Summary
A rare case of aberrant pancreatic tissue in the mesentery was found during emergency surgery for small bowel obstruction. This finding highlights the importance of thorough surgical examination in urgent abdominal cases.
Area of Science:
- Gastroenterology
- Surgical Pathology
- Abdominal Surgery
Background:
- Pancreatic heterotopia, or aberrant pancreatic tissue, is a rare congenital anomaly.
- Advances in medical imaging have made incidental discoveries less common.
- This case presents a mesenteric localization of aberrant pancreas discovered during an emergency abdominal procedure.
Observation:
- A 26-year-old male presented with acute small bowel obstruction.
- Surgical exploration revealed an ileo-parietal adherence and an inflammatory focus of appendicular origin.
- A bilobate mass with pancreatic characteristics was identified in the mesentery of the jejunum.
Findings:
- Histopathological examination confirmed the mass as pancreatic tissue with both exocrine and endocrine components.
- The aberrant tissue was classified as Type I according to Heinrich's classification.
- Adjacent jejunal segments appeared macroscopically healthy.
Implications:
- This rare topographic entity underscores the significance of meticulous surgical exploration in the abdominal cavity.
- Urgent surgical scenarios, especially with limited preoperative imaging, necessitate careful intraoperative assessment.
- Thorough examination can lead to the discovery of rare anomalies like mesenteric pancreatic heterotopia.
