Periampullary diverticulum: an unusual cause of double duct obstruction.

摘要

Double duct dilation in patients with deranged liver biochemistry inevitably leads to a careful search for a malignant cause because small ampullary and pancreatic carcinomas are not always detectable by radiology alone. In this setting a multimodality approach is often used combining multidetector CT, magnetic resonance imaging (MRI), EUS, and ERCP. We discuss a case where periampullary duodenal diverticulum was determined the cause for double duct obstruction after surgical resection, not confirmed by prior investigation.
