A Zenker's diverticulum, also pharyngeal pouch, is a diverticulum of the mucosa of the human pharynx, just above the cricopharyngeal muscle (i.e. above the upper sphincter of the esophagus). It is a pseudo diverticulum or false diverticulum (only involving the mucosa and submucosa of the esophageal wall, not the adventitia), also known as a ...
Diverticula are seldom larger than 1.5 cm, and are less frequent than the similar Zenker's diverticula. As opposed to a Zenker's, which is typically a posterior and inferior outpouching from the esophagus, a Killian–Jamieson diverticulum is typically an anterolateral outpouching at the level of the C5-C6 vertebral bodies, due to a congenital ...
Diverticula are described as being true or false depending upon the layers involved: False diverticula (also known as "pseudodiverticula") do not involve muscular layers or adventitia. False diverticula, in the gastrointestinal tract for instance, involve only the submucosa and mucosa, such as Zenker's diverticulum. [2]

Diverticular disease can present with painless rectal bleeding as bright red blood per rectum. Diverticular bleeding is the most common cause of acute lower gastrointestinal bleeding. [9] However, it is estimated that 80% of these cases are self-limiting and require no specific therapy. [10]
Zenker is the name of: Friedrich Albert von Zenker (1825–1898) was a German pathologist, who named: Zenker's degeneration; Zenker's diverticulum; Zenker's fixative; Zenker's paralysis; Georg August Zenker (1855–1922), German gardener and naturalist; Hans Zenker (1870–1932), German admiral; Jonathan Carl Zenker (1799–1837), German naturalist
It represents a potentially weak spot where a pharyngoesophageal diverticulum (Zenker's diverticulum) is more likely to occur. [1] Eponym
Barium X-ray examinations are useful tools for the study of appearance and function of the parts of the gastrointestinal tract. They are used to diagnose and monitor esophageal reflux, dysphagia, hiatus hernia, strictures, diverticula, pyloric stenosis, gastritis, enteritis, volvulus, varices, ulcers, tumors, and gastrointestinal dysmotility, as well as to detect foreign bodies.
