Background : Laparoscopic liver resection is still challenging surgery for novice liver surgeon. Many studies reported minimum require number for overcoming learniing curve of LLS as from 20 to 60 cases. We investigated 2nd generation laparoscopic novice liver surgeon in fledgling medical center.

Methods : From Mar 2020 to December 2023, total 149 patients underwent liver resection . Among them, 66 patients received laparoscopic liver resection. We compared perioperative outcomes between laparoscopic and open liver resection groups.

Results : In laparoscopic resection groups, extent of resection as segmentectomy and morethan 2 segmentectomy were 33.4% . However, in open resection group, more than 2 segmentectomy extent was 56.6%. There were no significant differences in terms of sex, age, BMI between two groups. Laparoscopic liver resection group showed significant shorter length of hospital stay days( 9.3 ± 3.4 vs. 14.1 ± 6.8, p=0.004 ) and lower estimated blood loss than open resection group (498.2 ± 680.8 vs. 939.2 ± 559.0, p = 0.025) Tumor size in laparoscopic resection group was significantly smaller than open resectio group. ( 1.9 ± 1.5 vs. 3.8 ± 2.2 , p= 0.008). In comparison of posteropative complications, there were no siginificant differences betwee two groups.

Conclusions : The initial outcomes of laparoscopic liver resection in the fledgling center is mainly resection in minor areas, however there is no significant difference from the open group in terms of perioperative outcome, so it should be attempted actively.
