Helicobacter pylori in Cholecystectomy Specimens-Morphological and Immunohistochemical Assessment

Helicobacter pylori infection is associated with the risk and phenotypes of cholelithiasis: A multi-center study and meta-analysis

BACKGROUND

Helicobacter pylori (H. pylori) is a prevalent pathogen associated with various diseases. Cholelithiasis is also a common condition. H. pylori infection has been identified in the biliary system, suggesting its potential involvement in biliary diseases. However, the specific role of H. pylori in the development of cholelithiasis remains inconclusive.

AIM

To investigate the potential association between H. pylori infection and the development of cholelithiasis.

METHODS

We performed a retrospective study in more than 70000 subjects in health examination center from 3 institutions in the middle, northern and eastern China, from October 2018 to December 2021, to explore the potential association between H. pylori and cholelithiasis through univariate and multivariate analysis. Meanwhile, the influence of H. pylori on biliary-related parameters was investigated. A comprehensive analysis of previous studies concerned about H. pylori and cholelithiasis was also executed.

RESULTS

In our multi-center study, H. pylori was positively associated with cholelithiasis [odds ratio (OR) = 1.103, 95% confidence interval (CI): 1.001-1.216, P = 0.049]. Furthermore, H. pylori patients had less total and direct bilirubin than uninfected patients, while the total cholesterol and low-density lipoprotein cholesterol were more in H. pylori-positive participants (P < 0.05). In the published articles, the cohort studies indicated H. pylori was a risk factor of cholelithiasis (hazard ratio =1.3280, 95%CI: 1.1810-1.4933, P < 0.0001). The pooled results of case-control and cross-sectional studies showed positive association between H. pylori and cholelithiasis in Asia (OR = 1.5993, 95%CI: 1.0353-2.4706, P = 0.034) but not in Europe (OR = 1.2770, 95%CI: 0.8446-1.9308, P = 0.246). Besides, H. pylori was related to a higher choledocholithiasis/cholecystolithiasis ratio (OR = 3.3215, 95%CI: 1.1034-9.9986, P = 0.033).

CONCLUSION

H. pylori is positively correlated with cholelithiasis, choledocholithiasis phenotype particularly, especially in Asia, which may be relevant to bilirubin/cholesterol metabolism. Cohort studies confirm an increased risk of cholelithiasis in H. pylori patients.

The link between Helicobacter pylori infection and gallbladder and biliary tract diseases: A review

Helicobacter pylori is a gram-negative pathogen commonly associated with peptic ulcer disease and gastric cancer. H. pylori infection has also been reported in cholelithiasis, cholecystitis, gallbladder polyps, and biliary tract cancers. However, the association between H. pylori and gallbladder and biliary tract pathologies remains unclear due to the paucity of literature. In response to the current literature gap, we aim to review and provide an updated summary of the association between H. pylori with gallbladder and biliary tract diseases and its impact on their clinical management. Relevant peer-reviewed studies were retrieved from Medline, PubMed, Embase, and Cochrane databases. We found that H. pylori infection was associated with cholelithiasis, chronic cholecystitis, biliary tract cancer, primary sclerosing cholangitis, and primary biliary cholangitis but not with gallbladder polyps. While causal links have been reported, prospective longitudinal studies are required to conclude the association between H. pylori and gallbladder pathologies. Clinicians should be aware of the implications that H. pylori infection has on the management of these diseases.

Diagnosis and Therapeutic Management in Postcholecistectomy Alithiasic Cholangitis

Introduction:The objective of the current retrospective study is to present the results of a personal research on the prevalence and treatment of alithiasic cholangitis in hospitalized patients. Material and methods:The research was based on the following criteria: case selection according to gender, age and diagnosis, anamnesis information, clinical, paraclinical, imagery and laboratory investigation methods, therapeutic approach. Results:Between 2016-2018, 109 cases had a discharge diagnosis of postcholecystectomy cholangitis following clinical and paraclinical examinations. In a large percentage, cholangitis was alithiasic, imagery assessments showing only a dilation of the intra- and/or extra-hepatic biliary ducts (81 cases, 91.01%). Conclusions:Alithiasic cholangitis has been the main biliary cause in the postcholecystectomy pathology in this reference study (91.01%). In hospitalized people with alithiasic cholangitis as main diagnosis, highlighted endoscopic retrograde cholangiopancreatography (ERCP) represented a modern therapeutic approach; this allows the improvement of sphincter Oddi functional disorders through sphincterotomy/sphincteroplasty (6.75%).

Relationship between Helicobacter pylori-positivity in the gallbladder and stomach and effect on gallbladder pathologies

Objective

Helicobacter pylori commonly occurs in the stomach, but localizations outside the stomach and related diseases have also been investigated. However, the relationship between H. pylori and gallstones remains controversial. We aimed to investigate the relationships between H. pylori in the stomach and the gallbladder and gallstones.

Methods

This prospective case-control study included patients who underwent cholecystectomy because of gallstones, pancreatic head cancer, or hepatic resection. The patients were separated into two groups according to the detection of H. pylori in gallbladder samples using Giemsa staining. Stomach H. pylori status was based on previous gastroscopy.

Results

The study enrolled 60 patients, comprising 27 patients with gallstones and 33 without. There was no significant difference in the incidence of gallstones between patients with or without H. pylori in the stomach or gallbladder. Furthermore, the presence of H. pylori in the stomach was measured in 14 patients and was significantly correlated with H. pylori in the gallbladder.

Conclusion

The current study showed no relationship between the occurrence of gallstones and the presence of H. pylori in either the gallbladder or the stomach. In contrast to previous reports, this suggests that H. pylori does not play a role in the development of gallstones.
