title: [Transumbilical cholecystectomy].
abstract: BACKGROUND
  Recent development of minimally invasive surgery has raised interest in laparoscopic surgery through a single abdominal incision. The most common names for this technique is single incisional laparoscopic surgery (SILS) or laparoscopic endoscopic single-site surgery (LESS). This article describes the first experiences at our department with cholecystectomy using this new technique.
  
  
  METHODS
  Twelve patients underwent cholecystectomy with SILS technique at Bispebjerg Hospital. The exclusion criteria were previous abdominal surgery and known previous cholecystitis.
  
  
  RESULTS
  The median operation time was 89 minutes. Four patients presented signs of cholecystitis or adhesions. There was no perioperatives complications. Ten patients were discharged at the day of the operation and two the day after.
  
  
  CONCLUSIONS
  This patient series reveals that SILS technique is feasible in selected patients. It yields an optimal cosmetic result, but conclusions about the potential benefits regarding postoperative pain, nausea, port-site bleeding, infection, port-site hernia and bile duct lesions as compared with conventional laparoscopic cholecystectomy remain unclear. Randomized trials are warranted to answer these questions.
