Zenker’s diverticulectomy is a surgical procedure to remove a pouch-like pocket (diverticulum) that can form at the back of the throat, just above the esophagus. This pouch traps food and liquids, leading to symptoms like bad breath, coughing after eating, choking, and difficulty swallowing.

The surgery can be done through the mouth (endoscopic approach) or through an incision in the neck (open approach), depending on the size and location of the diverticulum. In both cases, the pouch is removed or opened into the esophagus, and the tight muscle (cricopharyngeus) contributing to the problem is cut. Recovery typically includes a short hospital stay, a liquid diet at first, and a gradual return to solid foods. Voice and breathing are usually unaffected, and swallowing improves significantly. Risks include infection, bleeding, or leak at the surgical site, though complications are uncommon with experienced surgeons.
