Avaliação gastroscópica de equídeos provenientes de apreensão

Abstract

Equine Gastric Ulcer Syndrome (EGUS) refers to the formation of ulcers in the caudal portion of the esophagus, stomach and cranial portion of the duodenum. The diagnosis is made by means of an endoscopic evaluation, which makes it possible to determine the location, classification and severity of the lesion. This study aimed to evaluate, through endoscopic examination, the occurrence of esophageal, gastric and duodenal changes, of equidae seized by the Municipality of Uberlândia (PMU) and sent to the large animal sector of HV-UFU. As a justification, it is used the fact that the occurrence of SUGE is still little reported in animals in this group. It was expected to find a high number of ulcerations in this group of animals because they generally do not have good living conditions, often suffering from mistreatment, having previously been subjected to excessive work activity associated with physical stress, inadequate food handling with low quality food nutrition and forced fasting. Eighteen animals were treated, with no manifestation of clinical signs for EGUS. The equines were submitted to endoscopic examination, after a 24-hour water and food fast and sedation protocol, by administering xylazine hydrochloride 10%, intravenously, in the dose of 0.5 to 1.0 mg / kg. For evaluation, a Portascope endoscope - Model 1800LG200 was used. During the examination, the lesions found were assessed for occurrence and anatomical location, quantified and classified according to the number and degree of severity, using a score (0-5). The results were analyzed using Kruskal-Wallis, Sepearman and Dunn statistical tests, with the aid of the GraphPad InStat ™ program (GraphPad Software, version 3.01, 1998). All animals evaluated were asymptomatic, but because they were apprehended animals, they were usually in situations of malnutrition or with some concomitant illness, sometimes active, chronic and / or healed, it was then possible to observe that 66.7% (12/18) presented some type of gastric ulceration, with margo plicatus being the most affected region. It was concluded that EGUS can be found in its different numerical and severity degrees in apprehended animals suffering from mistreatment, excessive working hours and low quality of feeding, even when they do not present clinical symptoms, indicating that attention and care is needed at this group of animals, since these factors negatively influence the appearance of gastric ulcerations.
