GOMEZ, Martín Alonso. Utility of a model for the training of endoscopic ultrasound. Rev Col Gastroenterol [online]. 2007, vol.22, n.2, pp.104-110. ISSN 0120-9957.

The endoscopic ultrasound is a technique that is being used more every day; unfortunately it is performed by less than 1% of the gastroenterologists in Colombia. Among several factors that could explain this, are: the lack of training centers, the long learning curve and the complications associated to these procedures. The training models have been very useful in the learning process of mucosectomy and endoscopic ultrasound. Nevertheless, the models described so far are expensive and require a high technology resource, which is usually not available in the training centers. For these reasons we have created an inexpensive model, easy to make and very useful to learn EUS Objective: To create a model that allows the teaching and learning of the radial and linear endoscopic ultrasound. Materials and methods: The following materials are necessary to build up the model: Plastic recipient of 5 liters, a pig stomach, 400 gr of jelly, 2 liters of water, latex gloves #2, peas #4, carrots #1, grapes #4. The total cost of the elements is approximately 5 dollars. The 400gr of jelly are placed in the plastic recipient and then a liter of cold water is poured in it until the jelly dissolves completely, then a liter of hot (pre-boiled water) is added and when it is getting solidified, the stomach is placed in the center of the recipient and around it the other elements. Results: The first day begins with the radial endosonography; the equipment is introduced in the stomach and the goal for the first class is to learn the 5 layers of the gastric wall, then the student learns how to differentiate a lesion that is inside the wall from an extrinsic one. The next step is to identify the targets around the stomach, learning how to differentiate hipoecoic from hiperecoic structures. Then the linear equipment is introduced, learning how to take biopsies. Conclusion: This new model is very useful in the learning process of the radial and linear endoscopic ultrasound. It can be made at a very low cost and with very simple elements, in a home made setting that allows its utility at any service of endoscopy in the world.
