Repyloromyotomy for recurrent infantile hypertrophic pyloric stenosis after successful first pyloromyotomy.

The authors report on a male infant aged 4(1/2) weeks who underwent a pyloromyotomy for hypertrophic pyloric stenosis. After an uncomplicated postoperative course with normal feeding and weight gain, projectile vomiting reoccurred. The boy underwent a repyloromyotomy for recurrent hypertrophic pyloric stenosis. The underlying cause of a recurrent hypertrophic pyloric stenosis after a successful pyloromyotomy may be explained by the natural history of the disease. Copyright 2002, Elsevier Science (USA).
