Abstract

Afferent loop syndrome (ALS) is a rare cause of recurrent pancreatitis. Recurrent pancreatitis in association with ALS can develop due to impaired outflow of pancreatic juice or reflux of enteric secretions caused by increased intraluminal duodenal pressure. Here, we report a case of ALS presenting as recurrent acute pancreatitis due to chronic intermittent partial obstruction of the third portion of the duodenum caused by postoperative adhesion. Interestingly, pancreatic histology showed a granulocytic epithelial lesion, which is a diagnostic feature of type 2 autoimmune pancreatitis (AIP, idiopathic duct centric chronic pancreatitis [IDCP]). From this case we learned that the diagnosis of type 2 AIP should be made in the appropriate clinical setting.
