  ABSTRACT: The purpose of this study was to evaluate the possibility of expanding the selection criteria in living donor liver transplantation (LDLT) to treat hepatocellular carcinoma (HCC). From October 2000 to December 2010, we retrospectively analyzed 71 patients who had undergone LDLT beyond the Milan criteria (MC), among the entire cohort of 199 HCC patients. We evaluated the tumor biology as well as overall and disease-free survival (DFS), seeking to identify risk factors for recurrence. The median follow-up was 37 months (range 5-124). Among the 71 patients beyond the MC were 18 recurrences and 30 deaths. Their 5-year overall and DFS rates were 52.3% and 67.7%, respectively. On multivariate analysis, tumor diameter, tumor number, and E-S grade significantly influenced overall and DFS. According to our new criteria (size≤7 cm, number≤7), 86% of our patients would be included compared with 64% using MC. Five-year DFS and overall survival rates according to our criteria were comparable with the MC: 86.8% and 72.3% versus 86.8% and 73.4%, respectively. Our criteria appear to achieve useful cut-off values beyond the MC.

  ABSTRACT: Single-port laparoscopic (SPL) surgery has rapidly gained attention worldwide. Since May 2008, we have propagated the use of SPL surgery, mainly for cholecystectomy and appendectomy. Recently, we have used this modality of minimally invasive surgery for various liver surgeries. We hereby discuss our outcomes of SPL-assisted donor right hepatectomies. The preoperative workup is the same as for a standard donor hepatectomy. We retrospectively reviewed the data of 150 patients who underwent donor right hepatectomy from October 2008 to May 2011. We divided them into 3 groups depending on the type of surgical procedure. Among 150 patients, 20 underwent laparoscopy-assisted donor right hepatectomy (LADRH); 40 underwent single-port laparoscopy-assisted donor right hepatectomy (SPLADRH); and 90 underwent open donor right hepatectomy (ODRH). The donor demographics were comparable among the groups. Postoperative complication and reoperation rates revealed no significant differences. The SPLADRH group showed the lowest level of postoperative pain, thereby leading to a better quality of life postoperatively. SPLADRH seems to be a simple, feasible approach.
