Clinical Practice Guidelines: Hypertrophic Pyloric Stenosis


Hypertrophic Pyloric Stenosis

This clinical pathway was developed by a consensus group of MCJCHV pediatric surgeons, advance practice providers, and nurses to standardize the management of children hospitalized for Hypertrophic Pyloric Stenosis. Pyloric stenosis is one of the most common surgical conditions of the newborn. The usual age at presentation ranges from 2-8 weeks, with occasional late appearance up to 12 weeks of age, occurring most commonly in males than females. Its cause remains unknown, although genetic predisposition and environmental influences may play a role. Classically, the presentation is one of projectile, non-bilious vomiting. HPS is corrected surgically by Ramstedt pyloromyotomy. This practice guideline addresses the approach to initial evaluation, preoperative optimization, and postoperative management of affected infants. Implementation goals are to streamline the management of these patients and provide high-quality care. We have developed Clinical Decision Support (CDS) tools in the form of order sets to integrate this pathway into our daily practice.
