Use of an Ultra-slim Gastroscope to Accomplish Endoscopist-Facilitated Rescue Intubation During ERCP: A Novel Approach to Enhance Patient and Staff Safety. Digestive diseases and sciences Barakat, M. T., Angelotti, T. P., Banerjee, S. 2020


BACKGROUND: ERCP is often performed under monitored anesthesia care (MAC) rather than general anesthesia (GA), with patients positioned semi-prone on the fluoroscopy table. Rarely, a MAC ERCP must be converted to GA due to hypoxia or retained food in the stomach. In these circumstances, standard intubation is associated with a significant delay and potential for patient/staff injury during repositioning. We report a novel endoscopist-driven approach to intubation during ERCP using an ultra-slim, flexible gastroscope with an endotracheal tube backloaded onto it.MATERIALS AND METHODS: We identified patients who underwent ERCP from 2014 to 2019, and MAC to GA conversion events. Mode of intubation (standard vs. endoscopist-facilitated) and patient/procedure characteristics were evaluated. All endoscopist-facilitated intubations were performed under anesthesiologist supervision.RESULTS: A total of 3409 patients underwent ERCP; 1568 (46%) GA and 1841 (54%) MAC. Of these, 42 (2.3%) required intubation during ERCP and 16 underwent endoscopist-facilitated intubation due to retained food in the stomach and/or hypoxia. In 3 patients, aspirated material was suctioned from the trachea and bronchi using the ultra-slim gastroscope. Immediate post-procedure extubation was successful in all endoscopist-facilitated intubation patients and none exhibited radiographic evidence of aspiration pneumonia.CONCLUSIONS: Endoscopist-facilitated intubation using an ultra-slim flexible gastroscope is feasible and expeditious for MAC to GA conversion during ERCP. This technique is readily accomplished in the semi-prone position, while standard intubation requires patient transfer from fluoroscopy table to gurney, with associated delay/risks. These data suggest that further study of this approach is warranted, and this may be the most favorable approach for intubation during ERCP.
