A CASE OF COMPLETE HYPOPHARYNGEAL OBSTRUCTION AFTER BONE MARROW TRANSPLANTATION THAT WAS SUCCESSFULLY TREATED BY ENDOSCOPIC INCISION AND DILATION WITH THE BILATERAL APPROACH

Abstract

A 58-year-old woman was referred to our department for dysphagia as a result of pharyngitis that occurred after bone marrow transplantation. Endoscopic examination revealed complete hypopharyngeal obstruction, and surgical gastrostomy was performed. Then, endoscopic incision and dilation were performed by using a Sato-type curved laryngoscope, transgastrostomic endoscope and oral endoscope under general anesthesia. After the treatment, swallowing became possible. A combined antegrade-retrograde endoscopic approach has low invasiveness and is useful.
