The aim of this study was to evaluate the effects of 10% copaiba oil in experimentally induced wounds in horses. Four wounds were made in the lumbar and metacarpal regions of eight adult horses. In the treatment group, the wounds received 10% copaiba oil and in the control group 0.9% sodium chloride, in the daily dressing for 21 days. The wounds were evaluated three, 7, 14, and 21 days postoperatively. No significant differences were observed between the groups. The mean lumbar wound contraction rates were 80.54% and 69.64%, for the control and treated groups, respectively. For the wounds in the metacarpal region, these averages were 44.15% and 52.48%, respectively. Under the experimental conditions of the present study, it is concluded that 10% copaiba oil has beneficial in wound healing in the equine species and suggest that copaiba oil can be used as a therapeutic possibility in equine wound therapy.
RESUMO.O presente relata a evisceração e posterior herniação inguinal de segmento de jejuno em equino submetido à orquiectomia. Um eqüino da raça Mangalarga Marchador, macho, 15 anos, foi encaminhado para realização de orquiectomia eletiva em haras no município de Alegre-ES. Após sedação e anestesia local, o paciente foi submetido ao procedimento cirúrgico. Decorridos 15 minutos, foi observado sangramento na região da bolsa escrotal, com visualização de tecido emergindo da ferida cirúrgica na bolsa escrotal direita. Após exame visual verificou-se tratar de porção do intestino delgado insinuandose pelo anel inguinal e ferida cirúrgica. Imediatamente o paciente foi submetido à laparotomia mediana à campo para redução da evisceração, sob anestesia geral intravenosa. O redução foi realizada com êxito, com sutura do anel inguinal externo direito. Decorridas seis horas do término da laparotomia, o paciente apresentou quadro clinico de abdômen agudo, e à palpação retal constatou-se presença de hérnia inguinal direita. Optou-se pela eutanásia do animal, por não haver um centro cirúrgico de grandes animais na região. Na necropsia foi verificado porção de jejuno insinuada no canal inguinal direito, com estrangulamento, apresentando-se com coloração esverdeada. A orquiectomia é uma técnica de execução relativamente simples, podendo ser realizada a campo pelo médico veterinário, porém, apresenta taxas de complicações elevadas, entre 20 a 38% dos casos, principalmente associados a erros de técnica cirúrgica. A evisceração intestinal pós-castração é considerada uma situação de emergência, exigindo uma conduta terapêutica rápida e eficiente. A sua ocorrência é rara, em torno de 0,2 a 2,6 % dos casos de orquiectomia. A palpação retal prévia à orquiectomia pode auxiliar na detecção de um anel inguinal interno dilatado ou qualquer alteração no mesmo, todavia esta prática não é realizada rotineiramente no pré-operatório de orquiectomia na espécie eqüina.

This case report describes an evisceration of a segment of the small intestine in a male, 15-years-old Mangalarga Marchador horse, which was submitted to elective orchiectomy in a stud farm in Alegre, ES, Brazil. Following sedation and local anesthesia, the patient was submitted to the surgical procedure. Fifteen minutes after the end of surgery, hemorrhage from the region of the scrotum was observed, with tissue protruding from the surgical wound in the right scrotal sac. Visual exam revealed that it was a segment of the small intestine protruding from the inguinal ring and surgical wound. The patient was immediately submitted to TIVA (total intravenous anesthesia) and an emergency median laparotomy was performed to reduce the evisceration. The procedure was carried out with success and the right external inguinal ring was sutured. Six hours after the second procedure, the patient presented clinical signs of acute
An omphalocele is a defect in the closure of the abdominal wall during the embryonic stage, preventing the return of some abdominal organs to the cavity. In stillborn animals, the involvement of the liver in the omphalocele has been reported. The aim of the present study is to report the success of a partial liver resection in a female bovine at two days of age which presented an omphalocele at birth. Surgical intervention was indicated to reduce and suture the abdominal wall. During the surgical procedure, the presence of hard, reddish tissue was noted inside the sac covered by the amniotic membrane, with characteristics consistent with hepatic parenchyma. Due to the impossibility of reducing the contents added to the suggestion of tissue infection, we elected to perform a partial resection. The histopathological examination confirmed that the resected tissue was of the hepatic parenchyma. Antibiotic and systemic anti-inflammatory therapies were performed post-surgery. Fifteen days after surgery, infection was detected at the surgical site in addition to abdominal wound dehiscence; surgical reintervention was performed. On physical examination, carried out 4 months after the second operation, the heifer presented normal development for the species. In conclusion, omphalocele may contain liver. Ectopic liver is an extremely rare condition. Surgical treatment in the presented case focused on umbilicus with exploration of the abdominal cavity appeared to be sufficient.
