Endoscopic treatment in a case with extensive spontaneous intramural dissection of the oesophagus

Abstract

Spontaneous intramural dissection of the oesophagus has been recognized as a separate clinical entity between a transmural oesophageal rupture (Boerhaave syndrome) and an oesophageal mucosal tear (Mallory-Weiss syndrome). It is important to differentiate this condition from myocardiac infarction, dissecting aneurysm and other acute surgical conditions. Conservative management is usually thought to be adequate. We report a case of spontaneous intramural oesophageal dissection, in which the symptom of dysphagia did not improve with the conservative management and an endoscopic incision of the septum between true and false lumens using a needle-type diathermy knife was done safely and effectively.
