    Abstract:
    BACKGROUND: Epiphrenic diverticula are rare and associated with esophageal motility abnormalities. Their optimal surgical treatment is debated, mortality being 9% in the largest reported surgical series of 33 patients. Our experience with a traditional thoracic approach was reviewed to provide benchmark data against which newer surgical techniques can be measured. METHODS: A retrospective review of 35 patients operated on for epiphrenic diverticula from 1976 to 2005 was conducted. All underwent open transthoracic operations: resection of the diverticulum, long esophagomyotomy, and antireflux operations (modified Belsey, 29 patients; Nissen, 4 patients) in 33 patients; resection and long myotomy alone in 1 patient; and plication, long myotomy, and Collis-Nissen in 1 patient. Preoperative assessment included barium esophagogram, flexible esophagoscopy, manometry, and standard acid reflux test. Operative complications and functional results were assessed. RESULTS: Median age was 71 years (range, 36 to 87 years). Diverticulum size averaged 6.4 cm (range, 3 to 14 cm). Sixty-eight percent presented to the right of the esophagus. The median duration of symptoms was 3 years. Presenting complaints included dysphagia (83%), regurgitation (69%), and chest pain (26%). Eighteen had a mean weight loss of 19 pounds. There was 1 perioperative death (2.8%) from a plicated diverticulum leak and one nonfatal suture line leak. Median hospital stay was 7 days. Mean follow-up was 45.3 months. Twenty-six patients (74%) had an excellent result (no residual symptoms). Seven required a periodic esophageal dilatation for intermittent mild dysphagia. CONCLUSIONS: Traditional transthoracic resection, long esophagomyotomy, and an antireflux procedure provide excellent long-term functional results with relatively low postoperative morbidity in patients with epiphrenic diverticula.
