What is the name of the medical equipment for anal examination?

Generally from the anus, it is much less painful than gastroscopy. Hello; Ultrasonic endoscope (EUS) is an advanced medical equipment which combines ultrasound and endoscope. It places a miniature high-frequency ultrasonic probe at the front end of the endoscope. When the endoscope enters the gastric cavity, it can directly observe the shape of the cavity and scan it in real time, so as to obtain the histological characteristics of the pipeline walls at all levels and the ultrasonic images of the surrounding organs. The main advantages of EUS are to determine the nature of submucosal lesions in the gastrointestinal tract, to judge the depth and scope of invasion of malignant tumors in the digestive tract, and to diagnose pancreatic system diseases. Ultrasonic endoscope is different from ordinary gastroscope. There is an ultrasonic probe at the front end of the ultrasonic endoscope. This small probe can be sent into the stomach cavity by gastroscope for ultrasonic detection, and can see the lesions in the esophagus and deep stomach. Therefore, endoscopic ultrasonography is of great value in the diagnosis and treatment of esophageal and gastric protuberant lesions. In addition, endoscopic ultrasound has other uses. For example, endoscopic ultrasonography can help doctors judge the depth of invasion of gastric cancer and the metastasis of surrounding lymph nodes, and can distinguish whether gastric ulcer is benign or malignant.
