Evolving trends in the management of pelvic inflammatory disease (PID) during SARS-CoV-2 pandemic: A multicenter retrospective cohort study.

BACKGROUND AND AIM: Pelvic inflammatory disease (PID) is usually managed by conservative treatment, but in selected cases, especially in the presence of a tubo-ovarian abscess (TOA), surgical management is a recognized treatment option. We compared the trends in managing PID and short-term outcomes before and during the SARS-CoV-2 pandemic. METHODS: This is a retrospective study performed in three Italian gynecological centers. We included patients admitted to hospital with a diagnosis of PID. Demographic characteristics, management, time to diagnosis, and time to treatment were compared before versus during the SARS-CoV-2 pandemic. RESULTS: One hundred nineteen PID patients were screened, eighty-one before the SARS-CoV-2 pandemic, and thirty-eight after the onset. At admission, leukocytosis (median 19.73 vs. 13.99 WBC/mm3, p-value = 0.02) was significantly higher in patients who underwent surgery after the onset of the pandemic. TOA incidence was higher in patients who underwent surgery during the SARS-CoV-2 pandemic, but the difference did not reach statistically significance (p = 0.06). The proportion of patients treated with surgery dropped to 26.3% after the onset from 46% of patients before the onset of pandemic (p = 0.03). Furthermore, a higher percentage of emergency surgical procedures on day 0 of hospital admission were performed after the onset of the pandemic (50% vs. 13.1%, p = 0.01). CONCLUSIONS: In this retrospective cohort study, we found that the SARS-CoV-2 pandemic influenced the clinical presentation and management of PID in favor of conservative treatment. Patients who underwent surgery during the SARS-CoV-2 pandemic had higher inflammatory markers.

Major and minor complications in Veress needle (VN) and direct trocar insertion (DTI) for laparoscopic closed-entry techniques: an updated systematic review and meta-analysis.

OBJECTIVE: Direct insertion of the trocar is an alternative method to Veress needle insertion for the creation of pneumoperitoneum. We conducted a systematic review and meta-analysis to compare these two entry closed techniques. DATA SOURCE: A systematic review of the literature was done on PubMed, MEDLINE, Embase, Scopus, and EBSCO. METHODS: The literature search was constructed until May 01, 2022, around search terms for "Veress," "direct trocar," "needle," "insertion," and "laparoscopic ways of entry." This systematic review was reported according to the PRISMA Statement 2020. RESULTS: Sixteen controlled trials (RCTs) and 5 observational studies were included in the systematic review. We found no significant differences in the risk of major complication during the access manoeuvres between DTI and VN: bowel injuries (OR = 0.76, 95% CI: 0.24-2.36, P = 0.63), major vascular injuries (OR = 1.74, 95% CI 0.56-5.38, P = 0.34), port site hernia (OR = 2.41, 95% CI: 0.28-20.71, P = 0.42). DTI has a lower risk of minor complications such as subcutaneous emphysema (OR = 5.19 95% CI: 2.27-11.87, P < 0.0001), extraperitoneal insufflation (OR = 5.93 95% CI: 1.69-20.87, P = 0.006), omental emphysema (OR = 18.41, 95% CI: 7. 01-48.34, P < 0.00001), omental bleeding (OR = 2.32, 95% CI: 1.18-4.55, P = 0.01), and lower number of unsuccessful entry or insufflation attempts (OR = 2.25, 95% CI: 1.05-4.81, P = 0.04). No significant differences were found between the two groups in terms of time required to achieve complete insufflation (MD = - 15.53, 95% CI: - 91.32 to 60.27, P = 0.69), trocar site bleeding (OR = 0.66, 95% CI, 0.25-1.79, P = 0.42), and trocar site infection (OR = 1.19, 95% CI, 0.34-4.20, P = 0.78). CONCLUSION: There were no statistically significant differences in the risk of major complications during the access manoeuvres between DTI and VN. A lower number of minor complications were observed in DTI compared with those in Veress access.

Surgical outcomes of diaphragmatic resection during cytoreductive surgery for advanced gynecological ovarian neoplasia: A randomized single center clinical trial - DRAGON.

