Core Tip
Core tip: Esophageal diverticula are rare but can cause difficulty in swallowing. They are classified into three major categories according to their pathophysiology and location: epiphrenic diverticulum, Zenker’s diverticulum, and Rokitansky diverticulum, with the former two presenting as clinically significant protrusions and symptomatic cases requiring interventional treatment. However, the esophageal anatomy presents challenges to surgical resection, and the condition itself is not malignant. Therefore, minimally invasive endoscopic treatments have been developed. In this paper, we review the pathophysiology and up-to-date treatment of each diverticulum.
