MUNOZ Z, CLAUDIO et al. Frequency of gallbladder dysplasia in gallbladders excised during cholecystectomy. Rev Chil Cir [online]. 2008, vol.60, n.3, pp.198-201. ISSN 0718-4026. http://dx.doi.org/10.4067/S0718-40262008000300006.
Introduction: Gallbladder dysplasia is considered a premalignant stage, preceding the appearance of carcinoma. Aim: To assess the prevalence of gallbladder dysplasia in gallbladder biopsies. Material and methods: Review of pathology reports of 1237 gallbladders obtained during cholecystectomies, during 2003. Results: Thirty one reports informed the presence of dysplasia (2.5 %). Of these, 12 were in stage 1 (39 %), 14 were in stage 2 (45 %) and 5 in stage 3-ISC (in-situ carcinoma, 16 %). The mean age of patients with gallbladder dysplasia was 54 years. Discussion: Gallbladder dysplasia is common. The pathological study of the excised gallbladders is the only way to make the diagnosis
