Abstract
OBJECTIVES/HYPOTHESIS: We aimed to compare three surgical techniques (open approach for diverticulectomy with cricopharyngeal myotomy [OA], endoscopic laser-assisted diverticulotomy [ELD], and endoscopic stapler-assisted diverticulotomy [ESD]) for treatment of Zenker's diverticulum with regard to validated swallowing outcomes, radiographic outcomes, complications, and revision rates. We statistically analyzed whether the size of residual postoperative party wall or the specific surgical technique correlates with swallowing outcomes. STUDY DESIGN: Retrospective chart review and radiographic study analysis. METHODS: A retrospective chart review and radiographic analysis of preoperative and postoperative contrast swallow studies were conducted on patients undergoing surgery for Zenker's diverticulum between 2002 and 2014 at our institution. A follow-up validated swallowing outcome questionnaire, the Eating Assessment Tool-10, was administered to measure and compare patients' symptomatic outcomes. RESULTS: Seventy-three patients were reviewed and grouped according to technique. Median follow-up was 1.6 years. ESD resulted in a significantly larger residual party wall than ELD and OA but yielded comparative swallowing outcomes. OA had the highest complication rate and ESD had the highest revision rate. There were no revisions after ELD nor OA. CONCLUSIONS: Despite the predictably larger residual postoperative party wall following ESD, this technique produced statistically comparable swallowing outcomes. Given its low complication rate and comparable results, ESD should be considered first line therapy for medically high-risk patients with Zenker's diverticulum, while acknowledging a higher risk of symptom recurrence. ELD, with its slightly greater risk profile but low recurrence rate, is well suited for most in revision cases. OA may best be reserved for those patients in whom endoscopic approach is not feasible. LEVEL OF EVIDENCE: 4 Laryngoscope, 126:2475-2479, 2016.