INTRODUCTION: Ovarian cancer (OC) represent nearly 4% of gynecologic malignancies and it is often diagnosed at advanced stage. Diaphragmatic surgery, a fundamental step of advanced stage ovarian cancer (ASOC) debulking surgery, is associated with a high post-operative complication incidence, which is supposedly reduced with thoracostomy tube placement. We assessed the role of intra-operative thoracostomy tube placement, as a prevention measure for post-operative complications, after diaphragmatic resection. METHODS: This was a single center prospective randomized trial. Ovarian cancer patients, who underwent mono-lateral diaphragmatic resection, were randomized 1:1 into two arms. Arm A included patients receiving intra-operative thoracostomy tube placement (TP); Arm B patients did not receive thoracostomy tube placement (NTP). After surgery, all patients underwent seriate chest x-ray and ultrasound to record thoracic complications. Statistical analysis included uni- and multivariable logistic regression model (proportional odds model). RESULTS: Three hundred seventy-one patients were screened and 88 patients were enrolled: 44 in arm A and B, respectively. No statistically significant differences for intra-operative (p = 0.291) and any grade of post-operative complication (p = 0.072) were detected, while 6.8% of patients in arm A and 22.7% in arm B experienced severe respiratory symptoms (p = 0.035); 18.2% of patients in arm A had a moderate/large pleural effusion versus 65.9% in arm B (p < 0.0001). At multivariable analysis, results confirmed that the NTP-group had a higher risk to receive post-operative thoracostomy tube placement due to pleural effusion than the TP-group (odds ratio [95% Confidence Interval] = 14.5 [3.7-57.4]). CONCLUSIONS: Thoracostomy intra-operative tube placement after diaphragmatic resection is effective to prevent post-operative thoracic complications. The extension of resection does not influence outcomes and the risk of post-operative thoracentesis or TP remain elevated.

Robotic Single-Port Platform in General, Urologic, and Gynecologic Surgeries: A Systematic Review of the Literature and Meta-analysis.

BACKGROUND: Robotic platforms have recently acquired progressive importance in different surgical fields, such as urology, gynecology, and general surgery. Through the years, new surgical robots have become available as single-port robotic platform. The study is aimed to value the single-port robotic platform characteristics in different surgical specialties. METHODS: The terms "LESS" OR "single port" OR "single site" AND "robot" OR "robotic" were systematically used to search the PubMed and Scopus databases. A total of 57 studies were considered eligible for the present review. The articles included were divided according to the surgical field in which the study was conducted: General surgery (29 articles), Gynecology (18 articles), Urology (10 articles). RESULTS: Most part of the articles showed the feasibility of robotic single-port surgical procedures and described advantages in terms of cosmetic, hospital stay, and in some series even cost reduction. A meta-analysis was conducted, showing a significant increment of complications using RSP if compared with SLPS and a trend (P = 0.008) when RSP was compared with LESS. The comparison of different techniques in terms of conversion to laparotomy did not show any significant difference. CONCLUSION: Robotic single port potentially furnishes an important surgical and post-operatory improvement; however, some limits still prolong the surgical time and complication rate.

Total laparoscopic hysterectomy for enlarged uteri: factors associated with the rate of conversion to open surgery.

A hysterectomy for enlarged uteri is considered a challenge for gynaecologic surgeons, due to the limit of exposure to surgical spaces. Our objective is to investigate the different variables that may have an impact on the risk of conversion to open surgery. This is a retrospective cohort study consisting of 133 women who were submitted to surgery for uterine fibroids and who underwent total hysterectomy by laparoscopic approach attempt. The median uterus weight was 622 grams (range 301-3882) and the median maximum diameter of the bigger fibroid was 74 mm (range 33-148). We registered 13 (9.8%) cases of conversion to laparotomy. Minor and major post-operative complications were recorded in 4 (3%) and in 4 (3%) cases, respectively. After multivariable analysis, the surgeon's experience (OR: 0.24; 95% CI: 0.06-0.94, p = .027) and a maximum diameter of the biggest fibroid ≥10 cm (4.7; 1.39-15.87; p = .046), but not the uterus weight were associated with the risk of conversion to open surgery. IMPACT STATEMENT What is already known on this subject? Laparoscopic procedures for enlarged uteri are well described in literature; however, the only parameters that have been studied for the success of a laparoscopic procedure have been the uterus weight and the surgeon's experience. What do the results of this study add? This study aimed to value all the possible variables related to the successful of laparoscopic procedures; in fact, we investigated not only the uterine weight, but in our multivariate analysis, the position of the fibroids, the trocar's setting, etc. were analysed. What are the implications of these findings for clinical practice and/or further research? This study reported novel data about the feasibility of laparoscopic hysterectomy for enlarged uteri. In opposition to the literature, the uterine weight is not a predictive value for laparotomic conversion. Moreover, we discussed the possible reasons of our novel findings. It opens new perspective to create a predictive value of laparoscopic feasibility for the different types of enlarged uteri.

