Background: Ovarian cysts, common in women of reproductive age, often require surgical intervention, with minimally invasive laparoscopic surgery becoming the preferred method due to its reduced complications and faster recovery. Despite its benefits, challenges such as instrument collisions and operational difficulties limit the use of single- or two-port approaches. The purpose of this study was to evaluate the feasibility of laparoscopic adnexa surgery using an articulating laparoscopic instrument, which offers flexible and ergonomic movements similar to robotic systems. Methods: This multicenter prospective observational study was conducted in South Korea and Taiwan. The electronic medical records of patients who underwent laparoscopic adnexectomy using the articulating laparoscopic instrument (ArtiSential®, LIVSMED Inc., Seongnam-si, South Korea) between October 2022 and September 2023 were analyzed. Data on patient demographics, operative and pathologic data were collected prospectively. Results: A total of 66 patients underwent laparoscopic adnexal surgery using the articulating instrument. The median age of the patients was 43 (range, 23–76) years, and the median body mass index (BMI) was 22.5 (range, 17.1–43.4) kg/m2. Thirty-five (53.0%) patients underwent oophorectomy or salpingectomy, while 31 (47.0%) underwent cystectomy of the ovary or fallopian tube. The final pathology after surgery was benign in 61 patients (92.4%), borderline in 3 patients (4.5%), and malignant in 2 patients (3.0%). During surgery, pelvic adhesions were found in 13 patients (19.7%) and adhesiolysis was performed. The median total operation time was 53.5 (range, 26–174) minutes, and median estimated blood loss (EBL) was 50 (range, 10–200) mL. Median length of hospital stay was 1 (range, 0–3) days. Only two patients experienced a postoperative complication, which was trocar site wound dehiscence in both cases. Conclusions: The results of this study demonstrated the feasibility of using the articulating laparoscopic instrument during laparoscopic adnexectomy.

Background: Epithelial ovarian cancer is an aggressive malignancy with poor prognosis despite advances in multimodal treatment. The systemic immune-inflammation index (SII) has emerged as a prognostic biomarker in various cancers; however, the impact of surgery-induced inflammatory changes remains unclear. Methods: This study evaluated the prognostic significance of postoperative changes in SII among patients with epithelial ovarian cancer undergoing primary surgery. Data from 374 patients treated at Samsung Medical Center and Kangbuk Samsung Hospital between 2016 and 2021 were retrospectively reviewed. SII was calculated from complete blood counts obtained within one month before surgery and on postoperative day 1. The percentage change in SII was analyzed, and the optimal cutoff was determined using receiver operating characteristic curve analysis. Survival outcomes were assessed using Kaplan–Meier and multivariable Cox regression models. Results: Patients with a postoperative SII increase > 98.4% (Group 2) had significantly poorer overall (HR = 1.86, p = 0.009) and progression-free survival (HR = 1.30, p = 0.112) compared with those with smaller changes (Group 1). Discussion: High-grade histology, serous subtype, and greater intraoperative blood loss were associated with higher postoperative SII. A marked postoperative increase in SII independently predicted poor survival, suggesting that dynamic inflammatory responses rather than static baseline levels provide additional prognostic information. Conclusions: Perioperative SII monitoring, easily obtainable from routine blood tests, may help identify high-risk patients who could benefit from intensified surveillance or adjuvant treatment. Prospective multicenter studies are warranted to validate these findings and explore whether perioperative modulation of systemic inflammation can improve outcomes.

