Endoscopy is a medical procedure where a doctor uses an endoscope—a long, thin, flexible tube with a camera and light attached—to view the inside of your body.

The endoscope is typically inserted through a natural opening, such as the mouth or anus, or a small incision. According to research from the American Society for Gastrointestinal Endoscopy (ASGE), endoscopy is a critical tool for diagnosing and treating various conditions.

1.1. What is the Purpose of Endoscopy?

Endoscopy serves multiple purposes, including:

• Diagnosis: Identifying the cause of symptoms such as abdominal pain, bleeding, or swallowing difficulties.
• Screening: Detecting early signs of diseases like cancer.
• Treatment: Performing procedures like removing polyps, stopping bleeding, or widening narrowed areas.

1.2. Which Areas of the Body Can Endoscopy Examine?

Endoscopy can be used to examine various parts of the body:

• Upper Endoscopy (Esophagogastroduodenoscopy or EGD): Examines the esophagus, stomach, and duodenum (the first part of the small intestine).
• Colonoscopy: Examines the entire colon and rectum.
• Sigmoidoscopy: Examines the lower part of the colon (sigmoid colon) and rectum.
• Bronchoscopy: Examines the airways (trachea and bronchi) in the lungs.
• Cystoscopy: Examines the bladder.
• Arthroscopy: Examines joints, such as the knee or shoulder.
