Successful surgical treatment for hepatic encephalopathy caused by a pancreatic siphon: report of a case.

We report herein the case of a 39-year-old man with cirrhosis of the liver who developed hepatic encephalopathy and progressive diabetes caused by a pancreatic siphon after undergoing a distal splenorenal shunt (DSRS) for a variceal hemorrhage. Radiologic occlusion was judged to be inappropriate because of the extensive DSRS. The DSRS was surgically closed 6 years after the operation to restore portal perfusion. To alleviate the portal hypertension, splenectomy and gastric devascularization were performed, which proved successful, as the encephalopathy disappeared completely, the ammonia levels decreased, liver function improved, and the diabetes subsided. Our experience indicates that a small percentage of cirrhotic patients who undergo DSRS with longterm followup may develop various undesirable complications, although some of these patients benefit from a combination of surgical shunt occlusion, splenectomy, and gastric devascularization.
