Typical case: A year ago, Mr. Song, 42, unintentionally found himself with blood in his stool. At first, he thought it was hemorrhoids, so he went to the pharmacy to buy hemorrhoid cream to use, but it never got better. After coming to Shenyang Anorectal Hospital, the doctor suggested that he do colonoscopy, Mr. Song was afraid, delayed for some time, the blood in the stool is still not good, mental state is not as good as before. Under the persuasion of his wife and friends and relatives, Mr. Song finally had a colonoscopy, and found that there was a 2 cm diameter polyp with a tip 30 cm from the anus, and after hospitalization, he underwent a colonoscopic high-frequency electric resection. The postoperative pathology suggested: “choroidal adenoma with low-grade intraepithelial neoplasia. After being discharged from the hospital, Mr. Song did not find blood in his stool again and came back to the hospital six months later with a better complexion and weight gain. The actual blood in the stool is not always hemorrhoids Kang Liqiang introduced, the symptoms of blood in the stool is not always hemorrhoids, hemorrhoids blood in the stool is bright red, for hand paper stained blood, dripping blood or jet-like bleeding after the stool; colon polyps caused by blood in the stool more mixed with stool, darker color. Blood in the stool caused by hemorrhoids and dysenteric enteritis is sometimes not easily distinguished from blood in the stool caused by colorectal polyps and colorectal cancer, and should be clearly diagnosed by colonoscopy.
In addition, there are still some cases of black or brown-black patches on the lips of the mouth, cheek mucosa, fingers, palms and toes.
Colonoscopy intuitive detection of intestinal polyps colorectal polyps, especially adenomatous polyps is a common clinical disease closely related to colorectal cancer, because polyps hidden in the depths of the large intestine, with general laboratory tests, X-rays, and even CT, MRI and other new technologies are often not easy to detect early, so that many patients with colorectal polyps because of the final cancer lost the time of valuable treatment, regrettably.
Colonoscopy can look directly at the lesions in the intestinal cavity and can take samples for pathological sectioning to clarify the nature of the lesions, which is currently the most accurate and intuitive way to confirm the diagnosis of colon polyps, not only to clearly identify intestinal lesions, but also to treat some of the intestinal lesions.
Colonoscopy is not terrible Kang Liqiang said, many people have fear of doing colonoscopy, can delay. In fact, the colonoscopy technology has become increasingly mature, and the pain is greatly reduced. The colonoscope is inserted through the anus and can examine the rectum, sigmoid colon, descending colon, transverse colon, ascending colon and cecum, as well as a small section of the small intestine (ileocecal end) connected to the large intestine. A colonoscopy is performed through the curved part of the intestine with a small amount of inflation and slight discomfort, which most people can tolerate calmly.
Before the colonoscopy, you only need to eat a liquid or semi-liquid diet 3 days before the examination, fast in the morning of the examination, take laxatives such as mannitol, lactulose and polyethylene glycol electrolyte dispersion to cleanse the intestine according to the needs of different examinations, and have 7-8 or more bowel movements with clear water-like stools, then you can do the colonoscopy. If no pathology is taken during the colonoscopy, and the stomach is not distended after one or two hours of rest, you can eat a small amount of liquid food and resume normal work and study the next day.
At present, with the continuous development of colon endoscopic treatment technology, endoscopic removal of colon polyps has been carried out quite commonly and mature, most of the colon polyps can be cut under the colon endoscope, eliminating the pain of dissection and having the same treatment effect as open surgery, and the hospital stay is short, the postoperative recovery is fast and the treatment cost is low.
According to the shape, size and number of polyps, different methods can be used for treatment. For example, high-frequency electrocoagulation capsulectomy is mainly used for large polyps with tips, thermal biopsy forceps removal is mainly used for single small polyps, mucosal resection is mainly used for flat polyps without tips or early cancer patients, and block and stage removal is suitable for larger polyps. If the number of polyps is large and if they cannot be removed all at once, the patient is required to undergo regular fractionated electrodesiccation. Those who cannot be removed endoscopically will require surgical treatment. After removal of polyps, regular review should be performed according to the condition.
