Isobaric laparoendoscopic single-site assisted extracorporeal cystectomy in treatment of selected adnexal tumors: initial experience and technique.

Laparoscopic-assisted ovarian cystectomy with exteriorization is a minimally invasive procedure. However, applicability of this procedure for transumbilical laparoendoscopic single-site (LESS) surgery is not well established. Herein, we describe our initial experience with isobaric (gasless) LESS-assisted extracorporeal cystectomy in management of selected adnexal tumors. Of 17 consecutive adnexal tumors, 15 (88.2%) (dermoid cyst, 10; serous cystadenoma, 2; mucinous cystadenoma, 1; and paraovarian cyst, 2) were successfully managed with isobaric LESS-assisted extracorporeal cystectomy. Two dermoid cysts required intracorporeal LESS cystectomy because of poor mobility of the adnexal tissue. No conversion to either conventional laparoscopic surgery or laparotomy was necessary in this series.
