AIM
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.
目的
探讨缺血在小肠狭窄发病机制中的作用。
方法
采用改良的斯帕尔托兹方法研究39例小肠狭窄的血管解剖结构。选取10个正常小肠段作为对照进行研究。
结果
71.8%的小肠狭窄显示肠系膜血管阻塞（p = 0.008）。对结核性狭窄的亚组分析显示，70.8%的狭窄存在肠系膜血管阻塞（p = 0.0098）。
结论
缺血在小肠狭窄的发病机制中起重要作用。肠系膜血管病变与肠道结核性狭窄有显著关联。
