Ultrasound gastroscopy time, which is related to the specific location of the disease, usually ranges from 15 minutes to 40 minutes. Ultrasound gastroscopy has always been an important means of auxiliary examination of diseases in gastroenterology, which can well determine the location of the disease, the scope of the lesion and the degree of invasion. For the diagnosis of general submucosal masses in the stomach and gastrointestinal tumors, the operation time of ultrasound gastroscopy is relatively short, usually around 15 to 25 minutes; however, for the diagnosis of hepatobiliary and pancreatic diseases, the operation time is relatively long, which may range from 20 to 40 minutes; when ultrasound endoscopy-guided puncture or contrast examination is required, the time may be extended accordingly. The operation time of ultrasound gastroscopy is not fixed, and patients are advised to evaluate it according to their actual situation.
