Percutaneous ruminostomy guided by rumenoscopy: study in an experimental model in bovine fetus.

BACKGROUND: Endosurgery is a surgical subspecialty that has been widely used in production animals, because it enables good visualization of abdominal organs and the diagnosis and treatment of several conditions in a minimally invasive manner, while preserving the animal's well-being and causing a lower impact on animal production. Rumenostomy is one of the most common surgical procedures in ruminants. This procedure is used to allow access to the rumen for various purposes, especially nutritional and therapeutic studies, and it can be performed either in a conventional way or in a minimally invasive video-assisted manner. Another possibility of access to ruminants is through the rumenoscopy technique. The objective of this study is to describe a minimally invasive technique for rumenostomy using an endoscope, working on a bovine fetal corpse as an experimental model. RESULTS: The execution of the endoscopy-guided rumenostomy technique was simple and did not present major difficulties. The endoscope, its lighting and air pump, and the decubitus used provided a good anatomical visualization of the rumen, and it was possible to evaluate several regions of the organ. The mean duration of the procedure was 11.15 min. CONCLUSIONS: The endoscopic rumenostomy technique using anatomical pieces of calves was shown to be feasible. It was performed in a simple and efficient way, particularly regarding the premise of preserving the animal's well-being, due to its minimally invasive nature.

Integrative approach to a patient following rumenotomy - case report / [Abordagem integrativa ao paciente submetido à ruminotomia - relato de caso]

Concern with antimicrobial resistance in animal production systems increases the interest toward integrative therapies. The objective of the present report was to report an integrative approach to a goat undergoing rumenotomy. A goat with ruminal acidosis underwent rumenotomy, corrective rumen suture, moxibustion, and treatment of the surgical wound (TFO) with sugar. In the first twenty days, acupuncture was performed on ST36, indirect moxibustion on Sp6 and CV8, and TFO with antibiotic ointment and sugar. The wound contracted 2cm, there was gradual return of ruminal dynamics, and moderate pain. Acupuncture continued from D21 to D50 on Yin tang, BL13, BL20, BL23, and BL22. Although there was drainage of ruminal fluid, the wound contracted 4cm during this period, pain was absent, and ruminal dynamics normal. During the last thirty days, the acupuncture technique surround the dragon was used and BL13 point needled, with complete closure of the wound. The TFO from D21 was performed solely with sugar. During treatment, there was modulation of the inflammatory response, with formation of granulation tissue and neovascularization. On D84, fibrinogen was 100mg/dL. The authors conclude that the use of sugar, acupuncture, and moxibustion contributed to return of normal ruminal motility, wound contraction, and complete tissue reepithelization.(AU)

A preocupação com a resistência antimicrobiana nos sistemas de produção animal aumenta o interesse pelas terapias integrativas. Objetiva-se relatar a abordagem integrativa ao paciente caprino submetido à ruminotomia. Uma cabra com acidose ruminal foi submetida à ruminotomia, ruminorrafia, moxabustão, acupuntura e tratamento da ferida operatória (TFO) com açúcar. Nos primeiros vinte dias realizou-se acupuntura em ST36, moxa indireta em Sp6 e CV8, TFO com pomada antibiótica e açúcar. A ferida contraiu 2cm, houve retorno gradual da dinâmica ruminal e dor moderada. A acupuntura continuou de D21 a D50 em Yin tang, BL13, BL20, BL23 e BL22. Apesar da ferida drenar fluido ruminal teve contração de 4cm nesse período, ausência de dor e retorno fisiológico da dinâmica ruminal. Nos últimos trinta dias foi realizada a técnica de acupuntura cercar o dragão e punturou-se o ponto BL13, com fechamento completo da ferida. O TFO a partir do D21 foi realizado somente com açúcar. Durante tratamento houve modulação da resposta inflamatória com formação de tecido de granulação e neoangiogênesse, o D84 revelou fibrinogênio 100mg/dL. Conclui-se que a utilização do açúcar, acupuntura e moxabustão contribuíram para o retorno fisiológico da motilidade ruminal, contração da ferida e completa reepitelização tecidual.(AU)

Rib fracture in buffalo with ruminal cannula

Background: Buffalos are very rustic animals that are adapted to adverse conditions, but the lack of adequate managementcan increase the susceptibility of these animals to several diseases. Rib fracture in this species is usually related to mineraldeficiency and complications resulting from unappropriated management. Rib fractures in ruminants are rarely diagnosedand usually present conservative treatment; however, cases with presence of contaminated wounds require extra attention.The objective of this work was to report an atypical case of open fracture of the last rib in a buffalo with ruminal cannula,describing the case from diagnosis to surgical treatment.Case: An adult female water buffalo (Bubalus bubalis) that was well fed and receiving minerals, with implantation ofa ruminal cannula, presented a lesion around the ruminal cannula, with increasing volume, exudation, and myiasis. Thegeneral parameters and behavior of the animal were apparently normal. The animal presented normal appetite and respiration and good physical condition and nutritional state, with pain reaction to the touch in the region of the lesion andtheir adjacencies; it presented no claudication and reluctance to remain in left lateral decubitus, and no discomfort. Theclinical inspection of the cutaneous lesion showed an oblique-type fracture in the body of the last left rib, with exposedbone in the lumbar region and extremity exposed to the ruminal cannula, already presenting necrosis. The region wascleaned, removing larvae (myiasis) for better exposition of the fracture; in the following day...(AU)
