Abstract
Background Laparoscopic major hepatectomies remain a challenge for liver surgeons. The recent introduction of robotic surgical systems has revolutionized the field of minimally invasive surgery. It was developed to overcome the disadvantages of conventional laparoscopic surgery. The use of robotic system in laparoscopic major hepatectomy was not known yet. Methods Between December 2010 and July 2011, 6 right hemi-hepatectomies and 4 left hemi-hepatectomies were performed by robot-assisted laparoscopic approach. Prospectively collected data was analyzed retrospectively. Results Overall mean duration of the operation was 347.4 ± 85.9 (SD) minutes. Mean duration of the operation for right hemi-hepatectomy was 364.8 ± 98.1 ml, while mean duration of the operation for left hemi-hepatectomy was 321.3 ± 67.8 ml. Overall mean operative blood loss was 407 ± 286.8 ml. Mean operative blood loss for right hemi-hepatectomy was 500 ± 303.3 ml, while mean operative blood loss for left hemi-hepatectomy was 156.9 ± 40.7 ml. No open conversion was needed. Three patients (30%) had postoperative complications. There was no mortality. Mean hospital stay was 6.7 ± 3.5 days. Conclusions Our series indicate that in experienced hands, robot-assisted laparoscopic approach for hemi-hepatectomy is feasible and safe. As experience grows, this procedure will be more common.
