Transabdominal gastrointestinal (GI) ultrasound (US), despite its utility, is not a common procedure and underappreciated owing to its difficulty to perform. This study aimed to disseminate the skills of GIUS and assess the impact of our hands-on seminar. We annually held a half-day, hands-on seminar on GIUS at University of Toyama Hospital for physicians and sonographers from 2015 to 2017. Two months after the seminar, we inquired about clinical attainment by questionnaire. Out of 55 participants, 46 (83.6%) returned their questionnaires. Twenty participants (43.5%) reported that they had successfully diagnosed at least one GI disorder via GIUS since the seminar. Residual analyses stratified by the participants’ background showed that the novices, those having < 2 years’ experience in performing abdominal US, or no prior knowledge of GIUS, had significantly lower attainment rates (23.5% and 12.5%, respectively) than the others. Participants with 2 to 5 years’ experience in performing abdominal US or with some knowledge of GIUS had much higher rates of diagnosing GI disorders (54.5% and 57.9%, respectively). Nearly half of the participants had identified GI disorders using GIUS in 2 months following the training. The hands-on seminar was beneficial in disseminating these skills among a wide range of US operators.
