Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Bile reflux gastropathy is caused by the backward flow of duodenal fluid into the stomach. A retrospective cohort study was performed to declare if the therapeutic biliary interventions cause bile reflux gastropathy, and to estimate its prevalence and risk factors, and to evaluate the gastric mucosa endoscopic and histopathologic changes.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Bile reflux gastropathy is a pathological condition in the form of the backward flow of duodenal fluid that consists of bile, pancreatic juices, and secretions of the intestinal mucosa into the stomach and esophagus, causing mucosal lesions. Bile acids, in combination with gastric acid, have been shown to cause bile reflux gastropathy symptoms (heartburn, regurgitation, epigastric pain, etc.).

Bile reflux gastropathy frequently occurs after gastric surgeries that that damages the pyloric sphincter, and after biliary surgeries and procedures as cholecystectomy, endoscopic sphincterotomy (EST), endoscopic stenting, or choledochoduodenostomy that cause the sphincter of Oddi malfunction.\[4\] Bile gastropathy is a normal physiological event in a prolonged fasting period (primary bile reflux gastropathy).In non-responsive individuals to PPI medication, the total prevalence of biliary reflux was 68.7%. These people have acid and bile reflux at the same time and have never had biliary surgery.

Endoscopic retrograde cholangiopancreatography (ERCP) became an increasingly popular modality for both the diagnosis and the treatment of biliary tract disorders. It represents one of the most demanding and technically challenging procedures in gastrointestinal endoscopy, which must be performed effectively and safely by operators with substantial training and experience to maximize success and safety. Cholecystectomy is a surgical operation of gallbladder removal. It can be performed either laparoscopically, using a video camera, or via an open surgical technique. Pain and complications caused by gallstones are the most common reasons for cholecystectomy.

Postcholecystectomy group

which included patients that had undergone cholecystectomy.

upper GIT endescopy

Intervention Type DEVICE

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®).

Biliary intervention group

included patients who had undergone at least one of the following procedures for treatment of benign pathology: endoscopic sphincterotomy (ES) and endoscopic stenting.
