Summary

Compare endoscopic papillary balloon dilatation vs. endoscopic sphincterotomy for bile duct stones in: * when sphincterotomy is difficult (periampullary diverticulum, prior sphincterotomy or Billroth II anastomosis) * when there is distal CBD tapering.

Detailed description

Endoscopic papillary balloon dilatation is an alternative to endoscopic sphincterotomy for treating bile duct stones: * easier and as effective. But... * a higher risk of pancreatitis. Conditions including periampullary diverticulum, prior EST, Billroth-II anastomosis, or distal CBD tapering pose difficulty in EST and lithotripsy with increased risk of complications. Whether EPBD or EST is superior in efficacy or safety under such circumstances is not clear.
