ABSTRACT
AIM:
To evaluate the technical feasibility, success of hemostasis and complications of transcatheter embolization in the treatment of acute lower gastrointestinal (GI) bleeding.METHODS:
Retrospective review of 63 patients with acute lower GI bleed who had undergone transcatheter selective embolization of mesenteric arteries over a two-year period. Embolization was carried out only if the arteria recta leading to the bleed could be successfully catheterized (n=52). The lesions treated were located in the jejunum (n=13), ileum and ileo-cecal region (n=9), appendicular region (n=2) and colon (n=28). Embolization was performed with only polyvinyl alcohol particles (PVA) (250-500 microns) in 23 patients, only microcoils in 16 patients and both PVA particles and microcoils in 13 patients. Twenty-eight patients were evaluated for objective evidence of ischemia by colonoscopy (n=21) and/or histologic evidence in the surgical specimen (n=7); 23 patients were followed up clinically.RESULTS:
Immediate hemostasis was achieved in 61 of 63 patients; of the remaining 2 patients, one underwent surgery whereas the other died during the procedure. Recurrent bleeding occurred in 9 patients - 6 were managed surgically and 3 medically. Endoscopic evaluation showed mucosal ischemia in 7 patients but they remained asymptomatic on follow up. Embolization was the sole modality of treatment in 41 patients (78.9%).CONCLUSION:
Transcatheter superselective embolization is an effective and safe modality of treatment for acute lower GI bleeding.
