Endoscopic fibrin sealing of congenital pyriform sinus fistula
Tóm tắt
Pyriform sinus fistula is a very rare branchial apparatus malformation, often appearing in the form of a cervical inflammatory process (abscess or suppurative thyroiditis), especially in infants. Failure to diagnose this lesion may result in unexpected recurrence. A case of recurrent suppurative thyroiditis caused by pyriform sinus fistula in a 9-year-old girl is reported. In the latency period of infection, the fistula tract was identified by a barium meal contrast study. Direct endoscopy showed the fistula internal orifice at the apex of the left pyriform fossa. The fistula was completely obliterated by injection of fibrin glue. Suppurative thyroiditis is reported mainly in the pediatric literature, and the reported case is the first to be managed endoscopically by injection of fibrin adhesive.
