Endoscopic methods are medical procedures that use an endoscope, a flexible tube with a light and camera, to visualize the inside of the body. These techniques allow doctors to examine organs and tissues without making large incisions, making them less invasive. Common applications include examining the gastrointestinal tract, respiratory system, and urinary tract. During an endoscopic procedure, the endoscope is inserted through natural openings, such as the mouth or rectum, or through small incisions. This approach enables the diagnosis and treatment of various conditions, including polyps, tumors, and inflammation, often allowing for immediate intervention.
