Colonic metastasis from hepatocellular carcinoma after treated by ablation and transarterial chemoembolization manifested by intestinal obstruction: A case report and review of the literature

Abstract

Hepatocellular carcinoma (HCC) with gastrointestinal tract metastasis is a rare condition. Recently, we encountered one case of HCC with direct invasion to the colon, which was manifested by intestinal obstruction. The patient was an 86-year-old man who underwent multiple transarterial chemoembolization and microwave ablation treatment for HCC lesions for 10 years. Two months after last palliative microwave ablation, computed tomography showed a 7.0-cm liver tumor directly invading the hepatic flexure of colon with the symptom of right abdominal pain and discontinuous nausea and vomiting. HCC colon metastasis with intestinal obstruction was diagnosed. Intestinal adhesion lysis and colostomy were performed. The patient survived 10 months after surgery and died of tumor progression.
