Over-the-scope clip

Abstract

The endoscopic clips were first described by Hayashi in Japan in 1975. Since then, many different types of clips have been introduced to the gastroenterology practice. Over-the-scope clip (OTSC) or the “beer claw” was introduced in the year 2010. It works on the principle of dynamic compression and is applied over the scope like a band ligator. OTSC is a new endoscopic modality which can be used in acute gastrointestinal hemorrhage, iatrogenic perforation, anastomotic leak, and chronic fistula treatment with fairly good success rate and therefore, is now being considered as an alternative to surgery, especially in situations where surgery is not feasible.
