ObjectiveWhile human papillomavirus (HPV) has been shown to play a significant role in cervical cancer carcinogenesis (HPV associated cases), a considerable percentage of cervical cancers occur independently of HPV status (HPV independent).MethodsIn this retrospective study of 254 locally advanced cervical cancer patients treated with chemoradiotherapy and radical surgery, HPV genotypes were determined using the Anyplex II HPV28 kit that uses multiplex, real time polymerase chain reaction technology. The primary endpoints of this study were to evaluate the complete response to chemoradiotherapy (pathologic complete response), the presence of microscopic (<3 mm, pathologic micro partial response, group 1) and macroscopic (>3 mm, pathologic macro partial response, group 2) residual carcinoma in the cervix, and the persistence of metastatic lymph nodes (group 3) in HPV independent cervical cancers. Secondary endpoints were evaluation of disease-free survival and overall survival.ResultsOf 254 patients studied, 21 cases (8.3%) of cervical cancer were determined to be HPV independent. The percentage of pathologic complete response was found to be higher in the HPV associated group compared with the HPV independent group (pConclusionsThis study showed that HPV status at diagnosis could be a relevant factor for clinical outcomes in locally advanced cervical cancer patients.

Introduction: Sentinel lymph node (SLN) biopsy algorithm has been routinely applied in all endometrial endometrioid tumors, however, no studies analyzed the feasibility of SLN mapping in endometrioid variants (EV), which included villoglandular, secretory, ciliated cell, mucinous, and squamous differentiation. This study aimed to demonstrate the feasibility of SLN biopsy in EV of EC. Materials and methods: All patients undergoing minimally invasive surgical treatment for early-stage EC were included in the study. Patients were divided into 2 study groups: Group 1 which included patients with EV, and Group 2 which included patients with typical endometrioid histology. A propensity match analysis was performed according to age (≥65 years vs. no), BMI (≥30 kg/m2 vs. no), and LVSI (present vs. absent). Results: After a 1:5 propensity-matched analysis, a total of 458 patients were identified (Group 1 n = 77, Group 2 n = 381). Overall detection rate was not statistically significant between the EV and the typical endometrioid group (94.8% vs. 92.4%, p = 0.319). Furthermore, neither bilateral nor unilateral detection rate was different between the two groups (70.1% vs. 74.8%, p = 0.267, and 23.4% vs. 17.8%, p = 0.120). BMI ≥30 kg/m2 was the only factor influencing SLN failure (p = 0.013). SLN technique showed excellent sensitivity in both the EV (100% sensitivity, p < 0.001) and the typical endometrioid unit (93.8% sensitivity, p < 0.001). Conclusion: SLN research/detection for EV of endometrial cancer is a feasible and highly sensitive technique. Obesity was confirmed to be a risk factor for SLN failure.

ObjectiveEndometrial cancer is the most common gynecologic neoplasm. To date, international guidelines recommend sentinel lymph node biopsy for low-risk neoplasms, while systematic lymphadenectomy is still considered for high-risk cases. This study aimed to compare the long-term survival of high-risk patients who were submitted to sentinel lymph node biopsy alone versus systematic pelvic lymphadenectomy.MethodsPatients with high-risk endometrial cancer according to the 2021 European Society of Gynaecological Oncology/European Society for Radiotherapy and Oncology/European Society of Pathology risk classification were retrospectively analyzed. The primary aim of the study was to compare the long-term overall survival and disease-free survival of high-risk endometrial cancer patients undergoing sentinel lymph node biopsy versus systematic lymphadenectomy. A supplementary post-hoc survival analysis of cases with nodal metastasis was performed to compare sentinel lymph node and lymphadenectomy survival outcomes in this subset of patients.ResultsThe study enrolled 237 patients with histologically proven high-risk endometrial cancer. Patients were followed up for a median of 31 months (IQR 18–40). During the follow-up, 38 (16.0%) patients had a recurrence, and 19 (8.0%) patients died. Disease-free survival (85.2% vs 82.8%; p=0.74) and overall survival (91.3% vs 92.6%; p=0.62) were not different between the sentinel lymph node alone and lymphadenectomy groups. Furthermore, neither overall survival (96.1% vs 91.4%; p=0.43) nor disease-free survival (83.7% vs 76.4%; p=0.46) were different among sentinel lymph node alone and lymphadenectomy groups in patients with nodal metastasis.ConclusionsSentinel lymph node mapping alone in high-risk endometrial cancer appears to be an oncologically safe technique over a long observational time. Systematic lymphadenectomy in this population does not offer a survival advantage.

Introduction Endometrial cancer (EC) is the most common gynecological cancer. Sentinel lymph node (SLN) technique has been adopted worldwide and showed lower morbidity and superimposable survival outcomes than the systematic lymphadenectomy (LND). Although these encouraging results, no meta-analyzes were performed on surgical complications during SLN research among patients undergoing laparoscopic (L) versus robotic surgery (R). The present review aims to report surgical complications during laparoscopic versus robotic SLN technique. Methods The Preferred Reporting Items for Systematic reviews and Meta-Analyzes (PRISMA) and the Meta-analysis Of Observational Studies in Epidemiology (MOOSE) guidelines have been followed for the present meta-analysis. Results Six studies, including 769 participants, were included. L-LND resulted in a significantly higher risk of operative complications relative to L-SLN (RR 2.10 [95% CI 1.37 to 3.21]). The risk of complications was comparable between R-SLN and L-SLN (RR 2.32 [95% CI 0.04–121.02]) and between R-LND and L-LND (RR 2.17 [95% CI 0.04–126.69]). According to the SUCRA analysis, L-SLN and R-SLN had the highest chances of being ranked first among proposed surgical procedures (SUCRA 48.9% and 28.4% respectively). Conclusions Our study reported a lower surgical complications rate in patients undergoing L-SLN technique compared to L-LND. A lower rate of surgical complications was also reported for the R-SLN technique compared to the R-LND. Both laparoscopic and robotic SLN surgical techniques were found to be safe surgical procedures.

