Diagnostic Value and Safety of CT and US-Guided PTNB for Peripheral Pulmonary Lesions: A Meta-Analysis and Clinical Study

Abstract

Objective: To evaluate the diagnostic value and safety of CT and ultrasound-guided PTNB for peripheral type of occupying lung lesions by meta-analysis and clinical study. Methods: 1) The target data of randomized controlled trials of CT and ultrasound-guided PTNB for peripheral type of occupying lung lesions were extracted by computer search of foreign PubMed, Embase, the Cochrane Library, Web of Science databases, since the establishment of the database. Cochrane quality assessment criteria were used for evaluation. Statistical analysis was performed using Review Manager 5.3 software. 2) To retrospectively study the diagnosis rate and complication rate of patients, undergoing CT or ultrasound-guided PTNB in the First Affiliated Hospital of Dali University from January 2015 to December 2020. Results: Meta-analysis included 7 papers with a total of 1177 patients including 502 patients in the ultrasound group and 675 patients in the CT group. Meta-analysis results showed that there was no difference in the diagnosis rate of PTNB guided by ultrasound and CT. The incidence of postoperative complications was higher in the CT group than in the ultrasound group. The incidence of postoperative pneumothorax was higher in the CT group than in the ultrasound group, and there was no difference in the incidence of postoperative bleeding. 3) Clinical study results show that the puncture success rate was 100% in both of the ultrasound and CT groups, the pathological diagnosis rate was 85.48% in the ultrasound group and 91.67% in the CT group, and there was no difference in the overall complication rate between the two puncture groups. Conclusion: Either ultrasound or CT-guided PTNB is a safe and effective clinical diagnostic method for the diagnosis of peripheral pulmonary occupations.
