Esophageal obstruction due to extensive intramural esophageal dissection: diagnosis and treatment using an endoscopic...

Intramural esophageal dissection is an uncommon condition which usually responds to conservative management. We report an unusual case of extensive dissection resulting in complete esophageal obstruction, and which required endoscopic therapy. Diagnosis was made using two endoscopes: the transoral endoscope was in the false esophageal lumen, while a second endoscope inserted through a pre-existing gastrostomy was in the true esophageal lumen. Endoscopic needle knife incision of the entire mucosal septum resolved the patient's symptoms, and was performed without complication. The literature is reviewed for current knowledge of this condition. We also propose that 'intramural esophageal dissection' should be the preferred name for this condition, which at present is known by many names.
