General Information About Zenker's Diverticulum
Disease Details and Frequently Asked Questions
It is a pathological herniation presenting as a balloon-like pouch (or sac) protruding outward through an anatomical weak point (Killian's triangle) in the muscular wall of the lower pharynx, exactly where it transitions into the esophagus.
During the process of swallowing food or liquids, a significant portion of the bolus bypasses the normal esophageal route and improperly fills and becomes trapped within this weak pouch. It is predominantly observed in the elderly population (individuals over 60 years of age).
Patients experience a persistent sensation of a lump or obstruction in the throat, dysphagia (difficulty swallowing), the sudden spontaneous regurgitation of completely undigested food ingested hours prior, and notably severe halitosis (bad breath) resulting from the putrefaction of trapped food particles within the sac.
The accumulated stagnant food and liquid within the diverticulum pose a high risk of spilling over and being inadvertently inhaled into the trachea (windpipe) and lungs, particularly when the patient assumes a supine position at night. This micro-aspiration frequently triggers a highly dangerous and potentially fatal pulmonary infection known as aspiration pneumonia.
Standard endoscopy (inserting a camera) carries a high risk of iatrogenic perforation because the instrument may inadvertently enter and puncture the blind pouch. The gold standard diagnostic modality is a Barium Swallow Study (Barium Esophagogram). The patient swallows a radiopaque barium contrast liquid while real-time fluoroscopic X-rays are taken; the diverticular pouch rapidly fills with the contrast material, vividly highlighting its exact size and location.
The pouch cannot be eradicated via pharmacological therapy; surgical intervention is the only curative approach. In contemporary practice, rather than an open neck incision, the procedure is predominantly performed endoscopically through the patient's mouth. The intervening muscular septum separating the diverticulum from the esophageal lumen is divided (using an endoscopic stapler or laser), effectively unifying the pouch with the esophagus to allow unobstructed food transit. The procedure is brief, and the patient can typically resume normal oral intake the following day.
