INTESTINAL OBSTRUCTION AS A RESULT OF PANCREATIC ECTOPY IN JEJUNUM: A CASE REPORT AND LITERATURE REVIEW

Area of Science:

• Gastroenterology
• Surgical Pathology
• Abdominal Imaging

Background:

• Pancreatic heterotopia involves anatomically separate pancreatic tissue without vascular or ductal connection to the main gland.
• Commonly found in the gastrointestinal tract, most frequently in the stomach.
• Ectopic pancreatic tissue in the jejunum can manifest as a critical complication, such as bowel obstruction.

Purpose of the Study:

• To review the clinical, histopathologic, and immunohistochemical features of ectopic pancreatic tissue in the jejunum.
• To highlight potential diagnostic challenges in the gastrointestinal tract, particularly the upper regions.
• To emphasize the importance of preoperative diagnosis for optimal patient outcomes.

Main Methods:

• Literature review of clinical presentations, imaging findings, and histopathologic criteria for pancreatic heterotopia.
• Analysis of immunohistochemical markers for accurate tissue identification.
• Case study focusing on jejunal ectopic pancreatic tissue presenting as bowel obstruction.

Main Results:

• Ectopic pancreatic tissue in the jejunum can present as a rare cause of bowel obstruction.
• Accurate diagnosis relies on recognizing characteristic imaging features and histopathologic findings.
• Potential diagnostic pitfalls exist, especially in upper gastrointestinal tract imaging and interpretation.

Conclusions:

• Preoperative diagnosis of pancreatic heterotopia is achievable with knowledge of common locations, imaging characteristics, and histopathologic criteria.
• Timely and precise diagnosis is essential for managing associated complications, often requiring surgical resection.
• Understanding the varied presentations and diagnostic nuances of ectopic pancreatic tissue improves patient care.
