Background: Peritoneopericardial diaphragmatic hernia is a rare pathogenesis of congenital origin, which occurs due to a failure in the communication between the diaphragm and the pericardium during embryogenesis. Symptoms may be non-existent or non-specific, depending on the herniated organ involved and, in most cases, the diagnosis is incidental. Regarding the most indicated treatment, there are still divergences in the literature concerning the indication of conservative or surgical treatment. This study reports the case of a feline peritoneopericardial hernia, for which surgical correction was the treatment of choice. Case: A 3-month-old female kitten, no defined racial pattern, was referred to the Veterinary Hospital of the Federal Rural University of Pernambuco for treatment of a peritoneopericardial diaphragmatic hernia. This condition was diagnosed through radiographic examination after the patient having been submitted to pediatric castration and presented anesthetic complications in the transsurgery. Blood count, biochemical profile and Doppler echocardiogram were performed, which showed no significant changes. To obtain a better study and surgical planning, computed tomography was performed to observe the heart located cranially in the pericardial cavity. Caudally to the heart, hepatic parenchyma located in the pericardial cavity was observed; and hepatic vessels presenting slightly enlarged dimensions. These tomographic findings suggested peritoneopericardial diaphragmatic hernia; being the liver present in the pericardial cavity and signs of congestion in the hepatic parenchyma. Due to the likelihood of future worsening of the hernia, surgical correction was performed, with an abdominal midline incision in the preumbilical region to reposition the liver to its normal anatomy, followed by diaphragm reconstitution through a herniorrhaphy. After the surgical procedure, the patient was referred for observation in internment and, after 15 days, the skin sutures were removed. Complete correction of the hernial defect was observed on radiography performed 30 days after the surgical procedure. However, the examination showed the presence of deviation/ deformity in the topography of the sternum and costal cartilages, with slight cardiac displacement to the right hemithorax, suggesting the presence of pectus excavatum. Discussion: Peritoneopericardial diaphragmatic hernia is considered rare and, despite being one of the most common causes of congenital pericardial anomaly in felines, it has a low prevalence ranging from 0.06% to 1.45%. They are usually diagnosed from two years of age, with prevalence for older animals. However, due to having presented anesthetic changes, the patient of this case report could be diagnosed early. Among the most common organs that migrate to the thoracic cavity, the liver is the most commonly observed, which is also the hernia content of the present report. Peritoneopericardial hernia is often diagnosed through radiography and ultrasound, and these imaging tests proved to be sufficient for the diagnosis in this report. However, computed tomography was important for providing a better study of case and for the adoption of median celiotomy as a treatment. Associations with other malformations are described in the literature, with pectus excavatum being the most common and also observed in this report. Peritoneopericardial diaphragmatic hernia is a rare anomaly, rarely reported in the literature and with divergences regarding its treatment. The adoption of early surgical treatment performed in this report showed satisfactory evolution and the possibility of a favorable prognosis.

The use of medicinal plants as raw material for extracts production and pure substances isolation and subsequence development of new drugs represents a constantly growing area. However, some stages are indispensable before pharmacologically evaluating natural products such as medicines. Toxicity tests in mammalian cells are essential to initiate new drugs development or verify the substance's biocompatibility. Thus, we verified the toxicity of crude extracts and fractions with different polarities obtained from the leaves and stems of eight plant species. The toxic effect was evaluated on macrophages obtained from the bone marrow and peritoneal cavity of a Swiss webster mouse and J774 macrophages. G8 cell lineage. These macrophages were cultured in a 96-well plate, and the compounds were added at a concentration of 100 µg/mL for 24 hours. After this time, the supernatant was removed. The toxicity was evaluated for lactate dehydrogenase (LDH) release assay and the resazurin assay, which uses an indicator dye to measure oxidation-reduction reactions. The results showed a difference in the percentage of toxicity when comparing the same extract in different types of macrophages. This outcome indicates that these cells from different origins may exhibit different responses when exposed to the same natural compounds.


