Endoscopic refers to procedures or techniques involving the use of an endoscope, a flexible or rigid instrument equipped with a camera and light, to visualise and access internal organs or cavities. This approach allows minimally invasive diagnosis and treatment, reducing patient recovery time and surgical risks compared to open surgery. A common application is gastrointestinal endoscopy, which can detect and manage conditions like ulcers or tumours, though complications such as perforation may occur.