Identification of high-grade serous ovarian cancer miRNA species associated with survival and drug response in patients receiving neoadjuvant chemotherapy: a retrospective longitudinal analysis using matched tumor biopsies.

BACKGROUND: Neoadjuvant chemotherapy (NACT) has been recognized as a reliable therapeutic strategy in patients with unresectable advanced epithelial ovarian cancer (EOC). The molecular events leading to platinum (Pt) response in NACT settings have hitherto not been explored. In the present work, longitudinal changes of miRNA expression profile were investigated to identify miRNA families with prognostic role in high-grade serous EOC patients who received the NACT regimen. PATIENTS AND METHODS: One hundred sixty-four matched tumor biopsies taken at initial laparoscopic evaluation and at interval-debulking surgery (IDS) after four courses of Pt-based therapy were selected from 82 stage IIIC-IV high-grade serous-EOC patients that were judged unsuitable for complete primary debulking and subjected the NACT protocol. miRNA profiling by microarray, real-time PCR and immuno-histochemical staining for Smad2 phosphorylation (P-Smad2) were used for data analysis. RESULTS: Analysis revealed that 369 miRNAs were differentially expressed in matched biopsies (referred to as DEMs). DEMs were not scattered across the genome, but clustered into families: miR-199, let-7, miR-30, miR-181 and miR-29. Multivariate analysis showed that miR-199a-3p, miR-199a-5p, miR-181a-5p and let-7g-5p associated with overall and progression-free survival (P < 0.05); miR-199a-3p, miR-199a-5p and miR-181a-5p associated with residual tumor volume and Pt-free interval (P < 0.05). Immuno-histochemical staining confirmed an enrichment of P-Smad2, a marker of transforming growth factor-ß activation, in tumors from patients with shorter PFS and OS, and with high levels of expression of miR-181a-5p (P < 0.05). Kaplan-Meier curves plotting concomitant expression of P-Smad2 and miR-181a-5p show significant differences in PFS and OS compared with those depicting the expression of each biomarker alone (P < 0.001). CONCLUSIONS: This study describes several miRNA families with a prognostic role in the NACT setting. It also confirms that concomitant analysis of P-Smad2 and miR-181a-5p in surgical samples may be capable of identifying those ovarian cancer patients with poor outcome and little chance of response to Pt-based NACT.

A laparoscopic risk-adjusted model to predict major complications after primary debulking surgery in ovarian cancer: A single-institution assessment.

OBJECTIVE: To develop and validate a simple adjusted laparoscopic score to predict major postoperative complications after primary debulking surgery (PDS) in advanced epithelial ovarian cancer (AEOC). METHODS: From January 2006 to June 2015, preoperative, intraoperative, and post-operative outcome data from patients undergoing staging laparoscopy (S-LPS) before receiving PDS (n=555) were prospectively collected in an electronic database and retrospectively analyzed. Major complications were defined as levels 3 to 5 of MSKCC classification. On the basis of a multivariate regression model, the score was developed using a random two-thirds of the population (n=370) and was validated on the remaining one-third patients (n=185). RESULTS: Major complication rate was 18.3% (102/555). Significant predictors included in the scoring system were: poor performance status, presence of ascites (>500cm(3)), CA125 serum level (>1000U/ml), and high laparoscopic tumor load (predictive index value, PIV ≥8). The mean risk of developing major postoperative complications was 3.7% in patients with score 0 to 2, 13.2% in patients with score 3 to 5, 37.1% in patients with score 6 to 8. In the validation population, the predicted risk of major complications was 17.8% (33/185) versus a 16.7% (31/185) observed risk (C-statistic index=0.790). CONCLUSION: This new score may accurately predict a patient's postoperative outcome. Early identification of high-risk patients could help the surgeon to adopt tailored strategies on individual basis.

