ABSTRACT
Tumores gástricos em animais domésticos são raros, e a literatura pertinente é escassa. Em humanos, esse tumor representa 80% dos tumores mesenquimais do trato digestivo, sendo mais comum no estômago (70%). Indivíduos de meia-idade e idosos, principalmente do gênero masculino, são os mais afetados, e o diagnosticado é feito com base em suas manifestações clínicas associadas à morfologia celular típica e à imuno-histoquímica positiva. O presente trabalho objetiva descrever um sarcoma gástrico em cão, assim como o diagnóstico, o tratamento cirúrgico e o pós-cirúrgico do animal. Foi atendido no Hospital Veterinário da Universidade Metropolitana de Santos (Unimes) um cão macho, SRD, 10 anos, 8,3kg, castrado, com bom estado geral, com queixa de emese há um ano. Na ultrassonografia abdominal foi observada a presença de uma formação arredondada no estômago que media 3,20 x 2,61cm, localizada na região epigástrica em contiguidade com a parede. O cão foi submetido a endoscopia gástrica, em que se observou a presença de uma massa arredondada na região pilórica, confirmada na laparotomia e na gastrotomia. O tumor retirado foi enviado para avaliação anatomopatológica, e os achados foram compatíveis com sarcoma estromal gástrico.(AU)
Gastric tumors in domestic animals are rare and the literature is scarce. In humans this tumor represents 80% of mesenchymal tumors of the digestive tract, most commonly in the stomach (70%). Affected individuals are middle-aged and elderly, especially males, diagnosed from its clinical manifestations in association with typical cell morphology and positive immunohistochemistry. The aim of this report was to describe a gastric sarcoma in a dog, as well as the diagnosis, surgical and post surgical treatment. The experiment was conducted in the Veterinary Hospital of the Metropolitan University of Santos (UNIMES) on a male dog, SRD, 10 years old, 8.3kg, castrated, in a good general condition, with complaint of emesis for year. In the abdominal ultrasound exam we observed the presence of a round formation in the stomach which measured 3.20 x 2.61cm, located in the epigastric region contiguous with the wall. The dog was submitted to gastric endoscopy, in which the presence of a rounded mass in the pyloric region was observed, and laparotomy and gastrostomy were performed. The removed tumor was sent for pathologic evaluation, where the findings were compatible with gastric stromal sarcoma.(AU)

O diagnóstico da úlcera gastroesofágica (UGE) é fundamental para que se tente a recuperação dos afetados, entretanto há grande dificuldade na sua realização de forma precisa. Modernos endoscópios são ferramentas importantes nesse sentido e podem ser usados para determinar em que fase da criação a ulceração ocorre. A bactéria Helicobacter tem sido associada à UGE e gerado perdas econômicas. Tendo em vista que poucos trabalhos têm sido realizados para identificação do problema precocemente, este estudo teve como objetivo detectar as lesões relacionando-as, ou não, com a bactéria Helicobacter spp., mediante análises macroscópica e histopatológica de amostras colhidas por meio da gastroscopia. Foram utilizados 20 animais de ambos os sexos, pesando entre 22 e 26kg e com 65 dias de idade. O aparelho utilizado foi um gastrovideoscópio da marca Karl Storz, modelo 1380NKS. Foram colhidas amostras das regiões anatômicas aglandular (quadrilátero esofágico) e glandular (cárdica, fúndica e pilórica) para o teste ultrarrápido da urease e para as avaliações histopatológicas e imuno-histoquímicas. Onze animais apresentaram lesões na região aglandular à endoscopia, e microscopicamente 15 animais apresentaram paraqueratose. Em 18 animais, foram observadas alterações em pelo menos uma das três regiões glandulares. As lesões foram maiores na região cárdica, seguida da antral e da fúndica. Em relação ao teste ultrarrápido da urease, sete animais foram negativos nas quatro regiões, e 13 positivos em pelo menos uma delas. Em relação à imuno-histoquímica (IHQ), 10 animais foram negativos em todas as regiões e 10 foram positivos em pelo menos uma delas. Os achados pré-ulcerativos não demonstraram relação com o Helicobacter spp., que apresenta caráter saprofítico e oportunista confirmado pela sua imunomarcação em áreas sem lesão...
Gastroesophageal ulcer (GEU) diagnosis is fundamental for the treatment and recovery of the affected animal stock. GEU is a condition affecting animals, resulting in depletion of animal stock and subsequent economic losses. Helicobacter spp. have been associated with GEU. Modern endoscopes are important for detecting the stage of the breeding process at which the ulceration occurs. However, few studies regarding early detection of GEU have been conducted. Therefore, we aimed to identify whether GEU lesions were related to Helicobacter spp. infection, using gastroscopy as a diagnostic technique for macroscopic and histopathological analyses. Twenty piglets (both male and female) with a mean age of 65 days were included (weight, 22-26 kg). We used a Karl Storz Gastrovideoscope (model 1380NKS). Samples from nonglandular and glandular (cardia, fundus, and pylorus) regions were collected for the ultra-rapid urease test and for histopathological and immunohistochemical (IHC) evaluations. Eleven animals showed macroscopic lesions in the nonglandular region during endoscopy, and 15 animals showed parakeratosis on histological analysis. Lesions in at least 1 glandular region were observed in 18 animals. The lesions were bigger in the cardiac region, followed by those in the antrum and the fundus. Regarding the ultra-rapid urease test, 7 animals were negative in all 4 regions and 13 were positive in at least 1 region. On IHC, 10 animals were negative in all 4 regions and 10 were positive in at least 1 region. However, pre-ulcerative findings were not correlated with Helicobacter spp. infection in the present study. The positive IHC findings for Helicobacter spp in regions without ulcerative lesions suggest its saprophytic and opportunistic nature...

Prevalence, distribution and density of gastric helicobacter colonization were determined in 50 healthy dogs, characterizing the macroscopic and microcospic aspects of their mucosa. Helicobacter prevalence was 96 percent, with greater distribution in the gastric fundus and body. Although the presence of macroscopic alterations was high (58 percent), it was characterized as mild due to the predominance of less severe ones (65.5 percent). High prevalence of mostly monoclear cell infriltate (64.7 percent) was noted. Association between the presence of helicobacter and macro and microscopic alterations was not observed

A seven months old, tiger shovelnose catfish was referred to the veterinary medical teaching hospital of the college of veterinary medicine, Konkuk university because of suspecting a foreign body in the stomach. By physical and radiologic examinations, the catfish revealed abdominal enlargement, vomiting, inactivity and radiopaque foreign bodies in the stomach. Under general anesthesia with dilute isoflurane solution, celiotomy was performed. Stomach was atonic, and three foreign bodies were palpated in the stomach. In this process, three stones came out through mouth. Abdominal muscles were closed with a simple continuous suture pattern, and skin was closed with a simple mattress suture pattern. Sutured site was covered with glue and mucous taken from allogenic skin. On the second day after surgery, the patient recovered to normal condition, showing increased appetite and activity.
