RESUMO
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.
RESUMO
OBJECTIVE: BRCA mutational status is important in the management of ovarian cancer, but there is a lack of evidence supporting genetic testing in Asian populations. This study was performed to investigate the prevalence and prognostic outcomes of BRCA1/2 mutation and variant of unknown significance (VUS) in Korean patients diagnosed with epithelial ovarian cancer (EOC). METHODS: Among patients newly diagnosed with EOC between January 2007 and January 2017, those tested for germline BRCA1/2 mutation were studied, regardless of family history. Overall survival (OS) and progression-free survival (PFS) were compared between the patients with and without BRCA1/2 mutation and VUS. RESULTS: A total of 313 patients underwent BRCA testing: 88 patients had a BRCA1/2 mutation and 48 patients had a BRCA1/2 VUS (28.1% and 15.3%, respectively). There were no significant associations between BRCA1/2 mutation, BRCA1/2 wild-type, or BRCA1/2 VUS with age at diagnosis, histologic distribution, or residual disease status after primary cytoreductive surgery. BRCA1 mutation, including BRCA1 VUS, showed no difference in PFS or OS compared to BRCA1 wild-type. In contrast, BRCA2 mutation showed longer PFS than that of BRCA2 wild-type (P=0.04) or BRCA2 VUS (P=0.02). BRCA2 mutation, including BRCA2 VUS, did not show any difference in OS compared to BRCA2 wild-type. CONCLUSION: BRCA mutation and BRCA VUS had similar clinical characteristics and survival outcomes, except that BRCA2 mutation showed better PFS. The results of this study will help to understand the prognostic significance of BRCA mutation and VUS in Korean patients.
