Background:In the last years the number of exotic company animals has been increased, and the demand for neutering services for these animals has become greater. By the author’s knowledge, there are no records of elective ovariectomy in domestic swine (Sus scrofa domesticus). The current paper reports a case of elective laparoscopic ovariectomy in a domestic swine (Sus scrofa domesticus).Case:A 4-month-old domestic swine (Sus scrofa domesticus), weighing 45 kg was referred to elective video-laparoscopic ovariectomy at the Veterinary Clinics Hospital of the Federal University of Rio Grande do Sul (HCV - UFRGS). Physical examination and laboratory tests, including hemogram and biochemistry (alanine aminotransferase - ALT, serum albumin and creatinine), were within normal range for the species. Ketamine hydrochloride (Cetamin®) 10 mg.kg-1, xylazine hydrochloride (Xilazin®) 2 mg.kg-1, and midazolam (Midazolam®) 0.5 mg.kg-1 were administered intramuscularly (IM) as pre-anesthetic medication. The anesthetic induction was performed with intravenous (IV) propofol (Propovan®) and anesthesia was maintained with isoflurane (Isoforine®) diluted in O2 by a universal vaporizer with a partial gas rebreathing anesthetic system. Throughout the procedure, were monitoring constantly the invasive blood pressure (IBP), electrocardiogram (ECG) in lead II, peripheral arterial saturation with O2 (SpO2), end-tidal carbon dioxide concentration (ETCO2), and esophageal temperature. The abdominal cavity was accessed through the insertion of three portals (one of 10 mm of diameter and other two of 5 mm of diameter). The cavity was inflated with medicinal CO2 until the pressure of 10 mmHg was achieved. The uterine body and ovaries were identified. The right ovary was suspended and, by a bipolar clamp, the ovarian vessels were occluded through electrocoagulation in three distinct locations with approximately 0,5 cm between themselves, and cut off. The right ovary was removed from the cavity. An identic maneuver was used for the realization of the surgical steps and removal of the left ovary. By the end, the cavity was deflated and the cannulas were removed. The abdominal wall was sutured with Sultan pattern with 3-0 polyglycolic acid thread, and the skin was sutured with simple interrupted suture with 3-0 nylon monofilament. The post-operative evaluations were subjective and fitting with the patient's behavior. The patient didn't show any clinical signs of pain, discomfort and returned to its usual eating habits on the second day after the procedure. No signs of infection, dehiscence, cicatrization retard or other complications were observed in the surgical wound. The stitches were removed after seven days.Discussion: This case report shows the applicability of the video-laparoscopic ovariectomy technique by three portals in other species than dogs and cats, and serves as bibliographic support to the veterinary endosurgery field. Based on previous studies, it has been concluded that minimally invasive procedures represent the most beneficial sterilization methods to the patient due to its diagnostical and surgical capacity, as well as minor surgical trauma and shorter recovery time. The most common indication for the video-laparoscopic technique in veterinary routine is the elective sterilization. Pyometra, urinary incontinence and weight gain are complications that are not diagnosed more frequently after ovariectomy when compared to ovariohysterectomy. The laparoscopic ovariectomy is a viable technique to be applied to the swine, with the most difficult aspect being the anatomical peculiarities of the animal.

