Abstract:
Objective:To explore the application of transbronchial lung cryobiopsy guided by endobronchial ultrasound sheath (EBUS-GS-TBCB) in diagnosis of nonresolving pneumonias.Methods:Sixty patients with nonresolving pneumonias from March 2019 to July 2020 in Dalian Municipal Central Hospital were selected. The patients were divided into EBUS-GS-TBCB group (31 cases) and transbronchial forcep lung biopsy guided by endobronchial ultrasound sheath(EBUS-GS-TBLB) group (29 cases) by random digits table method.Results:The diagnostic rate of nonresolving pneumonias in EBUS-GS-TBCB group was significantly higher than that in EBUS-GS-TBLB group: 87.10% (27/31) vs. 65.52% (19/29), and there was statistical difference ( χ2 = 3.90, P = 0.048). There were no statistical difference in sensitivity, specificity, accuracy, positive predictive value and negative predictive value between 2 groups ( P>0.05). There were no statistical difference inthe shortest distance from lesions to pleura, incidence of pneumothorax and incidence of bleeding between EBUS-GS-TBCB group and EBUS-GS-TBLB group: (27.42 ± 2.88) mm vs. (27.01 ± 2.37) mm, 6.45%(2/31) vs. 3.45%(1/29) and 22.58%(7/31) vs. 13.79% (4/29), P>0.05. Among the causes of nonresolving pneumonias, infectious factors accounted for 21.67% (13/60), non infectious factors accounted for 66.67% (40/60), and uncertain causes accounted for 11.67% (7/60). Conclusions:The diagnostic rate of EBUS-GS-TBCB in nonresolving pneumonias is significantly higher than EBUS-GS-TBLB, and the complications such as bleeding and pneumothorax do not increase significantly.
