Impaired blood flow

Impaired blood flow: Intestinal contents are blocked, and there is no impaired blood flow in the intestine. Intestinal obstruction is a group of clinical syndromes caused by the inability of the intestinal contents to run to the distal end due to various reasons, which is one of the common acute abdominal diseases in surgery. Clinically, it is often divided into mechanical intestinal obstruction, dynamic intestinal obstruction, and blood-borne intestinal obstruction according to its cause. In addition, it can be divided into simple and strangulated (ischemic) intestinal obstruction according to whether the obstruction is accompanied by intestinal blood flow disorder; according to the location of the obstruction, it is divided into high intestinal obstruction, low intestinal obstruction and colon obstruction; according to the degree of obstruction Partial (incomplete) and complete intestinal obstruction; according to the onset of acute onset into acute intestinal obstruction and chronic intestinal obstruction. Intestinal obstruction caused by pressure on both ends of the intestinal canal is called occlusive intestinal obstruction. Such intestinal obstruction has a marked increase in intestinal pressure, and the intestinal canal is highly swollen, which can cause intestinal wall blood flow disorders and cause intestinal necrosis and perforation.
