Introduction
Colonic diverticular bleeding is an increasingly common cause of lower gastrointestinal bleeding, particularly with aging populations. Although many cases resolve spontaneously, recurrent or severe bleeding often requires endoscopic intervention. Techniques such as endoscopic band ligation and over-the-scope clip have emerged as effective hemostatic options. While EBL is widely used and known for reducing rebleeding, OTSC is a newer modality with strong mechanical closure capabilities. However, direct comparative data between these techniques remain limited.
Problem Statement
There is insufficient evidence to determine whether OTSC or EBL provides superior outcomes in preventing rebleeding in colonic diverticular bleeding.
Summary
This propensity score–matched cohort study provides important comparative insights between OTSC and EBL in the management of CDB. Both techniques demonstrated similar effectiveness in achieving initial hemostasis, with no significant differences in need for transfusion, additional interventions, or adverse events.
However, OTSC showed a clear advantage in reducing early (30-day) rebleeding rates and was associated with a shorter hospital stay. This suggests that while both methods are equally effective for immediate bleeding control, OTSC may offer more durable hemostasis.
Clinically, these findings support considering OTSC as a preferred option in patients at high risk of rebleeding, particularly where long-term hemostatic durability is critical. Nevertheless, factors such as availability, expertise, and cost may influence real-world decision-making.

Introduction: Obesity has become one of the greatest global health challenges. New incretin-based therapies—including semaglutide, tirzepatide, resmetirom, and SGLT2 inhibitors such as empagliflozin—have transformed the treatment of obesity, diabetes, and MASLD. However, many patients discontinue...
