What causes Killian Jamieson diverticulum?

What causes Killian Jamieson diverticulum?

Both Zenker’s diverticulum and Killian-Jamieson diverticulum are caused by anatomical weakness in the hypopharynx or cervical esophagus and dysfunction of the cricopharyngeus muscle [5].

What is Killian dehiscence?

The Killian dehiscence is a triangular-shaped area of weakness in the muscular wall of the pharynx, between the transverse and oblique bundles of the inferior pharyngeal constrictor 1. It is the most common site of pharyngeal diverticula 5.

What is Epiphrenic diverticulum?

Epiphrenic diverticulum is a rare esophageal disorder occurring as an outpouching of mucosa and submucosa through the muscular layers, within 10 cm above the cardia.

What is Zenker’s diverticulum?

Zenker’s diverticulum, also known as pharyngoesophageal diverticulum, is a pharyngeal pouch that forms where the lower part of the throat and the upper part of the esophagus meet. It is most common in older adults.

What is traction diverticulum?

Traction diverticula typically arise in the mid esophagus. A traction diverticulum includes the mucosal, submucosal, and muscular layers of the esophagus; it results from the pull (traction) of an adjacent mediastinal scar, such as those resulting from granulomatous infection.

What is pharyngeal pouch?

A pharyngeal pouch or Zenkers Diverticulum is an outpouching of the pharynx at the level of the larynx (voice Box). Pouches occur in older people and are the result of fibrosis of a band of muscle at the top of the oesophagus callled cricopharyngeus.

What is the importance of Killian’s dehiscence?

Clinical significance It represents a potentially weak spot where a pharyngoesophageal diverticulum (Zenker’s diverticulum) is more likely to occur.

Why is Killian dehiscence called the gateway of tears?

Killian’s dehiscence is a gap between oblique and transverse fibers of inferior constrictor. Significance: A pharyngeal pouch (or Zenkers diverticulum) can be formed by outpouching of pharyngeal mucosa at this site. It is a common site for perforation during esophagoscopy hence called as Gateway of Tears.

Can food get stuck in a pocket in your throat?

A pharyngeal diverticulum puts pressure on the area above your digestive tract when you swallow. Because of this, food and liquids have a harder time going down and passing into the esophagus. Materials can then get stuck in the pouch or your throat. This can cause you to regurgitate your food or drinks.

Is Zenker’s diverticulum serious?

Zenker’s diverticulum is a rare condition that typically affects older adults. It occurs when a pouch of tissue forms where the pharynx meets the esophagus. Mild forms of Zenker’s diverticulum may not require treatment. Treatment for moderate to severe forms of Zenker’s diverticulum typically involves surgery.

Is Zenker’s diverticulum fatal?

Zenker’s diverticulum (ZD) is a benign, rare condition that can have a significant impact on your quality of life because it impairs your ability to swallow food and liquids if left untreated.
