Periampullary duodenal diverticula (PAD) are a common finding and the pathophysiological mechanism of occurrence may include both traction and pulsion. PAD is associated with increased incidence of diseases of the biliary system due to dysfunction of the sphincter of Oddi and ascending bacterial infection from the duodenum. The purpose of this retrospective analysis of the large population was to investigate the incidence, age and gender distribution of PAD in patients undergoing ERCP. 3259 patients examined in the period from 1989 to 2009, were involved in the retrospective analysis. We are focused on the PAD incidence and their relationship with the biliary tract diseases and the
interventional procedures carried out in the present study being the largest one in our country. 775 (379 men and 396 women) patients had PAD. The average age of 65 ± 1 years in PAD patients group were significantly older than PAD free patients (1097 men and 1387 women) at mean age of 58 ± 0,7 years. In PAD patients group 48,91% are male, 51,09%are female. Diverticula might rarely found in patients younger than 40.
