A Case of Gastric Carcinoma Spread to the Duodenum / 대한소화기내시경학회지

In 1861 Rokitanski laid down the law that the pyloric ring served as a barrier to the duodenal spread of gastric cancer. Although this theory was generally accepted, direct spread of gastric carcinoma into the duodenum has been reported. We report a case of gastric cancer spreading into the duodenum that was diagnosed by endoscopic duodenal biopsy and review the literature.