A bstract: Background/Objectives: Single-port access (SPA) laparoscopic surgery has gained popularity due to its cosmetic benefits and reduced postoperative pain. However, concerns persist regarding the increased risk of adhesions due to the larger umbilical incision. This study aims to contribute to personalized medicine by evaluating the effectiveness of applying an anti-adhesive agent (Guardix SG®, HanmiPharmaceutical Co., Ltd., Seoul, Korea) at the umbilical incision and identifying patient-specific risk factors for adhesion formation in SPA laparoscopic surgeries. Methods: In this randomized prospective study, 55 female patients with benign gynecological conditions were enrolled. Participants were randomly assigned to either an intervention group, which received the anti-adhesive agent at both the surgical and umbilical sites, or a control group, which received it only at the surgical site. Participants returned for outpatient visits 1–3 months post-surgery to assess incision site complications, including adhesions. Results: The overall adhesion rate was 10.9%, with 13.3% in the control group and 8% in the intervention group, though the difference was not statistically significant (p = 0.678). Infection rates were 6.7% in the control group and 4% in the intervention group; however, there was no significant difference in complications. Logistic regression identified pre-existing adhesions as a significant risk factor (p = 0.0379; OR = 6.909). Conclusions: Although the adhesion barrier showed a trend toward reducing umbilical adhesions, the difference was not statistically significant. The application of the adhesion barrier did not influence incision site complications, confirming its safety. Our findings highlight the need for personalized approaches to adhesion prevention, considering individual patient characteristics and risk factors. Further larger studies are necessary to explore adhesion prevention in a more personalized manner for individual patients in this context.

Background and Objectives: The therapeutic effect of para-aortic lymphadenectomy in patients with clinically para-aortic node-negative diseases remains controversial. In this study, we investigated whether combined pelvic and para-aortic lymphadenectomy has a survival benefit compared with pelvic lymphadenectomy alone in patients with clinically FIGO stage IIIC1 high-grade endometrial cancer. Materials and Methods: We retrospectively reviewed patients with clinically FIGO stage IIIC1 high-grade endometrial cancer in the period between January 2000 and December 2020 at two tertiary centers. The patients were stratified according to type of lymphadenectomy and subgroup analyses performed. Kaplan–Meier analysis and a Cox proportional-hazards model were used to evaluate survival outcomes. Results: A total of 56 patients were identified. Of these patients, 18 underwent pelvic lymphadenectomy alone and 38 underwent combined pelvic and para-aortic lymphadenectomy. After staging surgery, 34 (60.7%) patients had pathologically confirmed lymph node metastases. Within a median follow-up of 57.5 months, there were no significant differences in recurrence-free survival (RFS) and overall survival (OS) between the two groups. In subgroup analyses, the node- and lymphovascular space invasion (LVSI)-positive patients characterized by grade 3 endometrioid histologic type (p = 0.010) or negative peritoneal washing cytology (p = 0.035) had an RFS benefit from combined pelvic and para-aortic lymphadenectomy. Conclusions: The addition of para-aortic lymphadenectomy to pelvic lymphadenectomy did not improve survival in patients with clinically FIGO IIIC1 endometrial cancer. However, para-aortic lymphadenectomy may have RFS benefit for patients with grade 3 endometrioid histologic type and positive LVSI.

Background/Objectives: To assess the impact of the 2023 FIGO staging revision on stage distribution, survival outcomes, and prognostic performance in endometrial cancer compared to the 2009 system. Methods: This retrospective cohort study analyzed 2969 patients with FIGO 2009 stage I–III endometrial cancer diagnosed at Samsung Medical Center (1994–2023). Patients were reclassified per the 2023 FIGO system. Stage migration, progression-free survival (PFS), and overall survival (OS) were evaluated. Prognostic performance was compared using the Akaike information criterion (AIC), Bayesian information criterion (BIC), concordance index (C-index), and area under the receiver operating characteristic curve (AUC). Results: Stage migration occurred in 20.2% of patients, with 98.3% involving upstaging from FIGO 2009 stage I, largely due to the inclusion of aggressive histology, p53 abnormality, and substantial lymphovascular space invasion (LVSI). The proportion of stage I tumors decreased from 81.5% to 65.2%, while stage II increased to 21.9%, including 14.8% newly classified as stage IIC. Patients remaining in stage I showed favorable outcomes (5-year PFS: 95.3%, OS: 98.5%), whereas those upstaged—especially to stage IIC—had significantly worse outcomes (5-year PFS: 76.5%, OS: 83.1%). Tumors with p53 abnormalities had poorer survival (PFS: 70.8%, OS: 76.6%). The 2023 FIGO system outperformed the 2009 system in prognostic discrimination across all metrics. Conclusions: The FIGO 2023 staging revision improves prognostic accuracy in endometrial cancer by integrating histopathologic and molecular risk factors. These refinements enhance risk stratification and may support more individualized treatment strategies.
