Colonoscopy is an examination of large intestine process. Examination is conducted by using tipped light, thin (10-12 mm diameter) tubular flexible device called "colonoscopies". While the final parts of intestines close to anus are examined in the procedure called "flexible sigmoidoscopy" entire large intestine is examined in colonoscopy. 

Colonoscopy is applied in cases such as abdominal pain, constipation, diarrhea, irregular bowel habits, anaemia, digestive tract bleeding, unexplained weight loss. In addition, it may be required in case of detecting abnormal findings in relation to large intestines in radiological investigations. 

During colonoscopy, some drugs are administered intravenously to patients for them not to feel any pain or discomfort. This procedure lasts for 20-30 minutes. All segments of the colon with colonoscopy are examined in detail. In special cases, merging area of large intestine and small intestine is investigated and the final parts of small intestines can be examined. During the procedure, water is supplied to inside of the intestine with the help of the device and in this way, all folds of the intestine can be seen.

For this reason, following this procedure, a sense of bloating can be experienced. 

While performing colonoscopic examination, it is understood whether there is inflammatory disease in the large intestines, presence of cancer, there are lesions called "polyps" and bearing the risk of transforming into the cancer in the future. In case of such abnormal findings in large intestines, you can diagnose this visually and sometimes biopsy can be conducted for histopathological diagnosis.  In case of detecting polyps, these polyps can be cut off and removed with the help of electrocautery and thus the intestine cancer likely to develop in the future is avoided. In addition, bleeding lesion can be also intervened in large intestine bleeding.. Operations such as drug injection, burning the vein with the help of electrocautery or covering the wound by using special tools called endoclips can be implemented for the bleeding area for bleeding control.

Following completion of colonoscopy procedure, the patient is kept under observation by resting in the resting room for a period of approximately 1-1.5 hour. Totally losing effect of the drug administered intravenously generally lasts for 4-5 hours. Thus, it is recommended that the patients leave the endoscopy unit following the operation with an attendant and the patient should be rest at home since they may thoughtfulness, attention deficit, slowing reflexes and drowsiness.