A utilização de plantas medicinais como matéria-prima para a produção de extratos e isolamento de substâncias puras para o desenvolvimento de novos fármacos representa uma área em constante crescimento. No entanto, existem processos a serem realizados antes de avaliar farmacologicamente produtos naturais como medicamentos. Os testes de toxicidade em células de mamíferos são fundamentais para iniciar o desenvolvimento de novas drogas ou verificar a biocompatibilidade de substâncias. Assim, verificamos a toxicidade de extratos brutos e frações com diferentes polaridades obtidos de folhas e caule de oito espécies de planta. Para comparar o efeito tóxico, os testes foram realizados em macrófagos obtidos da medula óssea e cavidade do peritônio de camundongo Swiss webster, bem como no macrófago da linhagem celular J774.G8. Esses macrófagos foram cultivados em placa de 96 poços e os compostos adicionados na concentração de 100 µg/mL por 24 horas. Após esse período o sobrenadante foi removido. A toxicidade foi avaliada pelos ensaios de detecção da enzima lactato-desidrogenase (LDH) e pelo ensaio de resazurina, que usa um corante indicador para medir as reações de oxidação-redução. Os resultados mostraram uma diferença na porcentagem de toxicidade quando comparamos o mesmo extrato em diferentes tipos de macrófagos. Este resultado indica que essas células de várias origens podem exibir respostas distintas quando expostas aos mesmos compostos naturais.

Os bloqueios locorregionais vêm sendo cada vez mais estudados na medicina veterinária, principalmente em pets não-convencionais e animais silvestres. O bloqueio do plano transverso do abdômen (TAP block) é uma técnica de anestesia locorregional capaz de promover anestesia e analgesia em regiões da pele, musculatura e peritônio parietal, as quais fazem parte da estratégia de analgesia multimodal. O objetivo deste trabalho é relatar o bloqueio do plano transverso em um coelho doméstico de quatro anos de idade submetido à mastectomia regional e ovariohisterectomia. Foram realizados dois pontos bilateralmente de bloqueio do espaço TAP guiado por ultrassom com 2mg/kg de bupivacaína a 0,25%, padronizando um volume total injetado de 2,4mL. Foram utilizados dexmedetomidina (5É¥g/kg) e midazolam (0,5mg/kg) por via intramuscular como medicação pré-anestésica, indução com isoflurano na máscara de oxigênio 100% e manutenção por anestesia inalatória com isoflurano. Os parâmetros fisiológicos mantiveram-se estáveis, sem necessidade de resgate analgésico, com extubação rápida e despertar tranquilo. Desta forma, conclui-se que o TAP block foi eficaz na analgesia para mastectomia regional e ovariohisterectomia como protocolo multimodal, aumentando o índice de segurança, além de ser de fácil execução mesmo com transdutores de baixa frequência.


The locoregional blocks have been increasingly studied in veterinary medicine, especially in non-conventional pets and wild animals. The transverse abdominis plane block (TAP block) is a locoregional anesthesia technique capable of promoting anesthesia and analgesia in the skin, muscle, and parietal peritoneum regions, which are is part of the multimodal analgesia strategy. This study aims to report the transverse plane block in a four-year-old domestic rabbit submitted to regional mastectomy and ovariohysterectomy. Two ultrasound-guided TAP space blocks were performed bilaterally with 2mg/kg of bupivacaine 0.25%, standardizing a total injected volume of 2.4mL. Dexmedetomidine (5É¥g/kg) and midazolam (0.5mg/kg) were used intramuscularly as pre-anesthetic medication, induction with isoflurane in a 100% oxygen mask, and maintenance by inhalation anesthesia with isoflurane. Physiological parameters remained stable, with no need for analgesic rescue, rapid extubation, and peaceful awakening. Thus, it is concluded that the TAP block was effective in analgesia for regional mastectomy and ovariohysterectomy as a multimodal protocol, increasing the safety index. Moreover, it is easy to perform even with low-frequency transducers.

