Over the years, providing anaesthesia at remote locations termed as non-operating room anaesthesia has been steadily increasing and endoscopy suite is one such environment. Although most upper gastrointestinal endoscopies are done under conscious sedation, deep sedation or general anaesthesia is preferred for advanced procedures and interventions like endoscopic retrograde cholangiopancreatography (ERCP).

ERCP is an endoscopic diagnostic and therapeutic procedure widely used for the management of hepatobiliary and pancreatic disorders, which is usually done under tubeless anaesthesia or general endotracheal anaesthesia. Most patients frequently receive tubeless anaesthesia and are found to transition between different depths of anaesthesia. Although, most often safer, significant cardiorespiratory event and hypoxia is known to occur in a few patients. Central to the occurrence of such events is an unsecured airway. Anaesthesia outside operating room makes up a higher proportion of closed claims resulting in death, than in operating room cases and an unsecured airway is shown to have a higher incidence of liability claims related to respiratory events.

Clearly, there is a scope to improve airway and ventilation management during anaesthesia for upper gastrointestinal endoscopic procedures. The LMA^® Gastro™ Airway (Teleflex Medical, Morrisville, NC) is a new laryngeal mask airway specifically designed for upper gastrointestinal endoscopy by Dr. Skinner. This device has a dedicated endoscopy channel (16mm internal diameter), which runs parallel along the airway channel with a terminal cuff. The endoscopy channel ends at the cuff’s distal tip to align with the upper esophageal opening. A well lubricated endoscope can be passed through the channel for endoscopic procedures. Being a recently introduced airway device, there is paucity of literature with respect to its efficacy and this study has not been conducted on Indian population and hence the present study is designed to evaluate its role in ERCP.
