Hand-Assisted Laparoscopic Hepatectomy for Primary Clear Cell Hepatocellular Carcinoma of the Liver

摘要

We report a case of primary clear cell hepatocellular carcinoma of the liver (PCCCL) for which we performed hand-assisted laparoscopic hepatectomy. A 71-year-old female with hepatitis C infection and diabetes mellitus was admitted to our department for a hepatic tumor with gallstone. Abdominal computed tomography revealed a tumor 25 mm in diameter on the surface in segment 5 of the liver. The imaging results suggested small hepatocellular carcinoma located on the surface in segment 5 of the liver, and we performed laparoscopic surgery aiming at a minimally invasive procedure. We performed laparoscopic cholecystectomy and hand-assisted laparoscopic hepatectomy. Histopathological findings showed moderately differentiated hepatocellular carcinoma, and as the proportion of clear cells was 75%, the tumor was diagnosed as PCCCL. This is the first report of hand-assisted laparoscopic hepatectomy for PCCCL. Laparoscopic hepatectomy is a useful minimally invasive surgical procedure when the tumor is located on the surface of the liver.
