What diseases can be detected by colonoscopy? What diseases do I need to be examined by colonoscopy?

Colonoscopy is to help screen for colon lesions, the most common is colon cancer screening, colon cancer screening is not only to find advanced tumors, but also very helpful for early precancerous lesions, such as multiple muscles, such as flat-growing, side-growing tumors, these are the places to pay attention to early colonoscopy screening. In addition, there are some patients with blood in the stool, colonoscopy is done to identify the cause of blood in the stool, blood in the stool may be ischemic bowel disease, ulcerative colitis, or colonic diverticulum bleeding, through colonoscopy can identify the specific cause of bleeding. Colonoscopy can also help to determine some perianal lesions, and flipping the endoscope during colonoscopy is also beneficial to the examination of perianal lesions.

Colonoscopy can detect many diseases, such as gastrointestinal diseases such as bleeding, polyps, tumors, etc.; Colonoscopy can also identify the cause of gastrointestinal bleeding or chronic diarrhea, which is convenient for doctors to treat symptoms**; A colonoscopy may also be used to check recovery from rectal or colon cancer surgery.

The main types of diseases examined by colonoscopy are as follows:

1. Unexplained gastrointestinal bleeding, especially lower gastrointestinal bleeding, such as repeated bright red and dark red bloody stools or persistent positive fecal occult blood;

2. Chronic and long-term diarrhea of unknown cause, colon lesions are considered;

3. Colorectal disease should be considered if there are lower gastrointestinal symptoms, such as abdominal pain under the umbilicus, right lower abdominal pain, left lower abdominal pain or constipation, abdominal mass, change in bowel habits, etc.;

4. If colorectal disease is suspected by other examinations, such as barium enema or imaging examination, colonoscopy is also performed to clarify the nature of the disease;

5. Colonoscopy can be used for the diagnosis or differential diagnosis of inflammatory bowel disease, and it is necessary to determine the extent of the lesion or the recovery situation;

6. Rectal polypectomy;

7. Surgery requires colonoscopy to assist in exploration or**.

There are many intestinal diseases that can be detected by colonoscopy, such as enteritis, intestinal polyps, intestinal cancer, etc., as long as there are abnormal manifestations of these diseases in the intestine, they can be accurately determined through colonoscopy, and Chang'an cardiac fecal genetic testing can effectively screen for early intestinal problems.

Colonoscopy can generally detect intestinal diseases, first of all, infectious diseases, such as acute chronic enteritis, colitis or proctitis. Secondly, colonoscopy can also determine whether the patient has organic lesions in the intestine, such as intestinal polyps, colon cancer or rectal cancer, etc., if the patient has intestinal polyps, it is necessary to go to the hospital regularly for colonoscopy.

Colonoscopy can detect colon inflammation, ulcers, tumors, parasitic lesions, and unexplained diarrhea. The mucosa of the anal canal, rectum, colon, and ileocecal region was observed by colonoscopy. The process of pathological and cytological examination of living organisms can also be performed.

Colonoscopy can detect intestinal polyps, proctitis, colorectal cancer, ischemic bowel disease, intestinal tuberculosis, etc.

Colonoscopy is a traditional colorectal cancer screening method, which is painful and has poor compliance. Before colonoscopy, it is recommended to do a stool DNA test in Chang'an, which can greatly improve colonoscopy compliance.

What diseases can be detected by gastroscopy? A gastroscopy can only check for diseases in the stomach or intestinal diseases.

Colonoscopy can generally detect intestinal diseases.

Colonoscopy generally refers to colonoscopy, which includes the rectum, colon, cecum, and mucosa at the end of the ileum. Colonoscopy can detect the following conditions:

1. Benign space-occupying lesions, such as polyps, lipomas, cysts, etc., these benign diseases have no symptoms and are generally found during physical examination. If polyps are found, they can be done endoscopically** and small polyps can be removed on the spot. If the polyp is large and needs to be hospitalized, the polypectomy will be performed again with a gastroscopic polypectomy.

Benign lesions such as lipomas and cysts can be followed up regularly and do not require special treatment;

2. Various malignant tumors such as colon cancer, lymphoma, neuroendocrine tumors, etc. Colon cancer and lymphoma often have corresponding clinical manifestations, and neuroendocrine tumors are generally asymptomatic and are also found during physical examination;

3. Mucosal lesions, such as ulcerative colitis, ischemic enteritis and colonic melanosis.

The most important preparation before colonoscopy is to clean up the intestines of feces, as fecal and food residues can affect the results of colonoscopy. People with constipation should take laxative medications, most commonly lactulose, a week before the week.

Long-term abdominal pain and diarrhea, or blood in the stool, long-term stomach pain, long-term constipation and other conditions need to do colonoscopy, only colonoscopy can see the inside of the intestines, so as to confirm the diagnosis**.

General colonoscopy is currently the easiest, safest and most effective method to detect intestinal tumors and precancerous lesions. The patient will need to eat a liquid diet the day before the colonoscopy and fast on the morning of the examination. Colonoscopy may be performed for general abdominal pain, tenesmus, bloody stools, changes in bowel habits, chronic diarrhea, constipation, constipation, constipation, anemia, unexplained weight loss, and fatigue.

Long-term diarrhea, abdominal pain, constipation, internal hemorrhoids, intestinal polyps, and rectal cancer all need to be colonoscopy, which can effectively see the situation in the intestine and can have a good effect on intestinal disease examination.

If you suffer.

