Objectives: Gastrostomy placement is frequently performed in pediatric patients who require long-term enteral tube feeding. Evidence on the influence of gastrostomy placement on gastro-oesophageal reflux disease has been inconsistent. The aim of this study was to investigate the influence of gastrostomy on gastro-oesophageal reflux., Methods: A prospective, longitudinal cohort study was performed including 50 patients who underwent laparoscopic gastrostomy between May 2012 and April 2014. Before and 3 months after surgery 24-hour multichannel intraluminal impedance pH monitoring was performed and caregivers filled out reflux symptom questionnaires., Results: Gastro-oesophageal reflux symptoms were present in a comparable number of patients before (44%) and after gastrostomy placement (40%; P = 0.73). Twenty-five of the patients (50%) underwent both the preoperative and postoperative tests and were included in impedance-pH analysis. Acid exposure time (percentage of time with pH below 4) did not change significantly after gastrostomy placement: from 6.2% (3.0-18.1) to 6.1% (2.6-14.9). The number of reflux episodes did not significantly change, for either liquid [mean difference 4.3 (-4.5 to 13.2)] or mixed liquid-gas reflux [mean difference 2.0 (-9.3 to 13.3)]. Before gastrostomy placement, 18 out of 25 patients had pathological reflux (72%) on pH-impedance measurement. In 4 patients, pathological reflux dissolved, whereas 4 patients newly developed pathological reflux. A low preoperative weight-for-height percentile was associated with increased acid exposure after gastrostomy placement., Conclusions: Overall, gastrostomy placement was not associated with an increase in acid exposure on 24-hour multichannel intraluminal impedance pH monitoring. Similarly, the prevalence of gastro-oesophageal reflux-related symptoms did not change after gastrostomy.

Introduction: A gastrostomy placement (GP) is an established treatment to provide enteral feeding in pediatric patients with feeding difficulties aiming to improve nutritional status and health-related quality of life (HRQoL). The aim of this study was to evaluate HRQoL in children with severe feeding difficulties who have undergone GP., Materials and Methods: A cross-sectional study was performed including 128 patients who had undergone laparoscopic GP (2004-2011). HRQoL was evaluated using the validated Pediatric Quality of Life 4.0 Inventory. Multiple regression analysis was performed to identify predictors of HRQoL., Results: After a mean follow-up of 4.0 years (interquartile range 2.9-6.2) after GP, mean HRQoL was 53.0 out of 100 (standard deviation 21.1). HRQoL was significantly lower in children with neurologic impairment, with a mean difference of -21.4 points between neurologically impaired and neurologically normal children (p < 0.001). HRQoL was also lower in children with cardiac disease (-19.0 points; p = 0.01) and in children with a history of previous gastrointestinal surgery (-15.2 points; p = 0.03). Feeding through a gastrojejunostomy tube (-33.0 points; p = 0.01) and higher age at the time of operation (-1.2 points per year; p = 0.03) were also associated with lower HRQoL. GP-related complications requiring reintervention were associated with lower HRQoL, although this association was not statistically significant (p = 0.06)., Conclusions: Children with severe feeding difficulty, who have undergone GP, have significantly lower HRQoL compared to a healthy pediatric population. Neurologic impairment, cardiac disease, a history of gastrointestinal surgery, older age, and the need for jejunal feeding through the gastrostomy were predictive of even lower HRQoL.
