RESUMO
Purpose To investigate the histopathological diagnosis and follow-up of gastric mucosal biopsy. Methods A detailed histopathological observation was performed on 5 748 gastroscopic biopsies and 3 288 patients were followed up. Results In 5 748 cases of endoscopy biopsy specimens, acute gastritis was rechecked in 125 cases, of which 112 cases were cured or improved (89.6％ ), 10 cases (8.0％ ) had little change, and 3 cases (2.4％) were aggravated. There were 2430 cases of chronic atrophic gastritis, in which 1521 cases were cured/improvement (62.6％ ), 737 cases (30.3％ ) had little change, and 172 cases (7.1％ ) were aggravated. In the 71 cases of special type of gastritis, 23 cases were cured or improved, accounting for 32.3％.42 cases were not changed much, accounting for 59.2％, and 6 cases were aggravated (8.5％ ). About druginduced gastritis/stomach reexamination in 94 cases, 57 cases were cured/improved, accounting for 60.6％, 34(36.3％ ) cases did not change, and 2 cases were aggravated(3.2％ ).183 cases of gastric polyp were reviewed, 165 cases(90.2％ ) were cured / improved, 13 cases (7.1％ ) were not changed and 5 cases (2.7％ ) were aggravated. No neoplasia/ nondysplasia was found in 205 cases, 196(95.6％ ) cases was cured / improved, no change was seen in 6 cases (2.9％ ) and aggravation was seen in 3 cases(1.5％). Indefinite neoplasia/ dysplasia was reexamined in 24 cases, 2 cases (8.3％) were cured/improved, no change was seen in 13 cases (54.2％ ), and aggravation was seen in 9 cases(37.5％).156 cases of intraepithelial neoplasia were retrospectively reviewed, in which138 (88.5％ ) cases were cured or improved, 4(2.6％ ) cases showed no change, and 13(8.3％) cases were aggravated. Conclusion It is of great significance to improve the early diagnosis rate, reduce missed diagnosis rate and misdiagnosis rate of gastric cancer by establishing 11 pathological changes and accompanying lesions.
