital, Avellino, Italy. PARTICIPANTS: Only patients undergoing TL colorectal resection with transanal NOSE were included in the present analysis. Patients were considered non-eligible if they had received concomitant hysterectomy and/or transvaginal NOSE. INTERVENTIONS: Results presented here are descriptive. RESULTS: Eighty-one patients were included in the present analysis. Post-operative severe complications occurred in 3.7%. No cases of intraoperative complications or conversion to conventional technique/open surgery occurred. Final pathology showed endometriosis-free resection margins in all colorectal specimens. After a median follow-up of 21 months, all patients were free from BE. Median blood loss was 20 mL. Median length of surgery was 160 minutes. Median hospital length of stay was 3 days. All patients achieved the first passage of flatus on post-operative day 1. Median time to first defecation was 4 days. Twenty-six patients attempted to conceive. Nine of them achieved a pregnancy and 2 gave birth to a healthy child. CONCLUSION: This study represents the main experience on TL segmental colorectal resection for BE treatment. The observed optimal outcomes seem to recommend further studies to assess safety and efficacy of said surgical technique in women with BE. Clinical trial registry name: ClinicalTrials.gov.

Non-Invasive Imaging Techniques for Diagnosis of Pelvic Deep Endometriosis and Endometriosis Classification Systems: An International Consensus Statement.

The International Society of Ultrasound in Obstetrics and Gynecology (ISUOG) and International Deep Endometriosis Analysis (IDEA) group, the European Endometriosis League (EEL), the European Society for Gynaecological Endoscopy (ESGE), the European Society of Human Reproduction and Embryology (ESHRE), the International Society for Gynecologic Endoscopy (ISGE), the American Association of Gynecologic Laparoscopists (AAGL) and the European Society of Urogenital Radiology (ESUR) elected an international, multidisciplinary panel of gynecological surgeons, sonographers and radiologists, including a steering committee, which searched the literature for relevant articles in order to review the literature and provide evidence-based and clinically relevant statements on the use of imaging techniques for non-invasive diagnosis and classification of pelvic deep endometriosis. Preliminary statements were drafted based on review of the relevant literature. Following two rounds of revisions and voting orchestrated by chairs of the participating societies, consensus statements were finalized. A final version of the document was then resubmitted to the society chairs for approval. Twenty statements were drafted, of which 14 reached strong and three moderate agreement after the first voting round. The remaining three statements were discussed by all members of the steering committee and society chairs and rephrased, followed by an additional round of voting. At the conclusion of the process, 14 statements had strong and five statements moderate agreement, with one statement left in equipoise. This consensus work aims to guide clinicians involved in treating women with suspected endometriosis during patient assessment, counseling and planning of surgical treatment strategies.

Ten-year outcomes following laparoscopic and open abdominal radical hysterectomy for "low-risk" early-stage cervical cancer: A propensity-score based analysis.

OBJECTIVE: Accumulating evidence suggested the detrimental effects of adopting minimally invasive surgery in the management of early-stage cervical cancer. However, long-term evidence on the role of minimally invasive radical hysterectomy in "low-risk" patients exists. METHODS: This is multi-institutional retrospective study comparing minimally invasive and open radical hysterectomy in low-risk early-stage cervical cancer patients. A propensity-score matching algorithm (1:2) was used to allocate patients into the study groups. Kaplan-Meir model was used to estimate 10-year progression-free and overall survival. RESULTS: Charts of 224 "low-risk" patients were retrieved. Overall, 50 patients undergoing radical hysterectomy were matched with 100 patients undergoing open radical hysterectomy. Minimally invasive radical hysterectomy was associated with a longer median operative time (224 (range, 100-310) vs. 184 (range, 150-240) minutes; p < 0.001), lower estimated blood loss (10 (10-100) vs. 200 (100-1000) ml, p < 0.001), and shorter length of hospital stay (3.8 (3-6) vs. 5.1 (4-12); p < 0.001). Surgical approach did not influence the risk of having intra-operative (4% vs. 1%; p = 0.257) and 90-day severe (grade 3+) postoperative complication rates (4% vs. 8%; p = 0.497). Ten-year disease-free survival was similar between groups (94% vs. 95%; p = 0.812; HR:1.195; 95%CI:0.275, 5.18). Ten-year overall survival was similar between groups (98% vs. 96%; p = 0.995; HR:0.994; 95%CI:0.182, 5.424). CONCLUSIONS: Our study appears to support emerging evidence suggesting that, for low-risk patients, laparoscopic radical hysterectomy does not result in worse 10-year outcomes compared to the open approach. However, further research is needed and open abdominal radical hysterectomy remains the standard treatment for cervical cancer patients.

