Learning models for endoscopic ultrasonography in gastrointestinal endoscopy.

Area of Science:

• Gastrointestinal Endoscopy
• Medical Simulation
• Surgical Training

Background:

• Endoscopic ultrasonography (EUS) is a valuable diagnostic and therapeutic tool in gastrointestinal endoscopy.
• EUS necessitates specialized training due to its complex, operator-dependent nature, involving simultaneous endoscopic manipulation and ultrasonographic interpretation.
• Training on patients carries risks, including complications and diagnostic errors, highlighting the need for effective training alternatives.

Purpose of the Study:

• To review existing training models for endoscopic ultrasonography (EUS).
• To discuss the merits and limitations of various EUS training modalities.
• To emphasize the need for objective data on the efficacy of different EUS training models.

Main Methods:

• Review of current endoscopic ultrasonography (EUS) training models.
• Analysis of available training modalities including computer-based simulators, phantoms, ex vivo models, and live animal models.
• Assessment of the complementary, rather than competitive, value of these diverse training approaches.

Main Results:

• Current EUS training models possess unique advantages and disadvantages.
• The efficacy of these models is largely based on expert opinion, lacking objective comparative data.
• Existing models are considered complementary, suggesting a blended approach to EUS education.

Conclusions:

• A variety of models exist to facilitate endoscopic ultrasonography (EUS) training.
• Objective data is lacking to guide the selection and implementation of optimal EUS training strategies.
• Further research is required to objectively evaluate the effectiveness of different EUS training models on technical and clinical outcomes.
