Core Tip

Core tip: Endoscopic retrograde cholangiopancreatography (ERCP) in Billroth II gastrectomy anatomy has been considered a difficult procedure due to the surgical alteration. To date, there has been a paucity of comparative studies regarding ERCP in Billroth II gastrectomy patients. In current study, we systematically and comprehensively reviewed the literatures regarding ERCP in Billroth II gastrectomy cases. The performance of ERCP in the Billroth II gastrectomy has been improving with choice of various type of endoscope and sphincter therapy. More comparative studies are required to perform effective and safe ERCP in Billroth II gastrectomy population.
