Utility of the “bear claw”, or over-the-scope clip (OTSC) system, to provide endoscopic hemostasis for bleeding posterior duodenal ulcers

Abstract

The "bear claw", or over-the-scope clip (OTSC) system (Ovesco Endoscopy, Tübingen, Germany), is an innovative clipping device made of superelastic biocompatible nitinol [1] [2] [3]. This device was developed to close wall defects of the luminal gastrointestinal tract, such as perforations, anastomotic leaks, and fistulas [1] [2]. The use of the "bear claw" in humans is still limited, but due to the excellent capabilities of the "bear claw" to close large mucosal defects, more reports on its efficacy are being published [2] [3]. Here we present the use of the "bear claw" to provide hemostasis of large ulcers of the posterior duodenal wall.
