Aim  The aim of the study was to estimate the influence of percutaneous endoscopic gastrostomy (PEG) placement on gastro‐oesophageal reflux (GOR) by using multiple intraluminal impedance (MII/pH) measurements in children with neurological impairments. Method  Fifteen children with neurological impairments (cerebral palsy, n=10; cerebroidolipofuscinosis, n=2; Aicardi syndrome, n=1; and secondary encephalopathy, n=2) were investigated (interquartile range [IQR] 6y 4mo–14y 8mo; median age 10y 2mo; eight male, seven female). Individuals with nutritional disorders that could not be corrected by physiological means or with swallowing disorders that either caused chronic respiratory symptoms or prevented food intake were included in the study. The exclusion criteria included previous major abdominal surgery and a lack of consent for PEG. Participants underwent MII/pH for a 24‐hour period and had an oesophagogastroduodenoscopy before PEG placement, which was repeated 6 to 8 months later. Results  At baseline, GOR was detected in 6 of the 15 participants, and the second MII/pH session revealed GOR in 2 of the 15 children. Differences between quantitative GOR indices obtained before and after PEG were not statistically significant, except for the proportion of the acidic/weakly acidic reflux events – among all participants in the first examination, 159 reflux episodes were acidic and 244 were weakly acidic, while in the follow‐up recordings the proportion was inverted (244 acidic, 136 weakly acidic; χ2=47.0; p
