A ferromagnetic T-fastener is often used in children during gastrostomy procedures. We describe the experience with the use of a new gastropexy device (two parallel needles with a snare) that uses a non-ferromagnetic anchor during primary percutaneous retrograde radiologic gastrostomy insertion in four children with a mean age of 6 years and 6 months (range: 2 years and 11 months to 9 years and 6 months). The new gastropexy device was safe and effective in children. It is advantageous for children requiring magnetic resonance (MR) examinations soon after gastrostomy insertion, especially in view of MR-related implications that result from the use of a ferromagnetic T-fastener.
