Abstract:
Objective To investigate the application of MSCT three-dimensional digital navigated biopsy in subcarinal lesions.Methods 82 patients were enrolled.Study subjects were randomly divided into control group and research group.Three-dimensional positioning and three-dimensional navigation needle biopsy were used in research groups, while CT cross-sectional image positioning with conventional puncture needle was used in control group.Puncture accuracy, one-time success rate of puncture, complications, diagnosis accuracy and operation time were compared between the two groups.Results Puncture success rate, definite diagnosis rate were 87.80%(36/41) and 97.56%(40/41) for the research group,and 60.97%(24/41) and 80.49% (33/41) for the control group, respectively,which on the research group were higher than that on the control group(χ2=8.945, 6.116;P<0.05).Complication rate and operating time were 14.63% (6/41) and (11.64±2.76) min for the research group, and 41.45% (17/41) and (22.22±6.31) min for the control group, respectively, which were lower on the research group than that on the control group (χ2=7.31,t=-11.70,P<0.05).Conclusion MSCT three-dimensional digital navigated biopsy technique could promote the efficiency of subcarinal space puncture biopsy significantly,which is a novel, convenient, precise and safe method.