Background: The introduction of ultra-high-definition laparoscopic cameras (4K), by providing stronger monocular depth perception, could challenge the existing 3D technology. There are few available studies on this topic, especially in gynaecological setting. Objectives: Prospective, single institution, randomised clinical trial (NCT04209036). Materials and Methods: The two laparoscopes utilised were the 0°ULTRA Telescopes with 4K technology and the 0°3D-HD by Olympus. The surgeons were all trainees and in their last year of residency and who had obtained the certificate of first or second level of the Gynaecological Endoscopic Surgical Education and Assessment program - GESEA program. Twenty-nine patients with benign uterine pathology were enrolled. Main outcome measures: To compare if the use three-dimensional (3D) versus ultra-high-definition laparoscopic vision system (4K) for total laparoscopic hysterectomy performed by trainees was associated with a shorter operative time. Results: The 3D vision system did not prove to be superior to the 4K vision system. Operators reported significantly more vision-related side effects when using 3D than 4K. Completing the GESEA training program was the only factor with a positive and statistically significant impact on the overall time of the procedure, especially when greater dexterity and tissue handling were required. Conclusions: Neither technology used proved superior to the other, although operators showed a preference for 4K over 3D due to the lower number of visual side effects. Attendance at courses on laparoscopic simulators and training programs allowed trainees to demonstrate excellent surgical skills.

Nowadays, no standard approaches for follow up in ovarian cancer (OC) patients exist. While the role of ultrasound (US) is well defined in primary diagnosis of OC, it is still controversial during follow-up of surgically treated OC. The aim of this narrative review is to evaluate the role described in literature of US imaging in the early detection of OC recurrences. A review of the English literature present in PubMed and SCOPUS of the past 30 years regarding the use of US in recurrent ovarian cancer (ROC) has been performed. The following keywords were searched: "ultrasound and recurrent ovarian cancer" and "intraoperative ultrasound and recurrent ovarian cancer". A total of 15 articles were selected. US was mainly adopted in the detection of recurrent pelvic disease after debulking surgery, after fertility sparing surgery (FSS) and as an intraoperative tool for localization of OC recurrences. If introduced as a standard follow-up procedure, US may have a central role in the early detection of pelvic OC recurrence, in ovarian localization of relapses of borderline ovarian tumor (BOT) and early stages disease treated with FSS; it may also play an important role in the intraoperative localization of previously suspected secondary lesions.

Background Cytoreductive surgery is currently the main treatment for advanced epithelial ovarian cancer (OC), and several surgical maneuvers, including colorectal resection, are often needed to achieve no residual disease. High surgical complexity carries an inherent risk of postoperative complications, including anastomosis leakage (AL). Albeit rare, AL is a life-threatening condition. The aim of this single-center retrospective study is to assess the AL rate in patients undergoing colorectal resection and anastomosis during primary surgery for advanced epithelial OC through a standardized surgical technique and to evaluate possible pre/intra- and postoperative risk factors to identify the population at greatest risk. Methods A retrospective analysis of clinical and surgical characteristics of 515 patients undergoing colorectal resection and anastomosis during primary or interval debulking surgery between December 2011 and October 2019 was performed. Several pre/intra- and postoperative variables were evaluated by multivariate analysis as potential risk factors for AL. Results The overall anastomotic leakage rate was 2.9% (15/515) with a significant negative impact on postoperative course. Body mass index 2, preoperative albumin value lower than 30 mg/dL, section of the inferior mesenteric artery at its origin, and medium–low colorectal anastomosis ( Conclusions AL is confirmed to be an extremely rare but severe postoperative complication of OC surgery, being responsible for increased early postoperative mortality. Preoperative nutritional status and surgical characteristics, such as blood supply and anastomosis level, appear to be the most significant risk factors.

The objective of the present study was to define and validate an anastomotic leak prognostic score based on previously described and reported anastomotic leak risk factors (OVA-LEAK: https://n9.cl/ova-leakscore) and to establish if the use of OVA-LEAK score is better than clinical criteria (surgeon's choice) selecting anastomosis to be protected with a diverting ileostomy.This is a retrospective, multicentre cohort study that included patients who underwent cytoreductive surgery for primary advanced or relapsed ovarian cancer with colorectal resection and anastomosis between January 2011 and June 2021. Data from patients already included in the previous predictive model were not considered in the present analysis. To validate the performance of our logistic regression model, we used the OVA-LEAK formula (Annex I: https://n9.cl/ova-leakscore) for estimating leakage probabilities in a new independent cohort. Then, receiver operating characteristic (ROC) analysis was performed and area under the curve (AUC) was used to measure the performance of the model. Additionally, the Brier score was also estimated. 95% confidence intervals (CI) for each of the estimated performance measures were also calculated.848 out of 1159 recruited patients were finally included in the multivariable logistic regression model validation. The AUC of the new cohort was 0.63 for predicting anastomotic leak. Considering a cut-off point of 22.1% to be 'positive' (to get a leak) this would provide a sensitivity of 0.45, specificity of 0.80, positive predictive value of 0.09 and negative predictive value of 0.97 for anastomotic leak. If we consider this cut-off point to select patients at risk of leak for bowel diversion, up to 22.5% of the sampled patients would undergo a diverting ileostomy and 47% (18/40) of the anastomotic leaks would be 'protected' with the stoma. Nevertheless, if we consider only the 'clinical criteria' for performing or not a diverting ileostomy, only 12.5% (5/40) of the leaks would be 'protected' with a stoma, with a rate of diverting ileostomy of up to 24.3%.Compared with subjective clinical criteria, the use of a predictive model for anastomotic leak improves the selection of patients who would benefit from a diverting ileostomy without increasing the rate of stoma use.

