title: Randomized clinical trial of single-incision laparoscopic cholecystectomy versus minilaparoscopic cholecystectomy.
abstract: BACKGROUND
  Transumbilical single-incision laparoscopic cholecystectomy (SILC) and minilaparoscopic cholecystectomy (MLC) are both increasingly being used to treat symptomatic gallstones. The present study compared SILC and MLC with respect to outcome in a prospective randomized trial.
  
  
  METHODS
  Seventy patients with symptomatic cholelithiasis were randomized to SILC or MLC (35 in each group). The primary outcome measure was postoperative pain. Secondary outcomes were duration of operation, complications, postoperative analgesic requirements, length of hospital stay, cosmetic result, wound length and time to return to work.
  
  
  RESULTS
  Surgical complications, postoperative pain scores, analgesic requirements and time to return to work were similar for both procedures. Statistically significant advantages of SILC were a shorter hospital stay, shorter total wound length and better cosmetic appearance. Duration of operation was significantly shorter for MLC.
  
  
  CONCLUSIONS
  SILC is superior to MLC in terms of cosmetic outcome, but not in postoperative pain and requirement for analgesics.
