Endoscopy (or fibroscopy) can visualize the hollow organs: the bronchi, the inside of the digestive tract, the urinary tract, the female genital tract but also cavities like the peritoneum (in which are all the organs of the abdomen), the mediastinum (space between the two lungs), etc.
Endoscopy is often performed under general anesthesia, or under neuroleptanalgesia (rather superficial and short anesthesia). It is necessary to be fasting and not having smoked for several hours. Hospitalization is usually short term. It is sometimes necessary to stop certain treatments such as anticoagulants for example before undergoing this examination.
The principle of endoscopy
To perform an endoscopy, an endoscope (or fiberscope) consisting of a tiny camera is used at the end of an optical fiber in a flexible tube and connected to a computer that scans the captured images, displays them on a monitor and records them .
The doctor who performs the examination sees on a screen the organs or lesions. He advances the endoscope; he can stop to observe a lesion, he can perform a biopsy, that is to say, take a small piece of tumor or tissue that seems abnormal, thanks to the clips inserted with the camera. At the same time, the doctor can also treat certain lesions like some cysts by removing them completely.
