The effect of the robotic platform in hepatectomy after prior liver and non-liver abdominal operations: a comparative study of clinical outcomes
Tóm tắt
Improvements in outcomes after primary hepatectomy have increased the eligibility of patients for reoperative hepatectomies, but this can be fraught with technical difficulties, particularly via a minimally invasive approach. The robotic approach provides superior visualization, articulated instrumentation, platform stability, and increased dexterity when compared to conventional laparoscopy. We sought to investigate the effect brought by the robotic system in the outcome of these operations. We followed 234 patients who underwent robotic liver resection from 2012 to 2021 for retrospective analysis. Patients were classified as: no prior abdominal operation, prior abdominal operation(s), and prior liver resection. Cohorts were compared by one-way ANOVA and 2 × 3 contingency table analyses. For illustrative purposes, data are presented as median (mean ± SD). Significance was accepted at p < 0.05. Of the 234 patients studied, 114 underwent primary hepatectomy, 105 had a prior laparoscopic or open abdominal operation (cholecystectomy, herniorrhaphy, colectomy, and appendectomy), and 15 had a redo hepatectomy. Demographic and preoperative ASA, MELD, neoplasm size, and extent of liver resection were similar among the cohorts. There were no statistically significant differences between the three cohorts for all outcome variables including blood loss, operative duration, intensive care unit length of stay, overall length of stay, morbidity, mortality, and readmission rate. There were no differences in morbidity nor mortality between patients undergoing primary nor reoperative robotic hepatectomy. The advantages afforded by the robotic platform may have contributed to the equalization of outcomes.
