To the Editor.—Periampullary duodenal diverticula are said to cause biliopancreatic stasis and bacterial overgrowth, which may result in pancreatitis, cholangitis, and gallstone formation.1 Different operative interventions have been described, including sphincteroplasty, choledochoduodenostomy, Billroth II gastrectomy, and, recently, duodenojejunostomy.2 An example of the latter procedure is described in the following case report.
