Basic Scanning Methods of Radial EUS

  • Kazuya Akahoshi


Essentially the premedication for EUS is the same as for conventional endoscopy (EGD, TCS etc.). Standard EUS was performed on an outpatient basis, with the patient under conscious sedation. In our institute, each patient was sedated with an intravenous injection of flunitrazepam (0.2–0.4 mg) and pethidine (35 mg). The insertion of the echoendoscope is in the same way as conventional endoscopy, i.e. under forward-viewing endoscopic image guidance (Fig. 3.1) [1].
