Four days before the procedure, the patient must eat a fiber-free diet (avoid beans, bran, corn, granola, etc.). The day before, the diet will be exclusively of clear liquids (chamomile, Gatorade, Powerade, clear soft drinks; clear, fresh strained broths, without seeds). You cannot eat any kind of solid food, cookies, or pureed vegetables. It is prohibited at all.
In the night before the exam and during the early morning, you must ingest a laxative, to cleanse the colon of the remains of stool that prevent an adequate evaluation of the organ.
To fully carry out the preparation before the study, we highly recommend to carefully read the text of the following link: Detailed preparation for Colonoscopy
At the “Clínica Digestiva Navarro” all procedures are performed under adequate sedation, the patient is guaranteed not to feel any discomfort.
Under sedation, the doctor performs a detailed inspection of the entire colon. Polyps can be found, which are abnormal growths, usually benign (not cancerous) that appear on the lining of the colon. They can be millimeter or several centimeters. They can be removed during the exam. Since cancer begins in polyps, their removal is essential to prevent colon cancer. This operation is known as a Polypectomy.
If the Colonoscopy is performed due to the appearance of lower digestive bleeding, the doctor can control the bleeding by injecting medications; cauterizing the bleeding blood vessels or placing small clips.
All the extracted polyps are sent for study by pathology (biopsy).
The patient will recover from the effects of sedation in a recliner. Your stomach may feel puffy from gas, but it is a temporary effect.
If the patient did not require cauterization of any polyp, it is allowed to eat after the procedure. If the person undergo a complex polypectomy, she or he should continue with a liquid diet.
The doctor will inform you of the results, will tell you if a biopsy was done and when it will be ready.
The day before the exam – during preparation – the medications are taken normally. The same applies to Diabetes, but it should be remembered that some of the clear liquids that will be ingested during the day must contain sugar to prevent hypoglycemia.
If the patient takes medicine for high blood pressure, heart or lung diseases, it is advisable to do so at least two hours before. Medications for the treatment of Diabetes Mellitus must be taken after the procedure.
If you take anticoagulants, you must inform them at the time you make the appointment.
Colonoscopy and polypectomy are generally safe when performed by doctors who have been specially trained and experienced in these procedures.
One of the possible complications is perforation or tearing of the intestinal wall, which may require surgery.
Bleeding may occur at the biopsy or polypectomy site, but is usually minor. Bleeding can stop spontaneously or can be controlled through the colonoscope, and medical follow-up is rarely required. Some patients may react to sedatives, or experience complications from heart or lung disease.
Although complications after colonoscopy are not common, it is important to recognize the early signs of them. If you notice severe abdominal pain, fever and chills, or rectal bleeding, contact the “Clínica Digestiva Navarro”. Be aware that bleeding can occur several days after the polypectomy.
