Primary Outcome Measures

Name	Time	Method
To determine the time to emergence with LMA Gastro and endotracheal tube based general anesthesia during ERCP procedures. (primary objective) Co-primary outcome would be incidence of significant respiratory adverse events. <br/ ><br>The recovery time will be noted from the time of extubation to shifting of the patient from endoscopy theatre to recovery room.Timepoint: Primary outcome: The time to emergence with LMA Gastro and endotracheal tube based general anesthesia during ERCP procedures will be done after the procedure once. <br/ ><br>Co-primary outcome: would be incidence of significant respiratory adverse events recorded during the procedure as and when they happen. <br/ ><br>The recovery time will recorded once after the procedure in the recovery room after procedure.

Secondary Outcome Measures

Name	Time	Method
1.Gastroenterologist satisfaction <br/ ><br>2.Number of attempts and first attempt success rate at endoscope insertion. <br/ ><br>3.Anesthetist satisfaction <br/ ><br>4.Number of attempts and time taken at airway device insertion. <br/ ><br>5.Incidence of device insertion failure. <br/ ><br>6.Conversion of one airway device to other during the procedure <br/ ><br>7.Recovery time <br/ ><br>8.Incidence of hypotension, bradycardia, pharyngeal bleed, gastroesophageal reflux and pulmonary aspiration, and post-procedure sore throat. <br/ ><br>Timepoint: 2-6 will be recorded during the insertion of the airway device and endoscope <br/ ><br>1,7&8 will be recorded after the end of procedure
