Single port access laparoscopic surgery for large adnexal tumors: Initial 51 cases of a single institute

Investigation of initial 51 cases of single port access (SPA) laparoscopic surgery for large adnexal tumors and evaluation of safety and feasibility of the surgical technique.

We retrospectively reviewed the medical records of the first 51 patients who received SPA laparoscopic surgery for large adnexal tumors greater than 10 cm, from July 2010 to February 2015.

SPA adnexal surgeries were successfully completed in 51 patients (100%). The mean age, body mass index of the patients were 43.1 years and 22.83 kg/m², respectively. The median operative time, median blood loss were 73.5 (range, 20 to 185) minutes, 54 (range, 5 to 500) mL, and the median tumor diameter was 13.6 (range, 10 to 30) cm. The procedures included bilateral salpingo-oophorectomy (n=18, 36.0%), unilateral salpingo-oophorectomy (n=14, 27.45%), and paratubal cystectomy (n=1, 1.96%). There were no cases of malignancy and none were insertion of additional ports or conversion to laparotomy. The cases with intraoperative spillage were 3 (5.88%) and benign cystic tumors. No other intraoperative and postoperative complications were observed during hospital days and 6-weeks follow-up period after discharge.

Our results suggest that SPA laparoscopic surgery for large adnexal tumors may be a safe and feasible alternative to conventional laparoscopic surgery.
