Per-oral Pyloromyotomy for Treating Infantile Hypertrophic Pyloric Stenosis

Per-oral Pyloromyotomy for Treating Infantile Hypertrophic Pyloric Stenosis

Infantile hypertrophic pyloric stenosis (IHPS) is the most common condition for surgical treatment in infant. Traditionally, laparoscopic or open pyloromyotomy are the standard treatments. However, because of severe dehydration, electrolyte disturbance, and malnutrition, these patients have lower tolerance about surgery and recover more slowly than usual. We are going to study the per-oral pyloromyotomy (POP), also named as gastric per-oral endoscopic myotomy (G-POEM), which showed promising results for adult gastroparesis, for a novel application of treating IHPS.

Inclusion Criteria:

• Clinical diagnosis of pyloric stenosis with or without sonographic confirmation.

Exclusion Criteria:

• Comorbid conditions that could affect postoperative recovery.
• Needed an additional procedure during the same anaesthetic.
