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

Objective: 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.

Methods: 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.

Results: 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.

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