目的：讨论术前控制营养状态（CONUT）评分对行达芬奇机器人辅助食管癌 Mckeown 术（RAME）后患者并发症的预 测价值。方法：回顾性分析 2019 年 3 月—2024 年 3 月于兰州大学第一医院行 RAME 的 203 例患者，依据 COUNT 评分将患 者分为高 CONUT 组（≥ 3 分，n=34）与低 CONUT 组（<3 分，n=169），对比两组患者的临床特征与术后并发症差异，采 用 Logistic 回归分析探讨影响患者术后并发症的因素。结果：高 CONUT 组患者术后总体并发症的发生率、吻合口狭窄、吻 合口瘘、胸腔积液、切口感染的发生率显著高于低 CONUT 组（P<0.05）。术前胆固醇计数、COUNT 评分为影响术后并发症 的可能危险因素，COUNT 评分≥ 3 分为预测 RAME 术后患者并发症的独立危险因素（P<0.05）。结论：COUNT 评分可作为 RAME 术后患者并发症发生的一个强有力的独立预测指标，有助于为患者提供精确且及时的个体化治疗和干预以改善预后。

Objective: To investigate the predictive value of the preoperative Controlling Nutritional Status (CONUT) score for postoperative complications in patients undergoing robot-assisted McKeown esophagectomy (RAME). Methods: A retrospective analysis was performed on 203 patients who underwent RAME at the First Hospital of Lanzhou University from March 2019 to March 2024. Patients were divided into the high-CONUT group ( ≥ 3 points, n=34) and the low-CONUT group (<3 points, n=169) based on preoperative CONUT scores. Clinical characteristics and postoperative complications were compared between the groups of patients. Logistic regression analysis was used to identify risk factors for complications. Results: The high-CONUT group showed significantly higher incidence of overall postoperative complications, anastomotic stricture, anastomotic leakage, pleural effusion, and surgical site infection compared to the lowCONUT group (P<0.05). Preoperative cholesterol levels and CONUT score were identified as potential risk factors for complications, with a CONUT score ≥3 points serving as an independent predictor of postoperative complications for RAME (P<0.05). Conclusion: The CONUT score is a robust independent predictor of complications following RAME, enabling precise and timely individualized interventions to improve patient prognosis.
