Endoscopic Septotomy Is Safe and Effective for the Treatment of Zenker’s Diverticulum

Prateek Sharma, MD, FASGE, reviewing Repici A, et al. Am J Gastroenterol 2021 Sep.

Zenker’s diverticulum (ZD) can lead to dysphagia to both solids and liquids and can be treated endoscopically or surgically. This retrospective, single-center, observational study evaluated the short- and long-term outcomes of patients treated with flexible endoscopic septotomy (FES).  

This study followed 256 patients (186 males; mean age, 74.3 ± 11.6 years) referred for endoscopic treatment of symptomatic ZD, for which FES was deemed first-line therapy. All of the procedures were performed by the same expert endoscopist. Follow-up included assessment by phone call or clinic visit at 1 month postprocedure, followed by every 6 months for 2 years and then yearly until study close or a recurrence. 

The procedure was successfully completed in all patients. The mean duration of the procedure was 18.5 ± 5.2 minutes, and deep sedation with propofol was the anesthesia method for 92.2% of patients. More than half of the patients (52.3%) were discharged following the procedure, and those who were admitted were hospitalized for 1.6 ± 1.1 days. Early clinical success, defined as resolution of symptoms 1 month postprocedure, occurred in 96.8% of patients (248/256). Eighty patients (31.3%) had symptom recurrence within 65.1 ± 33.9 months. FES was repeated in 95% of patients (76/80), 89.5% of whom had no symptoms within 37.3 ± 11.7 months from the repeat FES. 

The adverse event (AE) rate was low at 3.5% (9/256), with 1 minor AE (severe pharyngodynia), 3 moderate AEs (dysphagia requiring endoscopy and removal of clips, aspiration pneumonia, and postprocedure bleeding), and 5 severe AEs (perforation). No patient deaths were reported.

COMMENT

Endoscopic septotomy is safe and effective in the short term for the treatment of Zenker’s diverticulum. During long-term follow-up (5 years), 30% of patients can experience recurrence of disease, which can be successfully retreated by a flexible endoscopic approach. Patients with Zenker’s diverticulum who undergo endoscopic therapy should be informed that repeat FES may be required to ensure remission.
