Despite the recent advances in endoscopic hemostatic techniques, the management of lower gastrointestinal bleeding could be sometimes challenging. Hemostatic powders such as Hemospray, EndoClot, and Ankaferd Blood Stopper have found their way into digestive endoscopy and are licenced in many countries especially for use in upper gastrointestinal bleeding. We reviewed the literature on the use of these hemostatic powders in different situations in lower gastrointestinal bleeding and looked at the success rate and rebleeding rate. Most of the data are derived from case reports, retrospective and prospective case series with absence of any randomized controlled trials. Hemostatic powders were used as primary or salvage therapy to control bleeding from polypectomy site, colonic tumors, diverticula, arteriovenous malformations, radiation proctitis, ischemic colitis, and surgical intestinal anastomosis. The rate of immediate control of bleeding is in the range of 88–100% with a recurrence rate of 3–13% except for radiation proctitis bleeding where rebleeding rate can be as high as 77%. Although there are many advantages for the use of local hemostatic agents in lower gastrointestinal bleeding, future randomized controlled trials comparing them with conventional methods are needed.
