Core Tip

Core Tip: The objective of our retrospective multicenter study was to evaluate the efficacy and safety of the over-the-scope-grasper, a new endoscopic grasping tool, originally designed for endoscopic pancreatic necrosectomy. A total of 56 procedures were evaluated, including 37 pancreatic necrosectomies with a technical success of 97%. In the other indications - removal of foreign bodies and blood clots or cleaning of insufficiency cavities before endoluminal vacuum therapy - the technical success rate was 100%. These first multicenter data show the over-the-scope-grasper as a promising tool for endoscopic pancreatic necrosectomy and beyond.
