Timing of gastrostomy insertion in children with a neurodisability: a cross-sectional study of early versus late intervention

摘要

Objectives The aim of the study was to assess whether gastrostomy placement before 18?months of age results in a greater increase in z-score for weight and to assess whether admission rates were reduced postgastrostomy in this age group. Design Retrospective cross-sectional study. Setting Single-centre secondary care District General Hospital. Participants All children with a neurodisability with a gastrostomy in situ in September 2011 were included. Those with primary neoplasia and undergoing chemo or radiotherapy or being palliated for an aggressive neurodegenerative disorder were excluded. Those with cystic fibrosis, primary congenital heart disease or Inflammatory bowel disease were also excluded. Forty-one children underwent final analysis. Twenty-four children underwent gastrostomy insertion less than 18?months and 17 children were older than 18?months. Primary and secondary outcome measures Primary outcome was z-scores for weight immediately pregastrostomy and 12?months postgastrostomy. Secondary outcomes were hospital admission rates pregastrostomy and postgastrostomy. Values were compared for those with gastrostomy insertion less than or equal to 18?months against those older than 18?months at insertion. Results Z-score for weight increased significantly in both age groups. There was significantly increased mean difference in the z-score for weight of +1.33 pregastrostomy and postgastrostomy in the less than 18?months age group as compared with an increased mean difference in the z-score for weight of +0.45 in the older age group (p=0.021). There was no significant difference in the admission rates postgastrostomy insertion in either age group. Conclusions Gastrostomy insertion before 18?months of age results in greater z-score for weight gain in children with a neurodisability. This conclusion is limited by the lack of height and skin-fold thickness measurements. Further long-term matched control studies are required to determine the neurodevelopmental and clinical benefit of early gastrostomy placement in such children.
