Robot-assisted minimally invasive esophagectomy (RAMIE) is increasingly adopted in centers worldwide, with ongoing refinements to enhance results. This study aims to assess the current state of RAMIE worldwide and to identify potential areas for improvement.
This descriptive study analyzed prospective data from esophageal cancer patients who underwent transthoracic RAMIE in Upper GI International Robotic Association (UGIRA) centers. Main endpoints included textbook outcome rate, surgical techniques, and perioperative outcomes. Analyses were performed separately for intrathoracic (Ivor-Lewis) and cervical anastomosis (McKeown), divided into three time cohorts (2016-2018, 2019-2020, 2021-2023). A sensitivity analysis was conducted with cases after the learning curve (> 70 cases).
Across 28 UGIRA centers, 2012 Ivor-Lewis and 1180 McKeown procedures were performed. Over the time cohorts, textbook outcome rates were 39%, 48%, and 49% for Ivor-Lewis, and 49%, 63%, and 61% for McKeown procedures, respectively. Fully robotic procedures accounted for 66%, 51%, and 60% of Ivor-Lewis procedures, and 53%, 81%, and 66% of McKeown procedures. Lymph node yield showed 27, 30, and 30 nodes in Ivor-Lewis procedures, and 26, 26, and 34 nodes in McKeown procedures. Furthermore, high mediastinal lymphadenectomy was performed in 65%, 43%, and 37%, and 70%, 48%, and 64% of Ivor-Lewis and McKeown procedures, respectively. Anastomotic leakage rates were 22%, 22%, and 16% in Ivor-Lewis cases, and 14%, 12%, and 11% in McKeown cases. Hospital stay was 13, 14, and 13 days for Ivor-Lewis procedures, and 12, 9, and 11 days for McKeown procedures. In Ivor-Lewis and McKeown, respectively, the sensitivity analysis revealed textbook outcome rates of 43%, 54%, and 51%, and 47%, 64%, and 64%; anastomotic leakage rates of 28%, 18%, and 15%, and 13%, 11%, and 10%; and hospital stay of 11, 12, and 12 days, and 10, 9, and 9 days.
This study demonstrates favorable outcomes over time in achieving textbook outcome after RAMIE. Areas for improvement include a reduction of anastomotic leakage and shortening of hospital stay.
机器人辅助微创食管切除术（RAMIE）在全球各中心的应用日益广泛，并且在持续改进以提高手术效果。本研究旨在评估全球范围内RAMIE的现状，并确定潜在的改进领域。
这项描述性研究分析了在上消化道国际机器人协会（UGIRA）中心接受经胸RAMIE的食管癌患者的前瞻性数据。主要终点包括教科书式结局率、手术技术和围手术期结局。对胸内（艾弗-刘易斯）和颈部吻合（麦基翁）分别进行分析，并分为三个时间队列（2016 - 2018年、2019 - 2020年、2021 - 2023年）。对学习曲线之后（>70例）的病例进行了敏感性分析。
在28个UGIRA中心，共进行了2012例艾弗-刘易斯手术和1180例麦基翁手术。在各个时间队列中，艾弗-刘易斯手术的教科书式结局率分别为39%、48%和49%，麦基翁手术的教科书式结局率分别为49%、63%和61%。全机器人手术在艾弗-刘易斯手术中分别占6
