Background and aims: the stag-beetle knife is a new scissor-like endoscopic device that can be used for the treatment of Zenker’s diverticulum, although experience is limited. The aim of this study was to evaluate the efficacy and safety of the SB Knife™ for the endoscopic treatment of Zenker’s diverticulum. Methods: a single-center prospective study of 16 patients was performed between May 2017 and April 2019. The rate of complications and symptom changes was evaluated. Results: the median age was 78 years and 62.5% of the patients were male. All had dysphagia, 43.8% choking, 31.3% regurgitation and 6.3% respiratory symptoms. The median size of the diverticulum was 20 mm and the median follow-up was 281 days. There were no intra-procedure complications and only one major post-procedure complication was reported that was a microperforation. All patients had clinical improvement. Two patients had relapsing symptoms and were successfully treated with the same method. Conclusions: the SB Knife™ seems to be a safe and effective technique for the treatment of Zenker’s diverticulum.
