Killian–Jamieson diverticulum

The Killian - Jamieson diverticulum is like the much more common Zenker 's diverticulum is a pulsion at the upper esophageal sphincter. It has its origin, however. Immediately below the sphincter and is therefore contrary to the Zenker's diverticulum actually a diverticulum of the esophagus

Killian - Jamieson diverticulum can as a permanent form ( diverticula in the resting phase between two sip files visible ) with the transient Pouches this region (only during swallowing prominent ) are summarized.

The localization ventrolaterally results immediately below the cricopharyngeus muscle or posteriorly through the Disclaimer Triangle through the anatomical weaknesses here. Contributory cause pressure spikes between individual muscles of the upper portion of the esophagus.

Killian - Jamieson diverticulum rarely reach a size of more than 1.5 cm. Divertikelträger are usually asymptomatic, which is explained by the fact that any impacted food particles can not enter as in Zenker 's diverticulum upward into the pharynx or in the airways.