Conflicting data exists on the impact of Body Mass Index (BMI) on sentinel lymph-node (SLN) detection. The primary study endpoint was to investigate the impact of obesity on overall detection rate, bilateral mapping, and mapping failure rate of SLN. In addition, we evaluated possible differences in terms of surgical management and "empty-packet dissection" rate among obese and non-obese patients.Multicenter, propensity-matched, retrospective study. Patients with apparent early-stage endometrial cancer were included. Study population was divided into women with BMI/≥ 30 (Group-1 and Group-2). To lower the selection bias, a propensity-matched analysis was performed. Matching was based on histotype (endometrioid vs non-endometrioid), age (/≥65 years old), and presence of lymph-vascular space invasion.Eight-hundred forty-four women were enrolled. After a 1:1 propensity-matched analysis, 764 patients were identified (Group-1 n = 382, Group-2 n = 382). A 1.156-fold increase in the risk of mapping failure for every 5 units of BMI increase was found (OR 1.156, 95% CI 1.033-1.294, p = 0.012), with a consequently decrease in bilateral mapping and overall detection rate (respectively OR 0.865, 95% CI 0.773-0.968, p = 0.012 and OR 0.785, 95% CI 0.670-0.920, p = 0.003). Obese patients were surgically under-staged in 9.4% of cases and showed an 8.2% of empty packet dissection (surgical under-staging: 5.0% vs 9.4%, p = 0.017; empty-packet dissection: 3.9% vs 8.2%, p = 0.022).BMI was confirmed as a statistically relevant predictor of mapping failure and decreased overall detection rate. In addition, obese women had a significantly higher odds of empty packet dissection.

IntroductionA current challenge for endometriosis surgery is to correctly identify the localizations of disease, especially when small or hidden (occult endometriosis), and to exactly define their real extension. The use of near-infrared radiation imaging (NIR) after injection of indocyanine green (ICG) represents one of the most encouraging method. The aim of this study is to assess the diagnostic value of NIR-ICG imaging in the surgical treatment of endometriosis compared with the standard of treatment.Material and MethodsThe Gre-Endo trial is a prospective, single-arm study (NCT03332004). After exploring the operatory field using the white light (WL) mode, patients were injected with ICG and then observed in NIR mode. All suspected areas were classified and chronicled according to lesions visualized only in WL, NIR-ICG, or in the combination of both. Lesion not visualized in WL was considered as suspect occult lesion (s-OcL). In addition, a random control biopsy from an apparent negative peritoneum visualized in WL and NIR-ICG imaging was taken for all patients (control cases). All lesions removed were considered “suspect endometriosis” until pathology.ResultsFifty-one patients were enrolled between January 2016 and October 2019. A total of 240 suspected lesions have been identified with both methods (WL + NIR-ICG). Two hundred and seven (86.2%) lesions out of the overall 240 were visualized with WL imaging, and 200 were confirmed to be pathologic (true positive for WL). The remaining 33/240 (13.75%) (false negative for WL) lesions were identified only with NIR-ICG imaging and collected as s-OcL. All 33 s-OcLs removed were confirmed to be pathologic (c-OcL = 100%). NIR-ICG vision showed PPV of 98.5%, NPV of 87.1%, Se of 87%, and Sp of 98.5%, confirming that this kind of imaging is an excellent diagnostic and screening test (p = 0.001 and p = 0.835, according to McNemar’s and Cohen’s kappa tests, respectively).ConclusionsThe use of NIR-ICG vision alone and combined with WL showed good results in intraoperative detection rate and fluorescence-guided surgery of endometriosis. Furthermore, NIR-ICG allowed surgeons to remove occult lesions that otherwise would remain, leading to possible greater postoperative pain and a higher risk of persistence and relapse.

Introduction/Background* Uterine carcinosarcomas (UCSs) are aggressive biphasic malignancies, with a high grade carcinomatous/epithelial component and a high grade sarcomatous/mesenchymal counterpart. Several studies identified the carcinomatous part as the main factor affecting the aggressive behaviour of UCSs. However, other studies reported that the sarcomatous component, especially the presence of heterologous elements, was associated with a worse prognosis. The prognostic ‘driving force’ is not completely clear for these kind of tumours. For this reason, the aim of our study was to evaluate the impact of the sarcomatous component (Homologous vs Heterologous) on the overall survival (OS) and progression-free survival (PFS). Methodology This is a multicenter observational retrospective study conducted in patients with stage I and II UCSs. Result(s)* Ninety-five women with histological diagnosis of early stage UCSs were retrieved: 60 (63.2%) had tumors with homologous sarcomatous components, and 35 (36.8%) with heterologous. Tumors with a sarcomatous heterologous component were significantly larger than the homologous (T ≥ 50 mm: 82.9% vs 51.7%, p-value=0.002) and presented more often lymph-vascular space invasion (62.9% vs 25.9% respectively in patients with heterologous and homologous component, p-value=0.001). At univariate analysis, a stromal invasion ≥ 50%, the presence of clear cell, serous or undifferentiated carcinomatous component, the heterologous sarcomatous component and the FIGO stage IB and II were shown to be variables with a statistically significant negative impact on PFS. Similarly, a depth of invasion ≥ 50%, the heterologous sarcomatous component and the FIGO stage IB and II were statistically negative prognostic factors also concerning OS. At multivariate analysis, only the heterologous sarcomatous component was confirmed to be a statistically significant negative prognostic factor both on PFS (HR 2.362, 95% CI 1.207-4.623, p-value=0.012) and on OS (HR 1.950, 95% CI 1.032-3.684, p=0.040). Conclusion* In conclusion, in our large series of UCSs, both carcinomatous and sarcomatous components played a role in tumor progression and patients’ survival. However, only the sarcomatous component retained a statistical significance at the multivariable model suggesting its preeminent prognostic role in early stage UCSs.

