Core Tip

Core Tip: Transarterial embolization enables the clinician to control gastrointestinal bleeding with high rates of technical and clinical success. We still do not know when the clinician should conclude endoscopic procedures to control gastrointestinal bleeding. This retrospective study compared patients with conservative treatment and patients who underwent catheter angiography. Patients in the catheter angiography group had a higher shock index, a higher Glasgow-Blatchford score and more rarely achieved hemostasis in primary endoscopy. These patients needed more transfusions, had longer hospital stays and had to undergo subsequent surgery more frequently. Endoscopic hemostasis proved to be the crucial difference between the two patient groups.
