Abstract

Background

The Over-the-scope clip (OTSC) has been recently introduced for multiple purposes, including refractory bleeding, perforation, fistula, and anastomotic dehiscence of the gastrointestinal tract. However, no easy access techniques for delivering OTSCs to distant sites have been described. Therefore, we have developed a simple and safe guidewire-assisted OTSC delivery (GOD) method for use on the distal intestine. This study aimed to investigate the technical feasibility and safety of the method.

Material and methods

Between June 2018 and April 2019, all eight patients who underwent the GOD method were retrospectively examined. The primary outcome was the successful rate of OTSC delivery to the lesion without complications. The secondary outcomes were GOD procedure time, total procedure time, technical and clinical OTSC success rates, and GOD- and OTSC-associated complications.

Results

The rate of successful OTSC delivery was 100%. The median procedure time of GOD was 21 min (range 8–29). The median total procedure time was 38.5 min (range 26–41). The technical and clinical success rates of OTSC were 100% and 75% (6/8), respectively. No GOD- or OTSC-associated complications occurred.

Conclusions

The GOD method is a feasible and safe technique for delivering OTSC toward the small and proximal large intestine.
