Hiperplasia endometrial cística em uma coelha-doméstica (Oryctolagus cuniculus domesticus) / Cystic endometrial hyperplasia in a domestic rabbit (Oryctolagus cuniculus domesticus)

Background: Cystic endometrial hyperplasia is a hormone-dependent disease induced by systemic increase in progesteronethat can occur in several domestic species, such as the rabbit. This disease may be associated with sex steroid hormones,especially progesterone, and may be asymptomatic, and it is diagnosed using complementary imaging tests such as totalabdominal ultrasound. However, surgical excisional biopsy with histopathological tissue analysis is the gold standard. Thisstudy reports a case of asymptomatic cystic endometrial hyperplasia in a female Miniature Lion Lop rabbit (Oryctolaguscuniculus domesticus) treated with therapeutic ovariohysterectomy.Case: A domestic, adult, female Miniature Lion Lop rabbit (Oryctolagus cuniculus domesticus), aged approximately 5 yearsand weighing 3.2 kg, was referred to specialized care to undergo ovariohysterectomy, an elective procedure. The tutor onlyreported the occurrence of a single episode of vulvar secretion more than 2 years ago, treated with antibiotics, with remissionof clinical signs. In the intraoperative period after celiotomy, the uterine horn and uterine body showed a significant increasein volume, with abnormal color changes and tissue consistency; however, both changes were clinically asymptomatic. Subsequently, biopsy was performed during the ovariohysterectomy procedure. The excised uterus and ovaries were placed in 10%formalin and histopathologically analyzed. The macroscopic histopathological examination of the sectioned tissue revealed aslight amount of brownish fluid inside the uterine horns, in addition to multiple cystic areas in the uterine mucosa. Microscopicexamination revealed marked hyperplasia of well-differentiated endometrial epithelial cells, occasionally forming cystic structuresof different sizes. Moderate congestion, mild multifocal hemorrhage, and mild multifocal inflammatory infiltrate in the lamina...

Uso de técnica laparoscópica vídeo-assistida com dois portais para cirurgia de piometria em uma cadela / The use of laparoscopy video-assisted with two portals for treatment of pyometra in a bitch

A piometria é uma das afecções mais comuns na rotina clínica de pequenos animais, com maior incidência de ocorrência em fêmeas com idade acima de 9 anos. O tratamento mais seguro e mais eficaz para correção da piometria é a ovariosalpingo-histerectomia. Recentemente, estão sendo implementadas novas técnicas cirúrgicas minimamente invasivas como alternativas a ovariosalpingo-histerectomia realizada através de laparotomia, como a ovariosalpingo-histerectomia laparoscópica em uma cadela com piometria. Uma cadela de 3 anos de idade e histórico de uso repetido de contraceptivos, foi encaminhada para o setor de cirúrgica para realização de ovariossalpingohisterectomia para tratamento de piometria. Devido ás vantagens conhecidas dos procedimentos laparoscópicos e ao porte adequado do animal que possibilita a fácil manipulação laparoscópica das estruturas abdominais, foi escolhida a técnica laparoscópica vídeo assistida utilizando 2 portais, em que não encontramos complicações transoperatórias, e cadela se recuperou rapidamente(AU)

The pyometria is one of the most common disorders in small animals clinical practice, with higher incidence in females over 9 years. The safest and more effective treatment for pyometra is ovariohisterectomy. New minimal invasive surgical techniques have been implemented as alternatives to ovariohisterectomy and performed by laparotomy, such as laparoscopic ovariohisterectomy or video assisted by the advantages they have compared to conventional surgeries. The objective of this study is to describe the technique of laparoscopic ovariohisterectomy in a bitch with pyometria. A 3-years-old-dog with a history of repeated use of contraceptives was sent to the surgery sector for ovariohisterectomy to treat the pyometra. It was used a two portals video-assisted technique because of the known advantages of laparoscopic abdominal structures, there was no trans-operative was no trans-operative complications, and dog had a quick recover(AU)
