Abstract

The heterotopic pancreas is defined as the presence of pancreatic tissue lacking anatomical and vascular continuity from the main body of pancreas. Its incidence has been reported as widely ranging from 0.55~13.7% in autopsy studies and 0.2% in upper abdominal laparotomies. The most common sites are the antrum of stomach, duodenum and proximal jejunum. But, lesions have also been found in the ileum, Meckel diverticulum, common bile duct and the esophagus. Most cases are incidentally encountered during surgery, and on rare occasions, epigastric pain, hemorrhage, gastric outlet obstruction and intussusception have been directly attributable to the presence of the heterotopic pancreas. A 3-month-old boy presented with 1-day history of vomiting and irritability. Intussusception was confirmed on ultrasound scan. At laparotomy there was an irreducible ileoileal intussusception, the intussuscepted portion of ileum was resected and end to end anastomosis was performed. Histologically, the mass was found to be composed of pancreatic tissue.
