45
Q

How do you treat gallstones if that is the cause of the AP?

A

ERCP (with sphincterotomy), cholecystectomy

46
Q

How do you treat necrotic tissue if that is the cause of the AP?

A

necresectomy

47
Q

How is ERCP peformed?

A
  1. to relieve biliary obstruction, with or without sphincterotomy (stent placement) to dilate the sphincter of Oddi
  2. allows ductal stones to be removed, biliary sludge to be cleared, and relief of the obstructed biliary tree driving pancreatitis
