title: Is single-port laparoscopy for benign adnexal disease less painful than conventional laparoscopy? A single-center randomized controlled trial.
abstract: OBJECTIVE
  To determine whether laparo-endoscopic single-site surgery (LESS) results in less postoperative pain and a better cosmetic surgical scar compared with conventional laparoscopy.
  
  
  METHODS
  Prospective randomized controlled trial.
  
  
  METHODS
  A county hospital in Norway.
  
  
  METHODS
  Forty women with benign adnexal disease or a hereditary cancer risk scheduled for laparoscopic adnexal surgery.
  
  
  METHODS
  LESS or conventional laparoscopy.
  
  
  METHODS
  Postoperative pain 24 hours after surgery.
  
  
  RESULTS
  There was no difference in pain at 24 hours after surgery, with a mean score of 3.0 (SD 2.1) in the LESS group and 2.5 (SD 1.5) in the conventional laparoscopy group. Significantly more shoulder tip pain was reported by women undergoing LESS compared with those having conventional surgery at 6 and 24 hours after surgery. A high satisfaction with the cosmetic result was reported in both groups, with no significant difference in the Manchester scar scale score.
  
  
  CONCLUSIONS
  Although similar levels of postoperative pain are experienced by women having LESS and conventional laparoscopic surgery, women having LESS report significantly more shoulder tip pain compared to those having conventional laparoscopic surgery. This may relate to a significantly longer operation time in the LESS group.
