Core Tip

Core tip: In the present study, the over-the-scope clip (OTSC) was evaluated for first-line and second-line endoscopic treatment (FLET, SLET) of high-risk upper and lower gastrointestinal bleeding. One hundred OTSCs were applied in 93 patients. Primary hemostasis and clinical success was achieved in 88% and 78%, respectively. Statistical analysis shows no significant influence of anticoagulants on the rebleeding rate. The total mortality was 21.5%. Primary failure was significantly reduced by the use of OTSC as FLET (4.9% vs 23.1%, P = 0.008). This largest single-center data of OTSC-placement in high-risk GI bleeding published to date shows, for the first time, that FLET is a significant predictor of reduced rebleeding (OR = 5.2; P = 0.009).
