Small bowel metastasis of hepatocellular carcinoma detected by capsule endoscopy

Abstract

We report a rare case of metastasis of hepatocellular carcinoma (HCC) to the small bowel that presented as a pedunculated epithelial polyp. A 60-year-old man with liver cirrhosis type B was treated for HCC (stage IVb) at our hospital. He had been admitted for melena and anemia. Capsule endoscopy was performed in this patient with obscure gastrointestinal bleeding. It showed a polypoid lesion with bleeding in the ileum. Double-balloon endoscopy was performed. The lesion was determined to be a pedunculated polyp in the ileum. Histological examination of biopsy specimens showed tumor cells resembling HCC. We performed endoscopic mucosal resection for the lesion by double-balloon endoscopy to prevent bleeding from the tumor. The patient had no melena or anemia and his condition improved after endoscopic mucosal resection. However, he died of liver failure 2 months later. © 2013 S. Karger AG, Basel.
