BACKGROUND: The optimal management of Zenker's diverticula is controversial in part because of the method of categorizing treatment success or failure. Subjective and objective radiologic tests have been used to evaluate the various treatment modalities. There seems to be poor correlation between subjective and objective findings, and we tested this hypothesis in a group of patients undergoing one form of therapy (diverticulectomy and cricopharyngeal myotomy [CPM]). METHODS: Eighteen consecutive patients underwent Zenker's diverticulectomy and CPM. Postoperative symptoms and abnormalities detected by barium esophagrams were evaluated after a mean follow-up of 30.3 months (range, 7-74 months). RESULTS: Three of 18 patients (17%) complained of dysphagia (2 occasional and not bothersome; 1 bothersome and affecting dietary intake). Postoperative static contrast esophagrams were interpreted without knowledge of the subjective symptoms. Small diverticula were identified in 8 patients (44%). There was poor correlation between symptoms and objective radiographic abnormalities with agreement of 56% and a kappa statistic of 0.23. CONCLUSIONS: Objective radiographic abnormalities are far more common than subjective complaints following diverticulectomy and CPM. Postoperative static contrast radiography is not routinely required and may be misleading because of the poor correlation between symptoms and radiographic findings. The value of dynamic videofluoroscopy needs to be evaluated.
