About Colonoscopy

Colonoscopy is an advanced endoscopic procedure used to examine the inner lining of the large intestine (colon and rectum). It helps detect polyps, inflammation, ulcers, bleeding sources, and colorectal cancer.

Overview

  • Detects colorectal cancer and precancerous polyps

  • Evaluates chronic abdominal pain, diarrhea, or rectal bleeding

  • 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.

Step 5: Biopsy / Polypectomy (If Required)
Suspicious tissue or polyps are removed for laboratory analysis.

Step 6: Reporting
Findings are documented and discussed with the patient.
