This model is useful for the training of basic NOTES procedures, such as establishing transgastric and transcolonic access, peritoneal exploration, and tissue biopsy. For the more advanced ‘digestivist’, the EASIER can facilitate organ resection (cholecystectomy, distal pancreatectomy, liver lobe resection, hysterectomy, oophorectomy) or gastrointestinal anastomosis techniques (gastrojejunostomy, partial gastrectomy, colectomy). Multiple gastrotomies or colotomies can be performed in a single model. To facilitate multiple participants during gastrotomy or colotomy, each procedure ends by closing the perforation with a variety of closure devices.

In addition to the endoscopic view, surgical procedures can be observed through the clear acrylic cover. By removing the lid, a direct assessment of tissue incision, resection, and clip application can be undertaken by gross inspection of the the surgical site.

In contrast to using live animals for NOTES training, the use of ex-vivo specimens obtained from the meat industry, does not involve ethical concerns and is not subject to IRB approval.

For the simulation of laparoscopy or hybrid NOTES procedures a special cover with laparoscopic ports is used instead of the clear lid. This permits the use of commercially available laparoscopic instruments.
