Current status of minimally invasive endoscopic management for Zenker diverticulum

Core Tip

Core tip: Developments in minimally invasive surgery and interventional endoscopic techniques have led to profound changes in the management of Zenker’s diverticula. Transoral techniques, either through a rigid or flexible endoscopic device, have gained popularity due to the low morbidity, fast recovery time and safe repeatability. However, the choice of treatment is still based on phisician’s expertise, personal preferences, and area of specialty. Endostapling through rigid endoscopy remains the most frequently performed approach. Interventional flexible endoscopy is an attractive minimally-invasive treatment option. However, due to heterogeneity of data and lack of standardized protocols, a direct comparison of the various techniques is difficult. Prospective clinical studies are required to establish treatment guidelines for Zenker diverticulum.
