위유암종에 의해 유발된 위십이지장중첩증 1 예

Gastroduodenal intussusception is a rare condition caused by the prolapse of a gastric tumor and subsequent invagination of the gastric wall into the duodenum. The lead point of the intussusception is usually a benign gastric tumor such as adenoma, lipoma, and leiomyoma. Only a small number was attributed to gastric carcinoma, giant solitary gastric heterotopia, Menetrier's disease, and Peutz-Jeghers syndrome. In Korea, only two cases of gastroduodenal intussusception caused by adenoma and by leiomyoma have been reported. We experienced a case of gastroduodenal intussusception caused by gastric carcinoid tumor in a 76-year-old woman. Interestingly, she had been diagnosed as having gastric carcinoid tumor metastasized to the liver 5 years and 3 months before this gastroduodenal intussusception occurred. This rare clinical setting of gastroduodenal intussusception by a rare cause is reported with a review of the literature. (Korean J Gastroenterol 2001;38:288-291)
