Since the endoscopy technology has been widely used in cosmetic surgery, plastic surgeons have reached unprecedented heights in the field of plastic and cosmetic surgery. Endoscopy technology, involving plastic and cosmetic surgery, began in the mid-1990s and became popular in Europe and America after its many advantages were shown. In recent years, a few hospitals have also carried out endoscopic-guided surgeries. Its rapid development is entirely due to its obvious advantages. Traditional surgeries that require large incisions can now be done with only tiny wounds with the assistance of endoscopes and special surgical instruments. This not only reduces the trauma of surgery but also increases its accuracy and safety, making patients more willing to accept the procedure.
Medical endoscopes are optical instruments made up of a cold light source lens, fiber optic cable, image transmission system, screen display system, etc., which can expand the surgical field of view. The prominent feature of using endoscopy technology is that the incisions are small, the scars are not obvious, the postoperative reactions are mild, and the bleeding, bruising, and swelling time can be greatly reduced. Recovery is also faster than traditional surgery, which conforms to the requirements of aesthetic surgery that leaves no trace.
Fiber gastroscope, duodenoscope, and gastroscope are the most widely used endoscopes in clinical practice. Metal hard tube colonoscopes, also known as sigmoidoscopes, are commonly used for examining sigmoid colon and rectal lesions or taking samples for pathological or pathogenic examinations. Before the examination, the patient needs to have a clean enema and be examined in a knee-elbow position. The fiber colonoscope has the same shape as the fiber gastroscopes and comes in three sizes: long, medium, and short. The endoscopes used in the respiratory system include bronchoscopes, thoracoscopes, and mediastinoscopes. Metal hard tube tracheoscopes are only used to remove foreign bodies from children's tracheas. The widely used fiber bronchoscope is similar to the fiber gastroscope but has a slender appearance. In addition to severely impaired heart and lung function, most people can undergo this examination, making it a more convenient and safe method for diagnosing and treating bronchial, pulmonary, and pleural diseases.
Endoscopy technology is an important method for detecting and diagnosing early-stage colorectal cancer. In the past 30 years, with the widespread use and improvement of endoscopy technology and the development of various endoscopic instruments, the detection and diagnosis of early colorectal cancer have become possible.
Magnifying endoscopy (also known as enlarging endoscopy): can amplify mucosal images more than 100 times and repeat colonic cancer pit opening changes.
Staining endoscopy: commonly uses brilliant scarlet and methylene blue as chromogenic agents (generally sprayed with 1% methylene blue solution). Inflammatory lesions, small polyps, and polypoid changes can be diagnosed based on the distribution of the pigments. The combination of magnifying endoscopy and staining endoscopy can observe early-stage colorectal cancer mucosal glandular duct openings in groove or irregular shapes, which is helpful for early diagnosis.
Endoscopic ultrasonography: tumors' location, range, and depth can be determined through endoscopic ultrasonography. Generally, it is believed that the accuracy of endoscopic ultrasonography for determining the depth of tumors is over 80%, and it can also determine whether there is metastasis in lymph nodes and distant organs. This helps to improve the detection rate and preoperative diagnosis rate of early colorectal cancer, which is of great significance for improving the prognosis of colorectal cancer.
CT colonoscope: This is an imaging technique that uses CT to obtain data from colon angles, that is, two-dimensional and three-dimensional data.
In recent years, due to the clinical application of staining endoscopy and magnifying endoscopy, the use of EMR or EMPR for the complete removal of early-stage colorectal cancer, and the significant increase in the detection rate of early colorectal cancer, internal medicine treatment can lead to a cure, significantly improving the five-year survival rate of colorectal cancer.
