Simulator training for endoscopic ultrasound

Endoscopic ultrasound (EUS) is one of the most challenging endoscopic procedures to learn and requires integration of both cognitive and endoscopic skills. EUS also is an important technology with a growing number of therapeutic applications. Despite its increasing role in managing gastrointestinal diseases, EUS technology remains largely limited to the confines in academic medical centers and tertiary referral centers because of issues concerning cost, equipment availability, efficiency of implementation, reimbursement, and most importantly, training. This article reviews the factors that are considered important for EUS training and discusses the use of various simulators and the potential role of these simulators in the future.
