Zenker's diverticulum in the elderly: is operation justified?

BACKGROUND: Surgical correction of symptomatic Zenker's diverticulum is effective; however, elderly symptomatic patients may be denied surgical intervention because of perceived increased risks.

METHODS: To address this concern, we reviewed 75 patients (46 men and 29 women) found to have this condition during the past two decades.

RESULTS: Median age was 79 years (range, 75 to 91 years). Preoperative symptoms included dysphagia in 69 patients (92%), regurgitation in 61 (81%), pneumonia in 9 (12%), halitosis in 3 (4%), and weight loss in 1 (1%). Gastroesophageal reflux symptoms were noted in 27 patients (36%). Diagnosis was made by barium swallow in 63 patients, esophagoscopy in 5, and a combination of both in 7. Surgical procedures included both diverticulectomy and myotomy in 57 patients (76%), myotomy alone in 9 (12%), diverticulopexy and myotomy in 5 (7%), and diverticulectomy alone in 4 (5%). There was no in-hospital mortality. Complications occurred in 8 patients (11%) and included esophagocutaneous fistula in 4, pneumonia and urinary tract infection in 1, and wound infection, myocardial infarction, and persistent diverticulum in 1 each. Follow-up was available in 72 patients (96%) and ranged from 8 days to 17 years (median, 3.3 years). At follow-up, 64 patients (88%) were asymptomatic and 4 (6%) were improved with minimal symptoms. The remaining 4 patients (6%) have had varying degrees of dysphagia and all have been treated with periodic esophageal dilations.

CONCLUSIONS: Operation for symptomatic Zenker's diverticulum in the elderly is safe and effective and will result in resolution of symptoms and improved quality of life in most patients.