Laparoscopic Double Discoid Colorectal Resection for the Treatment of Two Distinct Deep Endometriotic Nodules.

OBJECTIVE: To show the surgical steps used to perform a laparoscopic double discoid colorectal resection for the excision of 2 distinct deep endometriotic nodules (DENs). DESIGN: Stepwise demonstration of the technique with narrated video footage. SETTING: To date there is agreement that discoid resection should be the first choice procedure in patients eligible for surgical treatment with rectal, unifocal DENs measuring ≤ 3 cm [1-3]. For surgical management of lesions of the sigmoid colon, current international guidelines suggest to perform segmental resections [3]. Data on surgical treatment of multiple colorectal DENs separated by a great distance from each other are very limited, mostly owing to the rarity of such a diagnosis. In particular, there is paucity of data concerning the efficacy and safety of a double discoid resection for surgical management of distinct DENs found in the sigmoid colon and rectum [4]. In a context of multiple colorectal DENs, the decision-making process with respect to a double discoid excision must take into consideration both the distance between the 2 nodules and the nodules' distance from anal verge. When technically feasible, such organ-sparing surgery allows preserving the healthy bowel interposed between the endometriotic lesions, seeming to offer advantages in terms of quicker return of bowel function and better rectal functional outcomes than segmental colorectal resection. INTERVENTIONS: The patient was a 36-year-old woman experiencing drug treatment failure and presenting with refractory constipation, dyschezia, dysmenorrhea, dyspareunia, cyclical abdominal bloating, and chronic pelvic pain. Preoperative ultrasonography revealed the presence of an endometriotic nodule of 19 × 6 × 16 mm deeply infiltrating the tunica muscularis of the sigmoid colon. A second DEN was found at the level of the rectum, the latter measuring 19 × 5 × 12 mm and having a distance of 9 cm from the anal verge. Both the intestinal lesions resulted to have a circumferential extent of 30%. The distance between the 2 nodules was 15 cm. A 3-dimensional laparoscopy was performed. Sigmoid colon and rectal mobilization were performed according to our standardized technique [5-7]. A 31-mm circular stapler was used to excise first the nodule of the sigmoid colon. The stapler, in its closed position, was gently introduced into the rectum via the anus and then progressively advanced inside the large bowel up to the level of the sigmoid nodule. After correct positioning, the stapler was completely opened and the nodule was imbricate between the anvil and staple housing of the stapler. Then, the stapler was closed and fired. The procedure was repeated using a second 31 mm circular stapler to resect the rectal endometriotic nodule. The overall operative time was 90 minutes. The estimated blood loss was 5 mL. Neither intra- nor postoperative complications occurred. The patient was discharged 3 days after surgery. The sigmoid colon and rectal endometriotic nodules measured, respectively, 20 × 6 × 15 mm and 20 × 5 × 12 mm on fresh unfixed specimens. Both nodules were found to have endometriosis-free surgical margins on definitive pathology. CONCLUSIONS: The operative technique displayed in this video may contribute to the standardization of a procedure, which could be included among the options available in the surgical armamentarium, to be used in selected cases of multiple colorectal DENs each having 3 cm or less in diameter. Surgeon experience and an adequate preoperative evaluation are of utmost importance to plan the operative strategy and have the best chance of surgical success.

Evaluation of Peri-Operative Management in Women with Deep Endometriosis Who are Candidates for Bowel Surgery: A Survey from the Italian Society of Gynecologic Endoscopy.

STUDY OBJECTIVE: There is great consensus that the implementation of the enhanced recovery after surgery (ERAS) approach is beneficial for surgical patients, but there is a paucity of data concerning its application in women with deep endometriosis (DE) who are candidates for bowel surgery. The survey described herein was aimed at gathering detailed information on perioperative management of DE patients who were undergoing sigmoid/rectal (discoid or segmental) resection within the Italian Society of Gynecologic Endoscopy (SEGI) group. DESIGN: Baseline survey. SETTING: National survey conducted within the main Italian cooperative group in minimally invasive gynecologic surgery (SEGI). PATIENTS: The study did not involve patients. INTERVENTIONS: A 63-item questionnaire covering ERAS items for gynecologic/elective colorectal surgery was sent to SEGI centers. Only questionnaires from centers that reported performing ≥10 sigmoid/rectal resections per year were considered for this analysis. MEASUREMENTS AND MAIN RESULTS: Thirty-three of 38 (86.8%) of the questionnaires were analyzed. The rates of concordance with the ERAS guidelines were 40.4%, 64.4%, and 62.6% for preoperative, intraoperative, and postoperative items, respectively. The proportion of overall agreement was 56.6%. Preoperative diet, fasting and bowel preparation, correction of anemia, avoidance of peritoneal drains, postoperative feeding, and early mobilization were the most controversial items. Comparative analysis revealed that the referred rates of complete disease removal and conversion to open surgery were significantly different depending on case volume (p = .044 and p = .003, respectively) and gynecologist's/surgeon's experience (p = .042 and p = .022, respectively), with higher chances of obtaining a complete laparoscopic/robotic excision of endometriosis in centers that reported ≥30 DE surgeries performed per year and/or ≥90% of bowel resections performed by a gynecologist/general surgeon specifically dedicated to DE management. In contrast, the rates of concordance with the ERAS guidelines were not significantly different according to case volume (p = .081) or gynecologist's/surgeon's experience (p = .294). CONCLUSION: This is the first study on DE conducted on a national scale. The current survey results revealed suboptimal compliance with the ERAS recommendations and underline the need to improve the quality of perioperative care in DE patients undergoing sigmoid/rectal resection. This study is a first step toward building a consistent, structured reporting platform for the SEGI units and facilitating wide implementation and standardization of the ERAS protocol for DE patients in Italy.

