Description
Roberta Vella and a large team of co-authors published this 2026 study of the first robotic liver operations of one surgeon. Robotic removal of liver tumors is spreading fast, but how skill grows with case difficulty at mid-size centers is poorly charted. The team reviewed 58 straight cases from a single surgeon at such a center.
Most operations were minor resections, and only two rated expert-level hard on a standard score. Median blood loss was 100 milliliters, about one case in ten converted to open surgery, and no patient died within ninety days. Textbook outcomes, a bundle of ideal results, were met in 69 percent of cases by one definition. Running-total charts traced how results shifted from the earliest cases to the latest.
