Abstract

Robotic surgery has emerged as a promising alternative to traditional approaches, offering enhanced precision and ergonomics. However, its application to pancreaticoduodenectomy (PD) remains controversial due to technical complexity and a steep learning curve. This study aims to evaluate the perioperative outcomes of robotic versus open PD at a single high-volume center, using inverse probability of treatment weighting (IPTW) to control for confounding variables. : A retrospective, single-center analysis was conducted on patients who underwent PD between January 2020 and December 2024. Perioperative and oncological outcomes were compared using IPTW, aiming to balance potential confounding variables. The primary endpoint was 90-day postoperative mortality; secondary endpoints included operative time, estimated blood loss, major postoperative complications (Clavien-Dindo grade ≥ IIIa), and length of hospital stay. : Seventy-four patients were included in the intention-to-treat analysis (open: = 31; robotic: = 43). After IPTW adjustment, baseline characteristics were balanced across the groups. Operative time was significantly longer in the robotic group (median 540 vs. 479 min, = 0.009). No significant differences were observed in 90-day mortality (4.9% both groups, = 0.998), postoperative complications ≥ IIIa, or histopathological outcomes, including R0 resection and lymph node yield. Trends toward reduced estimated blood loss and shorter hospital stay in the robotic group did not reach statistical significance. : Robotic pancreaticoduodenectomy demonstrates comparable safety and oncological efficacy to the open approach, with longer operative times but potential perioperative advantages. These findings support the continued integration of robotic techniques even in medium-volume centers with appropriate expertise.

摘要

机器人手术已成为传统手术方法的一种有前景的替代方案,具有更高的精准度和更好的人体工程学特性。然而,由于技术复杂性和陡峭的学习曲线,其在胰十二指肠切除术(PD)中的应用仍存在争议。本研究旨在评估在单一高容量中心进行机器人辅助与开放胰十二指肠切除术的围手术期结果,使用治疗权重逆概率(IPTW)来控制混杂变量。:对2020年1月至2024年12月期间接受PD手术的患者进行了一项回顾性单中心分析。使用IPTW比较围手术期和肿瘤学结果,旨在平衡潜在的混杂变量。主要终点是术后90天死亡率;次要终点包括手术时间、估计失血量、术后主要并发症(Clavien-Dindo分级≥IIIa)和住院时间。:意向性分析纳入了74例患者(开放手术:n = 31;机器人手术:n = 43)。经过IPTW调整后,各组的基线特征达到平衡。机器人手术组的手术时间明显更长(中位数540分钟对479分钟,P = 0.009)。在90天死亡率(两组均为4.9%,P = 0.998)、术后≥IIIa级并发症或组织病理学结果(包括R0切除和淋巴结收获)方面未观察到显著差异。机器人手术组估计失血量减少和住院时间缩短的趋势未达到统计学意义。:机器人胰十二指肠切除术与开放手术相比,具有相当的安全性和肿瘤学疗效,手术时间更长,但具有潜在的围手术期优势。这些发现支持即使在具有适当专业知识的中等容量中心,也应继续整合机器人技术。