Preoperative Ultrasound Scoring of Endometriosis by AAGL 2021 Endometriosis Classification Is Concordant with Laparoscopic Surgical Findings and Distinguishes Early from Advanced Stages.

STUDY OBJECTIVE: To compare the accuracy of preoperative ultrasound (US) in predicting the laparoscopically defined 2021 American Association of Gynecologic Laparoscopists (AAGL) Endometriosis Staging. DESIGN: Retrospective multicenter study of patients treated at 3 specialized endometriosis centers. SETTING: Three specialized endometriosis surgical centers in São Paulo (Brazil), Barcelona (Spain), and Avellino (Italy) participated. PATIENTS: A total of 878 patients aged 15 to 45 years with no history of pelvic malignancy underwent laparoscopic (LPS) treatment for suspected endometriosis. INTERVENTIONS: Retrospective review of preoperative transvaginal and transabdominal US (index test) assessed for endometriosis at all sites used in the 2021 AAGL Endometriosis Classification and classified patients into AAGL-US stages 1 to 4. Results were compared with reference-standard LPS (AAGL-LPS) staging. MEASUREMENTS AND MAIN RESULTS: The AAGL-US and AAGL-LPS stage were concordant in 586 cases (66.7%) (weighted kappa [WK] 0.759; intraclass correlation = 0.906), with the highest agreement observed in patients with no endometriosis (n = 70, 75.3% concordance), AAGL-LPS stage 1 (104, 50.7%) and stage 4 disease (358, 88.2%). Endometriosis was most accurately diagnosed in the rectum/sigmoid colon (WK 0.862), bladder (WK 0.911), and ovaries (WK 0.835/0.795 for right/left, respectively) and least accurately diagnosed at superficial peritoneal (WK 0.442), tubal (WK 0.391/0.363 for right/left, respectively), and retrocervical/uterosacral ligament (WK 0.656) sites. CONCLUSION: Sonographic estimation of the 2021 AAGL Endometriosis Staging is greatest in AAGL-LPS stages 1 and 4 and among patients with no endometriosis. US best identifies endometriosis of the ovaries, bladder, and bowel but is more limited for the tubes and superficial peritoneum.

Predictive Value of Ultrasound Imaging for Diagnosis and Surgery of Deep Endometriosis: A Systematic Review.

OBJECTIVE: To calculate the predictive value and thus the clinical usefulness of transvaginal ultrasound (US) imaging for the management of deep endometriosis, knowing that the positive predictive value (PPV) varies with the prevalence and probably with the volume and location of the disease. DATA SOURCES: After registration on PROSPERO (CRD42022366323), PubMed was searched for all reports describing the diagnostic accuracy of US imaging for deep endometriosis published between January 1, 2000, and October 20, 2022. METHODS OF STUDY SELECTION: The 536 articles on "endometriosis AND US And diagnosis" were hand searched, and 30 reports describing sensitivity and specificity of deep endometriosis were found. Besides sensitivity and specificity, the prevalence, localization, and size of deep endometriosis lesions were collected. TABULATION, INTEGRATION, AND RESULTS: Prevalences of deep endometriosis were reported only twice as 12% and 32% by ultrasonographers. In women undergoing surgery, prevalences vary between 40% and 100% because of the variable inclusion criteria. Specificity is higher than sensitivity for all locations: rectovaginal (97% [86-100] vs 74% [31-95], p = .0002), rectosigmoid (97% [63-100] vs 88% [37-97], p = .0082), vesicouterine (100% [97-100] vs 63% [22-100], p = .0021), and uterosacrals (91% [77-99] vs 68% [18-83], p = .0005). Notwithstanding improved equipment, accuracy did not vary over the last 20 years. Sensitivities or specificities have not been stratified by the size of the lesion, and thus, the lower detection limits are not known. In the absence of blinding, the usefulness for surgery could not be established. CONCLUSION: The reported sensitivities and specificities of transvaginal US are not only those of imaging but include symptoms and clinical examinations. In referral centers, the reported PPVs are high (94%-100%) given that prevalences are >10% and specificities are >95%. However, the extrapolation of the clinical use before surgical interventions should be considered with care, given that PPVs for smaller lesions and the lower detection limit are unknown and surgeons were not blinded to US results.

