Bile Reflux Gastropathy: Prevalence and Risk Factors After Therapeutic Biliary Interventions

Gastric mucosa alterations as erythema, bile existence in the stomach, gastric folds thickening, erosions, and petechiae were also recorded (Olympus single-channel CLK-4). Multiple biopsies were taken from gastric mucosa for histopathological study. Via Triple Lumen ERCP Cannula, 5 mL of gastric fluid was aspirated through the suction channel of the endoscope and collected in a sterile trap placed in the suction line, to be sent for analysis. Quantitative determination of gastric aspirate total bilirubin level was performed (Gen.3® kit and Cobas 8000 analyzer). The pH monitoring of gastric aspirate was performed during the gastroscopy just after collection with a glass electrode pH meter (Adwa®).
