Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
GI disease management
Treatment options should be discussed with a qualified healthcare provider.
Pyloromyotomy
Surgical division of the hypertrophied pyloric muscle provides definitive treatment by relieving gastric outlet obstruction. This is the gold standard surgical intervention for acquired pyloric stenosis.
Acid Suppression Therapy
Proton pump inhibitors or H2 blockers reduce gastric acid production, decreasing mucosal irritation and improving symptoms of obstruction. Used as adjunctive therapy before definitive treatment.
Additional treatment options
Endoscopic Balloon Dilation
Endoscopic balloon dilation offers a minimally invasive alternative to surgery for select patients with pyloric stenosis. Multiple sessions may be required for adequate symptom relief.
procedureModified Diet
Small, frequent meals with reduced fat content and adequate hydration help manage symptoms while awaiting definitive treatment. Easily digestible foods may reduce gastric irritation.
dietaryNutritional Status and Electrolyte Monitoring
Regular assessment of weight, hydration status, and electrolytes is essential given the risk of malnutrition and metabolic abnormalities from persistent vomiting.
