ObjectiveTo prospectively analyze quality‐of‐life outcomes following transoral diverticulotomy with cricopharyngeal myotomy (DCPM) for Zenker’s diverticulum (ZD).Study DesignProspective single‐group study.SettingsTertiary academic institution.Subjects and MethodsA prospective multicenter study performed from January 1, 2012, to July 1, 2014, included 18 patients presenting with ZD undergoing DCPM. Standardized questionnaires—including the 10‐item Eating Assessment Tool (EAT‐10), Functional Outcome of Swallowing Scale (FOSS), and the Reflux Symptom Index (RSI)—were completed preoperatively and at 3 and 6 months postoperatively. Videofluoroscopic studies were obtained and analyzed by our senior speech‐language pathologist, who was blinded to the clinical outcomes.ResultsEighteen patients were included (11 women; mean age, 72.6 years; range, 53‐86 years). All patients had ZD on preoperative videofluoroscopic swallowing studies. The most common comorbidities included hypertension (10 of 18, 55.6%), dyslipidemia (8 of 18, 44.4%), hiatal hernia (6 of 18, 33.3%), and gastroesophageal reflux disease (5 of 18, 27.8%). Median preoperative RSI was 27 (interquartile range [IQR], 22.5‐31.5); FOSS, 2 (IQR, 2‐3); and EAT‐10, 21.5 (IQR, 13.5‐27.5). The 3‐month questionnaire (88.9% completion) demonstrated an improved median RSI of 5 (IQR, 1‐7.5; P <. 001), FOSS of 0 (IQR, 0; P <. 001), and EAT‐10 of 0 (IQR, 0‐3; P <. 001). Fourteen patients (77.8%) completed the 6‐month questionnaire, demonstrating a median RSI of 4 (IQR, 0‐8), FOSS of 0 (IQR, 0‐0.5), and EAT‐10 of 1 (IQR, 0‐3). While regurgitation decreased following surgery (P =. 007), nighttime cough did not (P =. 25).ConclusionThis study supports an improvement in functional outcome and quality of life in patients with ZD undergoing DCPM.
