The value of different methods in diagnosis of intestinal tuberculosis

Abstract

Objective To investigate the value of different methods in diagnosis of intestinal tuberculosis.Methods A total of 34 endoscopic biopsy specimens from patients with of intestinal tubertulosis were subjected to abdominal X-rays、colonoscopy、pathoassay.Results The positive rate of intestinal tuberculosis by pathological histology colonoscopy、TB-PCR、abdominal X-rays、PPD test were 82.6%,52.2%,73.9%,47.8%and 52.2%respectively.The false-positive rates were 9.1%、27.3%、18.2%、27.3%and 9.1%;34 cases among the pathological diagnosis in 19 cases(82.6%)were significantly higher than the endoscopic diagnosis in 12 cases(52.2%)(X~2=4.98,P<0.05).Conclusions The positive rate of diagnosis of intestinal tuberculosis was not high,histopathological and PCR detection can significantly improve the diagnostic rate in patients with intestinal tuberculosis.