Background: Cryptococcosis is an opportunistic, systemic mycotic disease caused by yeasts of genus Cryptococcus.Cryptococcus neoformans might cause serious public health problems, as they can be transmitted to humans, domesticand wild animals. In cats and dogs, the main site of infection is the upper lower respiratory tract, however, the infectioncan extend and affect other sites in the organism, however, the peritoneal manifestation of the disease is rare. Thus, thepresent work aims to report a case of cryptococcosis in a canine, mixed breed, female, adult, from the Metropolitan Regionof Belém, PA, Brazil.Case: A mixed breed dog, female, adult was admitted in a veterinary hospital at Belém, presenting abdominal discomfortand, after the clinical examination, emergency exploratory laparotomy was indicated, and it were observed disseminatedlesions in the abdominal cavity, with multiple nodules attached to the peritoneum and intestinal serosa and bladder, uterus,among other organs. Fragments from the surgical biopsy were fixed, and processed routinely according to the techniquesfor histological tissue processing. Histological examination revealed a predominance of granulomatous lesions in peritoneum and mesentery organs. It was observed a discrete inflammatory reaction of macrophages, epithelioid cells andgiant cells, many in phagocytosis of spherical or ovoid organisms, with a thick capsule and a clear perinuclear halo. Inthe PAS staining, the Cryptococcus conidia presented eosinophilic characteristics and some of them had the capsule welldemarcated, which was shown to be radiated.

ABSTRACT Purpose: To develop a reproducible training program model covering the steps of the extended totally extraperitoneal approach (e-tep) technique for correction of ventral or incisional hernia repair. Methods: Training sessions with surgeons in the laboratory using both porcine specimens and a new ethylene vinyl acetate (EVA) model simulating the operative steps of the e-tep technique. Students were interviewed and asked to answer a questionnaire pre and post the sessions to assess their performance and evaluated the course and model. Results: A total of 25 trained abdominal wall surgeons was evaluated at the end of the course. It was obtained a 100% satisfaction score of the training, as well as increased confidence levels up to 9 and 10 in all technical aspects of the surgery, having 96% of the surgeons performed a surgery under supervision of the proctors after the course. Conclusions: This training model is simple, effective, low cost, and replicable in guidance on the beginning of e-tep technique adoption, and performance. As a result, surgeons can get more confident and more able to perform surgeries employing this technique.

Background: Peritoneopericardial diaphragmatic hernia is a congenital defect characterized by an anomalous communication between the abdominal cavity and pericardial sac, which can lead to displacement of the abdominal viscera into the thoracic cavity. The occurrence in felines is higher among long-haired breeds, mainly the Persian breed, possibly based onan autosomal recessive inheritance. The diagnosis of PPDH is performed by means of chest radiography with or without contrast, in association with other imaging tests such as ultrasonography and echocardiography. Our objective in this study was to report the occurrence and macroscopic changes in a case of peritoneopericardial diaphragmatic hernia in a Persian feline. Case: A 9-year-old male Persian cat weighing 3.4 kg was referred to the HPET-Private Veterinary Clinic, Salvador, Bahia, with an history of weight loss and chronic intermittent vomiting during the preceding 6 months, with lateral decubitus and breathing difficulties. Ultrasonography revealed findings suggestive of an infiltrative process in the stomach and duodenum, enlarged gastric lymph nodes, and some nodular images indicating slight displacement of the liver. Chest radiography revealed a cardiac silhouette with markedly enlarged dimensions associated with a dorsal deviation of the terminal trachea, and echocardiography revealed a small amount of pericardial effusion. The patient showed initial clinical improvement after blood transfusion; however, after 2 days, he exhibited significant clinical worsening and was therefore euthanized with the owner's consent. Post mortem evaluation revealed partial herniation of the liver and gallbladder into the chest cavity through a diaphragmatic hernia ring. The heart was partially surrounded by the left medial lobe of the liver, which was displaced into the pericardial sac. Herniated hepatic lobes had an irregular capsular surface with evident lobulation and tension lipidosis. In the abdominal cavity, the remainder of the liver (right lateral and medial lobes) was observed to be slightly enlarged, with an irregular surface, diffusely reddish with intense evidence of the lobular pattern and white and firm multifocal areas (fibrosis). In the duodenum, close to the pylorus, there was a nodule measuring 2.8 x 2.5 x 1.0 cm, with a whitish and ulcerated surface. When cut, it was soft and exhibited a homogeneous, whitish compact surface. Histopathological examinationshowed marked proliferation of fibrous connective tissue, which for the most part separated the lobes by septa and surrounded the portal space (fibrosis), a marked diffuse chronic inflammatory infiltrate composed of lymphocytes and plasma cells. In addition, marked bile duct hyperplasia and multifocal areas of fatty degeneration (steatosis). Discussion: The diagnosis was based on the association of clinical and pathological findings. Considering the age and clinical signs presented by the patient in this report, as well as the presence of few radiographic signs that were indicative of PPDH, the first differential diagnosis thought was pericardial neoplasia. Peritoneopericardial diaphragmatic hernia in felines is always of congenital origin and may occur asymptomatically depending on the number and involvement of herniated viscera. In this case, the patient's diagnosis of peritoneopericardial hernia was a necropsy finding; the fact that in agreement with previous reports of high rates of incidental diagnoses reinforces the importance of performing necropsy for confirmation or diagnosis of unexpected pathologies. In the present case, peritoneopericardial diaphragmatic hernia in isolation may not have led to severe anemia that culminated in the patient's death. The anatomopathological findings were compatible with biliary cirrhosis and multifocal liver fibrosis, accompanied by the presence of anemia and consequent hypovolemia.

