Objective To explore the diagnostic value of radial ultrasound(EBUS)combined with virtual navigation(VBN)in peripheral pulmonary nodules.Methods Two hundreds and forty cases of peripheral pulmonary nodules(0.8cm≤diameter≤3cm)in the respiratory department of our hospital from July 2014 to July 2015 were included and according to the different guide devices,which were divided into the radial ultrasound combined with virtual navigation group(EBUS+VBN group),radial ultrasound group(EBUS group),virtual navigation group(VBN group)and control group.The diagnostic rates were compared among the four groups and among different sizes of lesion.The time of lesion location and operating time were also compared between the EBUS+VBN group and EBUS group.Results Among 240 cases,the diagnostic rate in the EBUS+VBN group was highest(81.67%),and the diagnostic rates had statistically significant difference among the four groups(χ~2=19.34,P=0.00);the diagnostic rates of lesions less than 2cm in diameter were lower than that of lesions2cm in the EBUS+VBN group and EBUS group,but without statistically significant difference(χ~2=2.04,3.40,P=0.15,0.07);the locating lesions time and operating times in the EBUS+VBN group were shorter than those in the EBUS group,but the difference between them was not statistically significant(P=0.03,0.04).Conclusion EBUS combined with VBN could improve the diagnostic rate of peripheral pulmonary nodules and shorten the time of lesion location and operating time.
