Thoracoabdominal approaches versus inverted T incision for posterior segmentectomy in hepatocellular carcinoma

Background/Aims: The purpose of the present study was to clarify the indications for a thoracoabdominal right oblique approach and an inverted L incision in posterior segmentectomy of the liver for hepatocellular carcinoma. Methodology: Forty-six patients with hepatocellular carcinoma who underwent posterior segmentectomy with thoracotomy were divided into 2 groups according to the incision: thoracoabdominal right oblique incision (group A, n=17) and inverted L incision (group B, n=29). The perioperative factors of the patients in the 2 groups were compared retrospectively. Results: No significant differences were found in the preoperative factors between the groups. However, a longer operation time (P=0.01) and more blood loss (P=0.02) were noted in group B. Although there was no significant difference between the groups in the overall morbidity rate (P=0.36), a higher rate of pleural effusion was recognized in group A (P=0.01). Conclusions: Thoracoabdominal right oblique incision may be suitable for use as an approach for posterior segmentectomy when manipulation of the left lobe is not required.