Surgical Outcomes and Complications of Laparoscopic Hysterectomy for Endometriosis: A Multicentric Cohort Study.

STUDY OBJECTIVE: To investigate the postoperative morbidity of laparoscopic hysterectomy (LH) for endometriosis/adenomyosis in terms of operative outcomes and complications. DESIGN: Retrospective multicentric cohort study. SETTING: Eight European minimally invasive referral centers. PATIENTS: Data from 995 patients with pathologically confirmed endometriosis and/or adenomyosis who underwent LH without concomitant urological and/or gastroenterological procedures from January 2010 to December 2020. INTERVENTIONS: Total LH. MEASUREMENTS AND MAIN RESULTS: Demographic patients' characteristics, surgical outcomes, and intraoperative and postoperative complications were evaluated. We considered major postoperative surgical-related complications, any grade 2 or more events (Clavien-Dindo score) that occurred within 30 days from surgery. Univariate analysis and multivariable models fit with logistic regression were used to estimate the adjusted odds ratio (OR) and corresponding 95% confidence interval (CI) for major complications. Median age at surgery was 44 years (28-54), and about half of them (505, 50.7%) were on medical treatment (estro-progestins, progestin, or Gonadotropin hormone-releasing hormone-analogues) at the time of surgery. In association with LH, posterior adhesiolysis was performed in 387 (38.9%) cases and deep nodule resection in 302 (30.0%). Intraoperative complications occurred in 3% of the patients, and major postoperative complications were registered in 93 (9.3%). The multivariable analysis showed an inverse correlation between the occurrence of Clavien-Dindo >2 complications and age (OR 0.94, 95% CI 0.90-0.99), while previous surgery for endometriosis (OR 1.62, 95% CI 1.01-2.60) and intraoperative complications (OR 6.49, 95% CI 2.65-16.87) were found as predictors of major events. Medical treatment at the time of surgery has emerged as a protective factor (OR 0.50, 95% CI 0.31-0.81). CONCLUSION: LH for endometriosis/adenomyosis is associated with non-negligible morbidity. Knowing the factors associated with higher risks of complications might be used for risk stratification and could help clinicians during preoperative counseling. The administration of estro-progestin or progesterone preoperatively might reduce the risks of postoperative complications following surgery.

Comparison Between Sonography-Based and Surgical Evaluation of Endometriotic Lesions Using the #Enzian Classification - A Retrospective Data Analysis.

PURPOSE: To compare the location and sizes of deep endometriosis (DE) lesions evaluated by preoperative transvaginal sonography (TVS) in different #Enzian compartments with intraoperatively assessed DE location and size. MATERIALS AND METHODS: Retrospective data analysis of 93 women undergoing TVS and surgery for DE in 2019 at a tertiary referral center for endometriosis. RESULTS: #Enzian compartment C (rectum) showed the highest rate of exact concordance with 74% of cases, which increased to 87% when a tolerance margin of a maximum of 3mm for TVS measurements was taken into account. For compartment B (uterosacral ligaments, parametria) and compartment A (vagina, rectovaginal space), the rates of exact concordance were slightly lower. In compartment O (ovary), high exact concordance rates similar to those observed for compartment C were observed. In compartment T (tubo-ovarian unit), most reliable estimations were seen for slight (TVS T1) and severe adhesions (TVS T3). There were only a few cases of missed lesions as well as false positives on TVS: Sensitivity was 100% for all compartments except for A and B left (97%) and FB (urinary bladder, 86%); specificity was 100% for FB, FI (other intestinal locations), FU (ureters) and O right, 86%-98% for A, B right, C, O left and FO (other extragenital lesions) and 70% for B left. CONCLUSION: The preoperative evaluation of the location and size of DE lesions by TVS in different #Enzian compartments is accurate, providing a detailed presurgical description of the extent of ovarian and deep endometriosis and associated minor or severe adhesions.

Comparison between Robotic Single-Site and Laparoendoscopic Single-Site Hysterectomy: Multicentric Analysis of Surgical Outcomes.

