Endoscopy: Types, Uses, and What to Expect

Endoscopy uses a flexible or rigid tube with a camera and light (endoscope) to visualize internal organs. It serves both diagnostic (detect lesions, ulcers, tumors) and therapeutic (remove polyps, stop bleeding, dilate strictures) purposes.

Common Types

1. Upper GI Endoscopy (EGD): Esophagus, stomach, duodenum.
2. Colonoscopy: Colon and rectum.
3. Bronchoscopy: Airways and lungs.
4. Cystoscopy: Bladder and urethra.
5. Arthroscopy: Joints (knee, shoulder, hip).
6. Laparoscopy: Abdominal/pelvic cavity.

Preparation & Safety

• Fasting required for GI procedures.
• Sedation or local anesthesia for comfort.
• Generally safe; rare risks: perforation, bleeding, infection.
