Upper gastrointestinal bleeding is still an important clinical problem, even though about 80% of bleedings due to peptic lesions stop spontaneously. Starting from 1970, a lot of endoscopic hemostatic procedures has been developed and employed with good results, but, at present, the key problem is represented by the selection and management of the patients at highest risk of rebleeding. This work reviews both techniques and devices most commonly used, but at present none of them can be considered actually better than the other ones. According to the SIED (Società Italiana di Endoscopia Digestiva) guidelines, the techniques of choice should be cheap, effective, safe and easy to perform, the pivotal role in determining the success rate of endoscopic hemostasis being played by the endoscopist's experience.
