Blood flow disorder
Introduction
Introduction Blood supply disorder: the intestinal content is blocked, and the intestinal tube has no blood supply disorder. A group of clinical syndromes, called intestinal obstruction, caused by various reasons that the intestinal contents cannot run smoothly to the distal end, is one of the common acute abdomen in surgery. Clinically, it is often divided into mechanical intestinal obstruction, dynamic intestinal obstruction and blood transport intestinal obstruction according to the cause of the disease. In addition, according to whether the obstruction is accompanied by intestinal blood supply disorders are divided into simple and strangulated (ischemic) intestinal obstruction; according to the obstruction site is divided into high intestinal obstruction, low intestinal obstruction and colonic obstruction; according to the degree of obstruction Partial (incomplete) and complete intestinal obstruction; according to the rapid onset of acute intestinal obstruction and chronic intestinal obstruction. If the intestinal obstruction caused by compression of both ends of the intestine is called closed intestinal obstruction, such intestinal obstruction has obvious pressure in the intestinal lumen, and the intestinal tube is highly swelled, which may easily cause intestinal blood supply disorder, leading to perforation of intestinal necrosis.
Cause
Cause
Causes of blood circulation disorders
Due to mesenteric vascular embolization or thrombosis, the intestinal wall blood supply disorder, followed by intestinal paralysis, resulting in intestinal narrowing necrosis caused by intestinal contents can not function properly.

Examination and diagnosis of blood circulation disorders
Clinical symptoms:
1. abdominal pain, paroxysmal cramps;
2. Vomiting, early reflex; late vomiting, high obstruction and vomiting early, low vomiting;
3. bloating, generally high is not obvious; low or paralytic is significant and wide;
4. The anus stops defecation and venting, and there may still be venting in the early stage of high position or obstruction.
5. Visible intestinal type and peristaltic wave, bowel sounds are accompanied by gas and water, peritonitis, tenderness and rebound tenderness are manifestations of intestinal strangulation.
Diagnose based on:
1. Paroxysmal abdominal cramps are manifestations of early or incomplete obstruction; and persistent paroxysmal aggravation of persistent abdominal pain is an early feature of strangulated obstruction. Severe persistent abdominal pain is a late manifestation of obstruction and can present with shock symptoms;
2. Early frequent vomiting is mostly high obstruction, and vomiting is more common after low abdominal distension;
3. Stop anal exhaust and defecation;
4. Abdominal distension with intestinal type, peristaltic wave, bowel sounds and gas over water;
5. Limited or extensive abdominal tenderness, rebound tenderness or hemorrhagic abdominal fluid for intestinal narrowing or perforation, peritonitis;
6. The abdominal plain film shows obvious dilatation of the intestine and gas-liquid surface;
7. Obvious or severe systemic dehydration with electrolyte and acid-base balance disorders.

Symptoms of confusing blood circulation disorder
Closed intestinal obstruction refers to the simultaneous obstruction of both ends of the small intestine and the mesenteric vessels, so that the intestinal obstruction is accompanied by obstructive intestinal tube (ie, closed hernia).
Low intestinal obstruction is a clinical manifestation of intestinal obstruction. Intestinal obstruction (ileus) refers to the intestinal contents being blocked in the intestine.
Aphid intestinal obstruction is caused by the mechanical blockage of the intestinal tract caused by agglomeration of aphids. It is the first in non-neoplastic occlusive intestinal obstruction, mostly simple and partial intestinal obstruction.
Clinical symptoms:
1. abdominal pain, paroxysmal cramps;
2. Vomiting, early reflex; late vomiting, high obstruction and vomiting early, low vomiting;
3. bloating, generally high is not obvious; low or paralytic is significant and wide;
4. The anus stops defecation and venting, and there may still be venting in the early stage of high position or obstruction.
5. Visible intestinal type and peristaltic wave, bowel sounds are accompanied by gas and water, peritonitis, tenderness and rebound tenderness are manifestations of intestinal strangulation.
Diagnose based on:
1. Paroxysmal abdominal cramps are manifestations of early or incomplete obstruction; and persistent paroxysmal aggravation of persistent abdominal pain is an early feature of strangulated obstruction.

5. Limited or extensive abdominal tenderness, rebound tenderness or hemorrhagic abdominal fluid for intestinal narrowing or perforation, peritonitis;
6. The abdominal plain film shows obvious dilatation of the intestine and gas-liquid surface;
7. Obvious or severe systemic dehydration with electrolyte and acid-base balance disorders.
