BACKGROUND AND STUDY AIMS: Some patients admitted for endoscopy present a gastrojejunostomy with a Billroth II anastomosis or Roux-en-Y reconstruction. The gastrointestinal reconstruction hampers endoscopic diagnosis and treatment of the biliary and pancreatic tract. The present paper describes a new procedure facilitating endoscopic retrograde cholangiopancreatography (ERCP) in patients who have undergone gastrojejunostomy. PATIENTS AND METHODS: ERCP was attempted in 65 patients with gastrojejunostomy. A conventional side-viewing endoscope was advanced into the duodenal stump, and a modified catheter was pushed through the endoscope. The cutting wire of the modified catheter winds round the catheter at a pivotal point between the catheter's proximal and distal holes. This allows the catheter tip to be forced into an S-shape when the wire is pulled. Since the cutting wire can easily be adjusted to the papillary roof, safe and successful endoscopic sphincterotomy can be carried out. RESULTS: We were able to advance the conventional side-viewing endoscope into the duodenal stump in 92% of the patients (n = 59) with Billroth II gastrojejunostomies, and in 33% of the patients (n = 6) with Roux-en-Y anastomoses. Whenever it was possible to reach the duodenal stump, cannulation and sphincterotomy of the papilla of Vater was successful. Ninety-six percent of the patients who underwent sphincterotomy (n = 54) immediately benefited from biliary decompression. One major complication occurred, with a patient suffering a retroperitoneal perforation during endoscopic sphincterotomy; the patient later died, despite three subsequent surgical operations. CONCLUSIONS: 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.