ABSTRACT: Urinary bladder damages leading to few viable bladder tissue available might demand a challenging reconstructive surgery. In this context, biomaterials are valid alternatives for bladder reconstruction. This study evaluated the bovine tunica albuginea fragment as graft material for cystoplasty in rats and honey-preserved implant viability.Thirty Wistar rats were assigned to two groups: (1) a test group (T) with a circular 1.0-cm-diameterbovine tunica albuginea graft application in the apex region by a continuous absorbable (Polyglactin 910 5-0) suture with stitching of all bladder layers and (2) a simulation group (S) in which animals underwent only partial cystectomy. In addition, each of these groups was further divided into three subgroups according to euthanasia period on post-surgery day 7, 15 and 30.Two animals had self-limiting hematuria at postsurgical period. At necropsy, frequent crystals and adhesion to the peritoneum were observed. At the histopathological evaluation, animals from the T group euthanized by 15th postoperative day had layers disorganization and initial muscle development, while T group rats euthanized by 30th postoperative day showed complete urothelization. Urothelization pattern was similar in both groups. Moreover, the muscular layer formation was present in both groups, but more evident in S group animals. Nevertheless, inflammatory infiltrate and neovascularization were remarkably more intense in T group rats.It might be concluded that bovine tunica albuginea graft was successful in repairing rats' bladder, being a good biomaterial option in reconstructive urinary vesicle surgery.


RESUMO: Lesões na vesícula urinária que culminem em pouco tecido vesical viável podem demandar cirurgias reconstrutivas desafiadoras. Neste contexto, biomateriais são alternativas válidas para a reconstrução da bexiga. O objetivo deste trabalho foi avaliar a túnica albugínea bovina como material para enxerto na cistoplastia em ratos, assim como a viabilidade deste implante preservado em mel. Trinta ratos Wistar foram divididos em dois grupos: (1) um grupo teste (T), no qual os animais foram submetidos a cistectomia parcial seguida de cistoplastia com aplicação do enxerto circular com 1,0cm de diâmetro de túnica albugínea bovina na região do ápice com sutura absorvível (Poliglactina 910 5-0) em padrão contínuo englobando todas as camadas da bexiga; e (2) um grupo simulação (S), cujos ratos realizaram apenas cistectomia parcial. Além disso, cada grupo foi posteriormente dividido em três subgrupos de acordo com a data de eutanásia no dia 7, 15 ou 30 de pós-operatório.Dois animais apresentaram hematúria autolimitante no período de observação pós-operatória. Na necrópsia, notaram-se cristais frequentes e aderências entre bexiga e peritônio. Na avaliação histopatológica, animais do grupo T eutanasiados com 15 dias de pós-operatório apresentavam camadas vesicais desorganizadas e formação de musculatura inicial na bexiga, enquanto aqueles eutanasiados com 30 dias de cirurgia mostraram urotelização completa. O padrão de urotelização foi semelhante nos dois grupos. Além disso, a formação da camada muscular esteve presente em ambos os grupos, porém mais evidente nos animais do grupo S. No entanto, o infiltrado inflamatório bem como a neovascularização foram notavelmente mais intensos nos ratos do grupo T.Pode-se concluir que o enxerto de túnica albugínea bovina foi bem sucedido no reparo da vesícula urinária de ratos, demonstrando ser uma boa opção de biomaterial para cirurgias reconstrutivas da vesícula urinária.

