Flexible endoscopic incisional therapy for Zenker's diverticulum (FEIT-Z) is an effective treatment for surgical failures or non-operative patients.

Abstract

BACKGROUND:

Symptomatic Zenker's diverticulum (ZD) occurs mostly in the elderly, who often have significant comorbidities, and poor neck hyperextension, putting them at high risk for surgical management while also increasing the potential of technical failure. Flexible endoscopic incisional therapy for Zenker's diverticulum (FEIT-Z) offers a safe approach to this problem with high technical and clinical success rates. There are limited data on its use following a failed surgical approach or in patients unfit for a surgical approach. The aim of this study was to assess clinical and technical outcomes of FEIT-Z in patients who were non-operative candidates or refused or failed surgical management.

METHODS:

Patients who underwent FEIT-Z from January 2015 to February 2019 at a tertiary referral center were included. Patient demographics, prior ZD surgical history, procedural data, dysphagia scores, clinical success, and adverse events (AE) were collected. Univariable analysis was performed to assess differences between pre- and post-FEIT-Z dysphagia scores.

RESULTS:

30 patients undergoing FEIT-Z were included. Seven had a prior failed ZD surgical approach, 6 refused surgical management, and 17 were deemed to be non-operative candidates based on medical comorbidities. Mean age was 78.4 (± 12.1) and 36.7% were male. Technical success of FEIT-Z was 96.7%. There was a significant improvement in dysphagia scores after FEIT-Z: 2.3 (± 0.64) vs. before, 0.4 (± 0.76) (p < 0.001). Long-term clinical success was achieved in 73.3% of patients. Adverse events were seen in 23.3% of patients; however, these were graded as mild in 85.7% of patients. One microperforation was managed with antibiotics.

CONCLUSION:

FEIT-Z is a safe procedure with low adverse events and a high rate of technical and clinical success. FEIT-Z can be done in patients who fail previous surgical treatment, refuse a surgical approach, or are not surgical candidates due to medical comorbidity or other factors.
