Colorectal malignancy refers to the malignant change from the tooth line to the junction of the rectal sigmoid colon. It is one of the most common malignant changes in the digestive tract. However, due to the low malignant position, it is easy to be regarded as digital rectal diagnosis and sigmoidoscopy diagnosis.

At present, colorectal (colorectal) malignancy is still one of the major cancers that threaten human health. My knot

The primary treatment for malignant colon is surgery. Since the majority of large bowel malignancy is a polyp type, if the malignant change occurs at the top of the polyp, and it is an early malignant change, it can be removed under colonoscopy without having to open the colon to remove the colon. If the malignancy occurs at the root of a polyp, or is an ulcerative malignancy or a suspected metastatic malignancy, the bowel must be removed by laparotomy. Whether chemotherapy or radiotherapy should be performed after surgery depends on whether the malignant metastasis has metastasis, the degree of differentiation of the malignant change, and the overall situation of the patient. The choice of these methods is up to the doctor. The currently popular immunotherapy and traditional drug therapy can also be used as a supplement or supplement to the above treatment methods, and can assist or strengthen the treatment effect of large bowel malignancy at the appropriate time. Patients should be reminded that: Do not jeopardize disease and avoid medical treatment; Mo Qingxin "prescription cures serious illness", delaying the best time for surgery; comprehensive treatment is still an important principle for treatment of malignant intestine.

When to review after a large bowel malignancy?

Patients and family members often ask if a colonoscopy should be performed after the malignant intestine, and when is it appropriate?

Relevant data show that: 75% of patients undergoing colonoscopy after malignant intestine have multiple colorectal diseases, especially recurrent colorectal cancer, multiple primary colorectal cancer, colorectal polyps, and anastomotic diseases, which affect the patient's life. And life has an important impact, so regular colonoscopy after surgery is very necessary. The large intestine in adults is generally 1.5m, and usually about 1m remains after surgical resection.

Patients with colorectal malignancy are 3-6 times more likely to suffer from colorectal malignancy after surgery than normal people. The incidence of large bowel polyps after large bowel malignancy is 5 times higher than that of the general population. From the above, it is extremely important for patients to undergo regular colonoscopy after malignant intestine. The specific follow-up plan is as follows: Generally, it should be checked every 3-6 months within 2 years after surgery; every year within 2-4 years; those who have no abnormal findings are checked every 2 years until lifelong.

The inspection items include: (1) digital anal examination; (2) fecal occult blood test; (3) x-ray photograph of the chest and lateral position; (4) colonoscopy; (5) ultrasound examination; (6) CT examination; 7) Blood routine, biochemical and liver function; (8) CEA, CA19-9 (glycobodies 19-9).

In the early stage of the large intestine, the malignant tissue is small and confined to the mucosa, and often has no obvious clinical symptoms. Although there may be a small amount of bleeding, it is difficult to detect with the naked eye. With the increase of malignant tissue, on the one hand, it will lead to the narrowing of the intestinal cavity; on the other hand, the tissue grows too fast and the blood supply cannot meet the needs of malignant growth. Three groups of symptoms:

(1) Abnormal defecation, that is, rectal irritation symptoms, such as frequent loose stools. When you fall, you don't feel full, even if you are anxious, and can be accompanied by abdominal distension and lower abdominal discomfort;

(2) Feces are abnormal, such as bloody stools, mucus stools, or pus and bloody stools. There is even thinning of feces;

(3) Symptoms of obstruction are malignant swelling and obstruction of the rectum, difficulty in defecation, closed stools, abdominal pain, and bloating. Even bowel type can be seen with hyperthyroidism. If the surrounding tissues and organs are violated, symptoms of corresponding organ lesions may appear, such as local anal canal invasion. Involvement of the anal sphincter can cause incontinence, and pus and blood often overflow outside the anus. Anterior invasion and urinary system may appear frequent urination, pain, and difficulty urinating. When the phrenic nerve plexus is invaded backwards, persistent severe pain in the crotch and perineum occurs, and pain in the lower abdomen, waist and thighs is involved. When the malignant metastases are transferred to the liver, hepatomegaly, jaundice, and ascites may be present. Advanced patients may have wasting, anemia, edema or cachexia.

