Abstract

背景与目的电视辅助胸腔镜手术(video-assisted thoracoscopic surgery, VATS)是胸部微创手术的代表,相对于传统开胸手术(traditional open surgery, TOS),VATS具有创伤小、疼痛轻、恢复快等优势。本研究旨在比较VATS与传统开胸肺叶切除治疗非小细胞肺癌(non-small cell lung cancer, NSCLC)围手术期甲状腺激素水平的变化。方法选取卫生部北京医院胸外科2010年10月-2012年8月收治的NSCLC患者44例,根据手术方式的不同分为:胸腔镜组(VATS组,25例)及传统开胸组(TOS组,19例)。两组于手术前1天、术后第1天、2天、3天、7天分别测定游离T3(free T3, FT3)、游离T4(free T4, FT4)、反T3(reverse T3, rT3)、促甲状腺激素(thyroid stimulating hormone, TSH)的水平,观察两组术后各指标的变化规律,比较两组间变化的差异。结果术前患者甲状腺激素水平均在正常值范围内,两组比较无统计学差异(P>0.05)。FT3及TSH术后均表现为先降低后升高,分别于术后第3天、术后第1天达到最低水平,术后第7天时VATS组已恢复至术前水平,但TOS组FT3仍明显低于术前(P=0.032);FT4及rT3术后均表现为先升高后降低,均于术后第2天达到峰值,TOS组术后第1天、2天、3天rT3水平均明显高于VATS组(P < 0.05)。术后FT3降低及rT3升高均超出正常值范围,而FT4及TSH变化均在正常值范围内。两组间各指标变化趋势比较,rT3变化有统计学差异(F=7.557, P=0.009)。结论NSCLC患者行肺叶切除术后均出现正常甲状腺功能病态综合征,相对于传统开胸手术,胸腔镜手术对机体甲状腺激素水平影响小,机体应激反应小,利于肺癌患者术后恢复。