Background and Objectives: Minimally invasive surgery, especially the single-site approach, has demonstrated several advantages in the gynaecological setting. The aim of this study was to compare the surgical outcomes of single-site hysterectomy for benign conditions between the traditional laparoendoscopic approach and robotic surgery. MATERIALS AND METHODS: We consecutively enrolled 278 women between 2012 and 2019 in this multicentre trial. The patients underwent robotic single-site hysterectomy (RSSH) or laparoendoscopic single-site hysterectomy (LESSH) procedures with or without salpingo-oophorectomy for benign indications. Surgical parameters and surgical outcomes were analysed. RESULTS: There was a statistical difference between the two surgical techniques for total operative time (p = 0.001), set-up time (p = 0.013), and anaesthesia time (p = 0.001). Significant differences in intraoperative blood loss were observed (p = 0.001), but no differences were shown for blood transfusion or intraoperative or postoperative complications in the two groups. CONCLUSIONS: LESSH outperformed RSSH in terms of surgical performance and clinical outcomes, with no differences in adverse events.

Comparison of #Enzian classification and revised American Society for Reproductive Medicine stages for the description of disease extent in women with deep endometriosis.

STUDY QUESTION: How is endometriosis extent described by the #Enzian classification compared to the revised American Society for Reproductive Medicine (rASRM) stages in women undergoing radical surgery for deep endometriosis (DE)? SUMMARY ANSWER: The prevalence and severity grade of endometriotic lesions and adhesions as well as the total number of #Enzian compartments affected by DE increase on average with increasing rASRM stage; however, DE lesions are also present in rASRM stages 1 and 2, leading to an underestimation of disease severity when using the rASRM classification. WHAT IS KNOWN ALREADY: Endometriotic lesions can be accurately described regarding their localization and severity by sonography as well as during surgery using the recently updated #Enzian classification for endometriosis. STUDY DESIGN, SIZE, DURATION: This was a prospective multicenter study including a total of 735 women between January 2020 and May 2021. PARTICIPANTS/MATERIALS, SETTING, METHODS: Disease extent in women undergoing radical surgery for DE at tertiary referral centers for endometriosis was intraoperatively described using the #Enzian and the rASRM classification. MAIN RESULTS AND THE ROLE OF CHANCE: A total of 735 women were included in the study. Out of 31 women with rASRM stage 1, which is defined as only minimal disease, 65% (i.e. 20 women) exhibited DE in #Enzian compartment B (uterosacral ligaments/parametria), 45% (14 women) exhibited DE in #Enzian compartment A (vagina/rectovaginal septum) and 26% (8 women) exhibited DE in #Enzian compartment C (rectum). On average, there was a progressive increase from rASRM stages 1-4 in the prevalence and severity grade of DE lesions (i.e. lesions in #Enzian compartments A, B, C, FB (urinary bladder), FU (ureters), FI (other intestinal locations), FO (other extragenital locations)), as well as of endometriotic lesions and adhesions in #Enzian compartments P (peritoneum), O (ovaries) and T (tubo-ovarian unit). In addition, the total number of #Enzian compartments affected by DE lesions on average progressively increased from rASRM stages 1-4, with a maximum of six affected compartments in rASRM stage 4 patients. LIMITATIONS, REASONS FOR CAUTION: Interobserver variability may represent a possible limitation of this study. WIDER IMPLICATIONS OF THE FINDINGS: The #Enzian classification includes the evaluation of DE in addition to the assessment of endometriotic lesions and adhesions of the ovaries and tubes and may therefore provide a comprehensive description of disease localization and extent in women with DE. STUDY FUNDING/COMPETING INTEREST(S): No funding was received for this study. All authors declare that they have no conflict of interest. TRIAL REGISTRATION NUMBER: N/A.

Fertility-sparing treatment for serous borderline ovarian tumors with extra-ovarian invasive implants: Analysis from the MITO14 study database.

OBJECTIVE: Only 10-15% of serous borderline ovarian tumors (BOTs) with extra-ovarian disease have invasive implants, and conservative treatments have been rarely reported. The MITO14 is a multi-institutional retrospective study conducted with the aim of systematically collecting data from consecutive BOT patients. The present analysis reports the oncological and reproductive outcomes of women with serous BOT and invasive implants registered into the MITO14 database and conservatively treated between August 2002 and May 2019. METHODS: Thirteen patients (FIGO2014 stage II-III serous BOT with invasive implants) were recruited. Primary and secondary endpoints were, respectively, recurrence and death rates, and pregnancy and live birth rates. Only patients undergoing fertility-sparing surgery (FSS) were included, while patients were excluded in case of: age > 45 years; second tumor(s) requiring therapy interfering with the treatment of BOT. RESULTS: Median follow-up time from primary cytoreduction was 146 months (range 27-213 months). Eleven patients (84.6%) experienced at least one recurrence (median time to first relapse 17 months, range 4-190 months), all of these undergoing secondary surgery (FSS in 7). Five patients attempted to conceive: 3 achieved at least one pregnancy and 2 gave birth at least to a healthy child. At the end of the observation period, all patients were alive with no evidence of disease. CONCLUSIONS: Fertility-sparing treatment should be considered in a context of serous BOT with invasive implants. Despite the high rate of recurrence, FSS provides good chances of reproductive success without a negative impact on overall survival.

