Traditional conscious sedation for endoscopic retrograde cholangiopancreatography in prone position places patients at risk of desaturation, and high-flow nasal oxygen may reduce the risk. The aim of this study is to evaluate the role of high-flow nasal oxygen during endoscopic retrograde cholangiopancreatography. The investigators will compare the lowest SpO2 of standard nasal oxygen cannula group and that of high-flow humidified oxygen-delivery system group during the procedure.

lowest SpO2 measured with pulse oximetry during the procedure
The investigators will record the lowest SpO2 during the procedure.
Time frame: during the procedure (from the start to the end of the endoscopic retrograde cholangiopancreatography)
incidence of desaturation below 90% during the procedure
The investigators will compare the incidence of desaturation during the procedure between the two groups.
Time frame: during the procedure (from the start to the end of the endoscopic retrograde cholangiopancreatography)
