Overview.
Nonspecific functional bowel disease is a condition in which the specificity or frequency of intestinal symptoms is not sufficient to diagnose a particular functional bowel disease, such as irritable bowel syndrome, functional bloating, functional constipation, and functional diarrhea, and evidence of organic disease is lacking. Its etiology is still unclear, and it can be treated symptomatically based on the main symptoms.
Etiology
The etiology and pathogenesis of this disease are still unclear, and the main possible pathogenic factors are psychogenic factors and abnormal gastrointestinal dynamics.
Symptoms
Symptoms of this disease are common in the general population, with no obvious specificity, including abdominal pain, abdominal distension, changes in bowel habits and abnormal stool characteristics, mucus stools and other manifestations, and its persistence and recurrent episodes are its characteristics.
Examination
1. Laboratory examination
Routine stool culture is negative, fecal occult blood test is negative, blood and urine routine is normal, blood sedimentation is normal, thyroid, liver, gallbladder, pancreas and kidney function are normal.
2. Colonography
If there are intestinal lesions, colonography can determine the scope of the lesions; if there are no lesions, the test can exclude organic intestinal lesions.
3. Measurement of intestinal passage time and pressure measurement
It can exclude irritable bowel syndrome.
4. Endoscopy
If there are lesions in the intestine, endoscopy can directly observe the lesions in the intestinal lumen, determine their location and scope, and can be photographed, biopsied or brushed, which greatly improves the diagnostic accuracy of intestinal organic lesions; if there are no lesions in the intestinal tract, this examination can exclude intestinal organic lesions.
Diagnosis
The diagnostic points of non-specific functional enteropathy are as follows.
1. The intestinal symptoms cannot be attributed to organic diseases and do not meet the diagnostic criteria for irritable bowel syndrome, functional bloating, functional constipation and functional diarrhea.
2. The disease can be diagnosed by the persistence and recurrence of intestinal symptoms for at least 6 months prior to diagnosis.
Treatment
The mainstay of treatment is to find and remove the contributing factors and symptomatic treatment to alleviate the symptoms.
1. Adjustment of diet
Learn more about the patient’s dietary habits and their relationship to symptoms, avoid sensitive foods, avoid excessive fat and stimulating foods such as coffee, strong tea, alcohol, etc., and reduce the intake of gas-producing foods (dairy products, soybeans, lentils, etc.).
2. Psychological and behavioral treatment
Provide patient psychological treatment to patients to relieve anxiety and tension. For those with severe insomnia, anxiety and other symptoms, sedative drugs and anti-anxiety drugs can be given appropriately. Traditional Chinese medicine can also be used.
