Introduction: Gallbladder cancer is a rare disease and represents the most common malignant neoplasia of the biliary tree and the seventh most frequent in the gastrointestinal tract. The incidental gallbladder carcinoma is found in about 1 to 2% of the cases.
Objective: The purpose of this study is to appraise the incidence of incidental gallbladder cancer in patients submitted to cholecystectomy due to acute cholecystitis.
Methods: The patients’ charts as well as the anatomopathological specimens were analyzed. 515 urgent cholecystectomies performed with diagnostic hypotheses of acute cholecystitis, between September 2015 and March 2019 at the Hospital, were appraised retrospectively.
Results: After analysis of the specimens, the authors identified 7 cases of incidental gallbladder carcinoma. The age of the patients who came up with incidental carcinoma was statistically higher than those without the malignant disease (p < 0.05). The incidence of this neoplasia increases with age, namely higher for patients over 60 years old (3.75%).
Conclusion: Considering this fact, in the emergency setting, the suspicion of incidental gallbladder cancer must always be considered, especially when a meticulous appraisal is not always possible, and the distinction between an inflammatory or a tumoral thickening is, therefore, very difficult to be done.