O objetivo deste trabalho foi relatar um caso de mesotelioma peritoneal epitelioide papilar em um bovino. Foi atendida uma vaca Gir, com dez anos de idade, apresentando taquicardia, taquipneia, 8% de desidratação, hipomotilidade ruminal, edema de barbela e aumento da circunferência abdominal bilateral ventral. Os achados de palpação consistiram na presença de múltiplos nódulos abdominais firmes, de tamanhos variados, localizados na parede abdominal e presença de grande quantidade de líquido intra-abdominal, confirmados pela ultrassonografia transretal. O líquido peritoneal coletado foi classificado como transudato modificado. Foi realizada laparotomia exploratória pelo flanco, identificando-se aproximadamente 150 litros de líquido peritoneal e múltiplos nódulos de coloração esbranquiçada, firmes, irregulares e difusos no peritônio e na superfície serosa de diferentes órgãos. O exame histopatológico dos fragmentos coletados por biopsia confirmou o diagnóstico de mesotelioma peritoneal classificado como sendo do tipo epitelioide papilar. A maioria dos casos de mesotelioma ocorre de forma incidiosa e sua manifestação clínica ocorre em quadros mais avançados, quando o prognóstico se torna desfavorável ao animal. A partir das condições encontradas no presente relato, foi indicada eutanásia do animal em razão do comprometimento do bem-estar.


The aim of this paper was to report a case of papillary epithelial mesothelioma of the peritoneal surface in a cattle. A ten-yearold Gir cow was examined on a rural property, presenting tachycardia, tachypnea, 8% dehydration, ruminal hypomotility submandibular edema and bilateral ventral abdominal enlargement. Rectal palpation showed multiple firm abdominal nodules, of varying sizes, located in the abdominal wall and the presence of large amounts of intra-abdominal fluid, confirmed by transrectal ultrasonography. The peritoneal fluid collected was classified as modified transudate. Exploratory laparotomy was performed along the flank, identifying approximately 150 liters of peritoneal fluid and multiple whitish-colored nodules, firm, irregular and diffuse on the peritoneum and on the serous surface of different organs. Histopathological examination of the biopsy pieces confirmed the diagnosis of peritoneal mesothelioma classified as papillary epithelioid type. Most cases of mesothelioma occur insidious, and its clinical manifestation occurs in more advanced cases, when the prognosis becomes unfavorable for the animal. Based on the conditions found in this report, euthanasia of the animal was indicated due to compromised well-being.

O objetivo deste trabalho é relatar o bloqueio do plano transverso em um felino macho de dois anos de idade submetido a mastectomia regional. Foram feitos dois pontos de bloqueio do espaço TAP guiado por ultrassom, em cada lado do abdômen: um na parte caudal da região abdominal média, cranial a crista ilíaca, e o outro ponto, caudal a última costela, com 0,5mg/kg de bupivacaína a 0,25% em cada ponto, padronizando um volume injetado de 0,6mL. Foi utilizado acepromazina (0,05mg/kg), petidina (3mg/kg), cetamina (2mg/kg) e midazolam (0,3mg/kg) como medicação pré-anestésica, indução com propofol (3mg/kg) e manutenção por anestesia inalatória com isoflurano. Conclui-se que o TAP block foi eficaz para mastectomia regional abdominal, com alto índice de segurança e de fácil execução com treinamento adequado, mesmo com transdutores de baixa frequência.