SUCCOR cone study: conization before radical hysterectomy.

OBJECTIVE: To evaluate disease-free survival of cervical conization prior to radical hysterectomy in patients with stage IB1 cervical cancer (International Federation of Gynecology and Obstetrics (FIGO) 2009). METHODS: A multicenter retrospective observational cohort study was conducted including patients from the Surgery in Cervical Cancer Comparing Different Surgical Aproaches in Stage IB1 Cervical Cancer (SUCCOR) database with FIGO 2009 IB1 cervical carcinoma treated with radical hysterectomy between January 1, 2013, and December 31, 2014. We used propensity score matching to minimize the potential allocation biases arising from the retrospective design. Patients who underwent conization but were similar for other measured characteristics were matched 1:1 to patients from the non-cone group using a caliper width ≤0.2 standard deviations of the logit odds of the estimated propensity score. RESULTS: We obtained a weighted cohort of 374 patients (187 patients with prior conization and 187 non-conization patients). We found a 65% reduction in the risk of relapse for patients who had cervical conization prior to radical hysterectomy (hazard ratio (HR) 0.35, 95% confidence interval (CI) 0.16 to 0.75, p=0.007) and a 75% reduction in the risk of death for the same sample (HR 0.25, 95% CI 0.07 to 0.90, p=0.033). In addition, patients who underwent minimally invasive surgery without prior conization had a 5.63 times higher chance of relapse compared with those who had an open approach and previous conization (HR 5.63, 95% CI 1.64 to 19.3, p=0.006). Patients who underwent minimally invasive surgery with prior conization and those who underwent open surgery without prior conization showed no differences in relapse rates compared with those who underwent open surgery with prior cone biopsy (reference) (HR 1.94, 95% CI 0.49 to 7.76, p=0.349 and HR 2.94, 95% CI 0.80 to 10.86, p=0.106 respectively). CONCLUSIONS: In this retrospective study, patients undergoing cervical conization before radical hysterectomy had a significantly lower risk of relapse and death.

SUCCOR quality: validation of ESGO quality indicators for surgical treatment of cervical cancer.

OBJECTIVE: To evaluate whether compliance with European Society of Gynaecological Oncology (ESGO) surgery quality indicators impacts disease-free survival in patients undergoing radical hysterectomy for cervical cancer. METHODS: In this retrospective cohort study, 15 ESGO quality indicators were assessed in the SUCCOR database (patients who underwent radical hysterectomy for International Federation of Gynecology and Obstetrics (FIGO) stage 2009 IB1, FIGO 2018 IB1, and IB2 cervical cancer between January 2013 and December 2014), and the final score ranged between 0 and 16 points. Centers with more than 13 points were classified as high-quality indicator compliance centers. We constructed a weighted cohort using inverse probability weighting to adjust for the variables. We compared disease-free survival and overall survival using Cox proportional hazards regression analysis in the weighted cohort. RESULTS: A total of 838 patients were included in the study. The mean number of quality indicators compliance in this cohort was 13.6 (SD 1.45). A total of 479 (57.2%) patients were operated on at high compliance centers and 359 (42.8%) patients at low compliance centers. High compliance centers performed more open surgeries (58.4% vs 36.7%, p<0.01). Women who were operated on at centers with high compliance with quality indicators had a significantly lower risk of relapse (HR=0.39; 95% CI 0.25 to 0.61; p<0.001). The association was reduced, but remained significant, after further adjustment for conization, surgical approach, and use of manipulator surgery (HR=0.48; 95% CI 0.30 to 0.75; p=0.001) and adjustment for adjuvant therapy (HR=0.47; 95% CI 0.30 to 0.74; p=0.001). Risk of death from disease was significantly lower in women operated on at centers with high adherence to quality indicators (HR=0.43; 95% CI 0.19 to 0.97; p=0.041). However, the association was not significant after adjustment for conization, surgical approach, use of manipulator surgery, and adjuvant therapy. CONCLUSIONS: Patients with early cervical cancer who underwent radical hysterectomy in centers with high compliance with ESGO quality indicators had a lower risk of recurrence and death.

Ultrasound Evaluation of Retrocervical and Parametrial Deep Endometriosis on the Basis of Surgical Anatomic Landmarks.

