Insights
Endoscopic balloon dilatation offers a new treatment for infant hypertrophic pyloric stenosis (HPS). This minimally invasive procedure successfully resolved vomiting in a patient with HPS after omphalocele repair.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Minimally Invasive Procedures
Background:
- Hypertrophic pyloric stenosis (HPS) is a common cause of infant vomiting.
- Surgical pyloromyotomy is the traditional treatment for HPS.
- This study explores an alternative endoscopic approach.
Observation:
- A single infant girl with HPS, post-giant omphalocele repair, was treated.
- Initial endoscopic balloon dilatation with an 8-mm dilator was ineffective.
- A subsequent dilatation with a 12-mm dilator enabled endoscopic passage.
Findings:
- Endoscopic balloon dilatation was successfully applied to treat HPS.
- The patient experienced complete resolution of vomiting after the second dilatation session.
- The 9-mm endoscope successfully passed the pylorus post-dilatation.
Implications:
- Endoscopic balloon dilatation is a viable therapeutic option for select HPS patients.
- This technique may offer a less invasive alternative to surgery.
- Further research is warranted to establish the long-term efficacy and safety of this method.
Abstract:
The authors successfully applied endoscopic balloon dilatation for the treatment of hypertrophic pyloric stenosis (HPS). The patient was an infant girl who had undergone repair of a giant omphalocele. Endoscopic balloon dilatation was performed using a 9-mm endoscope and an 8-mm polyethylene terephthalate (PET) balloon dilator. Dilatation was performed three times for 10 minutes. Vomiting continued after the dilatation. At the second session, dilatation was performed using a 12-mm PET balloon dilator. The 9-mm endoscope then passed through the pylorus. The patient has had no episodes of vomiting since the second treatment. This procedure is an important therapeutic option for selected patients with HPS.
