The newly designed over-the-scope clip (OTSC) seems to overcome several limitations of current clipping system, such as size and opening-closing force, allowing better control of gastric or colonic bleeding and/or deep wall defect or perforation.
The aim of this retrospective analysis was to describe the new endoscopic device and evaluate our first clinical experience.
We treated with the OTSC system 9 patients (range, 58-85 years; 6 men, 3 women) with bleeding and/or deep wall lesions of the GI tract. The OTSC system is composed of an application cap, which is mounted onto the distal tip of the endoscope and a connected releasing mechanism, installed on the handle of the scope. The rotation of the handle allows the release of the clip by a two tube sliding mechanism.
All applications resulted successful, i.e. haemostasis was achieved, and/or wall defects could be closed. No complication was observed that could be ascribed to the clip itself or to the technique.
The OTSC system is a new endoscopic tool for compression of large tissue areas and its indications are nonvaricose bleedings difficult to control and lesions or perforations of the GI tract. The initial clinical use of this clipping device proved to be efficient and effective.
新设计的内镜下套扎夹（OTSC）似乎克服了当前套扎系统的一些局限性，如尺寸和开合力，能更好地控制胃或结肠出血和/或深部壁缺损或穿孔。
本回顾性分析的目的是描述这种新型内镜设备并评估我们的首次临床经验。
我们使用OTSC系统治疗了9例胃肠道出血和/或深部壁病变患者（年龄范围58 - 85岁；6名男性，3名女性）。OTSC系统由一个安装在内镜远端的应用帽和一个安装在镜柄上的相连释放机构组成。通过手柄旋转，利用双管滑动机制释放夹子。
所有操作均成功，即实现了止血，和/或封闭了壁缺损。未观察到可归因于夹子本身或该技术的并发症。
OTSC系统是一种用于大面积组织压迫的新型内镜工具，其适应证为难治性非静脉曲张性出血以及胃肠道病变或穿孔。该套扎装置的初步临床应用证明是高效且有效的。
