  • Assesses inflammatory bowel disease (IBD) such as ulcerative colitis and Crohn’s disease

  • Screens individuals above 45 years or those with a family history of colorectal cancer

  • Allows biopsy and polyp removal during the same procedure

Workflow

  • Step 1: Bowel Preparation Patient undergoes prescribed bowel cleansing to clear the colon.
  • Step 2: Sedation Mild sedation is administered for comfort.
  • Step 3: Scope Insertion A flexible colonoscope is gently inserted through the rectum.
  • Step 4: Visual Examination High-definition camera transmits images of the colon lining.
