Endoscopic Sphincterotomy Using an S-shaped Sphincterotome in Patients with a Billroth II or Roux-en-Y Gastrojejunostomy

Abstract

In spite of previous gastrojejunostomy, most patients with Billroth II anastomoses (92%) and many patients with Roux-en-Y reconstructions (33%) can be treated endoscopically for biliary diseases. The use of a conventional side-viewing endoscope in conjunction with an S-shaped sphincterotome can be recommended. This allows safe and successful endoscopic treatment of all patients in whom endoscopic access to the papilla of Vater is possible.
