a) Cholecystectomy should be done before discharge in severe pancreatitis to prevent recurrent attacks

b) Cholecystectomy should be done in same admission as pancreatitis when severe disease is excluded

c) Early cholecystectomy has been shown to have more complications than interval choelcystectomy

d) Early cholecystectomy increases technical complications

 Ans b

"Poncho trial " answers this question

Early  cholecystectomy (just before discharge, when the patient has recovered and severe disease excluded), compared to interval cholecystectomy, effectively reduces

  1. The rate of recurrent gallstone-related complications in patients with mild biliary pancreatitis,
  2. low added risk of complications.

Evidence on the timing of cholecystectomy in severe pancreatitis is scarce. Cholecystectomy is recommended after all signs of pancreatic necrosis have been resolved or if they persist more than 6 weeks
