Bi-Lobed Zenker's Diverticulum
-->

In the not so distant past, I saw a patient who suffered from a bi-lobed Zenker's Diverticulum. Zenker's diverticulum for those who don't know is the abnormal development of a pouch in the throat causing symptoms of phlegm in the throat, food regurgitation, swallowing difficulties, and aspiration.

Most Zenker's Diverticulum is composed of a single central pouch. However, there are more rare varieties such as this bi-lobed pouch seen on barium swallow.

However, at time of surgery (endoscopic staple diverticulostomy), the bi-lobed nature of the pouch essentially disappeared.
