- CoapTech
- Brief Summary
The purpose of this research study is to test a new device called the PUMA-G Pediatric System. The research will measure if the device works well to safely aid doctors placing gastrostomy feeding tubes in children. The PUMA-G Pediatric System is an investigational device that uses ultrasound and magnets to guide insertion of a feeding tube.
- Detailed Description
This is a multi-center, non-randomized, non-blinded feasibility study to evaluate the performance and safety of the Percutaneous Ultrasound Gastrostomy (PUG) technique in the pediatric population.
A common method for placing gastrostomy tubes currently uses ionizing radiation to aid doctors in procedural steps. Excess radiation usage may present long-term risks to pediatric patients. The PUG procedure, using the PUMA-G Pediatric System, primarily uses ultrasound to guide gastrostomy feeding tube placement.
Up to 40 patients will be enrolled in the study and receive the PUG procedure using the PUMA-G Pediatric System. Following the procedure, patients will be followed during their hospital admission until discharge or up to 30 days. Data will be collected to assess how safe the procedure was and if the procedure used less radiation. Study subjects will be compared to a matched, retrospective cohort of patients who received standard of care gastrostomy tube placement by Interventional Radiology.

Group Intervention Description Percutaneous Ultrasound Gastrostomy (PUG) Percutaneous Ultrasound Gastrostomy Enrolled subjects will receive the PUG procedure using the PUMA-G Pediatric System performed by an Interventional Radiologist
- Primary Outcome Measures
Name Time Method PUMA-G Pediatric System Device-Related Complication Rate up to 30 days A composite rate of the quantity and severity of device related adverse events will be quantified (i.e. linking complications to what are caused by the device) in the post-procedural period including any additional medical/surgical interventions to resolve
- Secondary Outcome Measures
Name Time Method Gastrostomy Procedure Complication Rate up to 30 days The rate of other complications during the immediate procedural period between the PUG placement and a historical cohort of matched controls who underwent gastrostomy placement using standard of care Interventional Radiologic gastrostomy tube placement method
Exposure to treatment conditions that pose long term risk to patient health: Anesthesia/Sedative Medications up to 30 days The quantity of anesthesia/sedative medications used during the PUG procedure will be compared to a historical cohort of matched controls who underwent gastrostomy placement using the standard of care Interventional Radiologic gastrostomy tube placement method. Medications and total procedural dosages will be quantified.
Exposure to treatment conditions that pose long term risk to patient health: Ionizing Radiation (Dose Area Product) up to 30 days The quantity of ionizing radiation used during the PUG procedure will be compared to a historical cohort of matched controls who underwent gastrostomy placement using the standard of care Interventional Radiologic gastrostomy tube placement method. Quantities of procedural ionizing radiation will be measured by dose area product (microGy-m2).
Exposure to treatment conditions that pose long term risk to patient health: Ionizing Radiation (Fluoroscopic Time) up to 30 days The quantity of ionizing radiation used during the PUG procedure will be compared to a historical cohort of matched controls who underwent gastrostomy placement using the standard of care Interventional Radiologic gastrostomy tube placement method. Quantities of procedural ionizing radiation will be measured by total fluoroscopic time (min).
Exposure to treatment conditions that pose long term risk to patient health: Ionizing Radiation (Skin Dose) up to 30 days The quantity of ionizing radiation used during the PUG procedure will be compared to a historical cohort of matched controls who underwent gastrostomy placement using the standard of care Interventional Radiologic gastrostomy tube placement method. Quantities of procedural ionizing radiation will be measured by skin dose (mGy).
Exposure to treatment conditions that pose long term risk to patient health: Antibiotic Medications up to 30 days The quantity of antibiotic medications used during the PUG procedure and in the post-procedural timeframe will be compared to a historical cohort of matched controls who underwent gastrostomy placement using the standard of care Interventional Radiologic gastrostomy tube placement method. Medication and dosage will be measured.
