Abstract

Background: Carcinoma of the gallbladder is diagnosed in 0.3–1.5% of all cholecystectomy specimens.


Objectives: To establish the overall rate of gallbladder carcinoma and unexpected gallbladder carcinoma based on our experience.


Methods: We retrospectively evaluated all consecutive cholecystectomies performed in our ward during a 6 year period in order to determine the incidence of gallbladder carcinoma and to identify common characteristics of this particular group of patients.


Results: Of the 1,697 cholecystectomies performed in our ward during the 6 years, gallbladder carcinoma was diagnosed in six patients (0.35%), but was not suspected prior to surgery in any of them. In accordance with the literature, the occurrence in women (5/6) was higher than in men (1/6). The mean age was 70 years (range 55–90). The most common symptom was abdominal pain; the majority (5/6) had cholelithiasis, and the pathologic report confirmed the diagnosis of adenocarcinoma in all six patients.


Conclusions: The overall incidence of unsuspected gallbladder carcinoma in our series was 0.35%. We could not find any common characteristics for this particular group of patients when compared to patients with non-malignant pathology.
