Abstract: A 75-year-old man was admitted with a 2-week history of melena. Despite conservative medical treatment, including proton pump inhibitor therapy, he had ongoing evidence of active gastrointestinal bleeding and was referred for emergency endoscopic hemostasis. Endoscopy identified a 2.0×2.0 cm ulcer on the lesser curvature of the gastric body ([ Fig. 1a ]). A red, adherent thrombotic plug with active oozing was observed at the center of the ulcer base, consistent with a high-risk stigmata lesion.[ 1 ] Initial hemostasis was achieved by thermal coagulation using hot biopsy forceps. Given the substantial risk of rebleeding, definitive mechanical closure and vessel control were pursued. Conventional through-the-scope clips may be limited by a relatively small opening angle and insufficient bite depth, which can hinder secure grasping of a broad, fibrotic ulcer base ([ Fig. 1b ]). Therefore, an anchor clip–assisted loop ligation technique was performed ([ Video 1 ]). Three hemoclips were deployed circumferentially along the ulcer margin to serve as anchor points ([ Fig. 1c ]). A nylon loop was then positioned around the anchors and progressively tightened, drawing the ulcer edges together to achieve complete defect closure and simultaneous mechanical ligation of the presumed culprit vessel ([ Fig.1d–f ]). Post-procedurally, the patient had no recurrent melena or signs of ongoing bleeding. He remained hemodynamically stable, required no further endoscopic intervention, and was discharged after clinical improvement.

( f ) Progressively tightened to approximate the ulcer margins, resulting in complete defect closure.
