Figure 1. Contrast-enhanced computed tomography (CT) examination at the first (A), second (B) and third (C) laparoscopic liver resection. (A): The patient's first laparoscopic liver resection [LLR, extended segment 3 (S3) segmentectomy] was performed for two hepatocellular carcinomas (HCCs, 18 mm and 12 mm in size) in S3 and at the border of S2-3, 73 months before the fourth LLR. Contrast-enhanced CT examination (venous phase) shows two lesions (arrowheads).(B): The patient's second LLR (partial resection of S5-6) was performed for HCC (30 mm in size) on the edge of the border of S5-6, 45 months before the fourth LLR. Contrast-enhanced CT examination (portal phase) shows the lesion (arrowhead). (C): The patient's third LLR (partial resection of S7-1) was performed for a HCC (8 mm) next to the inferior vena cava, 23 months before the fourth LLR. Contrast-enhanced CT examination (portal phase) shows the lesion with lipiodol accumulation (arrowhead); this had been previously treated by trans-arterial chemo-embolization
