A brief history of endoscopic ultrasound

In 1980, the United States first reported that the combination of ultrasound and ordinary endoscopy was successful in animal experiments, which initiated the clinical application of endoscopic ultrasound technology. Since then, endoscopic ultrasound instruments have been continuously developed and improved. After more than 20 years of clinical practice, the technology of endoscopic ultrasound is becoming more and more mature, and its application scope is also expanding. The emergence of endoscopic ultrasound has made the endoscopic technology realize the rapid development. Endoscopic ultrasonography can pipe wall on the digestive tract mucosa lesions properties of crops grown in the differential diagnosis, and preoperative staging of gastrointestinal tumor, determine its invasion depth and scope, the identification of benign and malignant ulcer, and diagnosis of pancreatic biliary system cancer, especially for high precision, small tumor diagnosis on chronic pancreatitis, etc is superior to other imaging studies. In addition, the application of fine needle aspiration biopsy under endoscopic ultrasound can also significantly improve the diagnosis rate of lesions. At present, interventional diagnosis and treatment under endoscopic ultrasound is one of the hot spots of endoscopic technology at home and abroad.
