title: Vascular anatomy of strictured small bowel.
abstract: OBJECTIVE
  To investigate the role of ischemia in the pathogenesis of small bowel strictures.
  
  
  METHODS
  Vascular anatomy of 39 small bowel strictures was studied using modified Spalteholtz method. Ten normal small bowel segments were studied as controls.
  
  
  RESULTS
  71.8% of small bowel strictures showed block in the mesenteric vessels (p=0.008). Subset analysis of tuberculous strictures showed block in the mesenteric vessels in 70.8% of strictures (p=0.0098).
  
  
  CONCLUSIONS
  Ischemia plays a significant role in the pathogenesis of small bowel strictures. Mesenteric vasculopathy has a significant association with tuberculous strictures of the intestine.
