目的探讨微创手术与传统开胸手术对食管癌患者术后肺部感染及肺功能的影响。方法选取2015年6月—2016年12月收治的80例食管癌患者作为研究对象,随机分为观察组与对照组各40例。对照组采用传统开胸手术,观察组采用胸腔镜食管癌根治术,比较两组肺部感染发生情况以及用力肺活量(Forced vital capacity,FVC)、每分钟最大通气量(Maximum minute ventilation,MVV)、1 s用力呼气容积(Forced expiratory volume in one second,FEV1)。计量资料比较采用t检验,计数资料比较采用χ~2检验,P<0.05为差异有统计学意义。结果观察组术后肺部感染率低于对照组,差异有统计学意义(P<0.05);术后两组肺功能指标均降低,但与对照组相比,观察组FVC、FEV1、MVV指标降低幅度较小,差异有统计学意义(均P<0.05)。结论食管癌患者采用微创手术治疗效果确切,术中对患者的创伤小,有利于降低术后肺部感染,改善肺功能。
Objective To investigate the effect of minimally invasive surgery and conventional open thoracotomy on postoperative pulmonary infection and pulmonary function in patients with esophageal cancer. Methods Eighty esophageal cancer patients enrolled from June 2015 to December 2016 were randomly divided into observation group and control group with 40 cases each. The patients in the control group underwent conventional thoracotomy. In the observation group, thoracoscopic esophageal cancer was used for radical surgery. The incidence of pulmonary infection, Forced vital capacity (FVC), and Maximum minute ventilation (MVV) were compared between the two groups. 1 s forced expiratory volume in one second (FEV1). Comparison of measurement data using t test, count data were compared using χ ~ 2 test, P <0.05 for the difference was statistically significant. Results The postoperative pulmonary infection rate in the observation group was lower than that in the control group (P<0.05). The lung function was decreased in both groups, but compared with the control group, the FVC, FEV1, and MVV indexes in the observation group. The decrease was smaller and the difference was statistically significant (all P<0.05). Conclusions The minimally invasive surgical treatment of esophageal cancer is effective. The trauma to the patient during the operation is small, which is beneficial to reduce postoperative pulmonary infection and improve lung function.
