Techniques such as endoscopic mucosal resection and endoscopic submucosal dissection, are minimally invasive therapeutic techniques widely spread in human medicine, but unknown in veterinary medicine. This preliminary study compared 4 gastric submucosal injection solutions: hyaluronic acid, 10% glycerol, 6% starch and 0.9% physiological saline. By injecting 5 ml of each solution into ex vivo stomachs of pigs and subsequently assessing the elevation profile of each substance and comparing groups by means of the Student’s test with p<0.05. The initial diameter of the mucosal elevation showed no differences between groups and was around 4 cm. The maximum height was obtained by hyaluronic acid (10.3 mm). Finally, hyaluronic acid showed a longer permanence time (68 minutes). These preliminary results are promising because they allow the first approach of veterinary doctors to these techniques.
