LiverRobotic major hepatectomy: Is there a learning curve?
Section snippets
Methods
This was a retrospectively designed study from the review of the medical records. All procedures were approved by the institution's supervisory committee, and this study was approved by the institutional review board. All procedures were performed by the same operative team.
Major hepatectomy was defined as the resection of ≤3 contiguous Couinaud segments. All consecutive patients who underwent RMH at our hospital between January 2012 and October 2015 were selected for the study. Patients with
Results
During the study period, >50% of the 183 patients who underwent robotic hepatectomy had major procedures (Table I). For the 92 patients who underwent RMH, the median age was 53 years (range 19–87 years); there were 53 men and 39 women. Regarding RMH, hepatocellular carcinoma was accounted for the majority (60%) of overall indications. All patients with malignant disease underwent histopathologically proven R0 resection, with no evidence of cancer in the resection margins. Among the procedures
Discussion
In our review of minimally invasive major hepatectomies, few documents regarding laparoscopic major hepatectomy of a single institute have been reported, including 96 cases from Koffron et al,22 62 cases from Buell et al,23 and 173 cases from Nomi et al.14 However, the adoption of minimally invasive major liver resection in clinical practice has been gradual; the worldwide trend has increased slowly from 16–22% during the past 5 years.24, 25 Although inherited from conventional laparoscopy,
