Abstract
BACKGROUND: The development of endoscopic techniques, particularly endoscopic stapling, has led to a re-evaluation of the treatment of pharyngeal pouch. The pathophysiology and treatment of the condition is reviewed. METHODS: An electronic literature search was undertaken on the pathophysiology, history and surgery of pharyngeal pouch (Zenker's diverticulum). These last two terms were used to the search the Cochrane, Medline and Embase databases (from 1966 to date) and the bibliographies of extracted articles. RESULTS AND CONCLUSION: With recognition of the central role of the cricopharyngeus muscle in the pathogenesis of pouch formation, the emphasis on treatment has shifted from diverticulectomy to cricopharyngeal myotomy. Minimally invasive techniques have become established since the advent of endoscopic stapling devices. Although randomized controlled data are lacking, the endoscopic approach appears to offer advantages in terms of a shorter duration of anaesthesia, more rapid resumption of oral intake, shorter hospital stay and quicker recovery. It is associated with excellent success rates and minimal morbidity. Copyright 2004 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd.
