title: Outcomes After Laparoscopic Hepatectomy in the Semi-prone Position for Hepatocellular Carcinoma Located in Segment 6, 7, or 8.
abstract: BACKGROUND
  This retrospective study investigated outcomes after laparoscopic hepatectomy in the semi-prone position compared to open hepatectomy in the conventional supine position, for HCC (hepatocellular carcinoma) located in segment 6, 7, or 8.
  
  
  METHODS
  Patients were divided into two groups according to the surgical approach. The clinicopathological and surgical outcomes were analyzed.
  
  
  RESULTS
  There were no significant differences in patient-related or tumor-related factors between the two groups. The laparoscopic-hepatectomy group had significantly less blood loss, fewer postoperative complications, and a shorter hospital stay than the open-hepatectomy group. There were no in-hospital deaths. The postoperative change in the serum C-reactive protein was a significantly larger decrease in the group treated with laparoscopic hepatectomy than that in the open-hepatectomy group.
  
  
  CONCLUSIONS
  Laparoscopic hepatectomy in the semi-prone position for HCC is safe and minimally invasive, and can reduce intraoperative bleeding, postoperative complications, and hospital stay compared to open hepatectomy.
