Surgical treatment of hepatocellular carcinoma after Fontan operation: three case reports and review of the literature.

We herein describe three patients with Fontan-associated liver disease who developed hepatocellular carcinoma (HCC). The first patient was a 28-year-old woman who had undergone the Fontan operation (FO) at the age of 4 years. She was diagnosed with HCC (cT4aN0M0, Stage IVA, UICC 8th edition), for which she underwent extended posterior right sectionectomy and partial hepatectomy of S2. She developed recurrence of peritoneal dissemination after 12 months, and she was alive 18 months after surgery. The second patient was a 43-year-old man who had undergone the FO at the age of 3 years. He was diagnosed with HCC (cT2N0M0, Stage II), for which he underwent laparoscopic-assisted partial hepatectomy of S3. He remained free from recurrent HCC for 17 months. The third patient was a 21-year-old woman who had undergone the FO at the age of 3 years. She was diagnosed with HCC (cT3N0M0, Stage III), for which she underwent laparoscopic-assisted partial hepatectomy of S2 and S4. She remained free from recurrent HCC for 30 months. We reviewed 18 surgical cases of HCC arising from Fontan-associated liver disease, including our 3 cases, and found that a high preoperative alpha-fetoprotein concentration might be a predictor of HCC recurrence.
