Per-oral endoscopic tunneling for restoration of the esophagus (POETRE) in the management of a complete esophageal obstruction

摘要

A 54-year-old man with laryngeal carcinoma treated with laryngectomy and adjuvant chemoradiotherapy was referred for management of a long complete post-radiotherapy cervical esophageal obstruction. Previously, he had undergone successive endoscopic dilatations at another institution; due to loss of follow-up, he was now presenting with total aphagia.
