Bile does not normally enter the stomach after gallstone surgery, but there may be a risk of inducing bile reflux. Gallstone surgery usually removes the gallbladder, which is an organ used to store bile. Without the gallbladder, bile will be discharged directly into the digestive tract after it has been produced, and the opening of the common bile duct lies in the large papilla of the duodenum, which is below the stomach, so bile is discharged directly into the duodenum, and does not enter the stomach without any special circumstances. However, after a major gastrectomy, gastrojejunostomy, pyloric dysfunction, or gallbladder removal, bile may flow back into the stomach and erode the stomach, resulting in bile reflux gastritis. This situation needs to go to the hospital according to the doctor’s instructions for treatment, such as the use of gastric stimulant Mosapride, gastric mucosal protective agent aluminum thioglycollate, acid inhibitor Famotidine and so on for treatment.
