  • Dysphagia Characteristics in Zenker's Diverticulum OTOLARYNGOLOGY-HEAD AND NECK SURGERY Bergeron, J. L., Long, J. L., Chhetri, D. K. 2013; 148 (2): 223-228


    To evaluate dysphagia characteristics in patients with Zenker's diverticulum (ZD).Case series with chart review.Outpatient tertiary care dysphagia clinic.All ZD cases surgically treated over a 6-year period were identified and reviewed for dysphagia history and dysphagia characteristics on initial presentation using fiber-optic endoscopic evaluation of swallowing (FEES). Dysphagia symptoms and swallowing abnormalities were compared across groups based on diverticulum size (small <1 cm, medium 1-3 cm, and large >3 cm).Forty-six patients underwent a total of 52 procedures during the study period. ZD size was available in 49 cases (6 small, 26 medium, 17 large). Regurgitation symptoms were less frequent in patients with small (17%) compared with medium (68%) or large diverticula (76%; P = .03). Postswallow hypopharyngeal reflux (PSHR) was less frequent in patients with small (17%) compared with medium (91%) and large diverticula (87%; P < .01). PSHR was present on all FEES available for patients who presented with a recurrent or residual ZD (n = 7). In all cases, PSHR resolved after successful treatment of ZD. Pharyngeal residue indicating possible weakness was present in 24% of all patients at initial presentation.Preoperative assessment of dysphagia characteristics in ZD patients reveals that PSHR is predictive of a ZD larger than 1 cm and may be useful in surgical planning. PSHR is also helpful in identifying patients with recurrent or residual symptomatic ZD following surgical treatment. Pharyngeal weakness is present in a subset of ZD patients.
