Zenker's diverticulum is usually only treated if it causes significant symptoms, and surgery is the primary mode of treatment. If there are no symptoms, your doctor may recommend waiting until symptoms appear.
The goal of the surgery is to relieve obstruction caused by the diverticulum sac There are two types of surgical options:
- Open surgery: Involves making an incision over the neck and reaching in to remove the sac from the esophageal wall. This is the surgery of choice when the diverticulum is large and cannot be removed by endoscopy.
- Endoscopic approach: Less invasive procedure that uses either rigid or flexible endoscopes. This approach involves cutting into the wall that separates the diverticulum sac from the esophagus, allowing food that goes into the sac to be redirected to the esophagus.
What is Zenker's diverticulum?
A diverticulum is an abnormal pouch-like structure that forms in all parts of the digestive tract. Zenker's diverticulum occurs when the pouch forms at the junction of the pharynx (upper throat) and the esophagus. It is a rare condition affecting between 0.01% and 0.11% of the population.
Zenker's diverticulum is more common in:
- Middle-aged and older adults, especially those between ages 70 to 80
- Men (less common in women)

If left untreated, Zenker's diverticulum can grow and cause complications such as:
- Difficulty swallowing
- Aspiration pneumonia (an infection that occurs when food, saliva, or other matter gets trapped in the lungs)
- Esophageal obstruction
- Vocal cord paralysis
- Squamous cell carcinoma
- Fistulas (an abnormal opening in the digestive tract, leading to leakage of gastric content)
Complications of open surgery may include:
- Nerve damage
- Fistula formation
- Mediastinitis (swelling and inflammation of the chest area between the lungs)
Complications of endoscopy include:
- Dental injury
- Esophageal perforation
- Cervical emphysema (air is trapped in the lower layers of the skin)
