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.