It is understood that the high incidence of bowel malignancy and younger trends are closely related to people's diet. In reality, the cause of colorectal malignancy is often not very clear, and the early symptoms are not obvious. Once found, most of the disease has progressed to advanced stages. Therefore, the most effective way to prevent large bowel malignancy is to detect malignant changes as early as possible, such as performing colonoscopy.

Experts emphasize that according to clinical experience, there are mainly seven types of people with high incidence of large bowel malignancy:

high-protein, high-fat diet, smokers and drinkers.

There are patients with malignant intestine in the family.

have had polyps in the large intestine.

Cholecystectomy for more than 10 years.

Severe ulcerative colitis does not heal for many years.

Have received lower abdominal radiotherapy and repeated blood in the stool for unknown reasons.

Stool habits and stool traits have changed for a period of time.

Experts recommend that: middle-aged people over 40 years of age should include colonoscopy in routine physical examinations and do it once a year in order to detect the large bowel malignancy early. Intestinal malignancy is a common malignant change in the gastrointestinal tract. Its incidence is second only to gastric and esophageal malignancy. It is the most common part of large bowel malignancy, accounting for about 60%. The vast majority of patients are over 40 years old, about 15% are under 30 years old, and more common in men.

Relationship between malignant intestine and "polyp" in large intestine

The so-called "polyps" refer to various bumps that grow in the intestines (mucosal surface). Medically speaking, this polyp is divided into two types: malignant and non-malignant. The former is called adenoma, which is a real benign malignancy. The latter polyp is not malignant. In fact, not all adenomas need to be malignant. The most prone to malignancy is the aforementioned "familial adenomatous polyposis". This adenoma can have abdominal pain, diarrhea, blood in the stool, or it can be asymptomatic until it is discovered after the malignancy. It has been observed that this disease mostly occurs around the age of 20, symptoms occur around the age of 33, malignant changes around the age of 39, and the average age at death is only 42 years old. Studies have found that 80% of these patients have "congenital retinal pigmented epithelial hyperplasia". As a sign, suspects can find clues to the disease through eye examinations (fundoscopy). Because the disease is family-accumulating, if one person in the family is diagnosed, other members should be examined (including fundus examination).

Some of these "adenomas" are associated with malignant changes in the skin, muscles, bones, or brain. Some are associated with skin and mucous melanoma (pigmentation of the palms and lips), and some are accompanied by atrophy of nails, hair loss, and dark skin. . Because polyps grow in the intestine and cannot be diagnosed without special inspection, we can remind us to go to the doctor through the above-mentioned characteristic manifestations.

Plant fiber prevents large bowel malignancy

Studies have shown that eating food plants rich in plant fiber reduces the incidence of large bowel malignancy. Colorectal malignancy refers to malignant lesions of the large intestinal mucosa caused by environmental or genetic factors, such as malignant lesions, which have a poor prognosis and a high mortality rate. It is one of the common malignant changes in China. It includes malignant rectum and colon.

Recently, a large-scale study of European and American dietary habits and early symptoms of malignant bowel disease has shown that eating more foods rich in plant fiber can reduce the incidence of malignant bowel disease.

The British and French get plant fibers from vegetables, the Dutch and Germans get plant fibers from grains, and the Italians and Spanish get plant fibers from fruits, but scientists say that no matter where the plant fiber comes from, it can Reduce the risk of intestinal malignancy.

The study, which involved more than 500,000 people in 10 European countries, was the largest sample in the study of the relationship between diet and malignancy. The results showed that if people doubled their intake of foods rich in plant fiber, their risk of malignant intestines would be reduced by 40%. Scientists say that you should eat more pasta made of fruits, vegetables and whole grains, and eat less meat and fatty foods.

After investigating about 3600 people with benign colonic malignancies and 34,000 normal people, scientists at the institute reached the same conclusion.

Another report states that colonic malignancy and malaria are not common in developing countries, but in developed countries more than 490,000 people die each year from these two malignancies.

Although European studies show that the source of plant fiber intake varies from country to country, experts agree that the more plant fiber intake, the better the effect and the less the incidence of large bowel malignancy.
