An abdominal computed tomography scan showed a hepatic metastasis measuring 45 mm in segments 2/3 of the liver (Fig. 1), thickening of the ascending colonic wall and swelling of the regional lymph nodes.
(A) The surgical trocar sites. The dotted line indicates the incision line used for the hand-assisted laparoscopic procedure, which was 7-cm long. (B) Liver schema. Arrowhead, a tumor measuring 5 mm was found in the right hepatic lobe (segment 7); Double arrowhead, another tumor was detected in the right hepatic lobe (segment 6); Arrow, a third metastatic tumor was observed in the left hepatic lobe (segments 2/3).

Trocars were inserted at the locations shown in Fig. 2A. Laparoscopic left lateral segmentectomy was carried out for the hepatic metastasis in the left lobe of the liver, and partial resection of the liver was conducted for the hepatic metastasis in segment 6 of the liver (Fig. 2B). The remaining hepatic metastasis in segment 7 of the liver was treated with hand-assisted radiofrequency ablation (RFA) because the tumor was tiny, and it was difficult to approach it (Fig. 2B).
