- Abstract
- BACKGROUND: The role of minimally invasive right anterior and right posterior sectionectomy (MI-RAS/ MI-RPS) for right-sided liver lesions remains debatable. Although technically more demand-ing, these procedures might result in faster recovery and lower postoperative morbidity com-pared with minimally invasive right hemihepatectomy. STUDY DESIGN: This is an international multicenter retrospective analysis of 1,114 patients undergoing mini-mally invasive right hemihepatectomy, MI-RAS, and MI-RPS at 21 centers between 2006 and 2019. Minimally invasive surgery included pure laparoscopic, robotic, hand-assisted, or a hybrid approach. A propensity-matched and coarsened-exact-matched analysis was performed. RESULTS: A total of 1,100 cases met study criteria, of whom 759 underwent laparoscopic, 283 robotic, 11 hand-assisted, and 47 laparoscopic-assisted (hybrid) surgery. There were 632 right hemihepatecto-mies, 373 right posterior sectionectomies, and 95 right anterior sectionectomies. There were no dif-ferences in baseline characteristics after matching. In the MI-RAS/MI-RPS group, median blood loss was higher (400 vs 300 mL, p = 0.001) as well as intraoperative blood transfusion rate (19.6% vs 10.7%, p = 0.004). However, the overall morbidity rate was lower including major morbidity (7.1% vs 14.3%, p = 0.007) and reoperation rate (1.4% vs 4.6%, p = 0.029). The rate of close/involved margins was higher in the MI-RAS/MI-RPS group (23.4% vs 8.9%, p < 0.001). These findings were consistent after both propensity and coarsened-exact matching. CONCLUSIONS: Although technically more demanding, MI-RAS/MI-RPS is a valuable alternative for min-imally invasive right hemihepatectomy in right-sided liver lesions with lower postopera-tive morbidity, possibly due to the preservation of parenchyma. However, the rate of close/ involved margins is higher in these procedures. These findings might guide surgeons in preop-erative counselling and in selecting the appropriate procedure for their patients. (C) 2022 by the American College of Surgeons.
