Gastric Intestinal Metaplasia
Conditions
Brief summary
Investigators found that the degree and the duration of aceto-whitening differed between gastric intestinal metaplasia(GIM) and the surrounding normal mucosa: the area of GIM showed a severe degree of aceto whiteness and the whitening continued longer than the surrounding normal mucosa, which investigators called severe whitening and delayed fading, and investigators realized that GIM could possibly be diagnosed by using these differences.The aim of this prospective study was to investigate the efficacy of severe whitening and delayed fading for diagnosing GIM.
Interventions
Acetic acid-enhanced endoscopy combines conventional endoscopy with the instillation of acetic acid.
The concentration of acetic acid used in this study is 1.5%.
This study using an EG-29-i10 endoscope (Pentax, Tokyo, Japan) and an EPK-i7010 processor (Pentax, Tokyo, Japan).
