Abstract
A case, two month-old male, is reported who complained of the massive hemorrage from duodenal ulcer on day 6 after the operation for the biliary atresia (BA). The patient underwent the hemostatic simple suture of the ulcer portion, and the postoperative course was not eventful. It is conceivable that the disorder of mucosal protective factor and the augmentation of aggressive factor due to obstructive jaundice, biliary diversion and surgical stress might participate in occurrence of gastroduodenal ulcer after corrective surgery for BA. Peptic ulcer in infant occurs rarely, since function of gastric secretion in infancy might be still immature. Therefore, it would seem that disorder of mucosal protective factor may account for gastroduodenal ulcer in the early period after corrective surgery for BA like this patient. On the other hand, the augmentation of aggressive factor due to biliary diversion has possibly some influence upon occurrence of the ulcer formation in the late period after the operation. It is important to consider not only the esophageal varix but also the peptic ulcer as a complication of the corrective surgery for BA. And we must strive to prevent its occurrence.
