Endoscopic removal of over-the-scope clips using a novel cutting device: a retrospective case series

Background and study aims: Over-the-scope clips (OTSCs; Ovesco Endoscopy, Tübingen, Germany) are extensively used for treatment of gastrointestinal perforations, leakages, fistulas, and bleeding. In this report, a new method of removing OTSCs using a prototype bipolar cutting device is described.

Patients and methods: A total of 11 patients underwent endoscopic removal of an OTSC. The OTSC was cut at two opposing sites by a prototype device (DC ClipCutter; Ovesco Endoscopy). The remaining clip fragments were extracted using a standard forceps.

Results: Mean procedure time was 47 minutes (range 35 – 75 minutes). Cutting of the OTSC at two opposing sites was successful in all cases (100 %). Complete retrieval of all clip fragments was possible in 10 patients (91 %). The overall success rate for cutting and complete removal of the clip was 91 %. No major complications were observed.

Conclusions: Removal of OTSCs with the prototype device was feasible and effective. The device may be valuable for OTSC removal in emergency as well as elective indications.
