#Zenker #diverticulum (ZD) is a relatively uncommon problem
of the #pharyngoesophagus. It occurs predominately in elderly men. The #diverticulum contains only mucosa and submucosa

Alexis Littré (1654-1726), a French physician and anatomist, described a hernia containing a Meckel’s diverticulum (Littré’s hernia). He also described the mucous urethral glands of the male urethra (Littré’s glands).
