The aim of this pilot test was to test a new self-locking resorbable implant for hilum occlusion during a video-assisted thoracoscopic lung lobectomy in a surviving pig model. Once the thoracic cavity was assessed and structures identified, the right middle lobe and its respective hilum were exposed. The implant was introduced with a semiclosed loop through a working channel and positioned around the pulmonary lobe. Occlusion was performed with a conventional Crile forceps and a laparoscopic Kelly forceps. Lobe section was done with laparoscopic Metzenbaum scissors and tissue removal through the dorsal access. No signs of pneumothorax or bleeding were observed during a 60-day follow-up. Necropsy findings showed minimal pleuritis in caudal access and in the lobar stump. A granulomatous formation was found around a dense, amorphous material, which was identified as remains of a small part of the implant. Histopathological findings showed signs of a chronic healing process without other alterations. The resorbable implant LigaTie appears to exhibit similar handling and application characteristics during surgery as nonsurgical tie wraps. The resorbable implant avoids the uncontrolled substances not suitable for implants of conventional ties. The results of this pilot test suggested the resorbable implant's mechanical properties provided effective tissue support to complete the healing of the pulmonary hilum.

A 2-year-old female mixed-breed cat weighing 2.7 kg presented with recurrent rectal prolapse. The following report describes its treatment by laparoscopic-assisted incisional colopexy using two portals. The procedure was effective and without trans- or postoperative complications. Recurrent prolapses did not recur in the 2 months of postoperative observation.

RESUMO:Afecções dentárias são as principais enfermidades da cavidade oral de equinos, podendo estar relacionadas à dieta e ao escore corporal. Objetivou-se neste estudo avaliar as desordens dentárias, escore corporal e o manejo alimentar que cavalos de tração da região metropolitana de Curitiba apresentam, e verificar se há correlação entre eles. Foram avaliados 64 equinos, através de exame clínico e avaliação odontológica. Destes, 52 apresentaram escore corporal adequado, 54 apresentaram apenas uma alteração dentária e 27 apresentaram duas ou mais, sendo a presença de caninos longos a alteração mais encontrada, observada em 20 cavalos. Pontas de esmalte, ganchos, rampas, presença do dente primeiro pré-molar, fraturas dentárias, cálculos dentários, degraus e ausência de dentes foram outras alterações encontradas. Os principais componentes da dieta desses cavalos de tração são: pasto, capim picado, farelo de trigo, milho e restos de comida. Através do Teste de Correlação de Spearman verificou-se ausência de significância estatística na correlação entre a dieta, as alterações dentárias e o escore corporal. Conclui-se com este estudo que os cavalos carroceiros da região metropolitana de Curitiba apresentam baixa prevalência de problemas dentários, os quais não são influenciados pela dieta e não acarretam em prejuízos ao seu escore corporal.

The aim of this study was to evaluate these disorders, the body condition and feeding management of draft horses from Curitiba metropolitan areas, checking if there is a correlation between them. Sixty-four horses were evaluated by clinical examination and dental evaluation. From those 52 had adequate body condition, fifty-four had only one tooth affection and 27 had two or more. The presence of wolf teeth the most frequent alteration, observed in 20 horses. Enamel ends, hooks, ramps, presence of the first premolar tooth, fractures, dental calculi, steps and missing teeth were other alterations. The main components of the diet were grass, chopped grass, wheat bran, and corn and food debris. Using the Spearman's correlation test there was no statistically significance between diet, dental change and body condition. This study concludes that the draft horses from Curitiba metropolitan areas have a low prevalence of dental problems, which are not influenced by diet and do not result in damage to body condition.
