Surgical management for recurrent pharyngoesophageal (Zenker's) diverticulum

Recurrent pharyngoesophageal diverticulum is uncommon after a one-stage diverticulectomy. Among 888 operations at the Mayo Clinic, recurrence has been noted after only 32 (3.6%). The present report outlines our management during a 19-year period of 44 patients operated on previously, including management of various late complications seen in 13 patients after diverticulopexy and diverticulectomy performed at other institutions. The study then focuses on the results in 31 patients in whom reoperation for symptomatic recurrent diverticulum was performed at the Mayo Clinic during the same period. Although reoperation posed a technical challenge, there was only 1 operative death (3.2%). Surviving patients experienced highly satisfactory late results, with only two recurrences. Early surgical morbidity was considerably higher than for primary operations, but this did not interfere with most patients having excellent to good late results.
