Zenkerīs diverticulum is easily vizualised by an X-ray-examination, as in these pictures. Endoscopy may be difficult, the patient cannot easily swallow the endoscope, and Zenkerīs diverticulum is one of the reasons for the very rare complications - perforation - during endoscopy. Zenkerīs diverticulum is treated surgically.

 The first known picture of a Zenkerīs diverticulum (the large sac to the left in the picture) in a woodcut published in a book by F. A. Zenker and H. von Ziemssen, Handbuch der Krankenheiten des Chylopoetischen Apparates I, 1877
