The difference between e-gastroscopy and ultrasound gastroscopy mainly lies in the different locations and purposes of observation. Electronic gastroscopy is mainly used for direct observation of mucosal diseases to do the examination, such as gastric ulcer, chronic gastritis, superficial gastric erosion, etc.; electronic gastroscopy can observe the esophagus, stomach, duodenum mucosa and other parts of the lesions, generally can not see the lesions of the submucosa. And ultrasound gastroscopy is based on the gastroscope and the use of ultrasound probe scanner, is generally used to observe the submucosal material, direct use of gastroscopy can not observe the lesions. Ultrasound gastroscopy can help clarify the nature of the submucosal mass. In addition, ultrasound endoscopy can assist in the diagnosis of pancreatic tumors, abdominal masses and other conditions. It is recommended to choose a regular hospital for examination, and if necessary, guided puncture can be performed through ultrasound endoscopy to determine the nature of the lesion.
