[A long-term follow-up study with endoscope in chronic gastritis]

A 10 to 17 years endoscope follow-up was performed to 138 cases of chronic gastritis. The result showed that 118 cases still proved to be chronic gastritis, and the increase of chronic atrophic gastritis (CAG) in numbers. 15 cases developed into peptic ulcer. 5 cases to carcinoma (4 cases were early carcinoma). The time of cancerization differed from 2 to 12 years. The rate of cancerization of CAG reached 7.46%. The rate of cancerization of intestinal metaplasia (IM) were 8.20%. 13 cases of IM were mucus histo-chemical stained, and five of them contained sulfuric acid mucus, one of the 5 cases cancerized. 3 of 14 cases with atypical hyperplasia (ATP) turned into stomach cancer. We believe that chronic gastritis, especially CAG with ATP and IM, or with sulfuric acid mucus of IM had a high possibility of cancerization with the increase of age, and should be followed up for a long time.
