[Bacteriological findings in patients with cholelithiasis and duodenal diverticuli].

In a prospective study of 70 patients with duodenal diverticula and calculous biliary tract disease, bacteriocholia with typical intestinal bacteria was found in 69%, whereas in cholelithiasis without duodenal diverticula this complication was present in 30% of the cases. With growing distance between duodenal diverticula and the papilla of Vater the rate of bacteriocholia decreases. Rising age of patients results in augmentation of bacteriocholia. Bacteriocholia on the basis of duodenal diverticula seems to present an additional pathogenetic factor for inflammatory biliary tract disease in 69% and for pancreatitis in 20% of the cases. Consequently the pathologic value of diverticulas close to the papilla of Vater is more prominent than reported so far.
