Abstract:
Objective To study the significances of various gastroscopic findings in chronic atrophic gastritis.Methods To contrastively analyse various findings of CAG under gastroscopic direct vision and their corresponding pathologic diagnosis in 55 cases, and to calculate respectively the sensitivity and specificity of CAG, intestinal metaplasia (IM), atypical hyperplasia (ATP) through various gastroscopic expressions.Results Of the 55 patients CAG 30 cases, CAG and CSG 25 cases were diagnosed by endoscopy; the pathological diagnoses were CAG 36, CSG 8 and CAG plus CSG 11 cases. The coincidence rate of diagnosis between endoscopy and pathology was 85 45%. The sensitivities of gastroscopic findings in CAG to their pathology were about 12 77%～51 06%. Some manifestations in gastroscopy such as piebald change and flat protrusion in CAG have high specificity to pathology about 87 50% and 75 00% respectively. The dominated white phase, prominent vascular pattern with flat protrusion and piebald with erosive protrusion attained the specificity of 100% to the pathology. The asperous and granular changes had higher diagnostic value about IM, its sensitivity and specificity was 66 67% and 71 74% respectively. The dominated white phase and prominent vascular pattern had higher sensitivity, 71 74% in diagnosing ATP. Erosive protrusion had higher specificity, 68 89% in diagnosing ATP.Conclusion Piebald change, asperous and granular changes, dominated white phase and prominent vascular pattern under gastroscopy are highly helpful to the pathological diagnosis of CAG, IM and ATP. But the combination of gastroscopic and pathologic examination is the inevitable procedure in correct diagnosis of CAG, IM, and ATP.
