Application of Virtual Navigation Bronchoscopy Combined with EBUS-GS Technology in the Diagnosis of Peripheral Pulmonary Nodules with a Diameter of≤2 cm
Objective:To explore the diagnostic value of virtual navigation bronchoscopy combined with EBUS-GS technology in the diagnosis of peripheral pulmonary nodules with a diameter of ≤ 2 cm.Method:This study used a retrospective analysis method and selected 140 patients with peripheral pulmonary nodules with a diameter of ≤ 2 cm who visited our hospital from May 2019 to May 2022 as the study subjects.They were randomly divided into a control group and an experimental group,with 70 patients in each group.The control group was diagnosed using traditional bronchoscopy technology,while the experimental group was diagnosed using virtual navigation bronchoscopy combined with EBUS-GS technology,and follow-up experiments were conducted.Record and compare indicators such as visual acuity,surgical time,diagnostic rate,and incidence of complications between the two groups of patients.Result:There was no statistically significant difference in the location of lesions between the control group and the experimental group(P＞0.05).There was no statistically significant difference in lesion size between the experimental group and the control group(P＞0.05),and the visual acuity of the experimental group was higher than that of the control group.There was no significant statistical difference(P＞0.05)in the total time of bronchoscopy between the control group and the experimental group.Compared with the control group,the experimental group had a lower time to detect the location of the lesion(P＜0.05).The diagnostic rate of malignant lesions in the experimental group was 89.74％,and the diagnostic rate of benign pulmonary nodules was 83.87％.However,the diagnostic rate of malignant lesions in the control group was 60％,and the diagnostic rate of benign nodules was 50％.The difference in the diagnostic rates of benign and malignant lesions between the two groups was statistically significant(P＜0.05).Compared with the control group,the incidence of adverse reactions in the experimental group was 2.86％lower than that in the control group,which was 18.57％,with a statistically significant difference(P＜0.05).Conclusion:Virtual navigation bronchoscopy combined with EBUS-GS technology is a feasible and effective method for the diagnosis of peripheral pulmonary nodules with a diameter of ≤ 2 cm.This technology can improve diagnostic accuracy and reduce unnecessary resection surgeries,which has important clinical significance for patients.
