A Comparative Study of Laparoscopic and Open Approaches for Right Hemihepatectomy in Hepatocellular Carcinoma Patients: Safety and Short-Term Outcomes.

ABSTRACT

BACKGROUND Hepatocellular carcinoma (HCC) is a leading cause of cancer deaths worldwide, with China reporting over half of global cases. While traditional open liver resection is effective, it often results in large incisions and significant complications. Laparoscopic hepatectomy, particularly for right hemi-hepatectomy, features smaller incisions and quicker recovery, but its widespread adoption is hindered by its procedural complexity and a steep learning curve. This study compares the safety and efficacy of laparoscopic versus open right hemi-hepatectomy with an anterior approach in 57 patients with HCC. MATERIAL AND METHODS The data of patients with HCC who underwent treatment at our center from January 2016 to December 2020 were retrospectively analyzed. RESULTS We included a total of 57 patients with histopathologically-confirmed HCC - 23 in the laparoscopic group and 34 in the open group. Operation time was significantly shorter in the open group than in the laparoscopic group (234.5±66.9 vs 297.0±74.9, P=0.002). Intraoperative bleeding was significantly less in the laparoscopic group (P=0.042). There were no statistically significant differences in postoperative complications between the 2 groups. Postoperative hospital stay was significantly shorter in the laparoscopic group (12 days vs 15 days, P=0.044). There was no significant difference in postoperative overall survival (OS) and disease-free survival (DFS) between the 2 groups (P>0.05). CONCLUSIONS In patients with hepatocellular carcinoma, the laparoscopic right hemi-hepatectomy with the anterior approach technique has the same safety and comparable short-term outcomes as open surgery.
