Influence of Percutaneous Endoscopic Gastrostomy on Gastroesophageal Reflux Disease in Children.

OBJECTIVE

To determine if gastroesophageal reflux disease (GERD) is present at long-term follow-up after percutaneous endoscopic gastrostomy (PEG), and to identify factors associated with the occurrence or aggravation of GERD after PEG placement.

STUDY DESIGN

This prospective, observational study was conducted in our single tertiary center over a 13-year period (gastrostomy performed from 1990 to 2003 and follow-up to 2015). Every child who underwent PEG in our center (N = 368) from 1990 to 2003 was eligible. GERD was defined by clinical manifestations requiring antisecretory or prokinetic treatment, occurrence of a GERD-related complication, or the need for antireflux surgery. Outcomes among patients without antireflux surgery were also assessed. Multivariate analysis was used to identify factors aggravating GERD after PEG placement.

RESULTS

A total 326 patients (89%; 56% with a neurologic impairment) were studied with a median follow-up after 3.5 years (range, 2.0-13.5 years). After PEG placement, GERD appeared in 11% of patients and was aggravated in 25% of patients with preexisting GERD. Factors associated with GERD worsening after PEG placement were neurologic impairment and preexisting GERD. Only 53 patients (16%) required antireflux surgery, among whom 22 required surgery in the year after PEG. Neurologic impairment was the only factor significantly associated with the need for antireflux surgery.

CONCLUSIONS

GERD predominantly remains clinically controlled after PEG placement. Routine antireflux surgery at the time of PEG placement is not justified.
