探讨慢性胆囊炎肠上皮化生的发生率、类型及其与胆囊结石和不典型增生的关系。对 1339例慢性胆囊炎组织中肠上皮化生和不典型增生的发生率分别为 39 96 %和 0 97% ;慢性胆囊炎的肠上皮化生至少可以分为结肠型、小肠型和混合型三种 ;肠上皮化生尤其是结肠型与不典型增生有密切的关系 ;肠上皮化生和不典型增生与有无合并胆囊结石无关。慢性胆囊炎的肠上皮化生尤其是结肠型肠上皮化生可能与胆囊癌的发生有密切关系
To investigate the incidence and types of intestinal metaplasia in chronic cholecystitis and its relationship with gallstone and atypical hyperplasia. The incidence of intestinal metaplasia and dysplasia in 1339 cases of chronic cholecystitis were 39 96% and 97%, respectively. The incidence of intestinal metaplasia in chronic cholecystitis could be divided into at least colon, small intestine and mixed type three Species; intestinal metaplasia, especially colon and atypical hyperplasia are closely related; intestinal metaplasia and dysplasia with or without gallstone involvement. Intestinal metaplasia of chronic cholecystitis, especially colon-type intestinal metaplasia may be closely related to the occurrence of gallbladder cancer
