title: Clinical characteristics of acute hemorrhagic rectal ulcer.
abstract: BACKGROUND
  Acute hemorrhagic rectal ulcer (AHRU) occurs suddenly with painless, massive, fresh rectal bleeding in elderly, bed-ridden patients who have a serious primary disease. There have been several reports on AHRU in Japan, but in Western countries, there have been none. We examined the clinical characteristics of four cases, and we report on AHRU in Western countries.
  
  
  METHODS
  The medical records and endoscopic findings in four patients with AHRU seen during a 3-year period were reviewed. The diagnosis of AHRU was established by clinical symptoms, endoscopic examination, and other methods.
  
  
  RESULTS
  All of the patients were elderly and bed-ridden and all had sudden onset of massive, fresh rectal bleeding without pain. Sigmoidoscopic examination of all patients showed a shallow or irregular bleeding ulcer in the lower rectum. In three cases, the clinical course was uneventful. In the other case, massive, fresh rectal bleeding recurred but transanal ligation was effective.
  
  
  CONCLUSIONS
  When painless, massive, fresh rectal bleeding occurs in elderly and bed-ridden patients, it is important to carefully examine the lower rectum, as there is a strong possibility of AHRU.
