Diagnostic Value of Guided Sheath Radial Probe Endobronchial Ultrasound-guided Transbronchial Lung Biopsy on Peripheral Pulmonary Lesions
Objective:To explore and analyze the positive rate of guided sheath radial probe endobronchial ultrasound-guided transbronchial lung biopsy(RP-EBUS-GS-TBLB)in the diagnosis of peripheral pulmonary lesions(PPL).Method:The case data of 100 patients with PPL confirmed by chest CT examination admitted to Jiangxi Provincial People's Hospital from March 2022 to February 2023 were retrospectively analyzed.All patients underwent RP-EBUS-GS-TBLB and radial probe endobronchial ultrasound-guided transbronchial lung biopsy(RP-EBUS-TBLB).The positive rate of PPL was compared between the two examination methods.Result:The total positive rate of RP-EBUS-GS-TBLB(71.00%)or the combination of the two examinations(81.00%)in diagnosing PPL was higher than that of RP-EBUS-TBLB(45.00%),the differences were statistically significant(P<0.05).There was no statistical difference in the total positive rate between RP-EBUS-GS-TBLB and the combination of two examinations in the diagnosis of PPL(P>0.05).There were statistical differences in the diagnostic positive rates of PPL between RP-EBUS-GS-TBLB and RP-EBUS-TBLB the in different probe positions and diameters in the diagnosis(P<0.05),the diagnostic positive rate of PPL of RP-EBUS-GS-TBLB in patients with lesion diameter≤20 mm and probe position near the lesion were significantly higher than those of RP-EBUS-TBLB,the differences were statistically significant(P<0.05).Conclusion:Compared with RP-EBUS-TBLB,RP-EBUS-GS-TBLB has a higher positive rate in the diagnosis of PPL.Repeated biopsy after the application of sheath canal can not enhance the diagnostic positive rate.There is a significant difference in the diagnostic positive rate of PPL among different probe positions and lesion sizes.For lesions larger than 20 mm,the application of guided sheath does not improve the positive rate of PPL,and can appropriately enhance the diagnostic positive rate of PPL for lesions near the probe position.
