A Zenker's diverticulum is an out-pouching of the upper hypopharyngeal mucosa between the inferior constrictor muscle and the cricopharyngeus muscle and often leads to dysphagia, foul breath, cough, aspiration, and regurgitation. Excision with concomitant myotomy is first-line therapy. The operation is undertaken along the anterior border of the sternocleidomastoid muscle. The dissection is carried through the neck musculature and ultimately the diverticulum is dissected about its base and transected along its neck utilizing a stapling device. Then, the myotomy of the cricopharyngeal muscle is carried cephalad to the most caudal extent of the staple line, with our goal being an 8cm myotomy. The wound is closed along anatomical layers utilizing absorbable sutures and the skin is approximated. Postoperatively, an upper GI study documents prompt emptying of the esophagus and absence of leak. Patients begin a diet on the day of their operation and are discharged from the hospital the following day. The treatment of choice for Zenker's diverticulum is diverticulectomy, taking care to undertake a complete concomitant myotomy of the cricopharyngeus muscle to prevent recurrence and relieve dysphagia.
