Jejunal Ectopic Pancreas Causing Gastric Outlet Obstruction

Ectopic pancreas (EP) is a rare congenital anomaly where pancreatic tissue is found outside the pancreas without any ductal or vascular connection. It is commonly located in the stomach but can also occur in the jejunum, ileum, liver, spleen, and other sites. EP is usually asymptomatic but can cause complications like inflammation, obstruction, or malignant transformation. This case report presents a patient with Ectopic Pancreas in the proximal jejunum, leading to gastric outlet obstruction. The patient had chronic abdominal pain and weight loss. Initial investigations, including endoscopic biopsies, were inconclusive, but contrast-enhanced CT suggested EP. Surgical intervention was performed due to persistent symptoms, revealing a contained jejunal perforation. Histopathology confirmed the Ectopic Pancreas and the patient recovered well postoperatively. This case highlights the diagnostic challenges of the Ectopic Pancreas. While imaging aids in diagnosis, histopathology remains the gold standard. Awareness of the ectopic Pancreas as a rare cause of gastric outlet obstruction is crucial for timely management.
