Bidirectional esophageal dilatation in pharyngoesophageal stenosis postradiotherapy

摘要: Severely stenosed radiation-induced benign strictures around the level of cricopharyngeus post-radical chemoradiation for head and neck or upper esophageal cancers pose significant management problems. We report our technique bidirectional assessment dilatation pharyngoesophageal in patients with an situ percutaneous endoscopic gastrostomy (PEG) tube. The gastrointestinal surgeon approached area stenosis a retrograde manner through PEG tube to guide otolaryngeal who performed anterograde via rigid laryngoscope. Between 2005 2009, was on 5 at institution. Video fluoroscopy confirmed improved patency esophagus all cases good improvement swallowing ability 4 patients. accurately assess using visualization transillumination is key modification technique. suggest difficult severe stenoses although extreme care required.
