Endoscopic technique
BILE REFLUX
An end-view gastroduodenoscope was used in all cases. The endoscope was introduced through the esophagus to the stomach where the endoscopist assessed the amount of bile reflux in the stomach. A scale of 0 to 2 was used where 0 means no bile, 1 means a minimal amount of bile staining the gastric mucosa, and 2 means a large amount of bile needed to be sucked [
