title: Long term follow-up of transcatheter coil embolotherapy for major colonic haemorrhage.
abstract: OBJECTIVE
  Therapeutic angiography with embolization is fast becoming the preferred treatment modality for major bleeding in the lower gastrointestinal (LGI) tract. The aim of this study was to determine the long term outcome and complications of percutaneous coil embolization (PCE) and its efficacy as definitive therapy in patients with major LGI bleeding.
  
  
  METHODS
  All patients presenting to our institution with a haemodynamically significant LGI tract bleed between 1995 and 2001 that were unresponsive to conservative measures were considered for emergency angiography and coil embolization where appropriate. The outcome of these individuals was determined by case note review and telephone interview.
  
  
  RESULTS
  There were 20 patients (11 females) with a mean follow-up period 72 months, mean age was 67 years. All underwent PCE following positive angiogram. The most common site of bleeding was the right colon (40%); haemostasis was successfully achieved in 16 (80%) patients. Five of the 20 patients died within 30 days of the intervention, three following PCE and two following surgery. None of the mortality following PCE was considered procedure related. On long term follow-up four patients required readmission to hospital for further LGI bleeds at 1, 2, 12 and 16 months respectively. Ischaemic complications occurred in 23%.
  
  
  CONCLUSIONS
  Superselective embolization as the primary technique for the treatment of haemodynamically significant LGI bleeding is an effective, feasible and safe technique. Long term follow-up in our series up to 72 months has shown that it should be considered as both a primary and potentially definitive treatment for life threatening LGI bleeds.