Minimally invasive versus standard laparotomic interval debulking surgery in ovarian neoplasm: A single-institution retrospective case-control study.

OBJECTIVE: To further investigate the role of MIS comparing patients submitted to MI-IDS with a balanced population treated by standard laparotomy. METHODS: The investigational arm (Cases) includes 30 AEOC patients treated with MI-IDS. The Control arm included a consecutive series of 65 AEOC patients submitted to laparotomic IDS. Inclusion criteria were: age>18years, histologically proven EOC, clinical complete/partial response after NACT, and ECOG PS <2. Preoperative clinical data, perioperative and oncological outcomes were analyzed. General Well-Being Schedule (GWBS) was administered to evaluate quality of life before and after surgery. RESULTS: Both groups were well-balanced. A higher percentage of women among Cases received bevacizumab-containing NACT compared with Controls. No statistical differences were registered in terms of surgical procedures and residual tumor. A significantly longer median OT in Cases was counterbalanced by more favorable EBL and median length of stay and TTC. No statistically significant differences were registered in terms of postoperative complications. Cases showed a 6months longer PFS compared to Controls. However, in multivariate analysis only the administration of Bevacizumab and a shorter TTC were independently associated with a longer PFS. Regarding QoL, no statistically significant differences were registered in Cases between pre- and postoperative GWBS score. Differently from Controls where this difference was statistically significant and a more intense distress were recorded. CONCLUSIONS: Minimally invasive approach could represent an advantageous alternative surgical way to perform interval debulking surgery in this specific subset of patients, with no impact on PFS. Based on these findings a randomized clinical trial is now under evaluation in our Institution.

Definition of a dynamic laparoscopic model for the prediction of incomplete cytoreduction in advanced epithelial ovarian cancer: proof of a concept.

OBJECTIVE: To develop an updated laparoscopy-based model to predict incomplete cytoreduction (RT>0) in advanced epithelial ovarian cancer (AEOC), after the introduction of upper abdominal surgery (UAS). PATIENTS AND METHODS: The presence of omental cake, peritoneal extensive carcinomatosis, diaphragmatic confluent carcinomatosis, bowel infiltration, stomach and/or spleen and/or lesser omentum infiltration, and superficial liver metastases was evaluated by staging laparoscopy (S-LPS) in a consecutive series of 234 women with newly diagnosed AEOC, receiving laparotomic PDS after S-LPS. Parameters showing a specificity≥75%, PPV≥50%, and NPV≥50% received 1 point score, with an additional one point in the presence of an accuracy of ≥60% in predicting incomplete cytoreduction. The overall discriminating performance of the LPS-PI was finally estimated by ROC curve analysis. RESULTS: No-gross residual disease at PDS was achieved in 135 cases (57.5%). Among them, UAS was required in 72 cases (53.3%) for a total of 112 procedures, and around 25% of these patients received bowel resection, excluding recto-sigmoid resection. We observed a very high overall agreement between S-LPS and laparotomic findings, which ranged from 74.7% for omental cake to 94.8% for stomach infiltration. At a LPS-PIV≥10 the chance of achieving complete PDS was 0, and the risk of unnecessary laparotomy was 33.2%. Discriminating performance of LPS-PI was very high (AUC=0.885). CONCLUSIONS: S-LPS is confirmed as an accurate tool in the prediction of complete PDS in women with AEOC. The updated LPS-PI showed improved discriminating performance, with a lower rate of inappropriate laparotomic explorations at the established cut-off value of 10.

Laparoscopic radical hysterectomy in cervical cancer as total mesometrial resection (L-TMMR): a multicentric experience.

