title: Treatment of Zenker's diverticula by cricopharyngeus myotomy under local anesthesia.
abstract: Optimum surgical management of the hypopharyngeal diverticulum is controversial. The authors discuss 48 consecutive patients (average age 72.1 years) with documented hypopharyngeal diverticula who were treated by cricopharyngeus myotomy, leaving the diverticula in situ. All came to the hospital with dysphagia; other symptoms included postdeglutitive cough, regurgitation, aspiration, and weight loss. Seven patients had had previous surgery for a Zenker's diverticulum with recurrence. Aspiration pneumonia was treated in 9 patients; 28 patients had concurrent chronic obstructive pulmonary disease or cardiovascular disease. Thirty-nine patients had cricopharyngeus myotomy under local anesthesia, 5 had cricopharyngeus myotomy under general endotracheal anesthesia, and 4 patients underwent myotomy with a cervical esophagostomy. There was one mortality (2.1%) and no incidence of postoperative bleeding, sepsis, or cranial nerve injury. Follow-up was done with 30 patients via telephone an average of 64 months after operation. Twenty-one of 30 patients reported excellent relief of symptoms, 5 reported improvement with occasional symptoms, and 4 patients described persistent dysphagia. Cricopharyngeus myotomy under local anesthetic is a safe and effective approach to the patient with a hypopharyngeal diverticulum. The awake patient can swallow on command, which enables the surgeon to identify the upper esophageal sphincter (UES) and to perform an accurate, complete myotomy. The absence of a pharyngeal suture line eliminates the risk of leakage and mediastinal sepsis, and allows early, postoperative feeding and discharge.
