| Popis: | Transarterial catheter embolization (TAE) is integral in the management of lower gastrointestinal bleeding (BLGIT). The efficacy of superselective embolization has reduced the need for emergent surgical resection as a treatment modality. Objective To determine the outcomes of TAE in the management of BLGIT in terms of efficacy rates, recurrent bleeding rates and long term results without the need for surgical intervention. Method Patients who underwent TAE for BLGIT between September 2000 and May 2006 were analysed. Data were extracted from the records for analysis. Results Sixty-eight patients with a mean age of 76 years and equal gender distribution were analysed. Sixty-nine per cent presented with haematochezia, 40% with malena. Sixty-three patients had a prior RBC scan performed, all of which were positive. Colonoscopy was attempted in 18 patients of which four managed to localize the bleeding site. Embolization was performed in these patients using mainly polyvinyl alcohol particles and/or microcoils. The morbidity rate was 21%, comprising mainly fever and nonspecific abdominal pain with only four ischaemic complications and one report of colonic infarction. Early recurrent bleeding occurred in six patients. Three were treated with repeat embolization and two required surgery. There were no mortalities. After a mean follow-up of 12 months, 12 (17.6%) patients developed further episodes of BLGIT, necessitating further intervention. Conclusion Transarterial catheter embolization is effective and safe in the acute management of BLGIT and reduces the need for further definitive surgery in a majority of patients. |
