Shear wave elastography guided biopsy in diagnosis of tuberculous peritonitis / 中国介入影像与治疗学

ABSTRACT

Objective To assess the clinical value of ultrasound shear wave elastography (SWE) guided biopsy for diagnosis of tuberculous peritonitis.Methods Clinical data of 25 tuberculous peritonitis patients who underwent SWE guided biopsy (SWE guided group) and other 25 tuberculous peritonitis patients who underwent conventional ultrasound guided biopsy (conventional ultrasound guided group) were retrospectively analyzed.The successful rate of biopsy and the complication occurrence were compared between the two groups.Results The success rate of SWE guided group was 100％(25/25),and the rate of complication occurrence was 8.00％ (2/25).The successful rate and complication occurrence in conventional ultrasound guided group was 84.00％ (21/25) and 32.00％ (8/25),respectively.There were statistical differences of success rate of biopsy (x2=4.348,P=0.037) and the complication occurrence (x2=4.500,P=0.034) between the two groups.Conclusion Compared with conventional ultrasound,SWE guidance can improve the success rate and reduce the complication occurrence of biopsy.
