Killian–Jamieson diverticulum (original) (raw)
A Killian–Jamieson diverticulum is an outpouching of the esophagus just below the upper esophageal sphincter. 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. 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 weakness in the cervical esophagus just below the cricopharyngeal muscle. It is usually smaller in size than a Zenker's diverticulum, and typically asymptomatic. Although congenital, it is more commonly seen in elderly patients.

| dbo:abstract | Das Killian-Jamieson-Divertikel ist wie das viel häufigere Zenker-Divertikel ein Pulsionsdivertikel am oberen Speiseröhren-Sphinkter. Es hat seinen Ursprung jedoch unmittelbar unterhalb des Sphinkters und ist somit im Gegensatz zum Zenker-Divertikel tatsächlich ein Divertikel der Speiseröhre. Killian-Jamieson-Divertikel können als permanente Form (Divertikel auch in der Ruhephase zwischen zwei Schluckakten erkennbar) mit den transienten Pouches dieser Region (nur während des Schluckens hervortretend) zusammengefasst werden. Die Lokalisation nach ventrolateral unmittelbar unter dem Musculus cricopharyngeus oder nach dorsal durch das Laimer-Dreieck ergibt sich durch die anatomischen Schwachstellen hier. Mitursächlich sind Druckspitzen zwischen einzelnen Muskelpartien der obersten Anteils der Speiseröhre. Killian-Jamieson-Divertikel erreichen selten eine Größe von mehr als 1,5 cm. Divertikelträger sind in der Regel symptomlos, was sich dadurch erklärt, dass eventuell retinierte Speisereste nicht wie beim Zenker-Divertikel nach oben in den Pharynx oder in die Luftwege gelangen können.
