A 61-year-old man was admitted because of colonic diverticular bleeding. Despite having achieved hemostasis at the cecum using five clips on the second day of admission, he re-bled on the third day, so we again performed a colonoscopy. During this colonoscopy, we removed the previously placed clips and, after placing a 0.035-inch biliary guidewire and withdrawing the colonoscope ([Fig. 1]), we attached an over-the-scope (OTS) clip (Ovesco Endoscopy AG, Tübingen, Germany) to the tip of the scope. We then re-inserted it into the cecum following the guidewire. Hemostasis was achieved using the OTS clip ([Fig. 2]; [Video 1]). The patient’s condition improved after this intervention, and he was discharged from hospital on the ninth day of admission.

Quality:

OTS clips have been used for gastrointestinal bleeding, perforations, and fistulas, full-thickness resection of tumors, stent anchoring, and to achieve hemostasis in cases of colonic diverticular bleeding [1] [2] [3]. In our case, we successfully used an OTS clip to stop diverticular bleeding after hemostasis by clipping had failed. One shortfall of OTS clips is that they restrict the endoscopic view when attached to the tip of the scope. To overcome this disadvantage, we used a guidewire inserted through the forceps hole at the tip of the scope, before its withdrawal. We withdrew the scope carefully and simultaneously ensured that the guidewire remained in the ascending colon using radiographic imaging. After withdrawing the scope, we attached the OTS clip and re-inserted the scope into the ascending colon following the guidewire, subsequently achieving hemostasis. In this manner, a scope with an OTS clip attached to it can quickly be advanced into the proximal colon, even in patients with heavy bleeding, as in this case.

This method might also be helpful to achieve hemostasis with endoscopic band ligation for diverticular bleeding [4], which also requires a dedicated attachment.
