Duodenal "diverticulization" for massive haemorrhage from pancreatic pseudocyst

A case of massive haemorrhage into the gastrointestinal tract from a pancreatic pseudocyst is presented. The pseudocyst was a complication of acute pancreatitis, and control of the haemorrhage by operation was difficult because of the friability of the cyst wall. The surgical procedure called duodenal diverticulization is described and was found to be a useful adjunct to suture ligation for bleeding which was almost uncontrollable and when death of the patient seemed inevitable.
