Abstract

To compare textbook outcomes (TO) of open live donor right hepatectomy (RH) versus open right hepatic lobectomy for cancer in a single Western center, and to identify clinical factors associated with failure to achieve a TO. TO, a composite quality measure that captures multiple aspects of peri-operative care, has not been thoroughly studied in open RH. We hypothesized that TO rates after RH for live donor transplant could represent the "best-achievable" results of this operation and could serve as the benchmark for RH performed for an oncologic indication. A prospective database was reviewed to compare TO rates after RH for live donor purposes versus RH for cancer at a single center from 2010-2020. A TO was defined as achieving 7 metrics: no peri-operative transfusion, no major postoperative complications, no significant bile leak, no unplanned transfer to the ICU, no 30-day mortality, no 30-day re-admission, and no R1 margins for cancer cases. Amongst 686 RH patients (371 live donor and 315 cancer cases), a TO was achieved in 92.2% of RH donors and 53.7% of RH cancer cases. Live donor patients tended to be younger, healthier, and thinner. Amongst donors, increased intra-operative blood loss, and in cancer cases, male gender, tumor size, and increased intra-operative blood loss were associated with TO failure. A TO can be achieved in over 90% of patients undergoing living donor RH and in approximately half of RH cancer cases. These metrics represent a new benchmark for "real-world" TO after open RH.
