Tu1375 Bowel Preparation With Polyethylene Glycol (PEG) Injection After Upper Gastrointestinal Endoscopy: a Pilot Study

Background and aimsThere is a need to safely achieve conscious sedation during endoscopic retrograde cholangiopancreatography (ERCP). We evaluated the safety and feasibility of a mainstream capnometer system to monitor apnoea during ERCP under CO2 insufflation.MethodsNon-intubated adult patients undergoing ERCP-related procedures with intravenous sedation were enrolled. End-tidal CO2 (EtCO2) was continuously monitored during the procedure under CO2 insufflation using a mainstream capnometer system, comprising a capnometer and a specially designed bite block for upper gastrointestinal endoscopy and ERCP. Oxygen saturation (SpO2) was also monitored continuously during the procedure. In this study, we evaluated the safety and feasibility of the capnometer system.ResultsEleven patients were enrolled. Measurement of EtCO2 concentration was possible from the beginning to the end of the procedure in all 11 cases. There was no measurement failure, dislocation of the bite block, or adverse event related to the bite block. Apnoea linked to hypoxaemia occurred five times (mean duration, 174.4 s).ConclusionThis study confirmed that apnoea was detected earlier than when using a percutaneous oxygen monitor. Measurement of EtCO2 concentration using the newly developed mainstream capnometer system was feasible and safe even under CO2 insufflation.

Present Pilot Study

BACKGROUND: Pulmonary aspiration is a life-threatening complication of upper gastrointestinal endoscopy, the incidence of which has not been determined. Endoscopy-related aspiration has not been studied in procedures in which patients swallow a radiolabelled potential aspirate immediately before endoscopy and undergo nuclear scanning postprocedure.METHODS: A pilot study was conducted in which 200 MBq of non-absorbable technetium-99m phytate in 10 mL of water was administered orally to 50 patients who were about to undergo endoscopy. Gamma camera images were obtained to ensure that there had been no aspiration before endoscopy. After endoscopy, a repeat scan was performed. Fluid aspirated through the endoscope was also collected and analyzed for radioactivity using a hand-held radiation monitor.RESULTS: No evidence of pulmonary aspiration was found in any of the patients studied. The mean estimated percentage of the initially administered radioactivity aspirated through the endoscope was 2.66% (range 0% to 10.3%).CONCLUSION: The present pilot study confirms earlier observations that clinically significant aspiration in the context of upper gastrointestinal endoscopy is uncommon. The incidence of aspiration may, however, be different in acutely bleeding patients undergoing endoscopy. For logistic reasons, this group could not be studied.
