Percutaneous endoscopic primary gastrostomy button (PEG-B) is safe and significantly reduces the need for general anaesthetic tube changes in children when compared to the percutaneous endoscopic gastrostomy tube (PEG-T): a prospective study

Abstract

Purpose To compare the clinical outcomes and financial implications of the percutaneous endoscopic primary button gastrostomy (PEG-B) insertion using T-fastener technique with the percutaneous endoscopic gastrostomy tube insertion (PEG-T) using a push-pull technique. Methods Data were prospectively gathered on 122 patients undergoing gastrostomy insertion over a 3-year period (2016-2019). Our primary outcome measure was the number of second general anaesthetics (GA) required in relation to the gastrostomy tube. Secondary outcome measures included complications and cost. Results Following exclusion criteria of lap assisted, concomitant procedure or insufficient data, 105 patients were analysed. Sixty-two (61%) PEG-B were inserted using a T-fastener technique. Forty-three (39%) PEG-T were inserted using a pushpull technique. Two (3.2%) patients with a PEG-B required a GA change or reinsertion of device compared with 31 (72%) of the PEG-T group who underwent a tube change under GA to either a button or a new tube in the study period (p < 0.01). The requirement for GA changes in the PEG-T group results in a considerably higher cost for this approach than the PEG-B approach. There was no difference between the number of peri-operative and post-operative complications between the two groups; however, the PEG-T group appeared to have higher rate of major operative complications (n = 3 bowel injuries). Whereas in the PEG-B group: complications were minor technical issues and displacement requiring replacement under fluoroscopy. In the follow-up period, rates of granulation tissue requiring intervention and stoma site infections were equivalent between groups. Conclusion The PEG-B technique of placing a gastrostomy avoids the need for a replacement of gastrostomy tube under GA and its associated risk of repeat GA and financial cost. Furthermore, the technique is potentially associated with fewer major complications. We conclude, therefore, that the PEG-B approach reduces the interventional and financial burden on the patient, their family, and the healthcare provider, and could be considered as a safe alternative for paediatric gastrostomy insertion.
