Surgical management of recurrent Zenker's diverticulum: A multi-institutional cohort study.

OBJECTIVE

This study identifies how recurrent Zenker's diverticula are treated.

METHODS

A retrospective chart review was performed from four tertiary referral academic voice and swallowing centers to identify individuals who underwent surgery for recurrent Zenker's diverticulum. Demographic data, surgical modalities for primary and revision surgery, symptoms pre and post revision and complications were recorded.

RESULTS

56 individuals met inclusion criteria. Primary surgery was open in 30.3% (n = 17) and endoscopic in 69.6% (n = 39). Revision surgery was performed via an open approach in 37.5% of cases (N = 21) and via an endoscopic approach in 62.5% of cases (N = 35). Revision surgical technique was based on pouch size, patient age and comorbidities, as well as patient and surgeon preference. There were no major complications and few minor complications.

CONCLUSION

Zenker's diverticulum symptoms can recur regardless of primary treatment modality. Both endoscopic and open approaches can safely treat recurrent Zenker's diverticula.
