摘要

AIM To elucidate the safety of percutaneous endoscopicgastrostomy （PEG） under steady pressure automaticallycontrolled endoscopy （SPACE） using carbon dioxide （CO2）. METHODS： Nine patients underwent PEG with a modifiedintroducer method under conscious sedation. A T-tubewas attached to the channel of an endoscope connectedto an automatic surgical insufflator. The stomach wasinflated under the SPACE system. The intragastricpressure was kept between 4-8 mmHg with a flow of CO2at 35 L/min. Median procedure time, intragastric pressure,median systolic blood pressure, partial pressure of CO2,abdominal girth before and immediately after PEG, andfree gas and small intestinal gas on abdominal X-raybefore and after PEG were recorded.RESULTS： PEG was completed under stable pneumostomachin all patients, with a median procedural timeof 22 min. Median intragastric pressure was 6.9 mmHgand median arterial CO2 pressure before and after PEGwas 42.1 and 45.5 Torr （NS）. The median abdominal girthbefore and after PEG was 68.1 and 69.6 cm （NS）. A mildfree gas image after PEG was observed in two patients,and faint abdominal gas in the downstream bowel wasdocumented in two patients.CONCLUSION： SPACE might enable standardized pneumostomachand modified introducer procedure of PEG.
