Endoscopic examination showed no distal stricture or cricopharyngeus muscle.
We expected to find an obstructive stricture or cricopharyngeus muscle as the cause, but none was found upon barium swallow or endoscopic examination.
13) In a small study, percutaneous injection of botulinum toxin into the cricopharyngeus muscle resulted in improvement of swallowing in all treated patients.
A distending diverticuloscope was used to easily expose the cricopharyngeus muscle, esophageal inlet, and mediastinal diverticulum.
Three sequential 35-mm endovascular staplers were used to transect the cricopharyngeus muscle and the entire party wall between the diverticulum and the native esophagus.
6 The usual location of perforation from endoscopy is at the cricopharyngeus muscle but, when esophageal dilation is added to the procedure, the location is usually proximal to or at the stricture.
In most cases, dividing the cricopharyngeus muscle provides excellent symptom relief and allows the pouch to empty completely with swallowing.
A modified barium swallow study showed a slight delay of solid passage just below the cricopharyngeus muscle at the site of the cervical spine hardware, but no significant esophageal compression was noted.
This demonstrated that a partial esophageal obstruction had been caused by the anterior cervical spine hardware below the cricopharyngeus muscle (figure).
Transnasal esophagoscopy detected a 24-cm soft-tissue mass that had originated immediately inferior to the cricopharyngeus muscle and extended into the distal esophagus (figure).
