Brief 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.

Condition or disease Intervention/treatment
Choledocholithiasis Procedure: Endoscopic papillary balloon dilatation Procedure: Endoscopic sphincterotomy

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.
