Delayed post polypectomy bleeding. Risk factors associated with the presence of high-risk stigmata on the polypectomy site. Is expectant management possible?

This article, published in the journal Endoscopy, explores the risk factors associated with delayed post polypectomy bleeding, which is a common complication of endoscopic polypectomy. The study suggests that endoscopic hemostasis is usually not necessary for low-risk stigmata, such as flat pigmented stigma or a clean base. However, for high-risk stigmata, such as active bleeding or visible vessels, endoscopic hemostasis may be warranted. The study also highlights potential risk factors for high-risk stigmata, including hemodynamic instability, the need for transfusion, shock index, polyp size, and the use of prophylactic hemostatic clips. The authors conclude that further research is needed to determine which patients with delayed post polypectomy bleeding can be treated conservatively. [Extracted from the article]
