The heterotopic pancreas in children. Apropos of 4 new cases

: The authors report 4 new cases of heterotopic pancreas in children with prepyloric, jejunal, Meckel's diverticulum and mesenteric localization. Clinical manifestations were: hemorrhage in the prepyloric localization, abdominal pain in the mesenteric and Meckel's diverticulum and ileus in the jejunum localization. The authors emphasise the difficulties of preoperative diagnosis of the pancreatic heterotopias, owing to their usually small size and the necessity of surgical treatment.