Patients with anorectal diseases need to do colonoscopy, anorectal diseases, changes in bowel habits, blood in the stool, mucus in the stool, abdominal pain and bloating in the stool, and abnormal shape of the stool, as well as diarrhea caused by unknown causes, etc., these are all required to do colonoscopy.

Colonoscopy is necessary for these 8 conditions.

Colonoscopy is an examination that shows the inner surface of the colorectum through a bendable, light-sourced tube, which can observe whether there are lesions in the entire intestinal lumen, and can also clamp small pieces of diseased tissue for pathological examination, which helps to clarify the diagnosis and judge the severity of the disease, and then guide **, such as the removal of colorectal polyps and early cancer under colonoscopy, and hemostasis under colonoscopy.

01 Those with symptoms such as blood in the stool, black stool, etc., or those with a positive long-term fecal occult blood test; Those with mucus, pus and blood in the stool; Those who have frequent and unformed stools, or diarrhea; Those who have recently had difficulty defecating or having irregular stools; Those who have thinned and deformed stools; Long-term chronic constipation, which cannot be cured for a long time;

02 Unexplained weight loss and emaciation; People with unexplained anemia; Unexplained abdominal mass, for which a clear diagnosis is required; Those with unexplained elevated CEA (carcinoembryonic antigen).

03 Patients with long-term abdominal pain and bloating; Chronic colitis, long-term medication, long-term treatment; Patients who have suffered from schistosomiasis, ulcerative colitis and other diseases;

04 Those who suspect colon tumors, but have negative barium enema and X-ray examination; Patients with thickened intestinal wall found by abdominal CT or other examinations, and colorectal cancer needs to be excluded; Lower gastrointestinal bleeding, the bleeding lesion can be found, the cause of bleeding can be determined, and the bleeding can be stopped microscopically if necessary; Those who have been found to have colon polyps that need to be removed under colonoscopy;

05 Colonoscopy should be rechecked regularly after colorectal cancer surgery: Generally, colonoscopy should be rechecked every 6 months to 1 year, if the colonoscopy fails to examine all the colons due to colon obstruction before surgery, colonoscopy should be performed 3 months after surgery to determine whether there are colon polyps or colon cancer in other parts;

06 Colonoscopy should be rechecked regularly after colorectal polyp surgery: villous adenoma, serrated adenoma and high-grade epithelial neoplasia polyps are easy to ** and cancerous, it is recommended to recheck the colonoscopy every 3-6 months, and it is recommended to recheck the colonoscopy every 12 months for other polyps, and if the re-examination colonoscopy is negative, it will be rechecked after 3 years;

07 Patients with a family history of colorectal cancer should undergo colonoscopy screening, and people with a family history of colorectal polyps should also undergo colonoscopy screening;

08 People over the age of 40, especially those with a long-term high-protein and high-fat diet and long-term alcoholism, it is best to have a colonoscopy for routine physical examination in order to detect some asymptomatic early colorectal cancer as early as possible.

Abdominal pain, diarrhea, constipation, blood in the stool. There are also gastrointestinal diseases, which need to be diagnosed through this to be more accurate.

Colonoscopy is currently the easiest, safest and most effective method to detect intestinal tumors and precancerous lesions. Indications: Colorectal polyps; inflammatory diseases of the large intestine such as ulcerative colitis; chronic colitis; colon cancer, etc.

Which types of patients need this test?

1. Unexplained lower gastrointestinal bleeding. 2. Chronic diarrhea of unknown cause; 3. Unexplained low intestinal obstruction; 4. Suspected tumor of the large intestine or terminal ileum; 5. Colorectal polyps, tumor bleeding and other lesions need to be colonoscopy**; 6. Patients who need to have regular re-examination of colonoscopy after colon surgery and colonoscopy**; 7. Colorectal cancer screening. 8. Patients with colorectal cancer or adenoma in their family who need to undergo physical examination.

9. Health examination for people over 40 years old who have never had colonoscopy.

It can be checked for all diseases in the intestine, such as enteritis, bowel cancer, intestinal polyps, etc.

Colonoscopy can detect acute enteritis, chronic colitis, chronic proctitis, radiation proctitis, constipation proctitis, Crohn's disease, ulcerative colitis, intestinal tuberculosis, bowel cancer (rectal cancer, colon cancer), colon polyps, rectal polyps, hemorrhoids (internal hemorrhoids), anal fissures, anal canal cancer, anal sinusitis, etc.

Through colonoscopy, you can observe whether there are polyps, tumors, inflammation, vascular abnormalities, diverticulum, etc. in the intestinal lumen, and can effectively observe whether the mucosa at the end of the colorectum or ileum is abnormal. In addition, if the patient needs to have a gastroscopy and a colonoscopy, both tests can be done at the same time.

Advantages of colonoscopy:

It can directly observe the lesion.

b. Biopsy can be performed for pathological examination.

cSome colon lesions can be treated microscopically, such as resection of colon adenoma can reduce the incidence of colorectal cancer (6% 90%)

d. Colonoscopy is costly and painful for patients.

Colonoscopy combined with biopsy is currently the most reliable method for clinical diagnosis of colorectal cancer. However, because it is generally not used for primary screening, it is used for primary screening positive.

Colonoscopy is mainly for the examination of the colon, which helps in the diagnosis of various diseases of the intestine, colonoscopy and biopsy can find colon tumors and various inflammatory lesions, such as Crohn's disease, ulcerative colitis, colon polyps, etc.
