Ultrasound for G-tube Position in Children

This study is looking at whether ultrasound imaging can accurately check the position of a gastrostomy tube (G-tube) in children. A G-tube is a feeding tube placed directly into the stomach. Researchers want to see if ultrasound is as good as fluoroscopy (a type of X-ray) for this purpose, and if it takes less time. You might be able to join if you are 18 years old or younger, have a G-tube that has recently come out of place, or if your doctor is unsure about its position. The study will compare how well ultrasound imaging agrees with fluoroscopy in identifying the G-tube's location. The current status of this study is unclear, and it plans to enroll 10 participants.

Study design
This is an interventional study, meaning participants will receive a specific intervention (ultrasound imaging). It plans to enroll 10 participants.
What's involved
You will receive ultrasound imaging to check your G-tube placement before your standard fluoroscopy imaging. The study aims to collect all image data within approximately one year.
Compensation
Not stated in the trial record.
Follow-up
The primary endpoint is measured upon completion of all study image data collection for all participants, which is approximately 1 year.

Eligibility criteria

Inclusion

Surgical GT placement less than 90 days from presentation
Traumatic GT dislodgement/removal
Recent stoma dilation
Clinician uncertainty about position of GT placement

Exclusion

An individual \>18 years of age
Acutely ill patients defined as hemodynamically unstable defined as any child who has abnormal vital signs or disruption of vital functions (i.e. airway, breathing, circulation, mental function). Vital signs are based on patient age. Initial assessment of clinical patient stability will be provided by the ordering/referring provider.
  • Proportion of Ultrasound that Agree with Fluoroscopy with Respect to Identifying the GT LocationUpon completion of all study image data collection for all participants [approximately 1 year]

    Proportional accuracy of ultrasound in identifying the gastrostomy tube (GT) balloon location based on the readers' (radiologists) ability to use the ultrasound to locate the GT balloon in comparison with the gold standard (fluoroscopic tube injection).
