A Trial of Supplemental CO2 Versus Room Air in Percutaneous Endoscopic Gastrostomy

Not Applicable
Completed
Conditions
Pneumoperitoneum
Interventions
Procedure: CO2 insufflation
Procedure: Ambient air insufflation
Registration Number
NCT02619656
Lead Sponsor
University of Utah
Brief Summary

The investigators hypothesize that using carbon dioxide for PEG placement versus using room air will decrease post-procedure pneumoperitoneum as well as improve post-procedure bloating/pain, and waist circumference.

Detailed Description

Background and study aims: Pneumoperitoneum following PEG placement has been reported in up to 60% of cases, and while usually benign and self-limited, it can lead to evaluation for suspected perforation. This study was designed to determine whether using CO2 compared to ambient air for insufflation during PEG reduces post-procedure pneumoperitoneum.

Patients and Methods: Prospective, double blind, randomized trial of 35 consecutive patients undergoing PEG at a single academic medical center. Patients were randomized to insufflation with CO2 or ambient air. Primary outcome was pneumoperitoneum determined by left-lateral decubitus abdominal x-rays 30 min after PEG placement. Secondary endpoints included abdominal distention, pain, and bloating.
