Abstract
BACKGROUND: Hepatobiliary stone disease is one of the most common surgical conditions worldwide. There are multiple causative agents responsible for the formation of hepatobiliary stones, and bacterial infection is one of them. The presence of Helicobacter DNA species has been investigated in the biliary epithelium of patients with biliary diseases. However, conflicting results have been observed that may have been due to the small number of subjects studied, difficulty in obtaining a healthy control group, absence of controlling for confounding factors, or ethical and regional differences among populations. METHODS: We investigated the presence of Helicobacter pylori species by PCR of 26-kDa surface antigen specific to H. pylori in bile samples from 50 cases with hepatobiliary stones and 25 controls without hepatobiliary stones. The control group comprised of 20 patients of hydatid cyst disease of liver and 5 patients of right colonic growth. RESULT: H. pylori was present in 20 bile samples among cases and was absent in 30 bile samples among cases. Among controls, H. pylori could not be detected. A significant association of the presence of H. pylori with hepatobiliary stone disease was seen (p < 0.001). CONCLUSION: There is an association between bile infection with H. pylori and hepatobiliary stone disease.
