title: The relationship between juxtapapillary diverticula and biliary calculi. An endoscopic study.
abstract: A systematic prospective endoscopic study of the incidence of juxtapapillary diverticula in a variety of digestive disorders was undertaken in the Surgical Clinic at the Provincial Hospital, Port Elizabeth. The findings were related to conditions commonly encountered. The following frequency distribution was found: 33 diverticula out of 164 patients associated with gallstones (20.1%); 15 out of 668 patients not associated with gallstones (2.2%); 1 out of 39 patients with pancreatitis (2.6%); and 3 out of 146 patients with gastric ulcer (2.1%). No diverticulum was noted in 111 patients with duodenal ulcer. These findings suggest that juxtapapillary diverticula are nearly 10 times more common in patients with gallstones than in patients without. There is evidence to suggest that these diverticula tend to precede the gallstones. It is conceivable that juxtapapillary diverticula may predispose to gallstones. Alternatively, both conditions may be manifestations of another underlying disorder as yet to be defined.