Locoregional blocks have been increasingly used in veterinary medicine. Blocking the transverse plane of the abdomen (TAP Block) is a technique of locoregional anesthesia, it is part of the multimodal analgesia strategy, capable of promoting anesthesia and analgesia in regions of skin, musculature and parietal peritoneum. The aim of this study is to report the transverse plane block in a two-year-old male cat undergoing regional mastectomy. Two ultrasound-guided TAP space block points were made on each side of the abdomen: one in the caudal part of the middle abodminal region, cranial to the iliac crest, and the other point, caudal to the last rib, with 0.5mg/kg of 0.25% bupivacaine at each point, standardizing an injected volume of 0.6mL. Acepromazine (0.05mg/kg), pethidine (3mg/kg), ketamine (2mg/kg) and midazolam (0.3mg/kg) were used as pre-anesthetic medication, induction with propofol (3mg/kg) and maintenance by inhalation anesthesia with isoflurane. It is concluded that the TAP block was effective for regional abdominal mastectomy, with a high safety index and easy to perform with adequate training, even with less frequent transducers.

Urinary bladder damages leading to few viable bladder tissue available might demand a challenging reconstructive surgery. In this context, biomaterials are valid alternatives for bladder reconstruction. This study evaluated the bovine tunica albuginea fragment as graft material for cystoplasty in rats and honey-preserved implant viability. Thirty Wistar rats were assigned to two groups: (1) a test group (T) with a circular 1.0-cm-diameterbovine tunica albuginea graft application in the apex region by a continuous absorbable (Polyglactin 910 5-0) suture with stitching of all bladder layers and (2) a simulation group (S) in which animals underwent only partial cystectomy. In addition, each of these groups was further divided into three subgroups according to euthanasia period on post-surgery day 7, 15 and 30. Two animals had self-limiting hematuria at postsurgical period. At necropsy, frequent crystals and adhesion to the peritoneum were observed. At the histopathological evaluation, animals from the T group euthanized by 15th postoperative day had layers disorganization and initial muscle development, while T group rats euthanized by 30th postoperative day showed complete urothelization. Urothelization pattern was similar in both groups. Moreover, the muscular layer formation was present in both groups, but more evident in S group animals. Nevertheless, inflammatory infiltrate and neovascularization were remarkably more intense in T group rats. It might be concluded that bovine tunica albuginea graft was successful in repairing rats bladder, being a good biomaterial option in reconstructive urinary vesicle surgery.(AU)


Lesões na vesícula urinária que culminem em pouco tecido vesical viável podem demandar cirurgias reconstrutivas desafiadoras. Neste contexto, biomateriais são alternativas válidas para a reconstrução da bexiga. O objetivo deste trabalho foi avaliar a túnica albugínea bovina como material para enxerto na cistoplastia em ratos, assim como a viabilidade deste implante preservado em mel. Trinta ratos Wistar foram divididos em dois grupos: (1) um grupo teste (T), no qual os animais foram submetidos a cistectomia parcial seguida de cistoplastia com aplicação do enxerto circular com 1,0cm de diâmetro de túnica albugínea bovina na região do ápice com sutura absorvível (Poliglactina 910 5-0) em padrão contínuo englobando todas as camadas da bexiga; e (2) um grupo simulação (S), cujos ratos realizaram apenas cistectomia parcial. Além disso, cada grupo foi posteriormente dividido em três subgrupos de acordo com a data de eutanásia no dia 7, 15 ou 30 de pós-operatório. Dois animais apresentaram hematúria autolimitante no período de observação pós-operatória. Na necrópsia, notaram-se cristais frequentes e aderências entre bexiga e peritônio. Na avaliação histopatológica, animais do grupo T eutanasiados com 15 dias de pós-operatório apresentavam camadas vesicais desorganizadas e formação de musculatura inicial na bexiga, enquanto aqueles eutanasiados com 30 dias de cirurgia mostraram urotelização completa. O padrão de urotelização foi semelhante nos dois grupos. Além disso, a formação da camada muscular esteve presente em ambos os grupos, porém mais evidente nos animais do grupo S. No entanto, o infiltrado inflamatório bem como a neovascularização foram notavelmente mais intensos nos ratos do grupo T. Pode-se concluir que o enxerto de túnica albugínea bovina foi bem sucedido no reparo da vesícula urinária de ratos, demonstrando ser uma boa opção de biomaterial para cirurgias reconstrutivas da vesícula urinária.(AU)