STUDY OBJECTIVES: To assess the value of combined transvaginal/transabdominal ultrasonographic evaluation performed by experienced examiners for deep infiltrating endometriosis (DIE) lesions of the retrocervical (torus uterinus and uterosacral ligaments) and parametrial areas and summarize the features and anatomic criteria for identification of these lesions and their extent in the above-mentioned pelvic compartments. DESIGN: Retrospective study. SETTING: A specialized endometriosis center in Avellino, Italy. PATIENTS: A retrospective cohort of patients who underwent laparoscopic surgery for clinically suspected DIE between January 1, 2014, and December 31, 2018, with a dedicated ultrasound (US) evaluation performed no more than 1 month before the intervention. INTERVENTIONS: Preoperative US findings and surgical reports were reviewed. Using the findings of laparoscopic surgery as the gold standard, the sensitivity and specificity of preoperative US evaluation for retrocervical and parametrial endometriotic lesions were calculated with the corresponding 95% confidence intervals. MEASUREMENTS AND MAIN RESULTS: A total of 4983 patients were included. US evaluation showed high diagnostic accuracy for DIE detection in the examined pelvic compartments, with sensitivity and specificity of 97% to 98% and 98% to 100%, respectively, for both retrocervical (torus uterinus and uterosacral ligaments insertion) and parametrial lesions. CONCLUSION: Parametrial extension of DIE indicates major surgical technical difficulties and risk of complications, and urologic and nerve-sparing procedures may be required in such cases. Preoperative evaluation of such scenarios will allow proper counseling of patients and facilitate adequate surgical planning in referral centers; moreover, when necessary, it can guide the constitution of a dedicated multidisciplinary surgical team as an alternative to treatment by a pelvic surgeon alone. Detailed imaging evaluation of DIE lesions and their extension is crucial for clinical management of affected patients. It can facilitate optimization of surgical timing and strategies, thereby potentially preventing ineffective, or even harmful, repeated procedures.

Totally Laparoscopic Resection with Transanal Natural Orifice Specimen Extraction for Deep Endometriosis Infiltrating the Rectum.

OBJECTIVE: To show the surgical steps used to perform a totally laparoscopic segmental rectal resection, with intracorporeal anastomosis and transanal natural orifice specimen extraction (NOSE), in a context of deep endometriosis. DESIGN: Step-by-step video demonstration of the technique. SETTING: Even though the combined use of intracorporeal anastomosis and NOSE has increasingly been investigated during the last decade, there is still lack of defined consensus, both in terms of patient eligibility and operative technique. In particular, experience with intracorporeal anastomosis and NOSE for treatment of deep rectal endometriosis is very limited. Preliminary reports have documented that a totally laparoscopic rectal resection is equally effective and safe compared with the conventional approach using an abdominal minilaparotomy for extracorporeal anastomosis and specimen retrieval. In comparison to the latter, intracorporeal anastomosis with NOSE seems to offer advantages in terms of less postoperative pain, fewer wound-related complications, better cosmetic results, quicker return of bowel function and shorter hospital stay. PATIENT: A 31-year-old woman with a history of constipation, dyschezia, dysmenorrhea, dyspareunia, and chronic pelvic pain unresponsive to hormonal therapies. Preoperative ultrasonography showed partial obliteration of the Douglas' pouch due to a rectal endometriotic nodule of 42 × 12 × 18 mm in contiguity with a deeply infiltrating retrocervical lesion of 13 × 3 × 17 mm. The rectal nodule resulted in the infiltration of the tunica muscularis with a distance of 12 cm from the anal verge and a circumferential extent of 45%. INTERVENTIONS: A 3-dimensional laparoscopic system was used. Rectal mobilization was performed according to our standardized technique [1]. After determining the proximal and distal resection margins, the rectum was transected using a tissue sealing-device. The resected specimen was placed in a retrieval bag and pulled out through the anus. Proximal and distal resection lines were closed using a 60 mm linear endo-stapler, and a totally intracorporeal, side-to-end anastomosis was performed using a 29 mm circular stapler. MAIN RESULTS: The overall operative time was 85 minutes. The estimated blood loss was 10 mL. Neither intra- nor postoperative complications occurred. The patient was discharged 5 days after surgery. The bowel endometriotic nodule measured 41 × 12 × 18 mm on the fresh unfixed specimen. CONCLUSIONS: Advanced surgical skills are needed to perform an effective and safe, totally laparoscopic rectal resection. The operative technique displayed in this video may contribute to the standardization of such surgical procedure. Accurate patient selection, including adequate preoperative evaluation, is of utmost importance for the best chance of surgical success.

Laparoscopic Single-Port versus Mini-Laparoscopic Hysterectomy: An International Study.

