title: [Colonic necrosis and stricture due to non-occlusive ischemic colitis. Report of two cases and review of the literature].
abstract: BACKGROUND
  Non-occlusive ischemic colitis appears to be a collection of diseases rather than a single entity. The presumed etiologies are numerous; however, it typically develops spontaneously in the absence of major vasculature occlusion. It includes a wide clinical spectrum ranging from mild to severe forms. Some patients may develop complications and management of this disorder depends on disease severity.
  
  
  OBJECTIVE
  Report of two cases and review of the literature.
  
  
  METHODS
  Two cases are described, both requiring surgery with primary anastomosis. One patient had colonic gangrene that required an open right colectomy and the other a totally laparoscopic left colectomy for a stricture.
  
  
  CONCLUSIONS
  Non-occlusive ischemic colitis is idiopathic. Some patients requiring surgery may be selected to undergo primary anastomosis and laparoscopic surgery.
