N2 - Background and Aim Flexible endoscopic septum division is becoming a prominent treatment option for Zenker's diverticulum (ZD). Over the years, various techniques have been developed and many cutting tools have been tested with varying results. We report our experience with a recently designed, monopolar, rotating, scissor-shaped device (SB Knife). Methods Data on 31 consecutive patients that underwent flexible endoscopic treatment for ZD with the use of the SB Knife were retrieved. Dysphagia, regurgitation, and respiratory symptom severity before the procedure were graded. Procedure duration, rate of complications, symptom changes after the procedure and rate of relapsing patients during follow up were recorded. Results The procedure was carried out successfully in all patients. Median procedure time was 14 min. One case of late-onset bleeding developed 1 week after the procedure, and was managed endoscopically. A significant symptom improvement was achieved (dysphagia: median score 0, P <0.001; regurgitation: median score 0, P <0.001; respiratory symptoms: median score 0, P = 0.009). Two patients had mild relapsing symptoms, respectively, after 4 and 9 months from the procedure but refused further treatment. Conclusions Endoscopic treatment of ZD using this new device is safe and efficient at short term follow up. No perforations were observed and there was a substantial reduction of symptoms after the treatment. Larger studies are needed to fully assess advantages of this new device for endoscopic treatment of ZD.
