Rapid repair of percutaneous endoscopic gastrostomy tubes using three-dimensional printing: A case series

Presented are four cases involving urgent interventions to repair PEG tube failures in PEG dependent patients. We report on the practical utility of 3D printed devices designed for contingency repair of pediatric PEG tubes when other options, including surgical approaches or manufacturer supplied repairs, were not possible. The patients were dependent on PEG for nutrition and/or medication, treated at the University Hospital Limerick or Children's Hospital Ireland – Crumlin, Ireland. Each were unsuitable for surgery. PEG tube fractures occurred in 4 children (2 female, 2 male; aged 6–15 years) with chronic complex medical conditions at 5-6 years dwell time. In each case novel sealing devices were created and customized to address fractured PEG tubes. The designs were 3D printed using biocompatible materials. The PEG tube fractures were effectively sealed with the 3D printed devices within 24 h, and tube potency was completely restored in one case for up to 205 days.
