Ischemic colitis or proctitis shows three evolutionary stages. a. complete recovery, b. fibrous stenosis, and c. acute ischemia leading to gangrene. The two first stages result more frequently from hemodynamic disorders than from vascular occlusions because, in the presence of the latter, collateral circulation develops. In addition, the colonic ischemia occurs in a septic medium in the presence of an abundant microbial flora which may be highly pathogenic.
缺血性结肠炎或直肠炎呈现三个演变阶段。a. 完全恢复,b. 纤维性狭窄,以及c. 导致坏疽的急性缺血。前两个阶段更多是由血液动力学紊乱而非血管闭塞引起,因为在血管闭塞的情况下会形成侧支循环。此外,结肠缺血发生在存在大量微生物菌群的感染性介质中,这些菌群可能具有高度致病性。
