Objective To compare the effects of thoracoscopic 2 hole and 3 hole for congenital pulmonary bulla resection.Methods 38 cases of congenital pulmonary bulla patients,both in the VATS downlink congenital pulmonary bulla resection.According to the number of holes,thoracoscopic operation were divided into the two groups. To observe the use of group 19 cases of 2 holes,19 cases 3 holes were adopted in the control group.Pull the chest tube operation time,operation time of the two groups were compared after.and the average hospitalization time after opera-tion,postoperative analgesia drug application.Results The observation group operation time,operation time,pulling the chest tube after operation the average hospitalization time, analgesic drug application rate respectively were (46.89 ±9.11)min,(3.95 ±0.85) d,(7.37 ±1.34) d,21.1%,The control group were (66.05 ±12.09) min, (4.37 ±0.98)d,(7.32 ±1.57)d,52.6%.There were statistically significant differences in rate of the two groups in operation time,analgesic drug application.(t=-5.516,χ2 =4.071,P<0.05);38 cases were cured,followed up for 3-24 months,no recurrence occurred in 1 cases.Conclusion Video assisted thoracic descending congenital pulmona-ry bulla resection,the 2 hole 3 hole more than minimally invasive,short operation time,postoperative analgesic use rate is low.