OBJECTIVE: To analyze the feasibility of total mesometrial resection by laparoscopy (L-TMMR) in a multicentric series of early stage cervical cancer. METHOD: We prospectively evaluated a consecutive series of cervical cancer patients with pre-operative FIGO stages IA2-IB1 at the Catholic University in Rome and in Campobasso and the Charitè University in Berlin. All cases were assessed at pre-operative MRI scan and clinically confirmed by investigation under anesthesia, adhering strictly to the FIGO criteria. The surgical and post-surgical data were collected. RESULTS: 104 women with cervical cancer were admitted between July 2013 and August 2014 and among them 71 patients with pre-operative FIGO stages IA2-IB1 were treated with L-TMMR. One laparotomic conversion was registered. The median operative time was 260min (120-670min), estimated blood loss was 100cm(3) (25-900cm(3)), and the median length of hospital stay was 6days (2-26days). We observed 8 intra-operative complications including a vascular injury of the left internal iliac vein that caused conversion, 6 vesical injuries and 1 ureteral injury managed laparoscopically. Two vescico-vaginal fistula and one hemoperitoneum were observed as major post-operative complications (4.2%). CONCLUSION: L-TMMR can be safely performed in selected cervical cancer patients. Further larger prospective trials are needed to evaluate the oncological outcome of patients undergoing this surgical procedure.

Port-site hernia recurrence at previous 5-mm laparoscopic access: case report and review of literature.

Port-site hernia (PSH) of less than 10 mm is an exceptionally rare complication of minimally invasive surgery (MIS). To date, there have been no cases in the literature reporting recurrence of PSH from a 5 mm incision. We present the first case of PSH recurrence in a woman who underwent surgery for benign gynaecological pathology via a MIS approach. Her post-operative course was complicated by an episode of symptomatic hernia arising from a 5 mm accessory trocar which was surgically managed. A few months later she re-presented with the same symptoms and had a PSH recurrence of the same port-site. Two corrective surgeries employing different techniques were performed. The first episode was managed laparoscopically using interrupted stitches. On the other hand, the PSH recurrence was managed by placement of a mesh. Ultrasound played a crucial role in diagnostics, especially in the recurrent setting. Due to the complete absence of similar cases in the literature, the decision making around the management of a PSH recurrence from a 5 mm trocar site proved to be challenging. As MIS is the current standard of care, more cases are likely to occur, however despite the increasing number of surgical procedures performed via MIS, no established guidelines for managing such complications have been proposed. Trying to bridge this gap, we present the case report of the first case of PSH recurrence from a 5 mm accessory port and a review of the most significant literature available to date. We finally summarise the reported cases of PSH and the types of surgical repair conducted to highlight the absence of a standard of care.

Primary flap closure of perineal defects to avoid empty pelvis syndrome after pelvic exenteration in gynecologic malignancies: An old question to explore a new answer.

Pelvic exenteration (PE) is a radical oncological surgical procedure proposed in patients with recurrent or persistent gynecological cancers. The radical alteration of pelvic anatomy and of pelvic floor integrity can cause major postoperative complications. Fortunately, PE can be combined with reconstructive procedures to decrease complications and functional and support problems of pelvic floor, reducing morbility and mortality and increasing quality of life. Many options for reconstructive surgery have been described, especially a wide spectrum of surgical flaps. Different selection criteria have been proposed to select patients for primary perineal defect flap closure without achieving any strict indication of the best option. The aim of this review is to focus on technical aspects and the advantages and disadvantages of each technique, providing an overview of those most frequently used for the treatment of pelvic floor defects after PE. Flaps based on the deep inferior epigastric artery, especially vertical rectus abdominis musculocutaneous (VRAM) flaps, and gracilis flaps, based on the gracilis muscle, are the most common reconstructive techniques used for pelvic floor and vaginal reconstruction. In our opinion, reconstructive surgery may be considered in case of total PE or type II/III PE and in patients submitted to prior pelvic irradiation. VRAM could be used to close extended defects at the time of PE, while gracilis flaps can be used in case of VRAM complications. Fortunately, numerous choices for reconstructive surgery have been devised. As these techniques continue to evolve, it is advisable to adopt an integrated, multi-disciplinary approach within a tertiary medical center.

