Insights
Early feeding after hypertrophic pyloric stenosis (HPS) surgery, with advancement every 2 hours, increased vomiting but shortened hospital stays. This accelerated feeding approach is safe and cost-effective for HPS patients.
Area of Science:
- Pediatric Surgery
- Gastroenterology
Background:
- Hypertrophic pyloric stenosis (HPS) is a common surgical condition in infants.
- Postoperative feeding protocols after pyloromyotomy vary, impacting patient outcomes.
Purpose of the Study:
- To evaluate the impact of different postoperative feeding regimens on outcomes after pyloromyotomy for HPS.
- To determine the optimal feeding strategy balancing vomiting incidence and hospital stay duration.
Main Methods:
- Retrospective review of 223 infants undergoing pyloromyotomy for HPS.
- Comparison of four distinct postoperative feeding regimens with varying NPO times and advancement schedules.
- Analysis of postoperative vomiting, hospital stay duration, and readmission rates.
Main Results:
- Accelerated feeding regimens (starting at 6 hours postoperatively with advancement every 1-2 hours) led to a progressive increase in vomiting incidence and frequency.
- However, these accelerated regimens (Groups C and D) resulted in significantly shorter postoperative hospital stays and lower charges compared to slower advancement (Groups A and B).
- No patients were readmitted for vomiting or dehydration after discharge across all groups.
Conclusions:
- Starting feedings 6 hours postoperatively with accelerated advancement every 2 hours after pyloromyotomy for HPS increases vomiting but not unacceptably.
- This feeding strategy leads to a significantly shorter postoperative hospital stay.
- Accelerated feeding protocols can be safely implemented for HPS patients, offering benefits in terms of hospital resource utilization.
Abstract:
We retrospectively reviewed 223 infants who underwent pyloromyotomy for hypertrophic pyloric stenosis (HPS) at our institution from January 1984 to May 1990. Each patient's postoperative feeding regimen was determined by the attending surgeon. The four distinct regimens used were as follows: A (n = 66): NPO overnight (> 10 h) with cautious feeding advancement every 4 hours x 2, then every 2 hours x 2, then every 1 1/2 hours x 8, then ad lib; B (n = 46): NPO until 6 to 8 hours postoperatively with the same cautious feeding advancement as in A; C (n = 42): NPO until 6 hours postoperatively with accelerated feeding advancement every 2 hours x 8, then ad lib; D (n = 69): NPO until 6 hours postoperatively with accelerated feeding advancement every 1 hour x 12, then ad lib. There were no significant differences in age at diagnosis or degree of dehydration among groups. From group A to group D, there was a progressive increase in amount and incidence of postoperative vomiting, both after the first three feedings and in the total postoperative period. However, patients in groups C and D had a shorter postoperative hospital stay and lower charges than did patients in groups A and B. Following discharge, no patient was readmitted for vomiting or dehydration. We conclude that feedings started 6 hours after pyloromyotomy for HPS with accelerated feeding advancement every 2 hours increases the incidence and frequency of postoperative vomiting, but not unacceptably, and results in a significantly shorter postoperative stay.
