Association of Clinicopathological features of Cholecystitis with Helicobacter Pylori Infection in Gall bladders
Background: Helicobacter pylori (H. pylori) have been associated with gastritis, but its presence in other parts of the gastrointestinal system has not been studied much. Few previous studies have identified “H. pylori” in gallbladder and found its association in causing cholecystitis and gallstones, but there is limited data showing a significant association in Pakistan. This study was designed to identify H. pylori microorganism in cholecystitis patients and find its association with the morphological changes seen in the affected gall bladders.
Material and Methods: All patients with acute and chronic cholecystitis admitted in Akbar Niazi Teaching Hospital (ANTH) between the ages of 18 and 80 years from January 2017 till March 2019, who underwent cholecystectomy, were included in the study. Gall bladder specimens were sent to Pathology department, ANTH after surgery and were analyzed for the presence of H pylori bacteria using Hematoxylin and Eosin and Giemsa staining. Signs of inflammation, hyperplasia, metaplasia, mucosal atrophy or erosion, lymphoid infiltration, fibrosis, cholesterolosis or any other morphological changes were also noted. Association of H. pylori with cholecystitis and other morphological changes were assessed by Chi Square analysis. P value less than 0.05 was considered statistically significant.
Results: Chronic cholecystitis was present in 91% cases and acute cholecystitis in 9%. Other histological findings were Hyperplasia (10%), Metaplasia (15%), Fibrosis (79%), Cholesterolosis (19%) and ulcerations (36%). H pylori was found in 17% of gall bladders and all the cases were of chronic cholecystitis, with 11.7% males and 88% females. Gallstones were present in 76.4% cases and were more common in 41-60 years’ age group (64.7%). Other histological findings seen in H. pylori positive cases were; Hyperplasia in 11.7% cases, Metaplasia in 17.6%, Fibrosis in 94.1%, cholesterolosis in 23.5% and ulcerations in 17.6% cases. Association of H. pylori with gender, cholecystitis, gall stones, histological features and age distribution was non-significant.
Conclusion: Although H. pylori infection has been found in cases of chronic cholecystitis and gall stone formation, its association with cholecystitis and other morphological changes could not be proved. Hence, it is uncertain whether H. pylori eradication in patients with gastritis can prevent cholecystitis or gall stones formation.