Introduction/Background* Obese patients pose both surgical and anesthetic challenges, as their comorbidities contribute to adverse outcomes. In this setting, minimally invasive approach and the introduction of the Sentinel Lymph-Node (SLN) algorithm in endometrial cancer (EC) treatment acquire a particular relevance, allowing to reduce both operative times and surgical difficulties. However, conflicting data exists on the impact of Body Mass Index (BMI) on SLN detection. The primary study endpoint was to investigate the impact of obesity on overall detection rate, bilateral mapping, and mapping failure rate. In addition, we evaluated possible differences in terms of surgical management and ‘empty packet dissection’ rate among the two study groups. Methodology Multicenter, propensity-matched, retrospective study. Data of patients with apparently early-stage EC were retrospectively retrieved. Study population was divided into women with BMI Result(s)* Eight-hundred forty-four women were enrolled in the study. After a 1:1 propensity matched analysis, a total of 764 patients were identified (Group-1 n=382, Group-2 n=382). A 1.156-fold increase in the risk of mapping failure for every 5 units of increase in BMI (OR 1.156, 95% CI 1.033-1.294, p=0.012) was found, with a consequently decrease in bilateral mapping and overall detection rate (respectively OR 0.865, 95% CI 0.773-0.968, p=0.012 and OR 0.785, 95% CI 0.670-0.920, p=0.003) (figure 1). Furthermore, in the group of obese patients, in 25 cases (7.4%) the SLN dissection did not lead to the identification of lymph-node tissue at final histopathological examination (’empty packet dissection’) (Group1 vs Group 2: 3.9% vs 7.4%, p=0.046) (table 1). Conclusion* Controlling for the variables that have been proved to negatively influence the SLN detection rate, BMI was confirmed as a statistically relevant predictor of mapping failure. In addition, obese women had a significantly higher odds of empty packet dissection, which could lead to an un-intended surgical understaging.

Postoperative chylous ascites is a rare complication from operative trauma to the cisterna chyli or lymphatic vessels in the retroperitoneum. In the present study, we aimed to identify the incidence of postoperative chylous ascites in patients treated for ovarian cancer and to describe its management. We retrospectively reviewed all patients submitted to surgery for ovarian cancer at our Institution from October 2016 to November 2018. We analyzed the clinicopathological features, including the primary tumor histology, stage, grade, surgical procedure, median number of harvested pelvic and para-aortic lymph nodes. We described our experience in the diagnosis and management of chylous ascites. Five hundred and forty-six patients were submitted to surgery for ovarian cancer and 298 patients received pelvic and/or para-aortic lymphadenectomy. Chylous ascites occurred in 8 patients with an incidence of 1.4% in the overall population and a 2.68% among patients receiving lymphadenectomy. All patients received total parenteral nutrition (TPN) with Olimel N4E 2000mL (Baxter®) and somatostatin therapy with 0.2mL per 3 times/day for a median of 9days (range 7–11). Median hospital stay was 15days (range 7–16). All patients were successfully managed conservatively and none required surgical correction. Conservative management of chylous ascites with TPN, somatostatin and paracentisis is feasible and effective. These data should be confirmed by prospective multicentric studies.

Objective The aim of this study was to describe one of the largest series of disseminated peritoneal leiomyomatosis (DPL) and its malignant counterpart, evaluating possible risk factors for both the benign and malignant condition, and highlighting any differences between them in terms of surgical and clinical management. Study Design Clinical, surgical and histopathological characteristics of patients diagnosed with DPL (group 1) and malignant-DPL (group 2), between July 2010 and July 2020, were retrospectively retrieved. Results A total of 14 benign and 5 malignant cases were selected. The duration of preoperative hormonal therapy was significantly longer in the benign condition while malignant DPL showed significantly larger lesions (median nodule size: 12 cm). However, surgical procedures and surgical outcomes did not differ among the two conditions, with highly complex surgery and relatively high post-operative complications in both groups. Conclusion Preoperative discrimination between benign and malignant DPL is challenging. Given the high surgical complexity required in both cases, addressing patients to referral cancer centers is strictly recommend, in order to offer them the best possible treatment and allowing a continuous and accurate collection of clinical information that might be crucial for further studies.

ObjectiveThe incidence of endometrial cancer is increasing in elderly people. Considering that aging progressively affects lymphatic draining function, we aimed to define its impact on IGC uptake during SLN mapping.MethodsA multicenter retrospective cohort of endometrial cancer patients with apparently early-stage endometrial cancer undergoing complete surgical staging with SLN dissection was identified in four referral cancer centers from May 2015 to March 2021. Patients were classified in Group 1 (ResultsA total of 844 patients were enrolled in the study (499 in Group 1 and 395 in Group 2). The overall detection rate, the successful bilateral mapping, and the mapping failure rate of the SLN were 93.8% vs. 87.6% (p = 0.002), 77.1% vs. 66.8% (p = 0.001), and 22.9% vs. 33.2% (p = 0.001), respectively, in Group 1 vs. Group 2. The advanced age affects the anatomical distribution of the SLN leading to a stepwise reduction of “unexpected” mapping sites (left hemipelvis: p < 0.001; right hemipelvis: p = 0.058). At multivariate analysis age ≥ 65 (OR: 1.495, 95% CI: 1.095–2.042, p = 0.011), BMI (OR: 1.023, 95% CI: 1.000–1.046, p = 0.047), non-endometrioid histotype (OR: 1.619, 95% CI: 1.067–2.458, p = 0.024), and LVSI (OR: 1.407, 95% CI: 1.010–1.961, p = 0.044) represent independent predictors of unsuccessful mapping. Applying binomial logistic regression analysis, there was a 1.280-fold increase in the risk of failed mapping for every 10-year-old increase in age (OR: 1.280, 95% CI: 1.108–1.479, p = 0.001). A higher rate of surgical under-staging (0.9% vs. 3.3%, p = 0.012) and adjuvant undertreatment (p = 0.018) was reported in Group 2.ConclusionsOld age represents a risk factor for SLN mapping failure both intrinsically and in relation to the greater incidence of other independent risk factors such as LVSI, non-endometrioid histotype, and BMI. Surgeons should target the usual uptake along UPP during the SLN dissection in this subgroup of patients to minimize mapping failure and the consequent risk of surgical under-staging and adjuvant undertreatment.

