Endoscopic evaluation techniques

Endoscopic evaluation involves using a thin, flexible tube called an endoscope equipped with a camera to visually examine internal organs and passages, such as the digestive tract or respiratory system. The procedure allows doctors to identify abnormalities like inflammation, bleeding, or tumors directly. The endoscope is gently inserted through natural openings or small incisions, providing real-time images on a monitor. Techniques vary depending on the area being examined, including procedures like gastroscopy, colonoscopy, or bronchoscopy. Endoscopy is minimally invasive, offers detailed visualization, and often allows for biopsy or treatment during the same procedure.
