title: Recurrent pyloric stenosis: to dilate or operate? A preliminary report.
abstract: OBJECTIVE
  Idiopathic hypertrophic pyloric stenosis is a common surgical problem in infants, and pyloromyotomy is almost always successful in alleviating the obstruction. There are few reports in the literature that discuss recurrent pyloric stenosis as opposed to incomplete pyloromyotomy. We report 2 such babies with different cures.
  
  
  METHODS
  The health records department files were electronically searched for the number of infants at our children's hospital with hypertrophic pyloric stenosis seen over the past 30 years (1973-2003), and the recurrences were reviewed.
  
  
  RESULTS
  Recurrent pyloric stenosis was encountered in 2 cases (<0.07%). Balloon dilatation was first tried in both cases and was successful in 1 case; redo pyloromyotomy was required for the second case.
  
  
  CONCLUSIONS
  Recurrent pyloric stenosis is rare. Fluoroscopic balloon dilatation of the pylorus warrants further study as the first choice for curing this problem, and if unsuccessful, redo pyloromyotomy.
