Three kinds of chronic cholecystifis were investigated with SEM.The results showed thatin the mild chronic cholecystitis,pathological changes represented mainly the collapse on the surfaceof the mucosa and the separation of the columnar cells;while in the moderate ones,erosivechanges on the surface of the epithelium were revealed and in the severe chronic cholecystitis,patchy desquamation of the columnar cells occurred as a result,the lamina propria and thefibro-connective tissue under lamina propria were exposed.In all the three types of the cholecysfitis,mucoid droplets and cholesterol crystals could be seen on the surface of the epithelium.Differentnumbers of lymphocytes were found in the lamina propria.
