Feasibility of articulating laparoscopic instrument use in laparoscopic adnexectomy: a multicenter prospective observational study

Abstract

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/m 2 . 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.