Simple hysterectomy versus radical hysterectomy in early-stage cervical cancer: A systematic review and meta-analysis.

BACKGROUND: This systematic review (SR) and meta-analysis aims to compare the surgery-related results and oncological outcomes between SH and RH in patients with early-stage cervical cancer. METHOD: We systematically searched databases including PubMed, Embase and Cochrane to collect studies that compared oncological and surgery-related outcomes between SH and RH groups in patients with stage IA2 and IB1 cervical cancer. A random-effect model calculated the weighted average difference of each primary outcome via Review Manager V.5.4. RESULT: Seven studies comprising 6977 patients were included into our study. For oncological outcomes, we found no statistical difference in recurrence rate [OR = 0.88; 95% CI (0.50, 1.57); P = 0.68] and Overall Survival (OS) [OR = 1.23; 95% CI (0.69, 2.19), P = 0.48]. No difference was detected in the prevalence of positive LVSI and lymph nodes metastasis between the two groups. Concerning surgery-related outcomes, the comprehensive effects revealed that the bladder injury [OR = 0.28; 95% CI (0.08, 0.94), P = 0.04] and bladder disfunction [OR = 0.10; 95% CI (0.02, 0.53), P = 0.007] of the RH group were higher compared to the SH group. CONCLUSION: This meta-analysis suggested there are no significant differences in terms of both recurrence rate and overall survival among patients with stage IA2-IB1 cervical cancer undergoing SH or RH, while the SH group has better surgery-related outcomes. These data confirm the need to narrow the indication for RH in early-stage cervical cancer.

Timing and pattern of recurrence in ovarian cancer patients with high tumor dissemination treated with primary debulking surgery versus neoadjuvant chemotherapy.

PURPOSE: To compare the timing and pattern of recurrence in patients with advanced ovarian cancer (AOC) receiving primary debulking surgery (PDS) versus neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS). METHODS: We retrospectively evaluated a consecutive series of 175 stage IIIC-IV epithelial ovarian cancer patients, with diffuse peritoneal carcinomatosis documented at initial surgical exploration. Forty patients received complete PDS, and the remaining 135 were treated with NACT followed by IDS with absent residual tumor after surgery. RESULTS: No differences were observed in the distribution of clinical pathological characteristics at the time of diagnosis between the two groups. The median follow-up was 31 months (range 9-150 months). We observed 20 (50.0%) recurrences in the PDS group compared to 103 (76.3%) in the IDS group (p = 0.001). Duration of primary platinum-free interval (PFI) was shorter in IDS compared to PDS group (13 vs. 21 months, respectively; p = 0.014). A significantly higher percentage of patients in the IDS group experienced platinum-resistant recurrences (35.9 vs. 5.0%; p = 0.006) and carcinomatosis at the time of relapse (57.3 vs. 20.0%; p = 0.0021). Finally, in women with platinum-sensitive recurrence, we observed a shorter secondary PFI in the IDS compared to PDS group (p = 0.006). CONCLUSIONS: We documented a better behavior of recurrent disease in AOC patients with diffuse peritoneal carcinomatosis treated with complete PDS compared to women submitted to NACT followed by IDS with no residual tumor after surgery.

Robotic single-site hysterectomy (RSS-H) vs. laparoendoscopic single-site hysterectomy (LESS-H) in early endometrial cancer: a double-institution case-control study.

OBJECTIVE: To report our experience with single-site robotic platform for IS3000 "Da Vinci" Si Surgical System to perform robotic single site hysterectomy (RSS-H), and to compare peri-operative results with a historical series of laparoendoscopic single site hysterectomies (LESS-H). METHODS: This is a retrospective case-control study, performed at the Gynecologic Oncologic Unit, National Cancer Institute "Regina Elena", Rome, and at the Gynecologic Oncologic Unit, Catholic University of the Sacred Heart, Rome, Italy between December 2011 and January 2013. RESULTS: 19 women underwent RSS-H (cases) and 38 patients were submitted to LESS-H (controls) for early endometrial cancer. Pre-surgical procedures (port placement and docking) required a median time of 8 min in the RSS-H group and a median time of 2 min in the LESS-H group (p=0.0001). The median estimated blood loss was 75 ml in the cases and 30 ml in the controls (p=0.005). The median operative time, calculated from the beginning of intraperitoneal procedures to the skin closure, was 90 min in the cases and 107 ml in the controls (p=ns). The median time to discharge from the hospital was postoperative day two for both techniques. CONCLUSIONS: The few differences we registered do not seem clinically relevant, thus making the two procedures comparable.

