During endoscopic retrograde cholangiopancreatography (ERCP) in patients with Billroth II gastrectomy, identifying the afferent loop, access to the papilla, and cannulation in the inverted papilla are difficult [1]. With the advent of the double balloon technique, ERCP in such patients can be performed [1], but conventional accessories cannot be used because of short accessory lengths [1] [2] [3] [4] [5]. We carried out double balloon enteroscopy for ERCP (DB-ERCP) with a “short” enteroscope in a patient with Billroth II gastrectomy, and successfully performed ERCP with conventional sphincterotomy and metallic stent placement.

A 79-year-old man, who had undergone Billroth II gastrectomy for gastric cancer, presented with jaundice. Computed tomography (CT) showed a tumor in the common bile duct causing biliary tree dilatation. We performed DB-ERCP with a “short” enterosope, EC450-BI5 (Fujinon-Toshiba, Osaka, Japan), which has a 2.8-mm working channel and a 152-cm working length and for which conventional accessories are available. The enteroscope successfully reached the duodenal stump. Despite the inverted papilla being located at the 11 o’clock position in the visual field, the papilla could be moved to the 6 o’clock position by keeping the overtube balloon inflated and rotating the enteroscope, resulting in successful cannulation ([Fig. 1]). The diagnosis of malignant biliary structure caused by recurrent gastric cancer was made based on imaging and histologic studies ([Fig. 2]). After endoscopic sphincterotomy with a conventional sphincterotome, a metallic stent was easily inserted across the stricture with uneventful recovery ([Fig. 3]).

ERCP is technically challenging and often unsuccessful in patients with altered gastrointestinal anatomy [1] [3] [4] [5]. Several authors have performed DB-ERCP in such patients, with the use of a standard EN-450P5/20 enteroscope or a therapeutic EN-450T5 enteroscope [1] [2] [3] [4] [5]. Because both enteroscopes have a working length of 200 cm, specialized custom-made or very limited accessories are available [1] [2] [3] [4] [5]. We therefore recommend the “short” enteroscope for diagnostic and therapeutic ERCP in patients with altered gastrointestinal anatomy because all conventional accessories are available.
