What causes incomplete intestinal obstruction?

Incomplete intestinal obstruction is usually caused by a blockage in the flow of intestinal contents that is not completely interrupted. Common causes include adhesions, tumors, inflammation, or a twisting of the intestine. Treatment depends on the cause, including drugs, surgery, or lifestyle changes.

1. Intestinal Adhesion

Intestinal adhesions are a common cause of incomplete intestinal obstruction and are often caused by abdominal surgery, infection, or inflammation. Adhesions can cause the intestine to twist or narrow, affecting the passage of contents. Mild adhesions can be treated with medications, such as anti-inflammatory drugs or drugs that promote intestinal peristalsis. Severe adhesions may require surgical release.

2. Tumor

Intestinal tumors may compress or block the intestinal lumen, causing incomplete obstruction. Benign tumors such as polyps can be removed endoscopically, while malignant tumors require surgery combined with radiotherapy and chemotherapy. Early detection and treatment are key, and regular physical examinations can help prevent them.

3. Inflammation

Inflammatory bowel diseases such as Crohn's disease or diverticulitis may cause the bowel wall to thicken or narrow, leading to obstruction. Anti-inflammatory drugs such as corticosteroids or immunosuppressants can relieve symptoms. Dietary changes such as a low-fiber diet can also help reduce bowel burden.

4. Intestinal volvulus

Intestinal volvulus is a twisting of the intestine that causes obstruction, often related to congenital anatomical abnormalities or strenuous exercise. Mild torsion can be treated with manipulation or medication, while severe torsion requires emergency surgery to avoid intestinal necrosis.

5. Other factors

Incomplete intestinal obstruction may also occur due to fecal impaction, intussusception, or external compression. Fecal impaction can be resolved with an enema or oral laxatives, while intussusception requires prompt medical attention.

The treatment of incomplete intestinal obstruction should be combined with the cause and the severity of symptoms. Drugs such as prokinetic drugs, anti-inflammatory drugs or laxatives can relieve symptoms, and surgeries such as adhesion lysis, tumor resection or intestinal volvulus reduction can cure the cause. In terms of diet, it is recommended to choose easily digestible, low-fiber foods and avoid overeating. In terms of exercise, moderate activities such as walking can help promote intestinal peristalsis, but strenuous exercise should be avoided.

The causes of incomplete intestinal obstruction are complex and treatment needs to be individualized. Early identification of symptoms such as abdominal pain, bloating, constipation, or vomiting and timely medical attention are key. Most patients can effectively relieve symptoms and prevent recurrence through medication, surgery, or lifestyle adjustments. Regular physical examinations and healthy lifestyle habits can help reduce the risk of disease.
