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.
