In brief
This pilot study demonstrates that ultrasound imaging is a highly accurate alternative to contrast studies for confirming gastrostomy tube placement in pediatric emergency settings, achieving 96% sensitivity and 100% specificity. The findings support ultrasound as a safer, radiation-free option for high-risk patients requiring emergent tube replacement.
Written by the GCMD Library team from the article.
Background
Gastrostomy tube (GT) dislodgement is a common cause of Pediatric Emergency Department (PED) visits. Postoperative patients and those who require stoma dilation are more likely to have complications during emergent replacement. Although incorrect replacement can cause significant morbidity overall, the occurrence is infrequent. Contrast injection of the GT is considered the standard for confirming proper placement. Case reports in both pediatric and adult patients suggest that ultrasound can be used to confirm proper replacement. The objective of the present study was to assess the utility of ultrasound to confirm GT placement in pediatric patients most at risk for complications from incorrect replacement.
Methods
This is a non-randomized cohort pilot trial to determine the sensitivity and specificity of ultrasound to confirm proper replacement of a GT in a Pediatric Emergency Department.
Results
We enrolled 55 pediatric subjects, of which 50 had ultrasound imaging after GT replacement in the PED prior to contrast injection. Ultrasound was found to have 96% sensitivity and 100% specificity for confirming GT placement.
Conclusions
Ultrasound is a safe and reliable confirmatory study to confirm GT placement in pediatric patients, especially those at highest risk of complications from incorrect placement.
