title: Is there any correlation between radiologic findings and eradication of symptoms after pyloromyotomy in hypertrophic pyloric stenosis?
abstract: BACKGROUND
  Hypertrophic pyloric stenosis (HPS) is one of the most common gastrointestinal disorders during early infancy, with an incidence of 1-2:1000 live births in the world. In this study, we aimed to investigate the correlation between radiologic findings and eradication of symptoms after pyloromyotomy in HPS.
  
  
  METHODS
  One hundred and twenty-five (102 boys and 23 girls) patients with suspected infantile HPS were treated surgically by Ramstedt pyloromyotomy between March 21, 2004 and March 20, 2014 at paediatric surgery ward of Tabriz Children's Hospital, Iran. The demographic features, clinical findings, diagnostic work-up, operation type and postoperative specifications of the patients were studied retrospectively.
  
  
  RESULTS
  Male to female ratio was 4:1. The patients were 16-90 days of old and the mean age was 39 ± 1.42 days. The range of pyloric canal length was 7.60-29.00 mm and the mean length was 19.54 ± 3.42 mm. Pyloric muscle diameter was 2.70-9.00 mm, and the mean diameter was 4.86 ± 1.14 mm. Seventy-two percent of patients had episodes of vomiting after operation. Mean time of persistence of vomiting after pyloromyotomy was 15.73 ± 0.15 h. Mean discharge time was 55.22 ± 0.08 h. Radiologic findings did not show any significant correlation with persistence of vomiting or discharge time.
  
  
  CONCLUSIONS
  The present study revealed that radiographic findings could not predict postoperative symptom eradication after pyloromyotomy in HPS.
