Zenker's Diverticulum

Zenker's diverticulum is a type of esophageal diverticulum, which is an outpouching or pouch-like structure that forms in the wall of the esophagus. It is named after the German physician Friedrich Albert Zenker, who first described the condition in 1877.

Causes and Risk Factors

Zenker's diverticulum is thought to be caused by a combination of factors, including:

• Weakening of the muscular wall of the esophagus
• Increase in pressure within the esophagus
• Abnormal contractions of the esophageal muscles
• Gastroesophageal reflux disease (GERD)
• Aging

Symptoms

The symptoms of Zenker's diverticulum can vary, but common ones include:

• Dysphagia (difficulty swallowing)
• Regurgitation of food
• Aspiration pneumonia (inhalation of food or liquids into the lungs)
• Coughing or choking while eating
• Weight loss
• Halitosis (bad breath)

Diagnosis

Zenker's diverticulum is typically diagnosed using a combination of the following tests:

• Barium swallow: a radiographic study that uses barium to visualize the esophagus and detect any abnormalities
• Endoscopy: a procedure in which a flexible tube with a camera is inserted through the mouth to visualize the inside of the esophagus
• Esophageal manometry: a test that measures the muscle contractions of the esophagus

Treatment

The treatment for Zenker's diverticulum depends on the severity of symptoms and the size of the diverticulum. Treatment options include:

• Endoscopic treatment: a minimally invasive procedure that uses a flexible tube with a camera to divide the septum between the esophagus and the diverticulum
• Surgical treatment: an open or laparoscopic surgery to remove the diverticulum and repair any underlying muscle weakness
• Dilatation: a procedure that uses a balloon or dilator to stretch the narrowed area of the esophagus

Complications

If left untreated, Zenker's diverticulum can lead to complications such as:

• Aspiration pneumonia
• Malnutrition and weight loss
• Esophageal perforation (tear in the esophagus)
• Diverticulitis (inflammation of the diverticulum)

Prognosis

The prognosis for Zenker's diverticulum is generally good, especially if treated early. With proper treatment, most people can experience significant improvement in symptoms and quality of life.
