Abstract

The effect of chronic progressive distal large bowel obstruction on intestinal blood flow was studied in 12 mini-pigs. Blood flow was measured by the techniques of xenon133 clearance and intracardiac injections of radiolabelled microspheres. Intestinal blood flow was increased in the left colon and ileum but decreased in the caecum. Blood was shunted from the mucosa to the muscle layers. The results suggest that primary anastomosis of the obstructed left colon is not contraindicated by haemodynamic considerations.

摘要

在12只小型猪身上研究了慢性进行性远端大肠梗阻对肠道血流的影响。采用氙133清除技术和心内注射放射性微球的方法测量血流。左结肠和回肠的肠道血流增加，但盲肠的血流减少。血液从黏膜分流至肌层。结果表明，从血流动力学角度考虑，梗阻的左结肠一期吻合并无禁忌。
