Symptomatic pyloric pancreatic heterotopia: report of three cases and review of the literature.

Abstract

Most pancreatic heterotopias are asymptomatic and require no treatment. This entity is extremely difficult to diagnose preoperatively as the cause of upper gastrointestinal tract symptoms and therefore requires a high index of suspicion. Symptomatic lesions should be excised, and this can be safely carried out by minimally invasive techniques depending on the size and the anatomical location.
