Abstract: Objective To investigate the relationship between the incidence of duodenal papilla diverticulum and biliary and pancreatic diseases, and the influence on ERCP. Methods A total of 1203 patients, including 475 females and 728 males, underwent abdominal CT from July 1, 2020 to October 1, 2020 in Guangzhou Zengcheng District People′s Hospital. Among them, 23 patients with choledocholithiasis, cholangitis or biliary pancreatitis underwent ERCP. We observed the incidence of duodenal papillary diverticulum, the incidence of duodenal papillary diverticulum in patients with cholangiopancreatic diseases, the incidence of cholangiopancreatic diseases in patients with duodenal papillary diverticulum, and the success rate of ERCP in patients with duodenal papillary diverticulum. And we analyzed the relationship between duodenal diverticulum and cholangiopancreatic diseases and its influence on ERCP. Results The incidence of duodenal diverticulum was higher in women, P<0.05. The incidence of duodenal diverticulum was higher in patients over 40 years old, P<0.05. The incidence of extrahepatic bile duct stones, bile duct dilatation and pancreatitis were higher in patients with duodenal diverticulum than in patients without duodenal diverticulum, P<0.05. And the detection rate of duodenal diverticulum was higher in patients with extrahepatic bile duct stones, cholangitis and pancreatitis, P<0.05. ERCP intubation in duodenal diverticulum was difficult and the success rate was relatively low （P<0.05）. Conclusion Duodenal diverticulum has certain relationship with extrahepatic bile duct stones, cholangitis, pancreatitis and other diseases; ERCP intubation in duodenal diverticulum is difficult and the success rate is relatively low. Paying attention to and understanding of juxtapapillary duodenal diverticulum, preoperative imaging evaluation and mastering ERCP related skills are often helpful to improve the success rate of intubation with juxtapapillary duodenal diverticulum.
