MCRA of an anastomotic stenosis after esophagoesophagostomy for long gap esophageal atresia: a case report

A 25-month-old boy with long gap esophageal atresia developed severe esophageal stenosis refractory to balloon dilatations after definitive esophagoesophagostomy. At 33 months of age, the patient had a magnetic compression revision anastomosis, in which a pair of 2 cylindrical Samarium-cobalt rare-earth 320 mT (3200 G) magnets, 15 × 5 mm (diameter × thickness), were placed in the esophagus to compress the scar tissue of the anastomosis. The magnets were retrieved 34 days after the magnetic compression revision anastomosis procedure. For 3 months, the patient subsequently had balloon dilatations to prevent restenosis, and he has been able to eat normally by mouth without further balloon dilatations since then.