Fishing cats (Prionailurus viverrinus) are small (6–15 kg) spotted cats from dispersed areas of Southeast Asia found mostly in wetland habitats. They are classified by the International Union for Conservation of Nature (IUCN) as endangered, with a decreasing population, due to habitat loss and degradation. Few studies have been done on applying assisted breeding techniques to the species, although the birth of a live kitten after IVF/embryo transfer (ET) has been reported (2006 Theriogenology 66, 1518–1524). Here, we describe the birth of a live fishing cat kitten using the technique of laparoscopic intratubal AI. A ten-year-old female who had served previously as an oocyte donor (5×) following gonadotropin treatment was administered a total of 5 IU of porcine FSH (Sioux Biochemical, Sioux City, Iowa) over 4 days (1×/day) followed by 10 IU of porcine LH on the fifth day. At approximately 28 h after LH treatment, the ovaries/oviduct were accessed by a laparoscopic technique comparable to that used for oviducal embryo transfer (ibid.). To deposit semen into the left oviduct, a 16-guage thin-wall trocar/needle was inserted into the abdominal cavity on the right side, approximately 1 cm lateral to the midline and approximately 2 to 3 cm below the umbilicus. A 14-cm open-end tom cat catheter was inserted into the 16-guage cannula (blunt) and the catheter tip was positioned underneath the fimbria overlaying the ovary. Then, a 50-mm length of 30-guage polytetrafluoroethylene (PTFE) thin-wall tubing containing approximately 30 μL of freshly collected semen was threaded through the catheter and the sample was expelled with positive pressure from a threaded-plunger 1-mL syringe. The left ovary contained 7 to 8 preovulatory (3–4 mm) follicles, 4 of which were manually ruptured immediately after deposition of semen with a 22-guage needle inserted through the 16-guage cannula. Then, with the 16-guage trocar/cannula in the same position (on the right side), the tip was redirected towards the right ovary and approximately 30 μL of semen was deposited underneath the fimbria as described above. The right ovary presented with 5 to 6 preovulatory (3–4 mm) follicles, 2 of which were punctured with the 22-guage needle after insemination. No ovulations were present on either ovary. The semen used for insemination was a fresh sample collected by electroejaculation from a 9-year-old male. The raw sperm concentration was 220 million mL–1, with 70% motility. The number of motile sperm deposited per oviduct was estimated to be approximately 4.6 million. The female was anesthetized 51 days later and radiography was done to determine her pregnancy status. A single fetus was present, so she was moved from an outdoor pen into a large indoor holding pen to allow for video-monitoring during the remainder of gestation. On Day 70, early signs of labour were observed and an elective Caesarean section was done approximately 4 h later. A live, healthy male kitten weighing 204 g was delivered. One year later, gonadotropin treatment/AI were repeated on the same pair. At approximately 30 h post-LH treatment, preovulatory follicles were present, but fewer than the previous treatment (5–6 total). Two fresh ovulation sites were seen on the left ovary. Pregnancy was not established. A reason for the failure was not apparent, unless it was age related.

Background: Manatees are the most endangered aquatic mammals in Brazil. The current conservation scenario, together with their biological characteristics, raises concern with the future of this species. Pyothorax, also known as septic pleural effusion or pleural empyema, is characterized by the accumulation of a septic purulent exudate within the pleural space. Although this infection often has a multifactorial etiology, it is most commonly associated with respiratory tract disorders and trauma. Here, we report a case of pyothorax in a Antillean manatee (Trichechus manatus) held in captivity for acclimatization in Brazil.Case: A young, male Antillean manatee, aged 4 years and 11 months, measuring 227 cm in total length, and weighing 258 kg was held in captivity for acclimatization (natural environment) in Porto de Pedras in the State of Alagoas, Brazil. The animal died in February 2013 and was sent for necropsy at the CMA/ICMBio laboratory. The study was developed with authorisation from the Ethics Committee on Animal Use (License number 020/2009) and under the license SISBIO/ICMBio number 20685-1. Externally, the carcass of the animal showed swelling and bulging of the right antimere and purulent secretion from the right nostril. After external examination, a window was opened in the layers of skin, fat, and muscles from the level of the anus to the navel. Subsequently, the abdominal cavity was opened for inspecting the internal organs. The subcutaneous muscles had a slightly friable, swollen, and pale texture, in addition to petechial hemorrhage, suffusions, and marked edema of the subcutaneous tissue. The right hemidiaphragm was elevated, filling the abdominal and thoracic spaces. Depending on the elevation, all organs were moved to the left antimere. After dissecting the surrounding structures and analyzing the causes for the increase in volume, it was observed that the right lung formed a structure containing a large amount of purulent exudate, which was delimited by the right hemidiaphragm. It had a length of 111 cm, width of 40 cm, and wingspan of 137 cm, starting from the first thoracic rib to the last lumbar rib, near the peduncle region. After making an incision in the right hemidiaphragm and visceral pleura, approximately 70 L of purulent exudate and caseous material were removed. Since the right lung was severely damaged, visualizing the pulmonary parenchyma was not possible, and only remains of the main right bronchus could be seen.Discussion: Domestic species, such as dogs and cats, when affected by pleural empyema, usually have a restrictive breathing pattern (shallow and rapid breaths) and fever. Interpreting the clinical signs may be difficult for manatees because of their slow metabolism. In the United States, 44 (6%) cases of pleural empyema were recorded in manatees from a total of 731 animals evaluated, and shock with boats was determined as the primary cause. In the present animal, no signs of bone fractures were found, suggesting that the infection may have been caused by the use of an orogastric tube or even acquired in the environment prepared for acclimation. Based on the pathognomonic macroscopic findings, one can conclude that the animal had a characteristic clinical picture of pleural empyema (pyothorax) associated with an infection of unknown origin. This situation resulted in complete degeneration of the right lung and massive thoracic and abdominal distensions, resulting in decreased expansion capacity of the left lung, making breathing impossible, thus leading to death.

