title: ERCP and sphincterotomy in the context of laparoscopic cholecystectomy: academic and community practice patterns and results.
abstract: OBJECTIVE
  To study the effect of practice setting and practitioner experience on the use and results of ERCP and sphincterotomy in the context of laparoscopic cholecystectomy.
  
  
  METHODS
  Data were collected on 780 ERCPs performed before or after laparoscopic cholecystectomy. Biliary endoscopists at four academic centers and 33 community-based gastroenterologists of varying experience participated.
  
  
  RESULTS
  Indications for perioperative ERCP were similar in academic centers and community practice, but academic experts performed a significantly higher proportion of postoperative procedures. Success rates were high for all participants, although the least experienced group of community-based gastroenterologists had a significantly lower rate of success with sphincterotomy. Complication rates did not vary significantly among participants.
  
  
  CONCLUSIONS
  Experienced community-based gastroenterologists can perform ERCP and sphincterotomy in the context of laparoscopic cholecystectomy with results comparable to those of academic experts. Gastroenterologists with a life-time experience of fewer than 200 ERCPs have lower success rates for sphincterotomy than more experienced practitioners in either practice setting. ERCP performed in community or academic settings can provide safe and effective management of common bile duct stones and biliary leaks or strictures that occur after laparoscopic cholecystectomy.
