【摘要】 背景 肌少症是一种骨骼肌质量和总量进行性和全面性丧失的综合征,可以增加结直肠癌术后并发症
的风险,但对于手术部位感染的影响目前尚未定论。目的 评估基于腹部计算机断层扫描(CT)诊断的肌少症对结直
肠癌手术患者手术部位感染的影响。方法 回顾性收集 2019 年 7 月至 2021 年 12 月在南华大学附属第一医院胃肠外
科接受根治性结直肠癌切除术 328 例患者的临床资料,通过医院电子病历查询系统收集患者的信息。根据腹部 CT 结
果计算的第三腰椎骨骼肌肌肉质量指数,将患者分为肌少症组(n=44)和非肌少症组(n=284),参照《医院感染诊
断标准》评估患者手术部位感染发生情况。采用多因素 Logistic 回归分析探讨结直肠癌患者术后发生手术部位感染的
影响因素。结果 肌少症组手术部位感染发生率〔12(27.3%)〕高于非肌少症组〔35(12.3%)〕(P<0.05)。多因
素 Logistic 回归分析结果显示,肌少症〔OR=2.659,95%CI(1.221,5.791),P=0.014〕、美国麻醉师协会(ASA)分
级≥ 3 级〔OR=2.192,95%CI(1.140,4.216),P=0.019〕、肠造口〔OR=2.222,95%CI(1.160,4.257),P=0.016〕
是结直肠癌术后发生手术部位感染的危险因素。结论 合并肌少症是结直肠癌术后发生手术部位感染的危险因素,在
手术前筛查结直肠癌患者是否存在肌少症,并采取相关措施与功能锻炼,有利于改善患者预后。

【Abstract】 Background Sarcopenia,a syndrome of progressive and generalised loss of skeletal muscle,which can
increase the risk of postoperative complications of colorectal cancer,but its association with postoperative surgical site infections
in colorectal cancer is still inconclusive. Objective To evaluate the association of abdominal CT-assessed sarcopenia with
postoperative surgical site infections in patients undergoing colorectal cancer surgery. Methods Three hundred and twenty-eight
colorectal cancer patients underwent radical surgery in Gastrointestinal Surgery,the First Affiliated Hospital of University of South
China between July 2019 and December 2021 were selected. Clinical data were retrospectively collected through the electronic
medical record system. Sarcopenia was diagnosed by the L3 skeletal muscle index(L3 SMI) assessed using abdominal CT.
Surgical site infection was assessed using the Diagnostic Criteria of Nosocomial Infection(Trial). Multivariate Logistic regression
was applied to explore the influencing factors of postoperative surgical site infection. Results The incidence of surgical site
infection in sarcopenia group was higher than that in non-sarcopenia group〔27.3%(12/44) vs 12.3%(35/284)〕(P<0.05).
Multivariate Logistic regression analysis showed that sarcopenia〔OR=2.659,95%CI(1.221,5.791),P=0.014〕,ASA
