ObjectiveTo observe the effect of thoracoscopic resection of esophageal carcinoma with preservation of pulmonary branches of vagus nerve on postoperative pulmonary infection. MethodsThe clinical data of 60 patients receiving thoracoscopic resection of esophageal carcinoma were retrospectively analyzed. According to the presence of preservation of pulmonary branches of vagus nerve, all patients were divided into a group with preservation of pulmonary branches of vagus nerve(observation group) and a group without preservation of pulmonary branches of vagus nerve (control group), with 30 cases in each group. Operation duration, anesthesia time, and incidence of postoperative pulmonary infection were observed in the two groups. ResultsThoracoscopic surgery were all accomplished in sixty patients. There was no statistically significant difference in operation duration or anesthesia time between the two groups (P＞0.05). The incidence rate of postoperative pulmonary infection in the observation group was 3.3% (1/30), which was significantly lower than 20.0%(6/30) in the control group (P＜0.05). ConclusionIn thoracoscopic resection of esophageal carcinoma, preservation of pulmonary branches of vagus nerve can reduce the incidence rate of postoperative pulmonary infection to a certain extent.
