Retrograde approach to pharyngo-esophageal obstruction

摘要: Abstract Background: The entrance of the esophagus has to be identified for treatment a pharyngo-esophageal obstruction. If transoropharyngeal identification is unsuccessful, retrograde approach might indicated. Methods: By way mini-laparotomy and gastrotomy, flexible gastroscope can passed into esophagus. In one patient with Zenker's diverticulum, guidewire was inserted through accessory channel stenosis, caused by marked hypertrophy cricopharyngeal muscle, oral cavity. Thereafter antegrade dilatation laser assisted myotomy could performed. another membranous obstruction esophageal due radiotherapy, occlusion perforated transoropharyngeally bluntly dilatated guided light from gastroscope. Results: both cases passage restored. No complications occurred as result procedures. Conclusions: may good alternative when fails.
