A 67-year-old patient with melena and symptoms of shock, along with additional clinical symptoms of fatigue and severe anemia (initial hemoglobin level 7.9 g/dL), was transferred to our intensive care unit. The patient had multiple comorbidities with chronic renal failure, cardiac decompensation, peripheral arterial occlusive disease, and chronic obstructive pulmonary disease. Additionally, he had had a recent arterial embolus and, for this reason, was anticoagulated with heparin. A gastroscopy was performed 3 days after the patient had started anticoagulation therapy, when he presented with clinical signs of gastrointestinal bleeding. A Forrest IIa ulcer was seen in the descending duodenum and, because of the anticoagulation, definitive hemostasis was needed, being achieved following application of an 11/3 traumatic over-the-scope clip (OTSC; Ovesco, Tübingen, Germany). The patient’s clinical course remained stable for the first 9 days. Unfortunately, on postoperative day 9, his physical condition progressively worsened with severe gastrointestinal bleeding, tachycardia, and hypotension, despite endoscopic intervention and transfusion of numerous red blood cell units (n =8). We decided to repeat a gastroscopy and found an active site of bleeding (Forrest Ib) under the OTSC, probably originating from the arteria gastroduodenalis. We assumed the OTSC had been wrongly positioned during the initial application with insufficient compression of the target vessel. Owing to our hypothesis of insufficient vessel compression, we decided to apply an endoloop (MAJ254; Olympus) under the OTSC in order to achieve sufficient compression of the vessel (▶Fig. 1; ▶Video 1). The further clinical course was uneventful and the patient rapidly recovered without restrictions. In keeping with the clinical picture, an endoscopic follow-up examination after 6 weeks showed persistent hemostasis with a healed ulcer. The OTSC and endoloop had both fallen off (▶Fig. 2). In conclusion, it has been shown that the OTSC is a safe hemostatic tool [1, 2]; however, our case shows that precise E-Videos
