Brief 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).

Design outcomes

Primary

MeasureTime frameDescription
Percentage of delayed bleeding after surgery (ESD)through study completion, an average of 2 yearPercentage 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)

Secondary

MeasureTime frameDescription
Rate of emergency endoscopy use by risk factors for secondary bleedingthrough study completion, an average of 2 yearNumber of patients with at least one unplanned colorectal endoscopy by factors for secondary bleeding occurring within 30 days of ESD.
Rate of emergency endoscopic hemostasis use by risk factors for secondary bleedingthrough study completion, an average of 2 yearNumber of patients requiring hemostasis, unplanned occurring within 30 days of ESD.
Rate of cases requiring transfusion related to post-ESD bleedingthrough study completion, an average of 2 yearNumber of patients for whom at least one transfusion was ordered after the ESD
Rate of adverse events related to procedures (delayed perforation and stenosis) in each of the 2 armsthrough study completion, an average of 2 yearNumber of patients with at least one delayed perforation or one symptomatic stenosis.
Rate and duration of hospitalizationsthrough study completion, an average of 2 yearNumber of hospitalizations and number of days of hospitalization per stay within 30 days after ESD
Tolerance of PuraStatthrough study completion, an average of 2 yearNumber of patients with at least one irritation or thromboembolic accidents.
Evaluation of the gel application time on the resection areaDuring the interventionTime between introduction and removal of the PuraStat® catheter.
