Abstract

Hypertrophic pyloric stenosis (HPS) is a common entity with an incidence of 2–4 per 1000 live births. Current definitive treatment is with pyloromyotomy, which is usually performed laparoscopically. The procedure is generally well tolerated with resolution of the patient’s symptoms. In a small percentage of patients, however, there is recurrent vomiting which warrants further investigation. In this pictorial review, the expected post-operative appearance of the pylorus will be described, and the imaging findings and clinical course of two patients with recurrent vomiting after pyloromyotomy will be presented.
