Performing endoscopic retrograde cholangiopancreatography (ERCP) in patients with Roux-en-Y anatomy poses a major challenge to gastrointestinal endoscopists. In the current era of the obesity epidemic, this situation is encountered with increasing frequency due to the popularity of Roux-en-Y gastric bypass (RYGB) surgery (figure 1) and the high prevalence of gallstone disease in these patients [1-3]. (See "Bariatric procedures for the management of severe obesity: Descriptions", section on 'Roux-en-Y gastric bypass'.)
Roux-en-Y anatomy may also result from:
●Gastric resection surgery (figure 2 and figure 3). (See "Partial gastrectomy and gastrointestinal reconstruction" and "Total gastrectomy and gastrointestinal reconstruction".)
●Pancreaticoduodenectomy (figure 4 and figure 5 and figure 6). (See "Surgical resection of lesions of the head of the pancreas" and "Surgical resection of lesions of the body and tail of the pancreas".)
●Liver transplantation. (See "Living donor liver transplantation", section on 'Surgical techniques'.)
