Colonoscopy

Colonoscopy

 

Colonoscopy is a screening procedure that enables the examiner to look inside the large intestine (rectum and colon) for polyps, abnormal areas, tumours or cancer. A colonoscope which a thin, tube-like instrument with a light and lens for viewing, is inserted through the rectum into the colon. The apparatus also has a tool to remove polyps or tissue samples, which are checked under a microscope for signs of cancer or other disease.

Why is it done?

  • To check for colorectal cancer or polyps
  • To check for the cause of blood in the stool or rectal bleeding
  • To check for the cause of dark or black stools
  • To check for the cause of chronic diarrhoea
  • To check for the cause of iron deficiency anaemia
  • To check for the cause of sudden, unexplained weight loss
  • To check the colon after abnormal results from a CT scan, MRI, virtual colonoscopy, stool test, or barium enema
  • To watch or treat inflammatory bowel disease (IBD)
  • To check for the cause of long-term, unexplained stomach pain

A sigmoidoscopy is often used as a screening procedure for a full colonoscopy.

Preparation

  • The colon must be free of solid matter before the test is conducted
  • The patients may be asked to follow a low- fibre or all liquid diet
  • The day before the procedure, the patient is usually given a laxative preparation
  • The patient may be asked to skip any paracetamol or paracetamol like products

Colonoscopy is always conducted on a doctor’s advice. Usually, patients are admitted a day ahead for such procedures, but the unique design and special care for day surgery at Apollo Clinics makes it possible for the patient to undergo this test in a single day without any hassles, which also implies that you can join your family for dinner the same day.
