Intramural esophageal dissection due to pharyngeal abscess treated by endoscopic esophageal transection: a case report.

Intramural esophageal dissection is a rare disorder characterized by extensive laceration between the mucosal and submucosal layers of the esophageal wall, but without perforation. The etiology of intramural dissection of the esophagus remains uncertain. Conservative management is usually considered adequate. Only one case of circumferential intramural esophageal dissection has been reported previously. We report here on a case due to an infectious cause (paryngeal abscess) that is also an unusual example of circumferential intramural esophageal dissection, which was then treated by endoscopic transection of the true internal esophageal wall and bougienage dilation.
