Enteroscopy is the easiest, safest, and most effective way to detect intestinal tumors and precancerous lesions. But after all, endoscopy is an invasive examination, there are certain discomforts and complications, therefore, a lot of people are afraid of this kind of examination, resulting in some colorectal lesions and even tumors can not be diagnosed early, and delay the best time for treatment. With the progress of anesthesia drugs and medical monitoring technology, painless colonoscopy has emerged. In essence, it is a kind of anesthesia drug with fast onset, short effective time and precise effect injected intravenously before the examination, so that the patient will fall asleep in a few seconds, and wake up in the early stage after completing all the examinations, and there will not be any discomfort and pain in the process of the examination, which is therefore more and more popular among the patients. However, colonoscopy also has shortcomings, such as anesthesia accidents, sometimes the anesthesia recovery process is longer, the cost is more expensive.
The process steps of colonoscopy are as follows:
1, clean up the intestinal tract: there are many methods, and the medication used in each hospital is different. Bowel preparation should be carried out according to medical advice. Oral medication to clean the intestinal tract, after taking medication to drink more water, and finally discharged stool was water or light yellow, no fecal sludge, for the best intestinal cleansing effect.?
2, swallow the capsule and record: the examinee is required to wear an image recorder, and then in accordance with the doctor's instructions, water to take a capsule with endoscopy, that is, OMOM capsule endoscopy, swallowed, the capsule endoscopy began to work, with a rate of 2 seconds / photo, in the digestive tract under the peristalsis of the digestive tract throughout the digestive process, all the way along the way to shoot, real-time transmission of the image to the patient's pocket recorder, which can provide the best results for the patients. The images are transmitted in real time to the patient's pocket recorder, thus being able to provide a scientific basis for treatment.
3, playback observation: capsule endoscopy work after 8 hours and the capsule stops working, the doctor can remove the equipment, and then the results of the examination of the patient can be analyzed.
Dr. Golden Shield: can colonoscopy detect intestinal tumors?
In the vast majority of cases, colonoscopy can detect intestinal cancer, but there are rare cases that colonoscopy can not detect intestinal cancer, such as intestinal cancer in the early stage, the tumor is relatively small, or the tumor grows in the intestinal muscular layer, it is difficult to detect the presence of intestinal cancer when doing colonoscopy, it is very easy to miss the diagnosis of the situation.
To accurately detect bowel cancer, in addition to colonoscopy, other aspects of the examination and clinical manifestations can be combined, such as whether there is abdominal pain, blood in the stool, diarrhea, constipation, weight loss, general weakness, etc. People over 40 years of age, in particular, should pay attention to whether there is a family history of tumors, or a family history of intestinal cancer. If there is a family history of intestinal cancer, it belongs to the high-risk group of intestinal cancer, and they need to do regular medical checkups. If you have the above mentioned symptoms, besides colonoscopy, it is better to improve other auxiliary tests, such as imaging tests, like abdominal CT, etc., and you should consult a doctor in time, under the guidance of specialists, to improve the relevant tests, so that it is easy to detect intestinal cancer, so that the diagnosis is not missed.
The precautions to be taken after colonoscopy are as follows:
1. If it is an ordinary colonoscopy, you can eat after the examination. If it is a painless colonoscopy, usually eat after 6 hours. If there is a single polyp in the intestine, a liquid diet is usually required for 3 days after polyp removal, and a slag-free semi-liquid diet for 2 weeks. If there are more polyps, fasting is required on the same day;
2. Concerned about whether there is significant abdominal pain, or significant blood in the stool or bloating. Mild abdominal pain is not a big problem, if there is a little blood in the stool, but gradually reduced, or a slight abdominal distension, are no no special problems. If the more serious bleeding, abdominal pain, or obvious abdominal distension, you need to contact your doctor in time, and in some cases, such as hemorrhage, perforation, need emergency treatment.
