Abstract

Background

Minimally Invasive Liver Resection (MILR) techniques range from a hybrid-technique to full robotic approaches. When compared with open techniques, MILR has been shown to be advantageous by reducing pain, complications, length of stay and blood loss. The aim of this study was to compare clinical outcomes and hospital resource utilization between full laparoscopic, hand-assisted, and robotic liver resections among major (≥ 3 segments) and minor (≤ 2 segments) resections.

Methods

A single-center comparative retrospective review was completed on 214 patients undergoing full laparoscopic, hand-assisted, or robotic liver resection procedures between 2005 and 2018.

Results

Among minor resections: 85 full laparoscopic, 40 hand-assisted, and 35 robotic liver resection cases were analyzed; and among major resections: 13, 33, and 8 cases were analyzed, respectively. In the adjusted subgroup analysis of minor resections, OR time was significantly longer for the minor hand-assisted group (\( \bar{x} \) = 181 min; p < 0.05), and the average lesion size was smaller for the minor full laparoscopic group (\( \bar{x} \) = 4.2 cm; p < 0.05). Overall, direct hospital charges were lowest in the group of patients who underwent a minor resection using the full laparoscopic technique (\( \bar{x} \) = $39,054.90; p < 0.05), compared to the robotic technique. Due to the smaller sample size (n = 54) in the major resection subgroup, only two significant observations were made - the full laparoscopic group had the least amount of blood loss (\( \bar{x} \) = 227 cc; p < 0.05) and incurred the least amount of room and board charges compared to the other two techniques.

Conclusions

The robotic approach appears favorable for minor resections as evidenced by shorter length of stay but more costly than full laparoscopy. Clinical outcomes appear to be more dependent upon the magnitude of the resection (i.e. major vs. minor) than the MILR technique chosen. Randomized trials may be indicated to discern the best indications and advantages of each technique.
