Pharyngoesophageal diverticuli: diagnosis, incidence and management.

Purpose Of Review: Pharyngoesophageal diverticuli such as Zenker's diverticulum are relatively rare diseases that may have a significant impact on a patient's quality of life. Open surgical techniques have historically been the mainstay of treatment for Zenker's diverticuli and remain the preferred approach for many surgeons operating on Killian-Jamieson diverticuli (KJD) and pharyngoceles. However, advances in technology in recent decades have allowed for the development of successful endoscopic surgical techniques for the management of these conditions.

Recent Findings: Endoscopic management of Zenker's diverticulum with carbon dioxide laser-assisted diverticulotomy or endoscopic stapler-assisted diverticulostomy has gained wide acceptance in recent years. This is based on studies showing high rates of successful outcomes, low rates of complications and shorter operative time with an associated impact on overall cost and patient recovery. Endoscopic management of KJD and pharyngoceles has recently been described, but remains controversial with many surgeons preferring open surgical approaches for the ability to identify and protect the recurrent laryngeal nerve.

Summary: Open and endoscopic techniques are accepted for the treatment of Zenker's diverticulum with open approaches remaining the traditional technique for management of non-Zenker's diverticulum. Further investigation of endoscopic approaches for management of KJD is necessary to assess safety and efficacy.
