Hypertrophic pyloric stenosis in an adolescent

Area of Science:

• Pediatric Surgery
• Gastroenterology

Background:

• Hypertrophic pyloric stenosis (HPS) is typically diagnosed in infancy.
• Pyloric stenosis presenting beyond infancy, particularly in adolescents and adults, is rare.
• The underlying etiology of adult-onset pyloric stenosis remains largely unknown.

Observation:

• A 14-year-old male presented with symptoms including nausea, intermittent vomiting, and abdominal pain.
• Diagnostic imaging via upper gastrointestinal series revealed persistent narrowing of the pylorus.
• The patient was referred for surgical evaluation due to the persistent pyloric obstruction.

Findings:

• The patient underwent a laparoscopic pyloroplasty procedure.
• Postoperative recovery was uneventful.
• At 20 months follow-up, the patient remained asymptomatic, indicating successful surgical intervention.

Implications:

• Laparoscopic pyloroplasty is an effective treatment for adolescent-onset hypertrophic pyloric stenosis.
• This case expands the understanding of HPS presentation beyond early infancy.
• Further research into the etiology of late-onset HPS is warranted.