Ovarian cancer patients with localized relapse: clinical outcome and prognostic factors.

OBJECTIVE: We evaluated the clinical outcome and prognostic factors for post-relapse survival (PRS) in a large retrospective series of ovarian cancer patients with localized relapse. PATIENTS AND METHODS: The following radiological inclusion criteria were adopted: relapse in single anatomic site and ≤ 3 nodules. All cases were followed for at least 24 months after recurrent disease. RESULTS: Two hundred twenty ovarian cancer patients met the inclusion criteria. Serous histotype and G3 tumors were observed in 173 (78.6%) and 151 (77.4%) cases, respectively. All women received platinum-based first-line chemotherapy. Overall, the median follow-up was 46 (8-249) months, and platinum-resistant relapse was documented in 51 women (23.2%). Eighty-one patients (36.8%) recurred in the peritoneum (LPeR), 76 patients (34.5%) in the abdominal lymph nodes (LLNR), and 63 patients (28.7%) in parenchymal organs (LPaR); 142 patients (64.5%) recurred with a single nodule; and 78 patients (35.5%) recurred with 2-3 nodules. Secondary cytoreductive surgery (SCS) was attempted in 73 cases (33.2%), and complete debulking was achieved in all patients. On multivariate analysis, platinum-free interval (PFI, χ(2)=13.457, p value=0.001), complete SCS (median PRS, 69 months vs 25 months, p=0.001), anatomic site of relapse (median PRS, 41months in LPeRs, 63 months in LLNRs and 24 months in LPaRs, p=0.001), and number of nodules (median PRS, 58months in patients with one nodule, 24months in patients with 2-3 nodules, p=0.001) were identified as predictors of PRS. CONCLUSIONS: Beside the duration of PFI, the complete SCS, the anatomic site of relapse, and the number of nodules were independent prognostic factor for duration of PRS.

Introduction of staging laparoscopy in the management of advanced epithelial ovarian, tubal and peritoneal cancer: impact on prognosis in a single institution experience.

OBJECTIVE: To evaluate the prognostic impact of routinely use of staging laparoscopy (S-LPS) in patients with primary advanced epithelial ovarian cancer (AEOC). METHODS: All women were submitted to S-LPS before receiving primary debulking surgery (PDS) or neoadjuvant treatment (NACT). The surgical and survival outcome were evaluated by univariate and multivariate analysis. RESULTS: Among 300 consecutive patients submitted to S-LPS no complications related to the surgical procedure were registered. The laparoscopic evaluation showed that almost half of the patients (46.3%) had a high tumor load. One-hundred forty-eight (49.3%) women were considered suitable for PDS and the remaining 152 (50.7%) were submitted to NACT. The percentages of complete (residual tumor, RT=0) and optimal (RT<1cm) cytoreduction of PDS and interval debulking surgery (IDS) were 62.1% and 57.5%, 22.5% and 27.7%, respectively, p=0.07. The post-operative complications of NACT/IDS group were lower than PDS group (p=0.01). The median progression free survival in women with RT=0 at PDS was 25 months (95% CI, 15.1-34.8), which was statistically significant longer than in all other patients, irrespective of the type of treatment they received (p=0.0001). At multivariate analysis, residual disease (p=0.011) and performance status (p=0.016) maintained an independent association with the PFS. CONCLUSIONS: Including S-LPS in a tertiary referral center for the management AEOC does not appear to have a negative impact in terms of survival and it may be helpful to individualize the treatment avoiding unnecessary laparotomies and surgical complications.

Minimally invasive pelvic exenteration for gynaecological malignancies: the challenge of patients' selection.