Resumo

A túnica vaginal possui características ideais para enxertia e já foi empregada na reparação de diversos tecidos, inclusive do diafragma pélvico. Objetivou-se avaliar a aplicabilidade da túnica vaginal como enxerto autógeno livre, em dupla camada, para a reparação do diafragma pélvico em 14 cães portadores de hérnia perineal, das quais, nove eram unilaterais e cinco, bilaterais. Após a orquiectomia, as túnicas de ambos os testículos foram coletadas, sobrepostas e fixadas entre si por meio de quatro pontos de reparo. Foi realizada abordagem ao saco herniário, inspeção, redução do conteúdo herniário, desbridamento muscular e síntese primária mediante sutura. O enxerto foi fixado à musculatura remanescente por meio de pontos simples separados e, posteriormente, encoberto pela sutura intradérmica e por síntese cutânea. Observações transoperatórias e, posteriormente, avaliações clínicas e ultrassonográficas, por período de um ano, permitiram sugerir que a túnica vaginal possui atributos ideais para a reparação do diafragma pélvico. Conclui-se que o enxerto autógeno livre de túnica vaginal, em dupla camada, é exequível e aplicável para o reparo do diafragma pélvico no tratamento da hérnia perineal em cães.(AU)


The tunica vaginalis has ideal characteristics for grafting and has already been used to repair several tissues, including the pelvic diaphragm. The aim of this study was to evaluate the applicability of the tunica vaginalis as a free double-layer autogenous graft to repair the pelvic diaphragm in 14 dogs with perineal hernia, of which, nine were unilateral and five, bilateral. After orchiectomy, the tunics of both testicles were collected, overlapped and fixed to each other by four repair points. The hernial sac was approached, followed by inspection, reduction of the hernia content, muscle debridement and primary synthesis through suture. The graft was attached to the remaining musculature by simple interrupted stitches and later hidden by intradermal suture and cutaneous synthesis. Intraoperative observations and, later, clinical and sonographic evaluations over a one-year period, allow to suggest that the tunica vaginalis has ideal attributes for the pelvic diaphragm repair. It is concluded that the autogenous graft-free of tunica vaginalis in double layer is feasible and applicable in order to repair the pelvic diaphragm in the perineal hernia treatment in dogs.(AU)

Resumo

Com o objetivo de promover, por meio de acesso único e com o uso de endoscópio flexível, ampla exploração da cavidade peritoneal de equinos em estação, foi concebida uma cânula laparoscópica para dar sustentação ao endoscópio e possibilitar o acesso sob visualização. O procedimento foi realizado a partir da fossa paralombar. Após pequena incisão cutânea, o endoscópio foi inserido na cânula e os músculos e o peritônio foram divulsionados mediante rotação da cânula. Logo depois da perfuração do peritônio, foi realizada a exploração da cavidade e a identificação das estruturas. Em seguida à exploração do lado ipsilateral ao acesso, realizou-se a transposição do conjunto cânula/endoscópio ventralmente à porção caudal do cólon descendente, seguida de exploração do lado contralateral. Concluída a técnica, foi executado, para fins de comparação, o mesmo procedimento por meio da fossa paralombar contralateral. Foi possível a transposição do conjunto cânula/endoscópio para o lado contralateral ao acesso em todos os procedimentos. Também foi possível a identificação da maioria das estruturas abdominais tanto pelo acesso esquerdo quanto pelo direito. A abordagem por acesso único mostrou-se viável para a exploração ampla da cavidade peritoneal, demonstrando ser uma alternativa à técnica laparoscópica convencional.(AU)


A laparoscopic cannula was designed to support a single access approach with a flexible endoscope for the wide exploration of the peritoneal cavity of standing horses. It provides support to the endoscope and allows access to the peritoneal cavity with a visual aid. This procedure was performed through the paralumbar fossa. After a small cutaneous incision, the endoscope was inserted into the cannula, and the muscles and peritoneum were divulsed through the rotation of the cannula. After the peritoneal perforation, cavity exploration and identification of structures were performed. After the exploration of the ipsilateral side of the access, the cannula/endoscope was transposed ventrally to the caudal portion of the descending colon; this was followed by the exploration of the contralateral side. Once this process was completed, the same procedure was performed through the contralateral paralumbar fossa for comparison. It was possible to transpose the cannula/endoscope set to the contralateral access side in all procedures. Further, it was possible to identify most of the abdominal structures in both the left and right access. This single access approach proved to be feasible for the extensive exploration of the peritoneal cavity, thereby indicating it can be an alternative to the conventional laparoscopic technique.(AU)

