EVOLVING ASYMMETRIC HYPERTROPHIC PYLORIC-STENOSIS ASSOCIATED WITH HISTOLOGIC EVIDENCE OF EOSINOPHILIC GASTROENTERITIS

The most frequently occurring and important cause of gastric outlet ob struction in the neonate and young infant is infantile hypertrophic py loric stenosis (IHPS). A reported association of IHPS and eosinophilic gastroenteritis [1] raises interesting questions about the possible e tiologic relationship between the two entities. It is plausible that t he observed sonographic pyloric muscular wall thickness in IHPS may in part be dependent on the degree and duration of an allergic gastroent eropathy. A recent report suggests that endoscopy may be a more reliab le diagnostic method than sonography in the patient with evolving IHPS [2]. Our recent experience with a patient with evolving IHPS supports the findings described in these prior reports.
