title: A comparison of clinical and surgical outcomes between laparo-endoscopic single-site surgery and traditional multiport laparoscopic surgery for adnexal tumors.
abstract: OBJECTIVE
  The purpose of this study was to compare clinical and surgical outcomes between laparo-endoscopic single-site (LESS) surgery and traditional multiport laparoscopic (TML) surgery for treatment of adnexal tumors.
  
  
  METHODS
  Medical records were reviewed for patients undergoing surgery for benign adnexal tumors between January 2008 and April 2012 at our institution. All procedures were performed by the same surgeon. Clinical and surgical outcomes for patients undergoing LESS surgery using Glove port were compared with those patients undergoing TML surgery.
  
  
  RESULTS
  A review of 129 patient cases undergoing LESS surgery using Glove port and 100 patient cases undergoing TML surgery revealed no significant differences in the baseline characteristics of the two groups. The median operative time was shorter in the LESS group using Glove port at 44 minutes (range, 19-126 minutes) than the TML group at 49 minutes (range, 20-196 minutes) (P=0.0007). There were no significant differences between in the duration of postoperative hospital stay, change in hemoglobin levels, pain score or the rate of complications between the LESS and TML groups.
  
  
  CONCLUSIONS
  LESS surgery showed comparable clinical and surgical outcomes to TML surgery, and required less operative time. Future prospective trials are warranted to further define the benefits of LESS surgery for adnexal tumor treatment.
