Abstract:
Introduction: Cholecystectomy performed for benign diseases of the gallbladder is important for the diagnosis of gallbladder cancer. This is done by pathological examination of the removed specimens for patients with no detected or suspected complications before surgery. Although some centers undertake selective approaches for histopathological examination of gallbladder specimens, many centers perform this examination routinely. In our study, we investigated results of pathological examinations carried out on cholecystectomy specimens, in respect to unexpected cases of gallbladder cancer.
Methods: We reviewed cholecystectomy cases performed for benign diseases of gallbladder from January 2012 to February 2016 by investigating pathological specimens from the gallbladder. We evaluated demographical properties and their association with the pathological diagnosis and frequency of unexpected gallbladder cancer cases. We reported additional treatment and survival information of the malignancy cases after surgery.
Results: We reviewed 1294 cases of cholecystectomy, and the mean patient age was 47.5 +/- 14.3 years. The most frequent diagnosis was chronic cholecystitis (92.3%), and it was more prevalent among younger patients and female sex (P < 0.0001). Five patients (0.4%) were determined to have gallbladder cancer, and the mean age of these cases was 65.6 +/- 18.2 years. Two cases were Stage 2, two cases were Stage 3(B), and one case was Stage 3(A). There was no T-1 or T-is is tumor.
Conclusion: Routine histopathological examination of gallbladder is significant with respect to the determination of additional interventions at the postoperative period required for cancer cases coincidentally diagnosed.
