Diagnosis of many colon diseases, such as colon cancer, polyps, inflammatory bowel diseases, ulcers or diverticula, early detection of changes
A colonoscopy is an endoscopic examination of the lower gastrointestinal tract. It allows for the examination of the large intestine by inserting a flexible tube, about the thickness of the index finger, with a camera at the end into the anus. The endoscope tube is inserted into the large intestine through the rectum. The examination is unpleasant and uncomfortable for the patient, but its diagnostic value is significant.
Colonoscopy allows for the detection and often immediate removal of lesions that are not known because they do not yet produce any symptoms, such as polyps and benign adenomas that form on the inner walls of the intestine.
The examination typically takes 20 to 30 minutes. The patient lies on their side, and the doctor inserts a colonoscope into the rectum to analyze the colon. Polyps may be removed or tissue samples may be taken during the examination. If general anesthesia is used, the patient may be asleep during the examination.
Diabetics should inform their physician and laboratory staff immediately after their appointment. Pregnant and breastfeeding women should consult with their physician about how to prepare for the test. Iron supplements should be discontinued 7 days before the test. Fruits containing pits, breads with seeds, muesli, flax seeds, poppy seeds, etc. Beetroot is also not recommended! They can distort the color of the intestinal lining.
Three days before the colonoscopy, a liquid diet should be followed.
A special laxative should be taken the day before the test. After taking the medication, it is recommended to drink plenty of fluids, approximately 3 liters per day.
On the day of the test, refrain from eating. Drinking still water is permitted. Thoroughly wash the anal and perineal area before the test.
An endoscopic examination involves inserting a special endoscope into the large intestine through the rectum. A flexible instrument called a colonoscope is used, ranging in length from 130 to 200 cm. The viewing channels in the endoscope allow for the presentation of images from the interior of the digestive tract. Polyps can be removed during the examination. The procedure is painless, and patients can return to their daily activities immediately afterward. Colonoscopy is performed under local anesthesia or general anesthesia (sedation).
If the examination is performed under anesthesia, the patient is usually observed for 1-2 hours. In rare cases, longer observation may be necessary. Driving and drinking alcohol are not permitted for 12 hours after the procedure. After the examination, you may experience bloating and cramping caused by air introduced into the intestine during the examination.
Colonoscopy is recommended for symptoms such as chronic abdominal pain, rectal bleeding, abnormal stool test results, and as a preventative measure against colon cancer in people over 50 or those at higher risk.
Before a colonoscopy, patients must follow their doctor’s dietary recommendations, typically starting with light meals and switching to fluids for one to two days before the test. Laxatives are also necessary to thoroughly cleanse the intestines.
Colonoscopy is usually not painful, although it can be somewhat uncomfortable. To minimize discomfort, patients are often given sedation or anesthesia, which makes the procedure well-tolerated by most people.
