title: Timing of urgent laparoscopic cholecystectomy does not influence conversion rate.
abstract: BACKGROUND
  The optimal treatment of acute gallstone disease is urgent laparoscopic cholecystectomy, but there is confusion about the effect of delay in operation on conversion rates. Most reports suggest that delay beyond 3 or 4 days leads to a higher conversion rate. This study assessed the conversion rate in relation to the timing of laparoscopic surgery.
  
  
  METHODS
  This institution operates a specialist-led protocol for the urgent management of all admissions with acute gallstone disease. Data were collected prospectively over 6 months.
  
  
  RESULTS
  Between March and August 2002, 84 patients with acute gallstone disease underwent urgent laparoscopic cholecystectomy at the index admission with an overall conversion rate of 12 per cent. Four of 40 procedures carried out within 3 days of admission were converted, compared with six of 44 after 3 days. Five of 46 carried out within 4 days of admission were converted, compared with five of 38 after 4 days. There were no deaths and one common bile duct injury.
  
  
  CONCLUSIONS
  As long as the procedure is carried out by experienced upper gastrointestinal surgeons working within a specialist-led protocol, the conversion rate for laparoscopic cholecystectomy can be as low as 12 per cent. The timing of urgent laparoscopic cholecystectomy has no impact on the conversion rate.
