Clinical Trial 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).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of delayed bleeding after surgery (ESD)	Percentage of delayed bleeding is expressed primarily by the number of patients with at least one unplanned colorectal endoscopy occurring within 30 days of surgery (ESD)	through study completion, an average of 2 year
Secondary	Rate of emergency endoscopy use by risk factors for secondary bleeding	Number of patients with at least one unplanned colorectal endoscopy by factors for secondary bleeding occurring within 30 days of ESD.	through study completion, an average of 2 year
Secondary	Rate of emergency endoscopic hemostasis use by risk factors for secondary bleeding	Number of patients requiring hemostasis, unplanned occurring within 30 days of ESD.	through study completion, an average of 2 year
Secondary	Rate of cases requiring transfusion related to post-ESD bleeding	Number of patients for whom at least one transfusion was ordered after the ESD	through study completion, an average of 2 year
Secondary	Rate of adverse events related to procedures (delayed perforation and stenosis) in each of the 2 arms	Number of patients with at least one delayed perforation or one symptomatic stenosis.	through study completion, an average of 2 year
Secondary	Rate and duration of hospitalizations	Number of hospitalizations and number of days of hospitalization per stay within 30 days after ESD	through study completion, an average of 2 year
Secondary	Tolerance of PuraStat	Number of patients with at least one irritation or thromboembolic accidents.	through study completion, an average of 2 year
Secondary	Evaluation of the gel application time on the resection area	Time between introduction and removal of the PuraStat® catheter.	During the intervention
