Comparison of postpyloromyotomy feeding regimens in infantile hypertrophic pyloric stenosis
1Department of Paediatric Surgery, Alder Hey Children's Hospital, Liverpool, UK.
Insights
For infants undergoing pyloromyotomy, delaying feeding for 18 hours post-operation reduces vomiting. This feeding schedule also achieves full oral feeding as quickly as earlier feeding times.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Clinical Nutrition
Background:
- Pyloromyotomy is a surgical procedure for infantile hypertrophic pyloric stenosis.
- Optimal postoperative feeding protocols are crucial for infant recovery.
- Early feeding after surgery can lead to complications like vomiting.
Purpose of the Study:
- To determine the optimal time for reintroducing feeds after pyloromyotomy in infants.
- To compare the effects of early versus delayed feeding on postoperative outcomes.
Main Methods:
- Prospective study involving 100 infants undergoing pyloromyotomy.
- Infants were randomized into two groups: feeding at 4 hours or 18 hours post-operation.
- Outcomes assessed included frequency of postoperative vomiting and time to achieve full oral feeding.
Main Results:
- The group fed after 18 hours experienced significantly less postoperative vomiting compared to the early feeding group (4 hours).
- Both feeding groups achieved full oral feeding in a similar number of days.
- No significant difference in the time to achieve full oral feeding between the groups.
Conclusions:
- Delaying the reintroduction of feeds until 18 hours after pyloromyotomy is recommended.
- This delayed feeding strategy minimizes postoperative vomiting without prolonging the time to full oral feeding.
- Evidence supports an 18-hour feeding interval for improved recovery after pyloromyotomy.
Abstract:
One hundred infants undergoing pyloromyotomy were studied prospectively to ascertain the optimum time at which to reintroduce feeds after operation. The babies were randomized to be fed after 4 or 18 h and were then assessed by monitoring the frequency of postoperative vomiting and the number of days taken to achieve full oral feeding. There was significantly more postoperative vomiting in the early group, while both groups required the same number of days to achieve full oral feeding. The conclusion reached was that a delay in the reintroduction of feeds until 18 h after pyloromyotomy is to be recommended.
