From: Cricopharyngeal myotomy for cricopharyngeus muscle dysfunction after esophagectomy
Schematic of cricopharyngeal myotomy. a Fibrosis occurred in the cricopharyngeus muscle (green dots). The resection line (white line) was demonstrated lateral cricopharyngeus muscle. b When the bilateral cricopharyngeus muscles (arrow) were resected, a disposable endotracheal tube (Inner diameter: 5.5 mm) was inserted in pharingoesophageal region, and the cuff was gradually dilated. The myotomy allowed the dilated mucosa
