title: Patch esophagoplasty with a free proximal lateral leg flap for focal stricture of the cervical esophagus: A case report.
abstract: Esophageal stricture after surgery or trauma is a major reason for poor oral nutrition, body-weight loss, and general damage to health. Patch esophagoplasty, after repeated failed dilation attempts, is recommended for focal esophageal strictures. In this report, we present a case in which a free proximal lateral leg flap was used for reconstruction of focal stricture of the cervical esophagus. A 62-year-old man developed progressive dysphagia after hypopharyngeal cancer ablation and adjuvant radiotherapy. He was referred for surgical interventions after repeated failed dilation attempts. Preoperative evaluation revealed a 3-cm segment stricture of the cervical esophagus without evidence of an additional distal stricture. Patch esophagoplasty with free tissue transfer was planned. After the stricture site had been explored, the fibrotic tissue was resected. A pathology report confirmed no evidence of malignancy. The resultant defect in an otherwise healthy posterior esophageal wall was reconstructed using a proximal lateral leg flap. Recovery was uneventful and the functional outcome was satisfactory at the 6-month follow-up. For the radiated patients with cervical esophageal focal strictures, we introduced a novel use of the proximal lateral leg flap in patch esophagoplasty because of its unnoticeable donor site morbidity and its thin and pliable nature. © 2016 Wiley Periodicals, Inc.
