Abstract:
Objective To study the prevalence of intestinal metaplasia (IM) ,dysplasia and carcinoma at the distal esophagus and esophagogastric junctions as well as the relationship between SCJ and RE. Methods In 391 patients the main symptoms , RE and its degree by gastro endoscopy, and biopsy specimens from the mucosa just below SCJ were investigated. Results The prevalence of IM in LSBE,SSBE and GEJ is 26. 53% , 33.85% and 34.00% respectively; It increases with age after 40 years old and no difference occurs between' the male and female. ;12 cases of dysplasia were diagnosed ( low -grade 7 cases , medium and high-grade 5 cases) . Sixteen cases of cardia carcinomas and 1 case of esophageal adenocarcinoma were diagnosed; The longer the SCJ moved upward above GEJ, the higher the prevalence and severeness of RE . Conclusions 1. There is no difference about the prevalence of IM among LSBE,SSBE and GEJ; 2. It is important to pay attention to the diagnosis of dysplasia in the distal esophagus and esophagogastric junctions; 3. The prevalence of cardia carcinomas is much higher than that of esophageal adenocarcinoma.
