A case of non-alcoholic chronic pancreatitis showing characteristic imaging features.

Differentiation between chronic pancreatitis and pancreatic cancer is often difficult. Some special types of chronic pancreatitis such as 'non-alcoholic duct-destructive chronic pancreatitis' and 'chronic pancreatitis with diffuse irregular narrowing of the main pancreatic duct' seem to be pancreatic cancer, but show imaging features characterized by the absence of parenchymal atrophy, significant ductal dilatation proximal to the site of stenosis, and the absence of extrapancreatic spread. Recognition of these special types of chronic pancreatitis prior to a definite treatment is important to avoid an unnecessary pancreatic resection. Recently, we experienced a case of non- alcoholic chronic pancreatitis in a 80-year-old man presenting with obstructive jaundice. His radiologic features were similar to those of non-alcoholic duct-destructive chronic pancreatitis. Recognition of this special type of chronic pancreatitis prior to a definitive treatment enabled us to manage this patient optimally. (Kor J Gastroenterol 2000;35:826 - 831)ope

A Case of Gastroduodenal Intussusception Secondary to Gastric Carcinoid Tumor

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 literatureope
