Pancreatic pseudocysts in post-gastrectomy patients treated via the duodenal minor papilla with an oblique-viewing endoscope.

Endoscopic retrograde cholangiopancreatography (ERCP) in patients after Billroth II or Roux-en-Y reconstruction is challenging because of difficulties in insertion of the endoscope into the afferent loop, which is a great distance away from the papilla of Vater, and cannulation into the desired duct from a reverse position. To facilitate ERCP, various endoscopes have been selected according to operator preference. Previously, we reported that an oblique-viewing endoscope (XK-200; Olympus, Tokyo, Japan) can contribute to successful performance of ERCP and associated procedures in Billroth II gastrectomy patients. We report here our experience with two post-gastrectomy patients with chronic pancreatitis who were treated with an oblique-viewing endoscope from the minor papilla.
