A case of ectopic pancreas confirmed by double-balloon enteroscopy to determine bleeding source

Abstract

An 80-year-old woman was admitted to our hospital because of anterior chest pain. There were past histories of diabetes mellitus, hypertension, and unstable angina pectoris. When she was first seen, she showed serious anemia due to melena. Despite gastrofiberscopy, colonscopy, and enteroclysis, the bleeding source was unclear. We suspected a small intestinal lesion, and performed double-balloon enteroscopy. A submucosal tumor with an erosive top was found, and this tumor was considered to be the bleeding source. After percutaneous transluminal coronary angioplasty (PTCA) to treat unstable angina due to intestinal hemorrhage, partial excision of the ileum was performed. The pathological diagnosis was ectopic pancreas of HeinlichII.
We present a case of adult ileal ectopic pancreas confirmed by double-balloon enteroscopy.
