Endoscopic diverticulotomy using Ligasure

Endoscopic treatment of Zenker diverticulum is considered feasible, effective and safe. The use of the Ligasure™ vessel sealer provides adequate and quick dissection of tissue, achieving effective haemostasis. Retrospective, descriptive study of all patients with Zenker diverticulum who were treated by endoscopic diverticulotomy using Ligasure™. The procedure was performed in the endoscopy unit under deep sedation controlled by the endoscopist. Patients were subsequently admitted for observation and, after discharge, were followed-up in the outpatient clinic. Eight patients, 5 women and 3 men, mean age 78±15 years, 25% ASA I, 36% ASA II, 14% ASA III and 25% ASA IV. Main symptom: dysphagia. Diverticula size: 1-7cm. Technical success: 100%. one patient with upper gastrointestinal bleeding. Average stay: 24h. Seven patients: asymptomatic; one patient with partial improvement, requiring repeat endoscopic intervention. Surgery and morbidity and mortality: 0%. The treatment of Zenker diverticulum by endoscopic diverticulotomy using the Ligasure™ vessel sealer is highly effective, fast and safe, and could be considered the treatment of choice.
