HEMORRHAGE INTO A DUODENAL CYST WITH ECTOPIC GASTRIC EPITHELIUM, A RARE CAUSE OF GASTRIC OUTLET OBSTRUCTION IN AN ADULT

Background: Duodenal duplications, including also cysts,vith gastric e pithelium, are congenital anomalies observed in less than 1 per 100,00 0 births. They are usually detected in infants or children. Aim: To ev aluate and discuss the diagnostic work-up and treatment. Material and Methods: A rare case of haemorrhage in the duodenal cyst in a 32-year- old woman with gastric outlet obstruction is presented. Results: Compu ted tomography (CT) revealed cystic lesion in the duodenum. Endoscopic retrograde cholangiopancreatography (ERCP) showed normal biliary and pancreatic ducts. Final histology demonstrated cystic lesion in the du odenum which was lined with gastric mucosa. Conclusion: Preoperative C T and ERCP are important in the differential diagnosis and planning of treatment in duodenal cystic lesions.
