Evaluation of Ovarian Reserve and Recurrence Rate After DWLS Diode Laser Ovarian Endometrioma Vaporization (OMAlaser): A Prospective, Single-arm, Multicenter, Clinical Trial.

STUDY OBJECTIVE: To evaluate the effectiveness of the Dual Wavelength Laser System (DWLS) diode laser on the treatment of ovarian endometrioma (OMA), with ablation and vaporization of the cystic capsule without performing the stripping technique, in terms of ovarian reserve and recurrence rate. DESIGN: Prospective, Single-arm, Multicenter, Clinical Trial SETTING: Multicenter University Hospital. PATIENTS: Seventy patients with symptomatic OMA. INTERVENTIONS: Patients underwent surgery for primary unilateral or bilateral symptomatic OMA treated with DWLS diode laser vaporization. Following surgical intervention, patients were enrolled in a 12 months surveillance protocol featuring regular clinical assessments aimed at detecting ovarian reserve, pregnancy rate and any recurrence of the cyst and/or symptomatic relapse. MEASUREMENTS AND MAIN RESULTS: Antimullerian hormone (AMH) levels at the 3-month follow-up exhibited a significant difference from the baseline (p=0.034), demonstrating a return to nearly presurgical values in the subsequent months. Antral follicle count (AFC) of the operated ovary showed a significant increase after treatment at the 6-month and 12-month follow-up (p=0.005 and p=0.002, respectively). Pregnancies were documented in 48.3% (14/29) of infertile patients who underwent treatment. OMA recurrence was observed in 4 patients (5.7%) at 12 months. No patient exhibited a significant relapse of the analyzed symptoms compared to baseline values. CONCLUSION: The findings of this study propose that DWLS diode laser presents a good option for treating OMA, demonstrating minimal impact on the surrounding healthy ovarian tissue, favorable pregnancy rate, coupled with low recurrence rates.

Cumulative Sum Analysis of Learning Curve Process for Vaginal Natural Orifice Transluminal Endoscopic Surgery Hysterectomy.

STUDY OBJECTIVE: This study aimed to evaluate the learning curve of vaginal natural orifice transuminal endoscopic surgery (vNOTES) hysterectomy in expert minimal invasive and vaginal surgery team. DESIGN: This is a cohort study on a retrospective analysis. SETTING: Department of Obstetrics and Gynecology of Cannizzaro Hospital in Catania Italy. PATIENTS: First 50 women underwent vNOTES hysterectomy between February 2021 and February 2022. INTERVENTION: vNOTES hysterectomy performed by a team with optimal skills in laparoscopic and vaginal surgery. MEASUREMENT AND MAIN RESULTS: Primary outcome was surgical time. Secondary outcomes were intraoperative and postoperative complications, length of hospitalization, and first 24-hour postoperative pain. All patients underwent hysterectomy for benign indications: 27 fibromatosis, 13 metrorrhagia, and 10 precancerous. Concomitant procedures have been bilateral adnexectomy in 35 cases and bilateral salpingectomy in 15 cases. The median age was 51 years (range, 42-64). Median body mass index was 26 kg/m2 (range, 21-42). The median operative time was 75 minutes (range, 40-110). The median hospital stay was 2 days (range, 1-4). There was 1 intraoperative adverse event (bladder lesion) and 1 postoperative grade 3 complication (hemoperitoneum). The median visual analog scale score for pain assessment during the first 24 hours after surgery was 3 (range, 1-6). The experience in our surgical center with the first 25 vNOTES hysterectomies showed an accumulation of initial experience in the first 5 cases with stable operating time and a gradual reduction of mean operating time in the subsequent 17 surgeries. The learning curve plotted by cumulative sum analysis shows 3 phases: phase 1 of competence (cases 1-5), phase 2 of proficiency (cases 6-26), and phase 3 of mastering the procedure (after the 31st case) with the management of more complex cases. CONCLUSION: vNOTES hysterectomy is a feasible and reproducible approach for benign indications with a short learning curve and low rate of perioperative complications. For a team skilled in minimally invasive surgery, 5 cases are required to rich competence and 25 to rich proficiency in vNOTES hysterectomy. Mastering phase, with the introduction of more complex cases, should be addressed after 30 surgeries.

Prognostic factors and surgical treatment in vulvar carcinoma: Single center experience.

AIM: Vulvar carcinoma represents 3-5% of all female genital cancers; the main surgical treatment is radical vulvectomy and inguinal lymphadenectomy. The aim of this study is to analyze prognostic factors in the patients underwent to primary surgery for vulvar carcinoma. METHODS: One hundred and eighteen cases of vulvar carcinoma underwent surgery between 2006 and 2016 at Operative Unit of Gynecology and Obstetrics of Cannizzaro Hospital (Catania, Italy) were retrospective analyzed. Risk factors for relapse (age, tumor size, FIGO stage, type of surgery, lymphadenectomy, margins status, metastatic nodes and radiotherapy) were evaluated by logistic regression. Univariate analysis of prognostic factors (age, tumor size, FIGO stage, metastatic inguinal nodes and type of surgery) was obtained by Cox proportional hazard model. Overall survival was calculated by Kaplan-Meier curves either for the entire population and for comparison between positive and negative variables (margin status, nodes and radiotherapy) with log-rank test to determine significance. Statistical significance was reached for P < 0.05. RESULTS: Type of surgery (radical local excision vs. radical vulvectomy) and positive inguinal nodes were identified as risk factors for relapse. Positive inguinal nodes and positive margins were identified as prognostic factors either for overall survival and disease specific survival; tumor size greater than 4 cm was identified as prognostic factors for overall survival. Overall survival was 38.4% and it was significantly higher in the patients with negative margins and nodes. CONCLUSIONS: Nodes status, resection margins, age and type of surgery represent prognostic factors have to be considered for adjuvant treatment in the patients affected from vulvar carcinoma.

