BBCMADE Nomogram Validation for High-Risk Gastric Content in Sedative Endoscopy

This prospective observational study aims to validate the BBCMADE nomogram (Body Mass Index, Brain infarction, Cirrhosis, Male sex, Age, Diabetes, Esophageal reflux) for predicting high-risk gastric content in patients undergoing elective sedative gastrointestinal endoscopy in a Turkish population. Nomogram-predicted risk scores will be compared against the gold standard - endoscopically measured gastric volume and content. High-risk gastric content is defined as gastric volume ≥25 mL, pH \
