To investigate the clinical efficacy of interventional embolization treatment for nonvariceal gastrointestinal hemorrhage after failed endoscopic treatment.

From January 2011 to July 2020, 109 patients with nonvariceal gastrointestinal bleeding after failed endoscopic hemostasis treatment were treated with angiography and endovascular interventional treatment in our department. For patients with positive angiography, embolization of diseased arteries was performed. For negative patients with no signs of hemorrhage on angiography, empirical embolization was performed according to the hemorrhage site confirmed by endoscopy.

109 interventional angiographies were performed on 109 patients. Interventional embolization was performed in 45 patients who had definite bleeding sign on angiogram. 64 patients had no bleeding sign were performed empirical embolization. The technical success rate of embolization and empirical embolization was 100%. The rate of recurrent hemorrhage within 30 days was 27.52% (30/109), The late rehaemorrhagia rate was 1.83% (2/109). The total effective rate was 72.47%, including 66.67% (30/45) for therapeutic embolization and 74.14% (43/58) for empirical / prophylactic embolization. There were no significant differences in technical success rate, clinical success rate, short-term and long-term bleeding recurrence rate between the two groups. No serious complications were observed in our data.

Transcatheter arterial embolization is safe and effective for nonvariceal gastrointestinal hemorrhage after failed endoscopic treatment, and preoperative endoscopy has important guiding significance for interventional therapy.
