| [ Summary ] | "Duplication of the alimentary tract" is a concept suggested by Ladd and Gross. The duodenum is an uncommon site for the occurrence of duplication, accounting for 4.7% of such anomalies in Japanese literature, by Okuda. Duplication of the duodenum is more commonly found as a spherical cystic lesion on the medial wall of the first or second parts of the duodenum, sometimes in the pancreatic head, but in rarer cases as a tubular structure, extending up into the thorax, similar to a very long diverticula. Duplication cysts arising from the second parts of the duodenum, are frequently incorporated into the bile duct and the pancreatic duct. In such cases, symptoms of severe pancreatitis are observed. In some cases, the cystic walls are lined with gastric mucosa, causing ulceration and bleeding. Duodenal cysts may be detected with a barium series. A US. endoscopic examination frequently reveals an elevated submucosal cystic tumor. Angiography, CT scans and MR imaging can give more exact information in relation not only the cystic wall, but also to the adjacent organs. In the majority of cases, the treatment of choice is resection of the duplication and the adjacent duodenal wall made necessary because of carcinogenesis. |
