Endoscopic procedures are minimally invasive techniques used to visualize and treat conditions within the body. They involve the use of an endoscope, a flexible tube equipped with a camera and light, which is inserted through natural openings or small incisions. This allows doctors to examine organs such as the stomach, intestines, and lungs without the need for large surgical cuts. These procedures can be diagnostic, helping to identify issues like ulcers or tumors, or therapeutic, allowing for treatments such as biopsies or polyp removal. Endoscopy is valued for its ability to reduce recovery time and minimize discomfort compared to traditional surgery.