Gynecological tumor treatment, including cervical cancer (CC) treatment, often leads to iatrogenic premature menopause. This highlights the critical importance of investigating indications for hormone replacement therapy (HRT), as most patients, thanks to the improvement in diagnosis and treatment, have to deal with the sequelae of their cancer treatments for many years. This systematic review aims to provide an overview of the current knowledge regarding the risks of HRT and CC. In particular, we aim to investigate whether the use of HRT can increase CC incidence, and evaluate its risk in CC survivors. A systematic review, in agreement with PRISMA guidelines, of the English literature present in PubMed and SCOPUS has been performed. A total of 2805 articles have been screened, of which 10 were considered eligible. Several studies reported a significantly reduced risk of developing cervical squamous cell carcinoma in postmenopausal women treated with HRT, while a weak increase in the incidence of adenocarcinoma has been shown. No evidence reports a harmful effect of HRT on CC oncological outcome, while several benefits, in terms of reduced metabolic risk and increased quality of life, have been described, thus concluding that HRT should be offered to young CC survivors for the management of early menopause.

Introduction 2Department of Woman, Child and Public Health, Fondazione Policlinico Universitario A. Gemelli IRCCS, Italy Complete disease removal during cytoreductive surgery for AEOC is the main prognostic factor for both PDS and IDS. While a unanimous consensus exists on the RT=0 during PDS, the same is not true for IDS. Many surgeons do not consider necessary the removal of macroscopically normal or with apparent scarring areas peritoneum. This study aims to establish whether the intraoperative visual assessment can be a sufficiently sensitive tool to identify the presence or absence of residual disease. Methods Observational retrospective study. Pre-operative, surgical and histopathological features of patients subjected to IDS with visually-suspected (figure 1) or certain (figure 2) residual disease at the level of the right diaphragmatic peritoneum, have been collected. Results The study included 155 patients, with 92 patients classified as patients with ‘Visually-Pathologic diaphragmatic peritoneum’ (group-1) and 63 as patients with Visually-Suspected diaphragmatic peritoneum’(group-2). In group-1, all diaphragmatic specimens resulted positive, while group-2 showed 19% of patients with negative histological results and 81% with positive specimens. Visual examination showed a sensitivity of 64.3% and a specificity of 100%. PPV has been of 100% while NPV has been of 19%. Accuracy was of 67% (k=0.218). Frozen section evaluation was applied in 28 cases, and showed an accuracy of 92.6% (k=0.700). Conclusions Visually suspected areas often hide micro-macroscopic residual disease after chemotherapy. Frozen section of suspicious areas could be the key to perform a patient tailored surgery.

Current guidelines for complete surgical staging in early-stage ovarian cancer recommend systematic lumbo-aortic and pelvic lymphadenectomy,[1][1] despite their controversial therapeutic value with only 14% of patients upstaged.[2][2] Sentinel lymph node (SLN) detection with indocyanine green in

Introduction: Recto-vaginal endometriosis surgical management needing partial colpectomy is a surgically challenging condition and has been associated with a notable risk of major postoperative complications. In the present study we sought to compare feasibility and safety of total laparoscopic (TL) and vaginal-assisted (VA) routes in women affected by symptomatic recto-vaginal endometriosis with vaginal mucosa infiltration scheduled for minimally invasive surgery. Material and methods: Multi-centric, retrospective cohort study on medical records of consecutive reproductive age women submitted to complete macroscopic eradication of symptomatic recto-vaginal endometriosis with vaginal mucosa infiltration between March 2013 and November 2017. The two groups were compared in terms of preoperative data and surgical outcomes. Results: 84 women were included in the study (TL=57 and VA=27). The two groups were comparable in terms of preoperative, surgical and postoperative data. The major postoperative complications rate was 5.3% (3 of 57) in the TL group and 7.4% (2 of 27) in the VA group, without a significant difference. In the TL group we reported one case of bowel anastomosis dehiscence and two cases of pelvic abscess. In the VA group, one case of small bowel perforation after extensive adhesiolysis treated with ileal resection and one case of rectal sub-occlusion after segmental resection and mechanical anastomosis were noticed. Conclusions: In women affected by recto-vaginal endometriosis with vaginal mucosal infiltration, perioperative outcomes do not seem to be influenced by the surgical route adopted.

