Jejunokolische Fisteln nach pyloruserhaltender Pankreaskopfresektion: eine ungewöhnliche Ursache für chronische Diarrhö

Jejunocolic Fistulae after Pylorus-Preserving Pancreatic Head Resection: an Uncommon Cause of Chronic Diarrhea Background: In patients with a history of pancreatic surgery, chronic diarrhea is mainly caused by exocrine pancreatic insufficiency. The authors report, for the first time, a case of jejunocolic fistulae as a cause of diarrhea and weight loss after pancreatic head resection. Case Report: A 55-year-old patient presented with chronic diarrhea and cachexia. He had undergone pylorus-preserving pancreatic head resection for chronic pancreatitis 8 years earlier. A recent colonoscopy showed an uncommon anatomy of the colon. Gastroscopy and computed tomography revealed several jejunocolic fistulae as the cause of chronic diarrhea. The patient underwent surgery and the fistula-carrying parts of jejunum and colon were resected. After surgery, his clinical status improved and he gained weight.
