This study and some of its methodological aspects deserve examination in light of society guidelines suggesting OTSC should be reserved for patients who have failed initial traditional endoscopic therapy.2

One hundred patients with a complete Rockall score ≥7 were randomised to OTSC or standard treatment (through-the-scope clips (TTSC) and epinephrine injection in 98%). The primary endpoint of haemostasis without recurrent bleeding for 7 days was achieved in 91.7% with OTSC versus 73.1% with TTSC (p=0.019).

Two previous fully published randomised trials assessing OTSC in non-variceal UGI bleeding have suggested its superiority to standard approaches in managing recurrent bleeding,3 or as …
