[Duodenal diverticula].

Abstract

Duodenal diverticula occur in 0.016 to 5.19% of patients undergoing roentgenographic investigation of the upper gastrointestinal tract. They are classified into extraluminal and intraluminal types and are usually found near the papilla of Vater. The majority of these cases are asymptomatic. These diverticula occasionally result in the obstruction of the biliary and/or pancreatic ducts, haemorrhage or perforation. Symptomatic cases may require endoscopic or surgical intervention. The management should be individualized to the kind of complication, type, and location of the diverticulum. Surgical procedures in this area may be technically difficult and associated with high mortality and morbidity. Elective treatment of uncomplicated duodenal diverticula is usually not justified. The difficulties in identifying these lesions as the source of symptoms are emphasized.
