- Abstract: BACKGROUND/AIMS: The optimal training mode for linear array endoscopic ultrasonography (EUS) has not been established. Prior radial-scanning EUS training seems to improve subsequent linear array EUS learning. The objective of this randomized controlled trial was to evaluate its value in linear array EUS training. METHODS: In total, 18 freshman trainees conducted hands-on EUS operations on a live pig model. The training contents consisted of visualization and tracking of the pancreas and splanchnic vasculature and performing fine-needle aspiration of the body or tail of the pancreas and celiac plexus neurolysis through the stomach. The trainees were randomized into two groups: group A received linear array EUS training after receiving radial-scanning EUS training, whereas group B conducted linear array EUS training alone. Two teachers assessed the competence of each trainee using a scoring system and relevant parameters before and after the training process. RESULTS: Groups A and B showed significant improvement between the pretests and posttests in terms of diagnostic and interventional procedures. There was no intergroup difference in terms of improvement. CONCLUSIONS: Prior radial-scanning EUS training did not contribute to subsequent linear array EUS study performance in the pig stomach model; thus, this training mode may need to be changed.
