This study aimed to correlate the diagnostic efficiency of brushing cytology versus endoscopic biopsies in the diagnosis of various gastro-intestinal lesions with especial reference to gastric tumours.
Eighty three patients who had visible mucosal lesions were studied. All lesions were brushed and biopsied and were read blindly by one pathologist .
The sensetivety and positive predictive values for brushing cytology were 91.3% and 84.6% respectively, while specificity and negative predictive value were 93.3% and 96.5% respectively. The cumulative diagnostic yield for both test was 92.7%.
We concluded that brush cytology is a convenient, safe & accurate technique for the diagnosis of various gastro intestinal lesions which should be used concurrently with endoscopic biopsies
