ResumoDeiscência de sutura em anastomose intestinal é a principal complicação depois da cirurgia. Independentemente das melhorias nas técnicas cirúrgicas, os vazamentos na anastomose colônica freqüentemente ocorrem, resultando em alta morbidade e mortalidade, principalmente quando não é possível o preparo intestinal. Este trabalho teve como finalidade testar a submucosa de intestino delgado de suíno, conservada em glicerina, como protetor intraluminal (PIL) de anastomoses colônicas em cães. Foram operadas 16 cadelas adultas, com peso médio de 13,8 kg, que foram distribuídas em três grupos: um grupo controle com seis animais, e dois grupos de teste, sendo um composto de seis e o outro de quatro animais. A comparação entre os grupos teste e controle envolveu a mensuração do tempo cirúrgico e, no pós-operatório, avaliação clínica, colonoscópica e do bolo fecal. Não houve diferença significativa entre os tempos cirúrgicos. Não houve alteração clínica relevante em nenhum dos animais, nem diferença entre os exames colonoscópicos dos grupos controle e teste. Fundamentando-se nos resultados, conclui-se que o protetor intraluminal não causa danos à anastomose e este permanece fixado à submucosa por um período de três dias (período crítico da cicatrização colônica), podendo, então, ser considerado uma nova, fácil e barata técnica de proteção intraluminal.Palavras-chave: anastomose colônica, protetor intraluminal, cão. AbstractDehiscence of intestinal anastomosis remains a major complication after surgery. Despite improved surgical techniques leakage of colonic anastomosis frequently occurs, resulting in high morbidity and mortality, mainly when it is not possible to perform previous mechanical cleansing of the bowel. This work was designed to test glicerin preserved porcine small-intestine submucosa as an intracolonic bypass for protection of anastomosis in dogs. Sixteen female adult dogs, weighing 13,8 (average), were divided into three groups: A -control group, with six animals; B -test group, also with six dogs; C -test group, with four animals. Test and control groups were compared with basis on the following analysis: surgery time (minutes), post-surgical clinical signs, colonoscopy and fecal analysis. There was no significant difference between groups and the protector was kept in place for at least three days after surgery. With basis in these results, we have concluded that this intraluminal protector is a new, easy and unexpensive technique to be used in colonic anastomosis in dogs.Keywords: colonic anastomosis, intraluminal protection, dog.
Trichoblastoma is characterized as a benign cutaneous neoplasm that originates in the trichoblastic epithelium of the hair bulb. The present report describes the case of a 4-year-old cross breed neutered male cat that had a history of a slow, freely movable, ulcerated, slow growing, solitary cutaneous nodule located on the left scapular region. Histopathological evaluation showed neoplastic cells arranged in cohesive nests or palisades with eosinophilic and scant cytoplasm. Based on the microscopic findings, a diagnosis of trabecular trichoblastoma was made. The treatment of choice consisted of total surgical excision of the mass with safe surgical margins. Tumor recurrence was not observed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
