Over-the-scope clip vs epinephrine with clip for first-line hemostasis in non-variceal upper gastrointestinal bleeding: a propensity score match analysis

摘要

The over-the-scope clip (OTSC) is a novel tool used to improve the maintenance of hemostasis for non-variceal upper gastrointestinal bleeding (NVUGIB); however, studies on the comparison with “conventional” techniques are lacking. In this study, we aimed to compare first-line endoscopic hemostasis achieved using conventional techniques with that achieved using OTSC placement for NVUGIB.
