Use of 3D printing to create a bespoke repair of a Percutaneous Endoscopic Gastrostomy (PEG) tube in patient unfit for surgical replacement

We report a case of three-dimensional (3D) printing being used to solve a difficult bedside clinical problem and avoidance of substantial risk associated with alternative solutions. A 15-year-old male with advanced cystic fibrosis developed a small (~1mm) linear tear in his Percutaneous Endoscopic Gastrostomy (PEG) tube, approximately 40 mm from the skin surface. The patient’s advanced condition precluded replacement of the PEG tube under general anaesthetic. Attempts to manage the tear with adhesive tapes yielded limited success. 3D printing was used to create a bespoke sealing device overnight, rectifying the leak and allowing enteral feeding to recommence unimpeded. The device is functioning well, several months post-discharge of the patient.
