title: Short-term Outcomes of Laparoscopic Versus Open Right Hemihepatectomy for Hepatocellular Carcinoma.
abstract: BACKGROUND
  Laparoscopic liver resection for hepatocellular carcinoma (HCC) is performed in a relatively small number of institutions. Its operative results have been reported to be comparable with that of open laparotomy; however, information on laparoscopic right hemihepatectomy (LRH) is scarce. This study aimed to compare the perioperative outcomes of the right hemihepatectomy via laparoscopic and open approach to treat HCC at a single institution.
  
  
  METHODS
  From January 2010 to 2015, we performed right hemihepatectomy in 77 HCC patients. LRH was performed in 35 patients and open right hemihepatectomy (ORH) was performed in 42 patients. All clinical data were analyzed retrospectively.
  
  
  RESULTS
  The mean LRH operative time was longer than ORH (309±108 vs. 223±110 min; P<0.02). The median blood loss for the LRH was 293±82.5 mL compared with 433±105.5 mL for the ORH, showing a highly significant difference. Length of hospital stay was shorter in LRH patients compared with those following ORH (9±2 vs. 15±3 d; P<0.05). The postoperative morbidity rate was also significantly different between the groups, a tendency toward more severe complications in the ORH group compared with LRH group.
  
  
  CONCLUSIONS
  LRH can decrease complications, shorten hospitalization time, is a minimally invasive, safe, and effective way.
