What Is an Endoscopic Resection?

The technique of inspecting and treating intuitively using a speculum that can be put into a human body cavity. Divided into non-invasive and traumatic. The former refers to the direct insertion of an endoscope to check the cavity (such as the digestive tract, respiratory tract, and urinary tract) that is in communication with the outside world; the latter is fed into the endoscope through an incision to check the closed body cavity (such as the thorax, Abdominal cavity, joint cavity, etc.).

Chinese name

Endoscope

Types of

Metal rigid tube type, fiber light guide type, etc.

Shape

Same as fiber optic endoscope

Effect

Similar to electronic endoscope

Endoscopes are divided into three types according to the structure: metal rigid tube type, fiber light guide type, and electronic camera type. The electronic camera uses microelectronic technology to take pictures and develop images. Its appearance is the same as that of the fiber optic endoscope. By connecting the eyepieces of various endoscopes with the connectors of the micro camera, the image can be displayed on the TV screen for observation, and the effect is similar to that of the electronic endoscope. Endoscopes are divided into digestive tract, urogenital tract, respiratory tract, body cavity, and head organ endoscope according to their uses.

Fibrous stomach and duodenoscopy are the most widely used endoscopes in clinical practice. Metal rigid tube colonoscopy, also known as sigmoidoscopy, is commonly used for the examination of sigmoid colon and rectal lesions, or for specimens taken for pathology or pathogen examination. Before the examination, the patient needs a clean enema, and the examination is performed at the knee and elbow. The appearance of the fiber colonoscope is the same as that of the fiber gastroscope, and there are three specifications: long, medium and short. Endoscopes used in the respiratory system include bronchoscopes, thoracoscopy, and mediastinoscopy. Metal rigid tube bronchoscope is only used to remove foreign bodies in children's trachea. The widely used fiberoptic bronchoscope is similar in appearance to the fiberscope, but has a short body. Except for those with severe cardiopulmonary insufficiency, most people can do this test. It is a simple and safe method for the diagnosis and treatment of bronchial, pulmonary, and pleural diseases. The positive rate of lung cancer diagnosis is high. The positive rate of diagnosis of tuberculosis, especially bronchial tuberculosis, is higher. Can also be used to rescue critically ill patients. Thoracoscopy is used to diagnose chest and lung conditions. Endoscopes are placed in the urinary system (bladder, ureter, renal pelvis) to diagnose and treat urinary system diseases. The hysteroscope is a metal rigid tube type. The subject will take the lithotomy position after emptying the bladder. Anesthesia is not required. Mental stress can be injected with sedative drugs before surgery. Laparoscopes are mostly metal rigid tubes and must be used under sterile conditions to avoid causing abdominal infections. Ophthalmoscope is also called ophthalmoscope. In addition to directly observing the optic nerve, retinal and other lesions, it can also determine the degree of hypertension and arteriosclerosis through the changes in the fundus blood vessels, and the status of cerebral edema according to the optic nerve papillary situation.

1. Handle the endoscope gently, and hold the objective lens to prevent the mirror from bending and falling.

2. Fine mirrors cannot be put together with other instruments, and nothing can be placed on the mirrors to prevent the mirrors from being bent and twisted and cannot be inserted into the sheath and damaged.

3. There should be a special box for storing the mirror, which should be kept by a special person and stored in a special cabinet. Observe the sharpness of the mirror carefully before storing it to ensure the next use.

4. After the mirror accidentally falls, you should immediately connect the optical cable and observe the object through the eyepiece to check whether the damage is caused. If damage occurs, it should be immediately sent to the relevant department for repair.

1. Soak the wiped endoscope in a multi-enzyme washing solution. The time is according to the instructions.

2. Immediately after use, thoroughly wash and dry with running water.

3. Brush the shaft, bend, and lumen of the instrument thoroughly with a soft bristle brush. Be careful not to scratch the mirror surface when brushing.

4. Thoroughly clean the components of the endoscope. The lumen should be thoroughly washed with a high-pressure water gun. The removable parts must be disassembled and cleaned and cleaned with an ultrasonic cleaner for 5 to 10 minutes.

5. Endoscopes or endoscope components suitable for pressure steam sterilization should be pressure steam sterilized. Pay attention to the temperature and time selection according to the requirements of the endoscope instructions.

6. Endoscopes and accessories that cannot be pressure steam sterilized can be sterilized by soaking in 2% alkaline glutaraldehyde for 10 hours.

7. When disinfecting and sterilizing with disinfectant, instruments with joints should be fully opened, and instruments with lumen should be fully filled with disinfectant. ^[1]