OBJECTIVES: Laparoendoscopic single-site surgery (LESS) and mini-laparoscopic surgery (Mini-LPS) have been performed with comparable results to conventional laparoscopy. However, there are few data on the comparison between them. Our main objective was to compare LESS and Mini-LPS in terms of surgical time, postoperative pain, and hospital stay in patients who underwent hysterectomy for benign pathology. DESIGN: It is a retrospective international multicentric study carried out in 5 centers including 2 Spanish and 3 Italian. METHODS: Data from patients who underwent hysterectomy for benign pathology between January 1, 2010, and December 31, 2015, were reviewed. We collected the clinical-pathological characteristics of the patients and the perioperative results. The main variables of the study were surgical time, the switch to oral analgesia, and the hospital stay. The two comparison groups in the study included patients undergoing hysterectomy for benign pathology by LESS or by Mini-LPS. The decision to perform the type of procedure was left to the discretion of the surgeon, based primarily on the surgical skills and experience of the center. All data were collected retrospectively by an online encrypted platform. RESULTS: 161 patients were included in the study. 104 (64.6%) patients underwent LESS hysterectomy and 57 (35.4%) Mini-LPS. Median surgical time was significantly longer in the LESS group when compared to the Mini-LPS group (120 vs. 75 min, respectively; p < 0.001). Moreover, longer median hospital stay was observed in the LESS group compared to Mini-LPS (48 vs. 36 h, respectively; p < 0.001). Conversion of the technique to conventional LPS was performed in 4 (2.5%) patients, all of them in the Mini-LPS group (p = 0.015). LIMITATIONS: It is a retrospective study with the biases that this implies. Furthermore, some variables have been incompletely registered in the database, which implies loss of information. This is a nonrandomized study since the decision to intervene with one or another technique was made by the surgeon, which generated 2 nonhomogeneous groups in terms of the number of patients. On the other hand, all the patients who underwent Mini-LPS hysterectomy belonged to the same center, which may have made these results center dependent. CONCLUSIONS: Significant shorter surgical time and shorter hospital stay were observed in patients undergoing Mini-LPS hysterectomy compared to LESS technique; however, intraoperative complications related to instrumentation flaws were higher in the mini-LPS group that required conversion to standard laparoscopy in all cases. Both ultra-minimally invasive techniques seem safe to perform hysterectomies for benign pathology and emphasize the importance in surgical training to adapt them to our current practice.

Practice changes in Italian Gynaecologic Units during the COVID-19 pandemic: a survey study.

The impact of Coronavirus disease 2019 pandemic on Italian Gynaecological Units practice and the compliance and satisfaction with available guidelines/recommendations is unknown. Therefore, a survey was conducted among all Italian Gynaecological Units Directors in April 2020. The response rate was 90% (135/150). 77.8% of centres performed surgery only for oncologic or not deferrable pathologies, and 9.6% was closed. 68.7% of directors were at least moderately satisfied by published guidelines/recommendations, but 94.8% of respondents identified limitations, mainly (83%) the absent definition of benign non-deferrable pathology. Responders considered as non-deferrable severe endometriosis (69.6%), endometriosis with organ failure/dysfunction (74.1%), and unresponsive symptomatic fibroids (89.6%). Despite guidelines/recommendations, respondents treated ovarian (77%) and endometrial (71.6%) cancer as usual. Only a minority of respondents reduced the laparoscopic approach (11.2%) and adopted all recommended surgical precautions (9.6%). Compliance with available guidelines/recommendations appears incomplete. Reconsidering guidelines/recommendations regarding oncological cases and specify non-deferrable benign pathologies would improve guidelines/recommendations compliance.Impact statementWhat is already known on this subject? The SARS-CoV-2 pandemic has profoundly influenced medical routine practice worldwide. Surgery units have been forced to reduce or even completely restrict their activity to re-allocate human resources. Many major international gynaecological societies have released statements and guidelines, providing various recommendations to guide practice changes. However, the impact of the SARS-CoV-2 pandemic on Italian Gynaecological Units practice and the compliance and satisfaction with available guidelines/recommendations is unknown.What do the results of this study add? Study results provide evidence showing how the SARS-CoV-2 pandemic has changed surgical activity in the Italian Gynaecological Units. Most centres reduced surgical activity, limiting surgery only for oncologic or not deferrable pathologies. Moreover, our research shows the level of compliance and satisfaction with available guidelines/recommendations and where they need to be improved. Most directors were at least moderately satisfied but identified different limitations. Guidelines/recommendations do not provide enough details, such as the absent definition of benign non-deferrable pathologies.What are the implications of these findings for clinical practice and/or further research? The limited compliance with available guidelines/recommendations and identified limitations suggest reconsidering guidelines/recommendations focussing on identified gaps. Provide more details, such as specifying non-deferrable benign pathologies, would improve guidelines/recommendations compliance.
