Abstract:
Objective:To investigate the diagnosis and treatment value of intraoperative ultrasound (IOUS) in video-assisted thoracic surgery (VATS) of small solitary pulmonary nodule (SSPN).Methods:Of the 35 SSPN patients who received VATS in Tianjin Third Central Hospital from January 2016 to January 2020, the visual and touch examination (VTE) and IOUS method were used to locate pulmonary nodules during the operation. The differences between the two methods in the locating success rate and locating time were compared. The imaging findings of SSPN were classified and the sonographic characteristics of SSPN were summarized by univariate analysis.Results:The success rate of IOUS locating was 91.43%(32/35), which was higher than that of VTE 48.57%(17/35), and the difference was statistically significant (χ 2=15.310, P<0.001). The time of IOUS locating (6.23±1.93)min was shorter than that of VTE(9.98±1.56)min, and the difference was statistically significant ( t=6.940, P<0.001). The sonograms of 32 SSPN(17 malignancy and 15 benign) patients were all hypoechoic, univariate analysis showed that heterogeneous echo (χ 2=10.615, P=0.01) and unclear borderline (χ 2=10.041, P<0.001) were helpful to judge the benign or malignant. Conclusions:In video-assisted thoracic surgery, using IOUS could quickly and accurately locate and diagnose SSPN, which can shorten the operation time, improve the resection efficiency and guide the operation.
