Abstract

Background

Endoscopic clips vary in their designs and costs. Clip wastage is a common problem, and this is dependent on the success of its deployment.

Aims

The aim of this study is to compare the rates of successful deployment between two different commonly used endoscopic clips.

Methods

A single-center, retrospective study was conducted. Endoscopy reports of patients with clips deployed over 24 months were reviewed. We compared a long-pronged, reopening endoscopic clip (type A: Resolution clip; Boston Scientific, Natick, MA, USA) versus a short-pronged, single-opening clip (type B: QuickClip2; Olympus Medical Systems Corp, Japan). The main outcome was clip deployment success rate. Secondary outcomes were predictors of successful deployment, cost, and wastage.

Results

Of 14,690 endoscopic cases, 472 clips (171 type A and 301 type B) were deployed in 262 procedures. Type A clips had a significantly higher successful deployment rate (147/171, 86.0 %) than type B clips (221/301, 73.4 %) (p = 0.002). On multivariate analysis, variables independently associated with successful deployment included using type A clips (OR 2.07, 95 % CI 1.20–3.55; p = 0.009) and clips placed in the lower gastrointestinal tract (OR 3.48, 95 % CI 1.64–7.40; p = 0.001). The cost of using type A clips was higher than type B clips (p < 0.001). Type B clips were associated with more wastage (p = 0.049).

Conclusions

Long-pronged, reopening clips (type A) have a better deployment rate than short-pronged, single-opening clips (type B). Although type A clips had less wastage, the cost per procedure was higher.
