Intraluminal duodenal diverticulum causing recurrent pancreatitis: treatment by endoscopic incision.

Intraluminal duodenal diverticulum is a recognised but rare cause of acute pancreatitis. This patient had three attacks of pancreatitis, each requiring a stay in hospital, within a four month period. The apex of the diverticulum was incised endoscopically, whereupon peas and food debris gushed from the incision site. The patient has had no further symptoms in the 12 months since the endoscopic procedure.