In patients undergoing debulking surgery for ovarian cancer (OC), bevacizumab-combined chemotherapy has been reported to be associated with an increased incidence of adverse events (AEs). Reports in the literature have noted the overall morbidity of bevacizumab to be between 3.7% and 9%. The aim of this study is to report uncommon and unusual manifestations of morbidity in surgical cases performed at our third level referral centers for gynecologic oncology. Additionally, we review the rare and severe bevacizumab-related complications that have been described in the literature. We defined as "extreme", the particularly rare and/or severe complications up to determining a life-threatening condition or death, which are related to the use of bevacizumab. A case-series of extreme complications registered at our institutions were reported. In addition, a literature search of the PubMed, MEDLINE and EMBASE electronic databases was performed for this review. The studies collected included: 8 randomized controlled trials (RCT) and 5 prospective observational, 1 prospective phase-IV, 10 prospective phase-II, 2 prospective phase-I, and 20 retrospective studies, as well as 9 case reports. Bevacizumab was administered as primary treatment in adjuvant and neo-adjuvant setting in 16 and 5 studies respectively, as treatment for recurrence in 36 trials, and for secondary cytoreductive surgery (SCS) in 3 studies. The overall population administered with bevacizumab numbered 7,096 women. Extreme complications were observed in 591 patients, with a morbidity rate of the 8.3%. Overall, central nervous system (CNS), cardiovascular, gastrointestinal (GI) and primary infectious complications were seen in 22 patients (0.3%), 261 patients (3.7%), 159 patients (2.2%), and 8 patients (0.13%), respectively. Hemorrhagic and wound complications occurred in 18 women (0.25%), and 112 women (1.6%), respectively. Extreme complications related to the use of bevacizumab are rare, and often go unrecognized. The recognition and immediate management of such rare and life-threatening complications in patients treated at third level referral centers could significantly improve patient survival.

Segmental resection has been generally associated with increased peri-operative risk of major complications. While major complications are widely acknowledged, minor complications, such as slight, to moderate infections, peripheral sensory disturbances, bladder voiding dysfunction, postoperative urinary obstruction, and sexual disorders are less reported. The aim of this study is to investigate the surgery-related complications and functional disorders, as well as to evaluate their persistence after long-term follow-up in women undergone segmental resection for deep infiltrating endometriosis. Special attention is given to evaluating impairments of bowel, bladder, and sexual function. All clinical data obtained from medical records of women who underwent segmental resection for intestinal endometriosis between October 2005, and November 2017, in Catholic University Institutions. Perioperative morbidity was classified by Extended Clavien–Dindo classification. Postoperative intestinal, voiding, and sexual morbidity was estimated by the compilation of specific questionnaires. Fifty women were included in the study. Forty-three high colorectal resections (86%), 6 low resections (12%), and 1 ultra-low resection (2%) were performed, while in 3 cases (6%) multiple resections were needed. The overall complication rate was 44%. Nineteen women (38%) experienced early complications and 3 women (6%) late complications. Long-term functional postoperative complications were composed of intestinal in 30%, urinary in 50%, and sexual in 64% of the study population. Median follow-up was 55.5 months. Segmental resection, when indicated, offers a radical and feasible approach for bowel deep infiltrating endometriosis, resulting in an improved general quality of life. The bowel and bladder complications appear to be acceptable and often reversible. Postoperative sexual dysfunctions, such as anorgasmia and insufficient vaginal lubrication, appear to persist over time. Surgeons and women have to be aware of the incidence of this kind of complications.

Introduction: The complete surgical removal of endometriosis lesions is not always feasible because some implants may be very small or hidden. The use of intraoperative near-infrared radiation (NIR) imaging after intravenous injection of indocyanine green (ICG) coupled with robotic technical advances, including 3-dimensional (3D) and high-resolution vision, might improve detection rates. Material and methods: This is a retrospective, multicenter case-control study (Canadian Task Force classification II-2) on medical records of women with endometriosis who underwent surgery at the Catholic University of Rome (Controls) and the University of Bologna (Cases) between January 2016 and March 2018. Surgical and post-surgical data from the procedures were collected. We compared the visual detection rate of endometriotic lesions using near-infrared radiation imaging after intravenous injection of indocyanine green (NIR-ICG) in Real 3D (Cases) with the 2D Camera approach (Controls) in symptomatic women with pelvic endometriosis. Results: Twenty cases were matched as closely as possible with 27 controls. The numbers of suspected lesions identified both with the white light and the NIR-ICG approach were 116 and 70 in the Controls (2D) and Cases (3D), respectively. Among them, 16 of 116 controls (13.8%) and 12 of 70 cases (17.1%) were identified using only NIR-ICG imaging and collected as occult lesions (P=.536). The overall NIR-ICG lesion identification showed a positive predictive value of 97.8%, negative predictive value of 82.3%, sensitivity of 82.0%, and specificity of 97.9% for the Control group, and a positive predictive value of 100%, negative predictive value of 97.1%, sensitivity of 97.1%, and specificity of 100% for the Case group, confirming that NIR-ICG imaging is a good diagnostic and screening test (P=.643 and P=.791, according to the Cohen κ tests, respectively for the laparoscopic and robotic groups). Conclusions: The few differences observed did not seem to be clinically relevant, making the 2 procedures comparable in terms of the ability to visually detect endometriotic lesions. Further prospective trials are needed to confirm our results.

Purpose: To evaluate the incidence, predictors and clinical outcome of pancreatic fistulas in patients receiving splenectomy during cytoreductive surgery for advanced or recurrent ovarian cancer. Methods: Data of women who underwent splenectomy during cytoreduction for advanced or recurrent ovarian cancer from December 2012 to May 2018 were retrospectively retrieved from the oncological databases of five institutions. Surgical, post-operative and follow-up data were analysed. Results: Overall, 260 patients were included in the study. Pancreatic resection was performed in 45 (17.6%) women, 23 of whom received capsule resection alone, while 22 required tail resection. Hyperthermic intraperitoneal chemotherapy (HIPEC) was administered in 28 (10.8%) patients. In the overall population, a pancreatic fistula was detected in 32 (12.3%) patients, and pancreatic resection (p-value = 0.033) and HIPEC administration (p-value = 0.039) were associated with fistula development. In multivariate analysis, HIPEC (OR = 2.573; p-value = 0.058) was confirmed as a risk factor for fistula development in women receiving splenectomy alone, while concomitant cholecystectomy (OR = 2.680; p-value = 0.012) was identified as the only independent predictor of the occurrence of pancreatic fistulas in those receiving additional distal pancreatectomy. Although the median length of hospital stay was higher in women with pancreatic leakage (p-value = 0.008), the median time from surgery to adjuvant treatment was not significantly increased. Conclusion: HIPEC was identified as a risk factor for pancreatic fistulas in patients who underwent splenectomy alone, while concomitant cholecystectomy was the only independent predictor of fistula in those receiving additional pancreatectomy. The development of pancreatic leakage was not associated with increased post-operative mortality or delay in the initiation of chemotherapy.

