Short-term weight gain after adenotonsillectomy in children with obstructive sleep apnoea: systematic review.

BACKGROUND

Children with obstructive sleep apnoea commonly undergo adenotonsillectomy as first-line surgical treatment. This paper aimed to investigate whether this intervention was associated with weight gain after surgery in the paediatric population with obstructive sleep apnoea.

METHOD: Two independent researchers systematically reviewed the literature from 1995 to 2014 for studies on patients who underwent adenotonsillectomy with weight-based measurements before and after surgery. The databases used were Ovid Medline, Embase and PubMed.

RESULTS

Six papers satisfied all inclusion criteria. Four of these papers showed a significant weight increase and the others did not. The only high quality, randomised, controlled trial showed a significant increase of weight gain at seven months follow up, even in patients who were already overweight before their surgery.

CONCLUSION

The current evidence points towards an association between adenotonsillectomy and weight gain in patients with obstructive sleep apnoea in the short term.
