Laparoscopic hepatectomy is safely performed with minimal invasiveness on patients with recurrent liver tumors after previous hepatectomy. However, it is still difficult to dissect and expose the operative field at the transected edge or plane after open right hepatectomy, even for limited resection by a laparoscopic approach, due to severe adhesion to the surrounding peritoneum or organs. We herein applied the retroperitoneal laparoscopic approach to limited resection of the dorsal surface at the transected edge of Couinaud's segment 6 after previous repeated hepatectomies in a patient with recurrent hepatocellular carcinoma (HCC) by avoiding severe intra-abdominal adhesion. We safely resected recurrent HCC via the retroperitoneal space. This approach is a useful and alternative option for laparoscopy which minimizes the dissecting time and avoids organ injury on the right side of the transected area of the liver after hepatectomy in patients with liver malignancies.
