Endoscopic retrograde cholangiopancreatography (ERCP) is an imaging procedure that visualizes the drainage ducts of the pancreas, gallbladder, and liver through the use of a duodenoscope and contrast media. By endoscopically identifying the ampulla of Vater, the common bile duct is cannulated. ERCP is also frequently utilized for therapeutic interventions, such as endoscopic sphincterotomy, bile duct stone extraction, stent placement in malignant and benign biliary strictures, and biopsy collection, thus playing a critical role in both the diagnosis and treatment of pancreatobiliary disorders. ERCP, being more invasive than routine upper endoscopies or colonoscopies, typically necessitates deeper levels of sedation. The procedure is performed in the prone, modified prone, or lateral decubitus position, which increases the risk of hypoxemia and hypoventilation due to upper airway obstruction. Furthermore, endoscopic instruments inserted through the oral cavity limit anesthesiologists' access to the patient's airway, thereby restricting ventilation support during gastrointestinal endoscopy. Ensuring airway stability during sedation is paramount for patient safety and procedural efficacy. Currently, a range of devices, including traditional nasal cannulas, high-flow oxygen masks, and procedural oxygen masks, are routinely employed to provide oxygen support throughout the procedure. The existing literature includes randomized controlled trials and systematic reviews aimed at preventing hypoxemia during ERCP. Through this study, investigators aim to make a novel contribution to the literature by assessing the effectiveness of a recently introduced procedural oxygen mask.
