INTESTINAL OBSTRUCTION AS A RESULT OF PANCREATIC ECTOPY IN JEJUNUM: A CASE REPORT AND LITERATURE REVIEW.

Pancreatic heterotopia is a relatively rare condition that implies pancreatic tissue anatomically separated from the main gland, showing no vascular or ductal continuity. It is known to occur in many sites of gastrointestinal tract, with stomach being the most common one. This case is of great interest because ectopic pancreatic tissue in jejunal wall presented as bowel obstruction. The aim of this article is to provide a review of clinical, histopathologic and immunohistochemical features of ectopic pancreatic tissue in jejunum, emphasizing the possible diagnostic pitfalls in gastrointestinal tract, especially in its upper parts. Knowing the most common locations, imaging features and histopathologic criteria, the diagnosis of pancreatic heterotopia could be successfully set preoperatively. Associated complications are various and sometimes difficult to handle, so accurate and precise diagnosis, as well as surgical resection, is often needed.
