A preventable medical error: Successful management of iatrogenic Zenker's diverticulum perforation.

Introduction And Significance: Zenker's diverticulum is a rare condition characterized by a false diverticulum, as a true diverticulum involves herniation of all wall layers outward. Dysphagia, difficulty in swallowing, is the most common symptom. Diagnosis is primarily made through X-ray studies using contrast material during swallowing.
