Background: The technique for liver resection of a caudate lobe lesion requires skill because the area is located deep in proximity with the great vessels The laparoscopic approach has made resection of tumor in the caudate lobe easier. The aim of this study was to assess the superiority and safety of the laparoscopic approach for hepatoma in the caudate lobe in comparison with the open approach.
Method: Between 2008 and 2016, 9 patients who underwent laparoscopic liver resection (LLR) for hepatoma in the caudate lobe (LLR group) were compared with 11 patients who underwent open liver resection for hepatoma in the caudate lobe (OLR group). Patient background, characteristics, and perioperative outcomes were compared.
Results: All patients in the LLR group and 5 in the OLR group were diagnosed with hepatocellular carcinoma, and 6 in the OLR group had metastatic liver tumor. There were no other significant differences in patient background. Operative duration was similar for these groups. Blood loss and hospital stay in the LLR group (50 ml, 4.5 days) were significantly lesser than in the OLR group (435 ml, 8 days) (p=0.0110, p=0.0011). Tumor exposure ratio at the surgical margin was similar between the groups.
CONCLUSION: The laparoscopic approach in the caudate lobe is a safe and less invasive procedure in selected patients.
