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 ...
A Killian–Jamieson diverticulum is an outpouching of the esophagus just below the upper esophageal sphincter. [1] The physicians that first discovered the diverticulum were Gustav Killian and James Jamieson. Diverticula are seldom larger than 1.5 cm, and are less frequent than the similar Zenker's diverticula.

It represents a potentially weak spot where a pharyngoesophageal diverticulum (Zenker's diverticulum) is more likely to occur. [1] Eponym
A jejunal diverticulum is a congenital lesion and may be a source of bacterial overgrowth. It may also perforate or result in abscesses. A Killian-Jamieson diverticulum is very similar to a pharyngeal esophageal diverticulum, differing in the fact that the pouching is between the oblique and transverse fibers of the cricopharyngeus muscle.

Barium enema is inferior to colonoscopy in terms of image quality and is usually only performed if the patient has strictures or an excessively tortuous sigmoid colon where colonoscopy is difficult or dangerous. Colonoscopy will show the diverticulum and rule out malignancy. A colonoscopy should be performed 4–6 weeks after an acute episode.

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.
