Summary
Persistent vomiting after pyloromyotomy in infants may indicate a coexistent hypertrophic antral polyp. This rare condition requires further investigation beyond standard hypertrophic pyloric stenosis treatment.
Area of Science:
- Pediatric Surgery
- Gastroenterology
Background:
- Hypertrophic pyloric stenosis (HPS) is a common cause of infantile vomiting.
- Pyloromyotomy is the standard surgical treatment for HPS.
Observation:
- A case of persistent vomiting post-pyloromyotomy is presented.
- The infant had a coexistent hypertrophic antral polyp.
Findings:
- The hypertrophic antral polyp was identified as the cause of persistent post-operative vomiting.
- This finding highlights a rare complication or co-morbidity in HPS cases.
Implications:
- Consideration of antral polyps in persistent vomiting after HPS surgery is crucial.
- Further diagnostic evaluation may be necessary in refractory cases.
