Laparoendoscopic single-site surgery (LESS) for large benign adnexal tumors: one surgeon's experience over one-year period.



To present the authors' experience with laparoendoscopic single-site surgery (LESS) surgery for large benign adnexal tumors and to compare the removal time of resected specimen with that of conventional laparoscopy.


Ten consecutive patients underwent LESS for huge adnexal tumors at Myongjil Hospital, Korea between March 2011 and July 2012. A modified open Hasson technique was used to gain access to the abdominal cavity. The single-port device was inserted trans-umbilically into the wound opening. After suction of large amount of fluid content, LESS salpingo-oophorectomy was performed. The resected adnexal specimen was placed into a LapBag for removal out of the abdominal cavity. The authors compared the removal time of resected specimen between LESS and previously performed conventional laparoscopy for large benign adnexal tumors.


The adnexal tumors in this study were all very large cystic tumors reaching near or over the umbilicus. It took less than ten minutes for the removal of the resected adnexal tumors in all LESS cases (three to ten minutes), much less time than that of the conventional laparoscopy (usually ten to 17 minutes).


LESS for large benign adnexal tumors is feasible and removal of resected adnexal tumor is easier than conventional laparoscopic surgery.
