Multicenter evaluation of first-line endoscopic treatment with the OTSC in acute non-variceal upper gastrointestinal bleeding and comparison with the Rockall cohort: the FLETRock study

Introduction The over-the-scope clip (OTSC) overcomes limitations of standard clips and achieves a more efficient and reliable hemostasis in non-variceal upper gastrointestinal bleeding (NVUGIB). The study aims to evaluate mortality, rebleeding, and mortality after rebleeding of patients in whom the OTSC was used as the first-line endoscopic treatment (FLET) of NVUGIB.
