[Hepatic encephalopathy following a Whipple operation].

A 65-year-old woman was admitted to our hospital with progressive confusion and hypersomnia. During admission she became comatose which was found to be caused by hepatic encephalopathy. Fifteen years earlier she had undergone a Whipple's pancreaticoduodenectomy for an adenocarcinoma of the pancreatic head. She had developed secondary endo- and exocrine pancreas insufficiency and a fatty liver. Non-alcoholic fatty liver disease (NAFLD) is a little-known late complication of a pancreaticoduodenectomy, possibly caused by postoperative exocrine pancreas insufficiency. NAFLD may lead to non-alcoholic steatohepatitis (NASH) which can ultimately result in liver cirrhosis. There have been no previous reports in the literature of hepatic encephalopathy presenting as liver failure secondary to NASH following pancreaticoduodenectomy.
