Efficacy of a Hemostatic Agent (PuraStat®) in Reducing Delayed Bleeding After Endoscopic Submucosal Dissection

France288 participantsStarted 2022-02-28

Plain-language summary

The problem of delayed bleeding after endoscopic resection is becoming important due to the growing number of indications for anti-aggregation or anticoagulant treatment for cardiovascular reasons in the aging populations. Previous studies have shown that in patients at high risk of bleeding, the use of (PuraStat®), a simple and easily applicable solution, decreases the rate of delayed bleeding by promoting wound healing. Various preventive treatments, such as the prophylactic use of clips, have been tried to prevent the occurrence of delayed bleeding, but to date, no treatment has clearly shown its effectiveness. In addition, preventive hemostasis with clips is difficult and costly. The main objective is to compare the efficacy of PuraStat® to the standard treatment in reducing delayed bleeding after colorectal ESD in patients at high risk of delayed bleeding. The secondary objectives are to compare the same two strategies in terms of effectiveness and side effects. The primary outcome measure is the percentage of delayed bleeding at 30 days after surgery (ESD).
