Abstract

Endoscopic cannulation of the biliary tract is a challenging technique in cases of periampullary diverticula. Many new devices and new manipulations for successful biliary cannulation have been reported. Endoscopy used to locate and cannulate a papilla hidden within a duodenal diverticulum is an effective method. However, the question of which endoscope should be chosen for this procedure, duodenoscope or gastroscope, waits to be answered.

Keywords: Endoscopic retrograde cholangiopancreatography; Intradiverticular papilla; Cannulation

Core tip: Endoscopic retrograde cholangiopancreatography is a minimally invasive surgery. However, intradiverticular papilla may cause perforation and bleeding, making it more difficult to be identified. There are many methods for successful biliary cannulation. The best method should be chosen to reduce the risk of complications. Entering the duodenal diverticulum is an excellent modality, but is it safe to perform the procedure using duodenscope?
