Introduction : Robotic hepatectomy has been suggested as a safe and effective management of liver disease including malignancy. In current study, we report our initial experience with robotic left side hepatectomy.

Methods : A retrospective review of a prospective database of 26 consecutive patients who underwent robotic hepatectomy at a single institution by single surgeon was conducted. Twelve consecutive patients who underwent robotic left-side hepatectomy from June 2016 to January 2018, were identified and we analyzed their perioperative outcomes.

Results : The disease included 4 hepatocellular carcinoma (HCC), 4 metastatic cancer to liver, 1 combined HCC and cholangiocarcinoma(CCC), 2 intrahepatic CCC and 1 peribilary cyst. The procedure included 7 left hemi-hepatectomies and 5 left lateral sectionectomies (two including single site incision). The median tumor size was 32.5 (range, 12-81) millimeters and all patients had tumor free resection margin. The median totally duration of surgery (skin to skin) of all patients was 205.5 (range, 105-295) minutes and each median totally duration of surgery of left hemi-hepatectomy and left lateral sectionectomy was 263 and 165 minutes, respectively. The median length of postoperative hospital stay was 6 (range, 5-10) days. None of patients had transfusion. There is no open conversion and also no any postoperative in hospital complications and mortalities.

Conclusions : Our initial experience confirms the feasibility and safety of robotic left side hepatectomy.