Study Objective To evaluate near-infrared radiation imaging with intravenous indocyanine green (NIR-ICG) during laparoscopic intervention to identify endometriosis lesions. Design A single-center, prospective, single-arm pilot study (Canadian Task Force classification II-2). Setting An academic tertiary care and research center. Patients Twenty-seven patients with symptomatic endometriosis were enrolled. Interventions Patients underwent laparoscopic surgery using a laparoscopic system prototype with NIR-ICG. Measurements and Main Results A total of 116 suspected endometriosis lesions were removed from 27 patients. One hundred lesions had already been visualized in white light imaging by an expert surgeon; the remaining 16 were detected and removed using NIR-ICG. A total of 111 specimens were positive for endometriosis pathology. Positive predictive value of 95% and 97.8% and negative predictive value of 86.2% and 82.3% were found by white light imaging and NIR-ICG, respectively, with sensitivity of 85.6% and 82% and specificity of 95.2% and 97.9%, respectively. Conclusion NIR-ICG may be a tool for intraoperative diagnosis, confirmation of visible endometriosis lesions, and a marker for identifying occult endometriosis. Further prospective studies with a larger population sample are warranted to validate these encouraging preliminary results.

Ovarian cancer is the most lethal of all gynecologic cancers.1 Primary debulking surgery (PDS) with achievement of no residual tumor (RT, 0) still is the recommended treatment, and the one with the greatest prognostic impact.2,3 Given the usual disease spread, several surgical procedures often are needed, and one of the most frequent is rectosigmoid resection.4 Anastomotic leak is the most feared complication. Other common complications are persistent urinary, defecatory, and sexual dysfunction due to autonomic nervous system injuries during surgery.5 Even if mesorectal resection is not deemed part of the treatment paradigm for advanced ovarian cancer (AOC), total mesorectal excision (TME) is the most common surgical technique used. However, for selected cases, with detection of no lymphadenopathies at the origin of the of the inferior mesenteric artery and a favorable ratio between the length of the left colon and the extent of the bowel carcinomatosis, a mesorectal-sparing resection with the preservation of the superior rectal artery and the mesorectal tissue should be pursued. This report presents the case of a 54-year-old woman with a diagnosis of FIGO stage 3C AOC who underwent PDS. The video (video 1) provides a step-by-step description of the surgical technique adopted for colorectal resection with mesorectal-sparing technique. Rectosigmoid mesorectal-sparing resection is feasible and could be a viable option for selected cases of AOC, maximizing the blood supply to colorectal anastomosis while minimizing the risk of both anastomotic leak and pelvic autonomic nervous system dysfunction.6.

To compare survival outcomes and peri-operative complications in patients with advanced ovarian cancer with 1-10 mm residual disease (RD) at primary debulking surgery (PDS) versus those achieving no gross residual disease (NGR) at interval debulking surgery (IDS).Patients operated with the intent of complete cytoreduction for epithelial ovarian/fallopian tube/primary peritoneal cancer, FIGO stage IIIC-IV, RD 1-10 mm at PDS and NGR at IDS, between 01/2010 and 12/2016, were retrospectively included. All patients had at least 2-years of follow-up completed.207 patients were included (59 PDS and 148 IDS). Patients in PDS group were younger and had a higher surgical complexity score. There was a higher rate of intra- and major early post-operative complications in the group of PDS vs IDS (16.9% vs 1.3% and 28.8% vs 2.0%, p 0.0001 respectively). After a median follow up of 56.4 months (range 59.2-65.4), 117 (56.5%) patients died of disease in the whole population. Forty-eight (81.4%) patients had progression/recurrent disease in the PDS group and 120 (81.1%) in the IDS group. Median PFS was 16.2 months and 18.9 months for PDS and IDS group, respectively (p = 0.111). Median OS was 41.4 months and 52.4 months for PDS and IDS group, respectively (p = 0.022).IDS should be considered the preferred treatment in case millimetric residual disease is expected at PDS in view of the superimposable PFS and the reduced number of perioperative complications.

Introduction/Background The aim of the surgical treatment of advanced ovarian cancer is to completely remove all macroscopic disease.To achieve optimal cytoreduction, the use of extensive upper abdominal surgery has become widely accepted.Although the disease doesn’t usually invade the splenic parenchyma, the capsule may commonly be infiltrated. These metastases may be difficult to be dissected from the pancreatic tail and a partial pancreatic resection en bloc with spleen may be required. The objective of this study is to evaluate predictors and clinical outcome of pancreatic fistula in patients receiving splenectomy for advanced or recurrent ovarian cancer. Methodology Data of women receiving splenectomy during cytoreductive surgery for advanced or recurrent ovarian cancer from December 2012 to May 2018 were retrospectively retrieved from the oncological databases of five institutions. Criteria’s used to identify pancreatic leaks were measurement of lipase and amylase level on peri-pancreatic drainage fluid, imaging and abdominal pain referable to pancreatitis.Surgical and post-operative data were analyzed. Results Overall 260 patients were included in the study.Pancreatic resection was performed in 45 (17.6%) women, among them 23 patients received only pancreatic capsule resection and 22 received distal pancreatic tail resection. Intraperitoneal hypertermic chemotherapy (HIPEC) was performed in 28 (10.8%) cases. Pancreatic fistula was detected in 32 (12.3%) cases. At multivariable analysis pancreatic resection (OR: 2.064; p: 0.040), in particular pancreatic tail resection (OR:3.055; p: 0.003) and HIPEC administration (OR: 1.910; p: 0.057) were identified as independent predictors of pancreatic fistula. Conclusion Twelve percent of patients who received splenectomy during cytoreductive surgery for ovarian cancer developed a pancreatic leak.Distal pancreatectomy and HIPEC administration have been identified as independent predictors of pancreatic fistula in this subset of patients. No significant delay in initiation of adjuvant chemotherapy was observed in women with leakage. Disclosure Nothing to disclose.

