Outcomes of Laparoscopic Left Lateral Sectionectomy vs. Open Left Lateral Sectionectomy: Single Center Experience

Abstract

Purpose: Laparoscopic surgery has become the mainstream surgical operation due to its stability and feasibility. Even for liver surgery, the laparoscopic approach has become an integral procedure. According to the recent international consensus meeting on laparoscopic liver surgery, laparoscopic left lateral sectionectomy (LLS) might be a new standard of care for left lateral surgical lesions. This study was designed to compare open LLS to laparoscopic LLS. Methods: In total, 82 patients who had undergone LLS at Chonnam National University HwasunHospital between 2008 and 2015 were enrolled in this study. Among them, 59 patients underwent open LLS and 23 underwent laparoscopic LLS. These two groups were compared according to general characteristics and operative outcomes. Results:The data analysis results showed that laparoscopic liver resection is superior to open liver resection in terms of the amount of bleeding during the operation and the duration of hospital stay. There was no statistical difference between the two groups in terms of operation time (p value=0.747). The amount of bleeding during the operation was 145.5±149.4 ml on average for the laparoscopic group and 320±243.8 ml on average for the open group (p value=0.005). The mean duration of hospital stay was 10.7±5.8 days for the laparoscopic surgery group and 12.2±5.1 days for the open surgery group (p value=0.003). Conclusion:This study showed that laparoscopic LLS is safe and feasible, because it involves less blood loss and a shorter hospital stay. For left lateral lesions, laparoscopic LLS might be the first option to be considered.
