Insights
A rare case of heterotopic pancreas (HP) in a child caused ileal intussusception, mimicking other conditions. This first-in-Peru report highlights HP as a potential cause of intestinal obstruction in pediatric patients.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Pathology
Background:
- Heterotopic pancreas (HP) is a rare congenital anomaly.
- Intussusception is a common cause of intestinal obstruction in children.
- HP-induced intussusception in pediatric patients is exceptionally rare.
Observation:
- A one-year-old male presented with anorexia, irritability, abdominal pain, and bloody stools.
- Initial diagnosis was complicated by allergic colitis, delaying surgical intervention.
- Abdominal CT revealed a characteristic "target" sign, suggestive of intussusception.
Findings:
- Exploratory laparotomy confirmed ileoileal intussusception.
- A mass identified during surgery was histopathologically diagnosed as heterotopic pancreas.
- This represents the first reported case of pediatric intussusception caused by HP in Peru.
Implications:
- Highlights the importance of considering rare etiologies like HP in pediatric intussusception.
- Emphasizes the need for prompt diagnosis and surgical management of intussusception.
- Contributes to the limited literature on HP as a cause of pediatric intestinal obstruction.
Abstract:
The heterotopic pancreas (HP) is a rare condition in the pediatric population. HP cases involving an ileal intussusception are rare in children and very rarely reported, usually presenting with symptoms of intestinal obstruction. We report the case of a one year old male patient with a chronic history of anorexia, irritability, abdominal pain, accompanied by intermittent episodes of "currant jelly" stools that evolved to rectal bleeding. The patient presented a concomitant diagnosis of allergic colitis, which prolonged the effective surgical treatment at an external health center. In the abdominal CT scan, the classic "target" sign was found. In the exploratory laparotomy an ileoileal intussusception was confirmed, a mass was found that the histopathology laboratory confirmed as HP. To our knowledge, it is the first case of pediatric intussusception by HP reported in Peru.
