Abstract

Abstract : A 43‐year‐old man with complaints of increased difficulty swallowing and weight loss underwent videofluorographic examination of swallowing, which revealed severely reduced cricopharyngeal opening. Endoscopic cricopharyngeal myotomy was carried out using a modified technique (mECPM). A benign fibrotic stricture of the upper esophageal sphincter (UES) was identified under visualization of a distending operating laryngoscope. A vertical midline incision in the strictured mucosa and submucosal resection of the cricopharyngeal muscle were done using a CO2 laser. The initial vertical mucosal incision was tightly sutured in the horizontal direction with absorbable surgical sutures. Histopathological examination of the cricopharyngeal muscle revealed infiltration of inflammatory cells. The patient started oral intake on postoperative day 7. He has been symptom free for 2 years with an improved body mass index, and postoperative laryngoscopy revealed no salivary retention in the piriform sinuses. The technique presented here provides sufficient opening of the UES by eliminating the problem of restenosis. mECPM will be useful for treating benign fibrotic strictures of the UES.
