Description and Executability of a Novel Pre-tied Mini Ligature (Miniloop) in Laparocopic Ovariectomy in Cats

Background: Ovariectomy(OVE) and ovariohysterectomy (OVH) are the most performed surgical procedures in Veterinary Medicine. In videosurgery, both in stray animals at sterilization campaigns and in the increasing demand of tutors to perform the technique. Laparoscopy results in reduced tissue damage, due to minimal organ manipulation and surgical access hemostasis can be performed by several methods, such as electro-coagulation, clips, and intra and extracorporeal ligatures. A pre-tied ligature system, or endoloop, is a haemostatic technique comprised of a slipknot and knot pusher, which is inserted into the abdominal cavity through one of the laparoscopic ports. The aim of this study was to describe a novel OVE technique in cats, in which haemostasis was performed using miniloop, aimed at reducing the number of ports needed for knot tying.Material, Methods & Results: Ten healthy not spayed female cats, aged 6 months to 5 years, were selected for this study. They were submitted to an OVE using miniloop as haemostasis method. Access to the peritoneal cavity was through two 5 mm ports on the midline of the ventral abdomen, 5 cm apart, with one immediately caudal to the umbilical scar and the other in between the last pair of teats. The first trocar was inserted at the caudal incision using the Hasson technique and a 5 mm zero-degree optics attached to a camera was introduced

Use of nylon clamp, catgut and emasculator to prevent hemostasy in ovariectomy in mares / Emprego da abraçadeira de náilon, do categute e do emasculador na hemostasia preventiva de ovariectomia em éguas

The ovariectomy is used in the equine species for inhibiting the estrus, treating cysts, ovarian tumors, improving the animal´s performance and favoring the conviviality in group. In this procedure, it´s fundamental to perform the preventive hemostasy of the vessels from the ovarian pedicle to avoid the death of the animal due to hemorrhage. In this study, the efficacy of the nylon clamp was evaluated as an hemostatic method for ovariectomy in mares and the cost of the procedure was estimated, compared to the use of catgut and the emasculator. 18 equine females, without defined breed, clinically healthy, between 300 kg and 400 kg of corporal weight and between three and eight years of age were used. The animals were allotted in three groups of six animals each one (Fab, Fcg, Fem). The nylon

A ovariectomia é empregada na espécie eqüina para incluir o estro, tratar de cistos e tumores ovarianos, melhorar o desempenho do animal e favorecer o convívio em grupo. Nesse procedimento é fundamental realizar a hemostasia preventiva dos vasos que compõem o pedículo ovariano para se evitar o óbito do animal por hemorragia. Avaliou-se, neste estudo, a eficácia da abraçadeira de náilon como método hemostático na ovariectomia em éguas e estimou-se o custo do procedimento, comparado ao uso do categute e do emasculador. Utilizaram-se dezoito fêmeas eqüinas, sem raça definida, clinicamente saudável, com peso variando entre 300 kg a 400 kg e na faixa etária entre três a oito anos. Os animais foram divididos em três grupos de seis animais cada (Fab, Fcg, Fem). No grupo Fab, para realizar a hemostasia do pedículo ovariano, empregou-se a abraçadeira de náilon, no grupo Fcg o fio categute e no grupo Fem o emasculador. Avaliaram-se os resultados através de exames clínicos, hematológicos e possível ocorrência de complicações trans e pós-operatórias. Os três métodos utilizados promoveram hemostasia preventiva satisfatória. No entanto, a abraçadeira de náilon apresentou menor custo, diminuiu o tempo do procedimento cirúrgico e permitiu o não-registro de intercorrências no pós-operatório. PALAVRAS-CHAVE: Abraçadeira de náilon, eqüino, hemostasia, ovariectomia, ovário.

Aspectos epidemiológicos e ocorrência de fixação dorsal de patela em bovinos

A fixação dorsal de patela é uma síndrome observada em grandes animais, ocorrendo em bovinos, uni ou bilateralmente, em ambos os sexos e em diferentes idades e raças. O objetivo deste estudo foi avaliar a ocorrência de possíveis fatores de risco relacionados à enfermidade em bovinos submetidos a diferentes manejos. O estudo foi realizado em trinta fazendas de criação de bovinos entre janeiro de1998 a agosto de2002, em 41 animais enfermos. Usou-se um questionário constando dados como: resenha,estágio de lactação, de prenhez e grau de parentesco entre os animais, topografia e tipo de solo. Estabeleceram-se escores corporais correlacionando o estado físico e diferentes situações dos animais. Encontraram-se 56% de animais mestiços na faixa etária entre cinco e nove anos coma enfermidade, com maior ocorrência em fêmeas entre dois e três anos e em touros na estação reprodutiva. A enfermidade era mais evidente em animais com escore corporal baixo, em lactação, prenhes e durante a seca. Casos de recuperação espontânea ocorreram no período chuvoso. Observaram-se 76,6% de animais afetados em pastagens de cerrado e 23,4%em pastagens de solo com maior fertilidade. Os índices encontrados sugerem que vários fatores de risco podem contribuir ou estar associados no desencadeamento da fixação dorsal de patela em bovinos. PALAVRAS-CHAVE: Bovino, sistema locomotor, fixação dorsal de patela, fator
