This film shows an incidental finding on small bowel series - 2 diverticula project from the third part of the duodenum.
Duodenal diverticula typically arise in the periampullary medial 2nd part of the duodenum (70%). Twenty-six percent arise in the 3rd or 4th parts, as in this case. Ninety percent of duodenal diverticula are asymptomatic. Complications include infection, haemorrhage, stasis, perforation, and pancreaticobiliary disease (if the diverticulum is periampullary). The papilla of Vater may be within a diverticulum, creating a problem for the endoscopist intent on finding and otomising it.
