Objective:
Bile reflux gastritis is caused by the backward flow of duodenal fluid into the stomach. A retrospective cohort study was performed to estimate the prevalence and risk factors of bile reflux gastritis postcholecystectomy, and to evaluate the endoscopic and histopathologic changes in gastric mucosa.
Methods:
Patients with refractory upper abdominal pain right below the ribs with symptoms of bloating, burping, nausea, vomiting, and bile regurgitation during the period from January 2018 to December 2020, submitted to Zagazig University Hospitals were enrolled in this study. The studied 64 patients were divided into two groups; the control group (CG): 30 subjects who had never undergone any biliary interventions, and the post-cholecystectomy group (PCG): 34 patients who had undergone cholecystectomy.
Results:
The prevalence of bile reflux gastritis was (16.7%) and (61.8%) in CG and PCG, respectively. Diabetes, obesity, elevated gastric bilirubin, and elevated stomach pH were all risk factors for bile reflux gastritis in both groups (r = .28,.48,.78,.57 respectively). Age, sex, epigastric pain, heartburn, vomiting, and the existence of bile reflux gastritis, on the other hand, had no correlation.
Discussion:
After a cholecystectomy, bile reflux gastritis is prevalent, especially among obese and diabetic patients.

01:17Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
