| 摘 要： | 目的研究术前CT指标与全胸腔镜（VATS）肺叶切除手术中转开胸之间的关系。方法选取2016年12月~2019年12月我院871例肺部占位性病变患者为样本进行前瞻性研究,均完成CT检查并进行VATS肺叶切除术,其中中转开胸手术者为28例（3.21%）,作为中转组; 采用随机数字表法从顺利完成VATS手术的患者中抽取100例作为VATS组,比较两组一般资料、CT检查结果及手术结果,分析术前CT检查对VATS中转开胸的影响和预测价值。结果VATS组手术时间、术中出血量、引流时间及住院时间均低于中转组,差异有统计学意义（P < 0.05）; 两组术后感染、气胸及肺不张等并发症差异无统计学意义（P>0.05）; VATS组CT征象中最大淋巴结短径以及肿瘤浸润和胸膜凹陷征发生率均低于中转组（P < 0.05）,两组肺野病灶位置、病灶最大径和淋巴结钙化比较差异无统计学意义（P>0.05）; Logistics回归分析显示肿瘤浸润是影响VATS中转开胸的独立危险因素（P < 0.05）; ROC曲线分析示肿瘤浸润、最大淋巴结短径、胸膜凹陷征以及3项CT指标联合预测VATS中转开胸的灵敏度分别为82.14%、67.86%、67.86%和78.57%,特异度分别为89.00%、69.00%、93.00%和93.00%。结论VATS中转开胸可对患者术后康复造成不良影响,其主要原因为肿瘤浸润或淋巴结粘连导致血管等解剖结构分离难度增加,肿瘤浸润、最大淋巴结短径和胸膜凹陷征等术前CT指标对评估中转开胸风险具有一定参考价值。

| Abstract: | ObjectiveTo explore the relationship between the preoperative CT indexes and conversion to thoracotomy during video assisted thoracoscopic surgery (VATS) lobectomy.MethodsA total of 871 patients with lung space-occupying lesions in our hospital from December 2016 to December 2019 were selected. The patients completed the CT examination and underwent VATS lobectomy. Among them, 28 cases were converted to thoracotomy, accounting for 3.21%. 100 cases from patients who successfully completed VATS surgery were extracted as VATS group by the random number table method. The general data, CT examination results and surgical results were compared between the two groups. The influence and predictive value of preoperative CT examination on conversion of VATS to thoracotomy were analyzed.ResultsThe surgical time, intraoperative blood loss, drainage time and hospitalization timem in VATS group were significantly lower than those in conversion group(P < 0.05). There were no significant differences in the complications such as postoperative infection, pneumothorax and atelectasis between the two groups (P>0.05). The CT signs of short diameter of the largest lymph node and incidence rates of tumor infiltration and pleural indentation in VATS group were significantly lower than those in conversion group (P < 0.05). There were no significant differences in the location of lung field lesions, the largest diameter of lesions and lymph node calcification between the two groups (P>0.05). Logistics regression analysis showed that tumor infiltration was an independent risk factor affecting the conversion to thoracotomy in VATS (P < 0.05). ROC curve analysis showed that the sensitivities of tumor infiltration, short diameter of the largest lymph node, pleural indentation and the combination of the three CT indexes in predicting VATS conversion to thoracotomy were 82.14%, 67.86%, 67.86% and 78.57%, and the specificities were 89.00%, 69.00%, 93.00% and 93.00% respectively.ConclusionVATS conversion to thoracotomy can adversely affect postoperative rehabilitation of patients. The main reasons are that tumor infiltration or lymph node adhesion leads to increase difficulty in separating blood vessels and other anatomical structures, and preoperative CT indexes such as tumor infiltration, short diameter of the largest lymph node and pleural indentation have a certain reference value in assessing the risk of conversion to thoracotomy. |
