Introduction : Laparoscopic liver resection (LLR) has required the specialized techniques and knowledge for laparoscopic and hepatobiliary surgery. Because there are lack of experience and indications, generally most hospitals have not much of cases for LLR except some large-volume center. I introduce my inchoate experiences for LLR based on retrospective study.

Methods : Data from 41 LLRs conducted from 2017 were retrospective collected during 3 years. Mean age of patients was 59.1 ± 12.4 (24 – 82) years old. One patient developed controlled ascites by diuretics. All cases were performed single specialized hepatobiliary surgeon in single center.

Results : Among 41 LLRs, 14 cases of major liver resections including 6 cased of right hemihepatectomy were performed for hepatocellular carcinoma, metastatic tumor and intrahepatic duct stone and benign hepatic masses. There are 39 cases were performed by pure laparoscopic procedure and open conversion was performed in 1 patients (2.4%). Average difficulty score for LLR was 6.4 (3 - 10) points. Mean operative time was 310.0 ± 137.4 minutes and mean postoperative length of stay was 11.1 ± 3.7 days. Estimated blood loss during operation was 490.3 ± 255.6 mL and there was no patient required intraoperative transfusion. There were 32 patients who had single tumor (78.0%) and mean maximal size of resected tumors was 3.71 ± 3.45 cm. Overall survival revealed 304.1 ± 209.5 days and only a patient had passed away due to disease

Conclusions : LLR has become a reliable option and can achieve better outcomes by continuous surgical training and experience.
