An 87-year-old man with a history of diverticular bleed and abdominal aortic stenting presented with 3 episodes of hematochezia. Colonoscopy identified multiple diverticula, including one that was actively bleeding in the sigmoid colon (Figure 1). Two resolution clips were placed in the bleeding diverticulum with hemostasis (Figure 2).

Twelve hours later, the patient had recurrent hematochezia. The previously placed aortic stent prevented cannulation of the inferior mesenteric artery by interventional radiology, so a repeat partial colonoscopy was performed without preparation, revealing fresh blood surrounding the 2 previously placed clips. An upper endoscope (Olympus 190 HQ; Olympus, Center Valley, PA) was fitted with a 13.6-mm over-the-scope clip (OTSC®; Ovesco, Tübingen, Germany) that was deployed over the diverticulum and the previously placed clips (Figure 3). The bleeding stopped immediately. The patient did not require surgery and was discharged the next day; he was followed over period of 4 months after discharge and had no further bleeding.

Diverticular bleed is the most common reason for lower gastrointestinal bleeding, particularly in older patients. Colonoscopy is considered to be the first-line diagnostic and therapeutic approach, with endoscopic clips generally effective at achieving hemostasis. Rebleeding is common and presents a clinical challenge. In such cases, radiological embolization and surgery are the next interventions; however, they are not without complications.1 The OTSC is a new device designed for mechanical compression and tissue approximation that has been used for complicated GI bleeding, management of perforations and fistulae, full-thickness resection of tumors, and stent anchoring.2 In addition, OTSC has been shown to be an effective method of endoscopic hemostasis for major gastrointestinal bleeding.3 Complications have been reported, including tongue injury as a result of accidental clip deployment in the mouth.4 The use of the OTSC allowed us to achieve hemostasis in our patient without the need for surgery or embolization.
