Pancreaticojejunal anastomosis is preferable to pancreaticogastrostomy after pancreaticoduodenectomy for longterm outcomes of pancreatic exocrine function.

Background: The aim of this study was to evaluate pancreatic exocrine and endocrine function after pancreaticoduodenectomy.

Study Design: Pancreatic exocrine function was evaluated by a questionnaire and medical examination of stools after discontinuing pancreatic enzyme supplements for at least 10 days. Severe steatorrhea was defined as frequent, nauseating, yellow, and pasty stools, fecal output >200 g/d for more than 3 days.
