Novel hybrid endoscopy-assisted larynx-preserving esophagectomy for cervical esophageal cancer (with video).

Hybrid endoscopy-assisted larynx-preserving esophagectomy is developed for cervical esophageal squamous cell carcinoma encroaching or extending above the upper esophageal sphincter. First, a cervical incision was surgically performed followed by cervical lymph node dissection. Second, the margin of cervical esophageal squamous cell carcinoma was endoscopically identified with iodine staining and marked endoscopically followed by semi-circumferential or circumferential endoscopic full-thickness excision around the lumen of the esophagus. The distal margin was surgically resected and reconstruction was performed. Among six consecutive patients with cervical esophageal squamous cell carcinoma undergoing hybrid endoscopy-assisted larynx-preserving esophagectomy, proximal surgical margin was histologically negative in five patients. During a median follow-up period of 15.5 months, all patients tolerated oral intake and were alive without evidence of recurrence. None of the patients experienced aspiration pneumonia, vocal disorder or postoperative anastomotic stricture. Hybrid endoscopy-assisted larynx-preserving esophagectomy could be a clinically feasible treatment for cervical esophageal squamous cell carcinoma providing accurate proximal resection margin with the benefit of laryngeal function preservation.
