Insights
This study introduces balloon dilatation as a new treatment for membranous duodenal stenosis (MDS) in infants. The minimally invasive procedure showed a 100% success rate with no complications, offering a safe alternative to surgery.
Area of Science:
- Pediatric Gastroenterology
- Interventional Radiology
- Neonatal Surgery
Background:
- Membranous duodenal stenosis (MDS) is a rare congenital obstruction.
- Surgical intervention has historically been the primary treatment for MDS.
- A minimally invasive approach for MDS is needed.
Purpose of the Study:
- To describe a novel technique for treating membranous duodenal stenosis (MDS) using balloon dilatation.
- To evaluate the safety and efficacy of per os balloon dilatation in neonates with MDS.
Main Methods:
- Four neonates (2 male, 2 female) aged 8–28 days with MDS underwent duodenal balloon dilatation.
- The procedure was performed under general anesthesia using standard angiography balloons inserted per os.
- Balloon diameters ranged from 6 to 14 mm.
Main Results:
- All four balloon dilatation procedures were technically successful.
- No procedural or post-procedural complications were observed in any patient.
- None of the patients required subsequent surgical intervention, and all are reportedly doing well.
Conclusions:
- Balloon dilatation of membranous duodenal stenosis (MDS) demonstrated a 100% success rate in this initial cohort.
- The technique appears safe and effective, with no complications reported.
- Per os balloon dilatation may be a viable, safe alternative to surgery for MDS, performable by experienced interventional radiologists.
Introduction:
We present a novel approach to the treatment of membranous duodenal stenosis (MDS). To our knowledge this is the first paper to describe balloon dilatation for this entity.
Material And Methods:
Four children, 2 boys and 2 girls, aged between 8 and 28 days, underwent duodenal balloon dilatation. Balloon dilatation was performed under general anaesthesia using standard angiography balloons per os. Balloon diameters ranged from 6 to 14 mm.
Results:
All balloon dilatations were successful. None of the procedures showed procedural or post-procedural complications. None of the patients subsequently required surgical intervention. To date all children are doing well.
Discussion:
The initial experience with balloon dilation of MDS showed a 100% success rate, without procedural or post-procedural complications. The results obtained in this small group of patients suggest that the use of balloon dilatation in cases of MDS may be a safe technique that can be readily performed by an experienced interventional radiologist.
