Abstract/OtherAbstract:
BACKGROUND AND AIM: Gallstones are known to produce diverse histopathological changes in the gall bladder. Our aim was to correlate various gallstone characteristics (number, size, weight, volume and morphological type) with the type of mucosal response in gall bladder (inflammation, hyperplasia, metaplasia and carcinoma).
METHODS: The study was conducted on 330 open cholecystectomy specimens with complete gallstones. The stones were assessed for various parameters i.e. number, size, weight, volume and morphological type. For microscopy, sections were obtained from the fundus, body and neck of the gallbladder. Additional sections were taken from abnormal looking areas.
RESULTS: Out of the 330 cases, 194 (59%) had mixed stones, 84 (25%) combined, 30 (9%) pigment and 22 (7%) had cholesterol stones. Number of stones varied from a single calculus in 131 (39.6%) cases, double in 29 (8.8%) and multiple in the remaining 170 (51.6%) cases. Cholecystitis, hyperplasia, metaplasia and carcinoma were more commonly seen with mixed and multiple stones. The average weight of calculi in cholecystitis was 2.551 gm, in hyperplasia 3.619 gm, metaplasia4.549 gm and 17.96 gm in cases with carcinoma. Similarly, average volume of the stone(s) was 2.664 ml in cholecystitis, 3.742 ml in hyperplasia, 4.532 ml in metaplasia and 19.178 ml in carcinoma. The average calculus size (2.147 cm) was found to be maximum in cases with carcinoma, followed by hyperplasia (1.187 cm), metaplasia (1.145 cm) and cholecystitis (1.136 cm).
CONCLUSION: As the weight, volume and size of the stone increases the changes in the gall bladder mucosa changes from cholecystitis, hyperplasia, metaplasia, dysplasia, to carcinoma.
