The aim of this study was to evaluate the use and postoperative complications of a T-shaped latex cannula surgically placed in the ileum of ten 18-month-old steers, with an initial mean body weight of 281.50kg. The steers were anesthetized, positioned in left lateral recumbency, and the distal small intestine was exteriorized through a right paralumbar incision. A T-latex cannula was placed into the lumen of the ileum, 10-cm from the ileocecal fold on the antimesenteric surface, and sutured to the ileum. The stem of the cannula was exteriorized in the flank, 15cm ventral to the transverse process of lumbar vertebrae and at 8cm cranial to the ventral comissure of the first surgical abdominal incision, providing good stability and security. Established cannulas were well tolerated and caused minimal fibrous tissue reaction at the site of fistulation and, in 80% of the steers, samples of ileal digesta could be collected throughout a period from 122 to 305 (171,87 ± 58,71) days. Hence, this simple T-shaped latex cannula provides a good tool for obtaining samples from the ileum. KEY-WORDS: Ileostomy. Intestinal cannulation. Intestine. Ileum. Cattle
Cânulas flexíveis de látex em forma de .T., foram implantadas no íleo de dez bovinos machos com 18 meses de idade e peso médio de 281,50kg, visando avaliar o uso deste material e descrever as complicações pós-operatórias observadas. As cânulas foram implantadas na face antimesentérica do íleo, a 10cm da prega ileocecal. As hastes das cânulas foram exteriorizadas no flanco direito, a aproximadamente 15cm ventral aos processos transversos das vértebras lombares e a 8cm cranial à comissura ventral da primeira incisão abdominal, provendo boa estabilidade e segurança às preparações cirúrgicas. As cânulas foram bem toleradas pelos bovinos, provocando fibrose discreta no local da fístula e permaneceram implantadas de modo satisfatório em 80% dos animais, permitindo colheitas de conteúdo intestinal num período variável de 122 a 305 (171,87 ± 58,71) dias, sendo úteis na obtenção de digesta ileal.

The goals of this study were to evaluate if hemoglobin played a role as adjuvant in experimental peritonitis in horses and could cause clinical and haematological alterations that could be used for diagnosis and prognosis of cases of peritonitis. Fifteen adult horses were randomly divided into 5 equal groups, which were injected intraperitoneally with the following suspension: GI: 1x109 colony-forming units (CFU) of E. coli diluted in 500 mL of 0.9% saline solution plus 5 g of hemoglobin; GII: 1x109 CFU of B. fragilis diluted in 500 mL of 0.9% saline plus 5 g of hemoglobin; GIII: 1x109 CFU of E. coli in combination with 1x109 CFU of B. fragilis diluted in 500 ml of 0.9% of saline plus 5 g of hemoglobin; GIV: 500 mL of 0.9% saline plus 5 g of hemoglobin and GV: 500 mL of 0.9% saline. Leukopenia with neutropenia was observed in GI and GIII and a significant increase in plasma fibrinogen concentration occurred in horses of GI. There was a significant increase in total nucleated cell count in peritoneal fluid in horses of GI, GII, GIII and GIV. Fever, tachycardia, tachypnea, abdominal wall sensibility and tension, diarrhoea, colic, and decreased borborygmi sounds were the most frequent clinical signs observed in horses of GI, GII, GIII and GIV. In conclusion, hemoglobin was able to cause chemical peritonitis in horses, it had an adjuvant effect when associated t
