Annular pancreas: the failure of side-to-side gastrojejunostomy anastomosis and the success of repair with Roux-en-Y gastrojejunostomy

Annular pancreas is a rare congenital anomaly characterized by a partial or complete encirclement of ectopic pancreas tissue around the duodenum. we report a case of annular pancreas in a 15 day-old infant admitted to the hospital with complaints of profuse and recurrent vomiting and loss of body weight. non-contrast abdominal x-ray showed a dilated stomach with bubbles formation around the upper abdomen. an obstruction was noted and open laparotomy was performed. upon laparotomy, pancreatic ring encircled the proximal duodenum causing an obstruction. side-to-side gastrojejunostomy was performed and passage through the bypass was satisfactory. four days after the operation, vomiting and bulging abdomen ensued. contrast abdominal x-ray demonstrated filling defects at the level of obstruction and the anastomosis made. anastomotic stricture was suspected and thus was corrected using roux-en-ygastrojejunostomy procedure. postoperative course in this patient was satisfactory and patient was discharged after 24 days of hospitalization.