Uterine Tumours Resembling Ovarian Sex-Cord Tumors: A Case Report and Review of the Literature.

Uterine tumors resembling ovarian sex-cord tumors (UTROSCT) are thought to develop from pluripotent uterine mesenchymal cells or endometrial stromal cells with secondary sex-cord differentiation. The patient was a 73-year-old postmenopausal woman who had abnormal vaginal bleeding, and she underwent a laparoscopic hysterectomy with bilateral salpingo-oophorectomy. The diagnosis was a case of UTROSCT. A scoping review of the UTROSCT case report present in the literature has been conducted, and 63 articles were found, of which 45 were considered for the 66 clinical cases examined. At the time of diagnosis, six metastatic localizations were found in 59 patients undergoing demolitive surgery (10.2%). Recurrences were diagnosed in 13/59 (22%) patients with multiple locations. A molecular study was performed in 18/66 cases (27.3%) and genetic alterations were found in 10/18 (55.6%) patients. UTROSCTs are considered rare uterine tumors, typically with a favorable prognosis, and are generally considered to have a good prognosis. But, from the review done, they may already manifest themselves at advanced stages, with the possibility of recurrences even at a distance. It would, therefore, be important to be able to define the most aggressive forms and, perhaps, molecular investigation with sequencing could help identify patients most at risk.

Evaluation of Surgical Outcomes of Abdominal Radical Hysterectomy and Total Laparoscopic Radical Hysterectomy for Cervical Cancer: A Retrospective Analysis of Data Collected before the LACC Trial.

Although a surgical approach is one of the key treatments for stages IA1-IIA2, results of the Laparoscopic Approach to Cervical Cancer (LACC) published in 2018 radically changed the field, since minimally invasive surgery was associated with a four-fold higher rate of recurrence and a six-fold higher rate of all-cause death compared to an open approach. We aimed to evaluate surgical outcomes of abdominal radical hysterectomy (ARH) and total laparoscopic radical hysterectomy (TLRH) for cervical cancer, including data collected before the LACC trial. In our retrospective analysis, operative time was significantly longer in TLRH compared to ARH (p < 0.0001), although this disadvantage could be considered balanced by lower intra-operative estimated blood loss in TLRH compared with ARH (p < 0.0001). In addition, we did not find significant differences for intra-operative (p = 0.0874) and post-operative complication rates (p = 0.0727) between ARH and TLRH. This was not likely to be influenced by age and Body Mass Index, since they were comparable in the two groups (p = 0.0798 and p = 0.4825, respectively). Finally, mean number of pelvic lymph nodes retrieved (p = 0.153) and nodal metastases (p = 0.774), as well as death rate (p = 0.5514) and recurrence rate (p = 0.1582) were comparable between the two groups. Future studies should be aimed at assessing whether different histology/grades of cervical cancer, as well as particular subpopulations, may have significantly different outcomes using minimally invasive surgery or laparotomy, with or without neoadjuvant chemotherapy.

Anastomotic Leakage after Colorectal Surgery in Ovarian Cancer: Drainage, Stoma Utility and Risk Factors.

Objective: to evaluate the incidence of anastomotic leakage (AL), risk factors and utility of drainage and stoma in patients undergoing intestinal surgery for ovarian cancer in a single institution and in a review of the literature. Methods: retrospective study that includes consecutive patients undergoing debulking surgery with en bloc pelvic resection with rectosigmoid colectomy for ovarian cancer between 1 November 2011 and 31 December 2021. Data regarding patient and tumour characteristics, surgical procedure, hospitalisation, complications and follow-up were recorded and analysed. The PubMed database was explored for recent publications on this topic. Results: Seventy-five patients were enrolled in the study. All anastomoses were performed at a distance of >6 cm from the anal margin, with negative leak tests and tension-free anastomosis. Diverting stoma were performed in just three patients (4%). At least one perianastomotic pelvic drain was positioned in 71 patients (94.7%) and was removed on average on postoperative day 7. Four patients (5.3%) experienced AL. In all cases, the drain content was not the only sign of complication, as the clinical signs were also highly suggestive. Just one patient received conservative treatment. Average postoperative hospitalisation was 14.6 days (SD: ±9.7). There were no deaths at 30 and 60 days after surgery. Between the AL and non-AL groups, statistically significant differences were observed for age, Charlson Comorbidity Index, length of the intestinal resection and fitness for chemotherapy at 30 days. In ovarian cancer, rectosigmoid resection is a standardised procedure with comparable results for AL, and risk factors for AL are discretely homogeneous. What is neither homogeneous nor standardised according to the literature is the use of stomas and/or drains. Conclusion: use in the future of protective stoma and/or intra-abdominal drains is to be explored in selected and standardised situations to verify their preventive role.
