    Abstract:
    BACKGROUND: Presently, the adoption of laparoscopic hepatectomy is rapidly increasingly worldwide. However, the application of robotic hepatectomy (RH) remains limited and its role remains undefined today. METHODS: A retrospective review of 43 consecutive patients who underwent RH at two institutions in the Singapore Health Services Group. RESULTS: Forty-three consecutive patients underwent 48 resections during the study period. Seven (16.3%) patients underwent major resections and seven (16.3%) underwent right posterior sectionectomies. Nineteen (44.2%) patients had tumours located in the difficult posterosuperior segments, five had multiple resections and three underwent repeat resections for recurrent tumours. RH was performed for malignant tumours in 32 (74%) patients and 16 (37.2%) had cirrhosis. Seven RH was performed with other concomitant procedures including three colectomies, three hilar lymphadenectomies and one portal vein ligation. The median operation time was 360 min (range 75-825) and the median blood loss was 300 mL (range 25-4500). There was one (2.3%) open conversion for bleeding. The median post-operative stay was 4 days (range 2-33) and there was one (2.3%) readmission. There was one (2.3%) major (>grade 2 morbidity) in a patient with concomitant anterior resection who underwent reoperation for anastomotic leak. There was no 90 day/in-hospital mortality. Comparison between RH for tumours in the anterolateral segments versus posterosuperior segments demonstrated no significant difference in perioperative outcomes. CONCLUSION: Our initial experience demonstrated that RH is safe, feasible and associated with excellent post-operative outcomes. It can be performed successfully with low morbidity even for complex resections such as major hepatectomies, posterior sectionectomies, tumours in difficult posterosuperior segments and repeat liver resections.
