Abstract

Here, we report a case of corrosive injury-induced pharyngeal stricture in a 69-year-old female, which was successfully treated with endoscopic adhesiolysis using an electrosurgical knife. The patient had ingested sodium hydroxide in an attempted suicide, and immediate endoscopy revealed corrosive injuries of the pharynx, esophagus, and stomach. When a liquid diet was permitted, she complained of nasal regurgitation of food. Follow-up endoscopy revealed several adhesive bands and a web-like scar that did not allow passage of the endoscope into the hypopharyngeal area. For treatment of the hypopharyngeal stricture, the otolaryngologist attempted to perform an excision of the fibrous bands around the esophageal inlet using microscissors passed through an esophagoscope, but this procedure was not effective. We then dissected the mucosal adhesion and incised the adhesive bands using an electrosurgical knife. After this procedure, nasal regurgitation of food no longer occurred. To our knowledge, this case is the first report of endoscopic adhesiolysis with an electrosurgical knife in a patient with a corrosive injury-induced pharyngeal stricture.
