[Duodenal diverticula and organic diseases of the pancreatoduodenal area].

X-ray examination of 123 patients showed duodenal diverticula seated primarily in the descending part. In 60% of the patients, they were located in the area of the major duodenal papilla. Duodenal diverticula were coupled significantly more often with chronic pancreatitis than with chronic cholecystitis and ulcer disease of the duodenum. Combined choleduodenography is a method of choice for establishing interrelations between a diverticulum and the major duodenal papilla. In addition to parapapillary diverticula, the development of pancreatitis may be promoted by the diverticulum taking root in the pancreatic parenchyma.
