ABSTRACT
OBJECTIVE:
To evaluate the diagnostic utility of routine gastric biopsies taken at random versus targeted biopsies with methylene blue staining for the diagnosis of intestinal metaplasia. MATERIAL ANDMETHODS:
We performed a validation study in 376 patients. We performed 2 antral biopsies, 2 gastric body biopsies, 1 biopsy for urease test and additional biopsies if demanded. One hundred and one patients underwent 2 biopsies after methylene blue staining. A total of 1,486 biopsies were analyzed. Frequencies of histological and endoscopic diagnosis and the validation of endoscopic diagnosis of intestinal metaplasia with and without staining against histology, which followed updated Sydney and Vienna criteria, were determinedRESULTS:
Metaplasia was found in 37.23
