Core Tip

Core Tip: There were many studies on periampullary diverticulum (PAD) association with biliary stone and endoscopic retrograde cholangiopancreatography (ERCP) therapy. But many of them were from only single endoscopy center. In this article, the data from two centers of Lanzhou and Kyoto. We focused on comparing the choledocholithiasis characteristics with PAD, ERCP procedures and efficacy between the two centers. A total of 829 cases of choledocholithiasis with PAD in Lanzhou Center and 241 cases in Kyoto Center were involved. We find there are different characteristics of choledocholithiasis with PAD and different ERCP procedures to handle duodenal papilla between Lanzhou and Kyoto, and ERCP procedure depends on its own clinical characteristics.
