腹腔镜肝切除手术设定了全球基准截止值：左侧肝切除术、左侧肝切除术和右侧肝切除术。我们的目的是将我们北美中心的表现与既定的全球基准进行比较。这是一项针对 2010 年至 2022 年在多伦多综合医院接受腹腔镜肝切除术的成年人的单中心研究。评估了 14 项基准结果：手术时间、术中输血、估计失血量、失血量≥500 mL、失血量≥1000mL、开放转场、术后住院时间、恢复手术、术后发病率、术后主要发病率、30天死亡率、90 天死亡率、R1 切除和抢救失败。低风险基准病例定义为：年龄18～70岁、美国麻醉医师协会评分≤2、肿瘤大小<10cm、Child-Pugh评分≤A。涉及胆肠吻合术、肺门解剖或伴随的重大手术的病例被排除在低风险类别之外。不符合低风险选择标准的病例被视为高风险病例。共分析178例腹腔镜肝切除病例（左侧侧切109例，左侧肝切除45例，右侧肝切除24例）。 44 例 (25%) 病例符合低风险病例（23 例左侧肝切除术、16 例左肝切除术、5 例右肝切除术）。低危病例行左侧侧叶切除、左侧肝切除和右侧肝切除后，术后主要发病率和90天死亡率分别为0%、0%和0%，以及0%、0%和0%。对于2017年后的高风险病例，结果按相同顺序分别为0%、0%和12%；分别为 0%、0% 和 0%。对于2017年之前手术的高风险病例，结果的顺序相同，分别为9%*、16%*和18%；分别为 2%*、0% 和 9%*（星号表示未达到全球截止值）。北美中心能够实现与腹腔镜肝切除术全球既定基准相当的结果。版权所有 © 2023 Elsevier Inc 。 版权所有。

The global benchmark cut-offs were set for laparoscopic liver resection procedures: left lateral sectionectomy, left hepatectomy, and right hepatectomy. We aimed to compare the performance of our North American center with the established global benchmarks.This is a single-center study of adults who underwent laparoscopic liver resection between 2010 to 2022 at the Toronto General Hospital. Fourteen benchmarking outcomes were assessed: operation time, intraoperative blood transfusion, estimated blood loss, blood loss ≥500 mL, blood loss ≥1000mL, open-conversion, postoperative length of stay, return to operation, postoperative morbidity, postoperative major-morbidity, 30-day mortality, 90-day mortality, R1 resection, and failure to rescue. Low-risk benchmark cases were defined as follows: patients aged 18 to 70 years, American Society of Anesthesiologist score ≤ 2, tumor size <10 cm, and Child-Pugh score ≤A. Cases involving bilio-enteric anastomosis, hilar dissection, or concomitant major procedures were excluded from the low-risk category. Cases that did not meet the criteria for low-risk selection were considered high-risk cases.A total of 178 laparoscopic liver resection cases were analyzed (109 left lateral sectionectomies, 45 left hepatectomies, 24 right hepatectomies). Forty-four (25%) cases qualified as low-risk cases (23 left lateral sectionectomies, 16 left hepatectomies, 5 right hepatectomies). The postoperative major morbidity and 90-day mortality after left lateral sectionectomy, left hepatectomy, and right hepatectomy for the low-risk cases were 0%, 0%, and 0%, and 0%, 0%, and 0%, respectively. For the high-risk cases post-2017, the outcomes in the same order were 0%, 0%, and 12%; 0%, 0%, and 0%, respectively. For the high-risk cases operated pre2017, the outcomes in the same order were 9%∗, 16%∗, and 18%; 2%∗, 0%, and 9%∗ (asterisks indicate not meeting the global cut-off), respectively.A North American center was able to achieve outcomes comparable to the established global benchmark for laparoscopic liver resection.Copyright © 2023 Elsevier Inc.
