Mic-Key Versus Mini One Family Preference Comparison

This is a single center prospective, randomized study with a crossover design, comparing two low profile balloon gastrostomy buttons (Figure 1), MIC-Key™ and MINI One™ that are routinely used at CMH. Each subject will be randomly assigned to one button type at the time of initial placement. After placement, standard practice is to perform the first gastrostomy change in the clinic at 2 months where the primary caregivers replace the button under supervision. Therefore, the initial device after randomization will remain in place for 2 months. At the first scheduled device change, the other type of button will replace the original gastrostomy button device. This will remain in place for another 2 months. At the routine visit at 4 months the parents will be asked to choose which button they prefer to keep. This will meet the primary outcome endpoint of the study. The investigators will continue to follow as many subjects as possible to 4 years in order to identify any potential differences in secondary end points.

A caregiver satisfaction survey is routinely used in the clinics. Parent responses to this survey will be also be used in the study analysis.
