[Adenocarcinoma of the gallbladder as a histopathological finding after cholecystectomy].

OBJECTIVE
We wanted to determine the incidence in our population of gallbladder adenocarcinoma based on a histopathologic study done after cholecystectomy in patients with a diagnosis of gallstones.


MATERIAL AND METHODS
We made a census-type study during the last 3 years that included a total of 4548 gallbladders. Histopathologic results were analyzed and recollected in an established format. Finally, we calculated the incidence of malignant neoplasias of gallbladder in our hospital.


RESULTS
The most common histopathologic finding was cholesterolosis (incidence: 26%), followed by xanthogranulomatous gallbladder (incidence: 0.94%). The incidence of gallbladder cancer was 0.54% (25 cases), the most common type being adenocarcinoma (incidence: 0.48%).


CONCLUSIONS
The incidence of gallbladder cancer in our hospital is among the lowest limits compared with the literature worldwide.
