Colonoscopy
What is colonoscopy?
Colonoscopy examines the inside of the colon and rectum with a flexible camera. When appropriate, the doctor also examines the end of the small intestine. The procedure helps assess polyps, bleeding and inflammatory bowel disease. In addition, suitable findings may allow biopsy or treatment during the same examination.
Assoc. Prof. Dr. Muharrem Taşkoparan performs colonoscopy in Ankara at his YDA Center clinic. He plans preparation and sedation according to each patient’s health.
Who may need colonoscopy?
The doctor considers symptoms, medical history and personal risk. For example, colonoscopy may help investigate:
- Rectal bleeding or a positive stool blood test.
- Unexplained changes in bowel habits.
- Persistent unexplained diarrhoea or selected constipation cases.
- Unexplained weight loss, abdominal pain or iron deficiency anaemia.
- A family history of colorectal cancer or advanced polyps.
- Crohn’s colitis or ulcerative colitis diagnosis and follow-up.
Screening and follow-up intervals depend on individual risk and previous findings. Therefore, the same schedule does not suit everyone.
How do I prepare?
First, the specialist reviews your medicines and other conditions. Then he provides an individual bowel preparation plan. Good preparation helps him examine the bowel lining carefully. Tell him about blood thinners and diabetes medicines. Do not stop medicines on your own.
Sedation and recovery
Suitable patients receive sedation to support comfort during colonoscopy. However, the doctor selects the approach according to clinical needs. Without sedation, some patients experience cramping, pressure or gas discomfort. After the procedure, the team assesses recovery and gives individual discharge advice.
What happens if the doctor finds a polyp?
He assesses its size, shape, location and surface features. Suitable polyps may allow polypectomy during the same session. Larger or complex lesions may need EMR or ESD or another treatment. Then pathology helps guide follow-up.
Quality and careful examination
A high-quality examination requires adequate bowel preparation and a complete, careful inspection. The doctor reviews suspicious areas and manages lesions appropriately. In addition, he considers the terminal ileum when clinically necessary. Technology supports this assessment but does not replace specialist judgement.
Frequently asked questions
Does colonoscopy completely prevent cancer?
No. Detecting and removing suitable precancerous polyps can help reduce colorectal cancer risk. However, no screening method eliminates all risk. Follow-up remains important.
Can endoscopy and colonoscopy take place together?
Yes, when both procedures are medically necessary and suitable for the patient. The doctor also checks sedation suitability and bowel preparation.
How often do I need colonoscopy?
The specialist considers age, family history and previous polyp findings. Bowel preparation and personal risks also affect the interval. Therefore, ask for an individual follow-up plan.
