Gastrostomy buttons for feeding children on continuous cycling peritoneal dialysis.

The promotion of growth in infants and young children with chronic renal failure (CRF) requires an aggressive approach to feeding, often in combination with early dialysis. Supplementary feeding has usually involved the use of nasogastric tubes, but these can have many problems. We report our experience with a gastrostomy button device (Bard Ltd.) for long term feeding. Ten children (7 male) had an initial gastrostomy catheter inserted at a median age of 2.0 years (range 0.25-8.5 years). None of the children required an operation for gastrooesophageal reflux and 6 had placement of the gastrostomy catheter at the time of insertion of the Tenckhoff catheter for continuous cycling peritoneal dialysis (CCPD). The catheter is usually exchanged for a similar sized (18 gauge) button device after 4 weeks. All ten children received CCPD in addition to overnight feeding using an enteral feeding pump. The buttons have been in use for a mean of 12 months (range 2-33 months) and are only changed if the anti-reflux valves fail. Nutritional goals have been achieved and growth parameters maintained or improved in 9 children. The button has many advantages over nasogastric tubes or gastrostomy catheters. It has been welcomed by our families in reducing the stress of feeding these young children.