Introduction/Background Although the non-inferiority in overall survival (OS) of neoadjuvant chemotherapy (NACT) compared to primary debulking surgery (PDS) has been prospectively demonstrated, complete cytoreduction remains the most powerful determinants of survival among patients with stage III–IV epithelial ovarian carcinoma. In this setting, our study aims to compare survival outcomes between patients with 1–10 mm residual disease at primary debulking surgery (PDS) versus those achieving no gross residual disease (NGR) at interval debulking surgery (IDS). Methodology We retrospectively reviewed patients treated in our Institution from 1/2010 to 12/2016. 151 patients were included. Among them, 50 were allocated in PDS group (Cases) and 101 in IDS group (Controls). Patients were matched for clinicopathologic characteristics and appropriate statistical tests were used. Results No statistically significant differences were found between the two groups, except for a significant difference in median laparoscopic PIV at time of diagnosis, being lower in the Cases with respect to Controls (p After a median follow up of 55.3 months, 130 (86.1%) progression/recurrences and 72 (47.7%) deaths were registered. Median PFS was 16.0 and 18.3 months for PDS and IDS group respectively (p=0.456); median OS was 48.0 and 60.2 months in for PDS and IDS group respectively (p=0.426). Subgroup analysis for PFS and OS showed no statistically significant difference in relation to patient‘s age, FIGO stage, laparoscopic predictive index value, surgical complexity score. Conclusion Our results show that NGR at IDS is associated with the same survival outcomes compared to millimetric residual disease at PDS. In addition, neither older age, nor FIGO stage, and tumour load are correlated with a reduction of survival, irrespectively to the treatment strategy. Research efforts to identify pre-treatment criteria of response to chemotherapy are encouraged to improve patient‘s treatment selection. Disclosure Nothing to disclose.

Purposes: The primary objective is to assess the long-term quality of life (QoL) and gastrointestinal well-being in patients with endometriosis (DIE) who underwent segmental resection (SR), through specific questionnaires focused on endometriosis and specific gastrointestinal evaluation. The secondary objectives are represented by the evaluation of peri-operative and post-operative outcomes of the procedure. Methods: This observational cohort study ENDO-RESECT (ClinicalTrials.gov ID: NCT03824054) reports all clinical data about women who underwent SR for DIE between October 2005 and November 2017. In the partof thestudy dedicated to the QoL assessment, the questionnaires adopted were the Endometriosis Health Profile (EHP30), the Psychological General Well-Being Index and the Hospital Anxiety and Depression Scale, the Gastrointestinal Well-being questionnaire and the Bristol Stool chart. Major post-surgical morbidity and obstetric outcomes were also collected. Results: 50 women (18% stage III and 82% stage IV rAFS) were considered for enrollment. EHP-30 interpretation demonstrated a significant improvement in all continuous variables, except for fertility concerns. The overall gastrointestinal QoL and most of the specific symptoms improved after surgery. Frequent bowel movements appeared in the 13% of the series not resulting in an impairment of general and gastrointestinal QoL. Constipation remained unchanged. Patients with depressive mood managed with laparoscopy, benefited the most from SR; moreover, patients with multinodular bowel localizations experienced a greater reduction in abdominal pain. Median FU after SR was 42.5months (range 12–157months). Only three (6%) cases of late major grade III complications were documented. The pregnancy rate was 50%. Conclusions: Improvement of general QoL and most of gastrointestinal symptoms was documented after SR.

The malignant transformation of endometriosis is a very uncommon event but can occur in 0.7% to 1% of all cases. Any histological type of tumor found in the endometrium might also occur in endometriosis. Most malignant tumors that originate from endometriosis are endometrioid adenocarcinomas and also clear-cell type carcinomas. On the other hand, sarcomas, especially endometrial stromal sarcoma (ESS), are extremely unusual representing 12% of all cases. ESS is an uncommon neoplasm and accounts for 0.2% of the uterine malignances. Malignant tumors arising from endometriosis can derive from the uterine wall as well as from extra-uterine sites. The most frequent extrauterine location is the ovary (78.7%), followed by the pelvic peritoneum (5.7%), the rectovaginal septum (4.3%), the colon (4.3%) and the vagina (2%), representing the majority of extragonadal sites. ESSs arising from the extrauterine and extraovarian endometriosis sites in the absence of a primary uterine lesion are extremely rare and the treatment options are not clear. Surgical debulking seems to be the best treatment. Adjuvant therapy, such as radiation, hormonal therapy and chemotherapy are not yet proven to be effective. Molecular target therapy could be a future possibility of treatment. A systematic review of English Medical Literature about incidence, treatment and prognosis of extrauterine ESS arising from endometriosis foci was performed. The selected articles on which this review is based are the following: 9 literature reviews, 8 retrospective studies, 7 case series, 1 prospective trial and 11 case reports.

The treatment of renal cell carcinoma (RCC) with cavoatrial involvement represents a major surgical challenge. To date, many surgical strategies have been proposed. However, general agreement on the best approach does not yet exist. Deep hypothermic circulatory arrest (DHCA) is the most commonly used method and allows complete tumor resection without increasing operative risk. Cardiopulmonary bypass (CPB) without circulatory arrest and methods using no CBP were also proposed, without a clear evidence of superiority of 1 technique over the others. Further studies are needed to evaluate the possible role of alternative techniques compared with deep hypothermic circulatory arrest.
