Pancreatic heterotopia--a rare cause of bowel obstruction
Insights
Pancreatic heterotopia, an anomaly where pancreatic tissue is found outside the pancreas, can cause rare ileal obstructions. Surgical resection of the aberrant tissue provided a curative outcome for a patient with recurrent small bowel obstruction.
Area of Science:
- Gastroenterology
- Developmental Biology
- Surgical Pathology
Background:
- Pancreatic heterotopia is a congenital anomaly characterized by the presence of pancreatic tissue outside its normal anatomical location.
- Complications arising from pancreatic heterotopia are site-dependent and can mimic various pancreatic pathologies.
- In the ileum, it often presents within a Meckel's diverticulum, potentially leading to intussusception and intestinal obstruction.
Observation:
- Isolated pancreatic rests in the ileum are uncommon and frequently found incidentally during operations for unrelated conditions.
- A rare case involved a polypoid mass in the ileum containing aberrant pancreatic tissue.
- This specific presentation was causing recurrent episodes of small bowel obstruction.
Findings:
- The polypoid mass in the ileum was confirmed to be ectopic pancreatic tissue.
- Surgical intervention, specifically resection of the mass and primary anastomosis, was performed.
- The patient experienced a complete resolution of symptoms post-surgery.
Implications:
- This case highlights that isolated ileal pancreatic heterotopia, though rare, can manifest as a significant cause of small bowel obstruction.
- Surgical resection is an effective treatment, offering a curative solution for symptomatic ileal pancreatic heterotopia.
- Increased awareness among clinicians and surgeons is crucial for the timely diagnosis and management of this unusual condition.
Abstract:
Pancreatic heterotopia is a developmental anomaly. When it produces complications, symptoms depend on the site of the lesion and may reflect the whole range of pathology affecting pancreatic tissue. In the ileum, pancreatic heterotopia is usually associated with a Meckel's diverticulum and may cause intestinal obstruction by intussusception. Isolated ileal pancreatic rests are rare and usually are discovered incidentally during surgery for other conditions. A case of a polypoid mass in the ileum containing aberrant pancreatic tissue that had been causing recurrent small bowel obstruction is described. Resection and primary anastomosis were curative.
