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 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]

Researchers from The Institute of Cancer Research in London have developed a new test that can predict colorectal cancer risk in people with IBD with more than 90% accuracy.
Zenker's diverticulum develops between the two muscular bellies (the thyropharyngeal part and the cricopharyngeal part) in a small gap called Killian's dehiscence. A diverticulum can form where a balloon of mucosa becomes trapped outside the pharyngeal boundaries. Food or other materials may reside here, which may lead to infection.
Esophageal diseases can derive from congenital conditions, or they can be acquired later in life.. Many people experience a burning sensation in their chest occasionally, caused by stomach acids refluxing into the esophagus, normally called heartburn.
(See Zenker's diverticulum) Dysphagia is often a side effect of surgical procedures like anterior cervical spine surgery, carotid endarterectomy, head and neck resection, oral surgeries like removal of the tongue, and partial laryngectomies [10] Radiotherapy, used to treat head and neck cancer, can cause tissue fibrosis in the
