Children with cerebral palsy (CP) can be significantly disabled in terms of their ability to suck, chew and swallow. This can lead to significant impairment in feeding ability and, eventually, to under-nutrition. It can also result in aspiration of food into the lungs. Feeding time may be considerably increased and, instead of being an enjoyable experience, mealtimes may be distressing for both the child and carer. Increasingly for children unable to maintain a normal nutritional state feeding by mouth, gastrostomy or jejunostomy tubes are being used to provide the digestive system with nutrients. A gastrostomy tube is a feeding tube inserted surgically through the abdominal wall directly into the stomach. A jejunostomy feeding tube is inserted into the jejunum, part of the small intestine, either directly or via a previous gastrostomy. Although gastrostomy or jejunostomy placement may greatly facilitate feeding of children with CP, many carers find it very difficult to accept this intervention emotionally. The treatment is also relatively costly. For all of these reasons, its effectiveness requires assessment.
