Summary
Heterotopic pancreas, a rare condition, presents diagnostic challenges despite advanced imaging. Surgical removal of these gastroduodenal tumors effectively alleviates patient symptoms.
Area of Science:
- Gastroenterology
- Surgical Pathology
Background:
- Heterotopic pancreas is an uncommon condition where pancreatic tissue is found outside its normal location.
- Diagnosis remains challenging due to non-specific symptoms and limitations of current imaging modalities.
Purpose of the Study:
- To evaluate the clinical presentation, diagnostic methods, and surgical outcomes of heterotopic pancreas.
- To highlight the diagnostic difficulties associated with this rare entity.
Main Methods:
- Retrospective analysis of 17 patients surgically treated for heterotopic pancreas.
- Review of clinical symptoms, endoscopic findings, imaging results, and pathological reports.
Main Results:
- Epigastric pain (77%), abdominal fullness (30%), and tarry stools (24%) were the most common symptoms.
- Gastroduodenal tumors were often diagnosed via gastroduodenoscopy (67%) or upper GI series (71%), with only one case suspected preoperatively.
- Various imaging techniques, including CT and ultrasound, showed limited success in preoperative diagnosis.
- Lesions were predominantly located in the stomach, ranging from 1 to 3 cm in size.
- Surgical excision resulted in symptom relief for all patients.
Conclusions:
- Heterotopic pancreas continues to be a diagnostic challenge, even with advancements in medical imaging.
- Surgical intervention is effective in managing symptomatic heterotopic pancreas.