Resumo

Xenarthras (Mammalia, Dasypodidae) das espécies Dasypus novemcinctus e Euphractus sexcinctus tiveram sua anatomia científica estudada em relação à topografia dos intestinos delgado e grosso, suas relações peritoniais, morfologia externa e irrigação. Medidas dos diferentes segmentos intestinais e do número de vasos a eles destinados foram tomadas para fins comparativos. O método previu: fixação (formol 7%); injeção de látex; dissecação e fotodocumentação. Espacialmente, embora os intestinos sejam fixados por dupla membrana peritoneal, como em outros vertebrados, nestes a serosa conectou o duodeno, o jejuno, o íleo e os cólons em um único ligamento fixado no dorso do animal. Duodeno e pâncreas, intraperitoniais, como o reto, fixaram-se nas pelves maior e menor, respectivamente e dorsalmente. Vasos derivados do tronco celíaco mesentérico e da aorta percorreram o interior do mesoduodeno, do mesentério comum, do mesocólon e do mesorreto, estando estes, ao longo de seus trajetos, relacionados às cadeias linfonodulares intestinais. O modelo de rotação peritoneal, a morfologia externa, bem como o modelo de vascularização intestinal, foram interpretados como basais, diferindo dos vertebrados recentes, conforme o suporte literário.(AU)


Xenarthras (Mammalia, Dasypodidae) of the species Dasypus novemcinctus and Euphractus sexcinctus had their scientific anatomy studied in relation to the topography of the small and large intestines, their peritoneal relationships, external morphology and irrigation. Measurements of the different intestinal segments and the number of vessels destined for them were taken for comparative purposes. The method predicted: fixation (7% formaldehyde); latex injection; dissection and photo documentation. Spatially, the intestines, although fixed by a double peritoneal membrane, as in other vertebrates, in these, the serosa connected the duodenum, jejunum, ileum, and the colon in a single ligament fixed to the animal's back. Duodenum and pancreas, intraperitoneal, like the rectum, were fixed in the major and minor pelvis respectively and dorsally. Vessels derived from the mesenteric celiac trunk and the aorta traveled through the interior of the mesoduodenum, common mesentery, mesocolon and mesoride, being related to the lymph node chains along their pathways. The peritoneal rotation model, the external morphology as well as the model of intestinal vascularization were interpreted as basal, differing from recent vertebrates, according to literary support.(AU)

Background: Intestinal obstruction by a foreign body is a common occurrence in domestic animals, needing the attention of veterinarians and owners, given that a serious complication of this condition is intestinal rupture, with consequentperitonitis. Perforating objects are the ones most often associated with rupture, but any object that obstructs the intestinaltract, if not removed properly, can lead to intestinal rupture, generating a poor prognosis. This article reports a case ofintestinal rupture caused by a non-perforating foreign body in a dog.Case: A 1-year-old Chow-Chow dog was taken by its owner to the Portal Pet private clinic, with a history of foreignbody ingestion and emesis. The owner reported that he took the animal to veterinary care in another establishment on theday he noticed vomiting, with no other abnormality being detected. An injectable medication was administered, but theowner did not know what it was, and the dog was discharged. After 15 days, the owner sought care at the clinic initiallymentioned, due to the persistence of emesis, in addition to the onset of diarrhea and apparent apathy. On physical examination, the dog was apathetic, with pale mucosa and pain on abdominal palpation. A firm structure was felt, located in theepigastric region, compatible with a foreign body. The dog was referred for hospitalization and an abdominal ultrasoundwas requested, in addition to blood samples for hematological and serum biochemical tests (urea, creatinine, alanineaminotransferase, and alkaline phosphatase). Serology for parvovirus was also performed. The blood count revealedleukopenia (4,800 thousand/mm3) and biochemical analysis showed an increase in alkaline phosphatase (895.5 U/l). Theresults for parvovirus were negative. Ultrasonography confirmed the presence of a foreign body. The animal was referred...