Pelvic exenteration is a radical procedure representing a salvage option in patients with recurrent or persistent gynaecological malignancies. It can be performed with an open or minimally invasive approach. Different studies have demonstrated optimal peri-operative outcomes of minimally invasive pelvic exenteration with no survival difference when compared with an open approach. In this article, we discuss the importance and the challenge of patient selection for pelvic exenteration and more specifically for minimally invasive pelvic exenteration.

Three-dimensional vision versus two-dimensional vision on laparoscopic performance of trainee surgeons: a systematic review and meta-analysis.

Laparoscopic surgery underwent great improvements during the last few years. This review aims to compare the performance of Trainee Surgeons using 2D versus 3D/4 K laparoscopy. A systematic review of the literature was done on Pubmed, Embase, Cochrane's Library and Scopus. The following words and key phrases have been searched: "Two-dimensional vision", "Three-dimensional vision", "2D and 3D laparoscopy", "Trainee surgeons". This systematic review was reported according to the PRISMA statement 2020. PROSPERO registration No. CRD42022328045. Twenty-two randomized controlled trials (RCTs) and two observational studies were included in the systematic review. Two trials were carried out in a clinical setting, and twenty-two trials were performed in a simulated setting. In studies involving the use of a box trainer, the number of errors in the 2D laparoscopic group was significantly higher than in the 3D laparoscopic group during the performance of FLS skill tasks: peg transfer (MD: -0.82; 95% CI - 1.17 to - 0.47; p < 0.00001), cutting (MD: - 1.09; 95% CI - 1.50 to - 0.69 p < 0.00001), suturing (MD: - 0.48; 95% CI - 0.83 to - 0.13 p = 0.007), However, in clinical studies, there was no significant difference in the time taken for laparoscopic total hysterectomy (MD: 8.71; 95% CI - 13.55 to 30.98; p = 0.44) and vaginal cuff closure (MD: 2.00; 95% CI - 0.72 to - 4.72; p = 0.15) between 2D group and 3D group. 3D laparoscopy facilitates learning for novice surgeons and shows improvements in their laparoscopic performance.

Influence of uterine manipulator on oncological outcome in minimally invasive surgery of endometrial cancer: A systematic review and meta-analysis.

AIM: The endoscopic approach for early-stage endometrial cancer (EC) treatment is considered gold standard. Some authors expressed their concern regarding uterine manipulator (UM) as a risk factor for tumor spillage and dissemination allowing peritoneal or lympho-vascular spaces invasion (LVSI). This meta-analysis aimed to evaluate the effect of UM on the presence of LVSI, recurrence rate and presence of atypical or malignant peritoneal cytology in patients with endometrial cancer. METHODS: We searched electronic databases including PubMed, MEDLINE, Embase, Scopus, EBSCO, Google Scholar, and ClinicalTrials.gov. The pooled results were used to evaluate the association between the use of UM and oncological outcomes. This systematic review was reported according to PRISMA statement 2020. Statistical meta-analysis was performed using Review Manager software. RESULTS: This systematic review included 18 studies (3 prospective studies, 13 retrospective studies, and 2 RCT). The pooled results showed no significant difference (RR: 0.86, 95% CI, 0.69 to 1.08) in the incidence of LVSI between manipulated hysterectomy and total abdominal hysterectomy (TAH) and between UM group and non-UM group in minimally invasive surgery (RR: 1.18, 95% CI, 0.76 to 1.85), no significant difference in the rate of recurrence (RR: 1.11, 95% CI, 0.71 to 1.74), in the incidence of positive peritoneal cytology between manipulated and non-manipulated hysterectomies in minimally invasive surgery (RR: 1.89, 95% CI, 0.74 to 4.83) and before and after the use of uterine manipulator (RR: 1.21, 95% CI, 0.68 to 2.16). We found a positive association between malignant cytology and hysterectomies in which a uterine manipulator had been used in a sub-group analysis where LH/LAVH were compared to TAH. (RR = 2.26, 95% CI, 1.08-4.71. P = 0.03). CONCLUSIONS: This meta-analysis supports that the use of uterine manipulator for minimally invasive treatment of endometrial cancer does not increase the rate of recurrence and LVSI. Therefore, the opportunity of any other studies on its use in endometrial cancer women should be questioned.
