Intussusception Caused by Heterotopic Pancreas: A Tunisian Case Series of 5 Pediatric Patients

Heterotopic pancreas (HP) is a rare congenital developmental anomaly of the gastro-intestinal tract, defined as the presence of pancreatic tissue found in ectopic sites. Intussusception caused by isolated HP is extremely rare. Pediatric reports concerning this pathology are case reports. Here, we report cases of secondary intussusception, in which conservative treatment failed and surgery was performed. The aim of this review is to study the epidemiologic and clinical aspects of HP in pediatric patients from our institution. We retrospectively collected patients who were treated in the pediatric surgery department for intussusception caused by HP, from January 1986 to November 2018. We investigated five patients, three boys and two girls, aged 5 months to 2 years. The diagnosis was made incidentally during the operation. HP was found in the jejunum in three cases and in the ileum in two cases. HP was removed. The postoperative course was uneventful. Although rare, HP should be included in the differential diagnosis of gastrointestinal diseases, causing secondary bowel intussusception.
