Introduction: As endoscopic equipment and instruments have improved, the indications for endoscopic treatment have also been extended. This report presents an applicable procedure of endoscopic balloon dilatation for an infant patient with congenital membranous stenosis in the jejunum.
Methods: We used a 9-mm flexible endoscope and a through-the-scope multidiameter balloon catheter in the endoscopic treatment.
Results: Dilatation was performed for dilatation diameters 10, 12, and 15 mm each for 2 min. After carrying out balloon dilatation, the endoscope could be smoothly inserted through the opening.
Conclusion: In upper jejunal stenosis, endoscopic balloon dilatation was minimally invasive and effective as a treatment modality.
