Peri-vater divertieula may interfere with the normal flow of biliary and pancreatic secretion, thus leading to pancreatobiliary diseasa and the very presence of juxtapapillary diverticulum makes cannulation technically difficult and contributes to the low success rate. In this present series, the relationship between duodenal diverticula and age, sex, and biliary-pancreatic pathology was stud.ied in 1400 patients examined with ERCP. The results are as follows. 1) Duodenal diverticula was demonstrated in 73 of 1400 patients(5, 2%). 2) The incidence of duodenal divertieular increased with age and they were more frequent in men. 3) The cannulation of one or both duct system was suecessful in 69 of the 73 patients, the success rate was 94. 5%. 4) The biliary pathology was found in 41 of the 73 patients and the pancreatic pathology in 6 of the 73 patients. The rnost common finding was biliary calculi which were demonstrated in 35 patients(47. 9%).
