Surgical Techniques for Zenker's Diverticulum: A Comparative Analysis.

OBJECTIVE: To compare the different modalities for treatment of Zenker's diverticulum and the associated clinical outcomes. STUDY
DESIGN: Case series with chart review.
SETTING: Tertiary care hospital. SUBJECTS AND METHODS: Between 1995 and 2011, 164 patients underwent surgery for Zenker's diverticulum (stapler, n = 69; laser, n = 68; open, n = 27). Patient sociodemographics, medical comorbidities, pre- and postoperative subjective dysphagia and regurgitation score, complications, length of stay, time to oral intake, and recurrence were reviewed for each surgical modality.
RESULTS: No statistically significant difference in diverticulum prevalence was associated with age, gender, or treatment group. Mean length of hospital stay was not significantly different between the 3 groups (P = .14). A significant difference in time to oral intake was observed in the laser group compared with the other 2 groups (P = .012). No significant difference in recurrence (P = .21) or complication (P = .12) rates was identified between the 3 groups. Although all 3 groups demonstrated a significant decrease between preoperative and postoperative dysphagia and regurgitation scores, the degree of improvement was not significant when the 3 groups were compared.
CONCLUSION: There is no single "best" approach to Zenker's diverticulum. The open, laser, and stapler methods are equally effective and have similar complication rates. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.
