A 30-year-old woman visited our hospital with a chief complaint of epigastric pain. An X-ray examination of the stomach showed an egg-sized defect in the second portion of the duodenum. An endoscopic examination also demonstrated a smooth mass with bridging folds above the anterior wall of the papilla of Varter. A touch of the site by a biopsy forceps suggested cystic properties of the mass. This finding was supported also by an ultrasonic examination result. No communication was found on the ERCP between the mass and either the pancreatic duct or the bile duct, nor were any abnormal findings noted on either duct. From the results of various examinations, a duodenal duplication was suspected and a surgical operation was performed. The enucleated cyst was found to contain white turbid fluid. Histopathological examination of cystic wall revealed that the internal surface of the cyst was covered by the duodenal mucosa and the cyst held the muscular tunics common with the duodenal internal cavity. From this, duodenal duplication was diagnosed. 17 cases of this disease has been reported so far in Japan and we reviewed the 18 cases including this case.
