A frail 79-year-old has regurgitation of undigested food, halitosis, aspiration and a 3 cm Zenker diverticulum on contrast study. Neck extension is limited, making rigid exposure poor. What is the preferred treatment principle?
Flexible endoscopic division avoids the exposure demands of a rigid diverticuloscope and treats the causal septum; the myotomy must be adequate while avoiding perforation and mediastinal injury.
A. Rigid endoscopic stapling despite demonstrably inadequate exposure: Rigid stapling is reasonable only when exposure is adequate; forcing it risks dental, pharyngeal and perforation injury.
B. Flexible endoscopic septotomy with complete cricopharyngeal myotomy: Flexible endoscopic division avoids the exposure demands of a rigid diverticuloscope and treats the causal septum; the myotomy must be adequate while avoiding perforation and mediastinal injury.
C. Open diverticulectomy without cricopharyngeal myotomy: Failure to divide the dysfunctional cricopharyngeus increases leak and recurrence risk.
D. Flexible pouch mucosal ablation without dividing the septal muscle: Ablating lining does not relieve the cricopharyngeal outflow obstruction.
E. Cricopharyngeal botulinum toxin alone as definitive treatment: Botulinum toxin does not eliminate the established 3 cm party wall and is not the definitive choice here.
If flexible expertise were unavailable and the patient were fit for cervical surgery, open diverticulectomy or diverticulopexy with complete cricopharyngeal myotomy would be an appropriate alternative.
