A strange case of double annular pancreas.

CONTEXT: The pancreas is a soft lobulated gland situated transversely across the upper part of the posterior abdominal wall. Its parts include the head, neck, body and tail. Annular pancreas is a rare condition where the head of the pancreas surrounds the second part of the duodenum like a ring. CASE REPORT: We observed a rare type of double annular pancreas where the uncinate process encircled the third part of the duodenum. A process from the head of the pancreas encircled the junction between the first and second parts of the duodenum incompletely. There was a large artery running along the anterior border of the pancreas. The artery took origin from the superior mesenteric artery.
CONCLUSION: This case may be of interest to gastroenterologists and surgeons.
