What is strangulating intestinal obstruction

What is strangulating intestinal obstruction?

1. Strangulated intestinal obstruction strangulated intestinal obstruction refers to the obstruction of intestinal contents due to mesenteric vascular pressure, thrombosis or embolism. For common acute abdomen, it can be caused by a variety of factors. At the beginning of the disease, the obstructed intestinal segment first undergoes anatomical and functional changes, followed by loss of body fluids and electrolytes, intestinal wall circulation disorders, necrosis and secondary infection, and eventually leads to sepsis, shock and death. Of course, if it can be diagnosed in time and treated actively, most of them can reverse the development of the disease and thus be cured.

2. Strangulating ileus is the most serious of the strangulating ileus. It occurs suddenly, with severe abdominal pain forming paroxysmal colic, accompanied by nausea and vomiting. Patients who do not pass gas consciously have obvious abdominal distension, peristaltic waves and the sound of gas passing through water. They will soon develop obvious symptoms of dehydration and continue to experience toxic shock. Doctors can see peristaltic waves of the abdominal wall and hear the sound of gas passing through water. The X-ray abdomen is flat, and very dark blood can be sucked out by abdominal dressing. Clinical characteristics: acute onset, obvious abdominal symptoms, early dehydration and poisoning shock, and high mortality rate if rescue is not timely.

3. Due to the accumulation and expansion of gas and liquid, the intestinal wall becomes thinner, and intestinal pressure can cause intestinal wall blood circulation disorders to a certain extent. The initial manifestations are venous reflux obstruction, congestion of intestinal capillaries and venules, intestinal wall congestion, edema, thickening, and deep red. Due to tissue hypoxia, capillary permeability increases, intestinal wall bleeding points, and blood exudation infiltrates into the intestinal cavity and abdominal cavity. With the development of blood circulation disorders, arterial blood circulation is blocked, thrombosis occurs, the intestinal wall loses vitality, and the intestine turns purple and black. The intestine may be ischemic and necrotic, ruptured and perforated.
