Abstract
Background
Transection along the anterior fissure was proposed as a mechanism by which to open the third door of the liver. In this study, we investigated surgical outcomes of a ventral segment-preserving right hepatectomy (VSPRH) compared with those of conventional right hepatectomy in patients with hepatocellular carcinoma (HCC).
Methods
Between January 2007 and December 2010, 595 primary HCC patients underwent liver resection at the authors’ institution. Among them, the 123 HCC patients who underwent a right hepatectomy were retrospectively analyzed. The patients were classified into two groups according to the type of resection: those who underwent a VSPRH (Group A; 27 cases) and those who underwent a conventional right hepatectomy (Group B; 96 cases).
Results
In Group A, expected remnant liver volume after a right hepatectomy was calculated to be 32.1 ± 7.2 % of functional total liver volume (FTLV); remnant liver volume increased up to 54.7 ± 7.2 % of FTLV after a VSPRH. Clinicopathologic characteristics and intraoperative data did not differ between the two groups. The liver-related complication rate was higher in Group B (P = 0.02). Overall survival and disease-free survival rates were similar (3-year disease-free survival (Group A: 67.8 %; Group B: 71.7 %; P = 0.65); 3-year overall survival (Group A: 91.7 %; Group B: 87.4 %; P = 0.26). In regard to long-term synthetic function, the 1-year postoperative serum albumin level was higher in Group A.
Conclusions
A VSPRH yielded fewer liver-related complications and similar long-term oncologic outcomes, compared with conventional right hepatectomy in cirrhotic patients with a small left lobe volume. Therefore, VSPRH can be considered to be an alternative procedure for a right hepatectomy.
