The severity of submucosal dissection is intermediate between transmural ru
pture and mucosal tear in the esophagus. We describe a case of submucosal d
issection of the esophagus with characteristic features of mucosal bridge e
ndoscopically and "double-barreled" in radiography. The patient was success
fully treated by intermittent esophageal tamponade of 5-day duration using
a Sengstaken-Blackmore tube, and total parenteral nutrition. His course was
uneventful in a follow-up period of 5 years.