Background: Cholangiocarcinoma is an epithelial cell malignancy arising at various locations within the biliary tree. Primary liver tumors can be classified morphologically as solid, when a single large tumor involves only one liver lobe; nodular, when multiple tumors are located in different liver lobes; diffuse, when either multifocal nodular changes occur in different liver lobes or when diffuse changes occur throughout the liver. Surgery is the treatment of choice for these tumors because there is no established, effective chemotherapy protocol. This paper reports on the management of a dog with diffuse cholangiocarcinoma.Case: A 13-year-old female, castrated Pinscher, weighting 6 kg, was admitted at the Veterinary Medical Teaching Hospital of the Federal University of Rio Grande do Sul (UFRGS) with clinical signs of abdominal distension and dyspnea that had started one month ago. The patient had been subjected to total unilateral mastectomy to remove an adenocarcinoma. At clinical examination, the animal presented anemia, an area of silence during pulmonary auscultation on the right hemithorax,and hepatomegaly. Because of the chronicity and nonspecific signs, additional tests were requested. Abdominal ultrasound exam showed hepatomegaly with irregular echotexture; cavity areas scattered throughout the organ, especially by the right medial lob; discrete presence of free abdominal fluid. Thoracic radiography showed increased radiopacity in themedial and caudal right hemithorax, suggesting metastasis. Laboratory tests included a complete blood count (normocytic mycrocytic anemia), an albumin count (27.49 g/L), an alanine amino-transferase test (77.40 U/L), an alkaline phosphatase test (284.94 U/L), a creatinine test (0.81 mg/dL), a conjugated bilirubin test (0.1 mg/dL), a not conjugated bilirubin test (0.1mg/dL), and a total bilirubin test (0.2 mg/dL). After blood transfusion, a hepatic lobectomy was performed. An incision was made along the ventral midline. A tumoral mass, approximately 20 cm in diameter, was observed in the right medial lobe, as well as diffuse changes throughout all hepatic lobes. A total lobectomy was performed by applying the mass ligationtechnique by placement of a circumferential ligature around the liver hilus. The abdominal cavity was sutured routinely. Histopathological examination showed primary cholangiocarcinoma. The animal had excellent postoperative recovery after six days. Subsequently, the patient again succumbed to hepatomegaly, ascites, anemia, and lethargy, and the ownerchose to euthanize the patient and did not authorize a necropsy.Discussion: The cholangiocarcinoma was classified as primary and diffuse because of the macroscopic characteristics of the liver, since there were diffuse changes throughout the organ. Surgical excision was the treatment of choice. Although the prognosis was better in the early stages, lobectomy was chosen in order to improve the patient’s respiratory condition and, consequently, improve the quality of life. There were no surgical complications and the patient presented good postoperative recovery. After 60 days of the surgical procedure, clinical signs recurred (anemia, hyporexia and abdominal distension) and euthanasia was performed. Hepatic lobectomy in an animal with advanced stage cholangiocarcinomaprovided good quality of life for a period of 60 days.Keywords: neoplasm, liver, surgery, hepatectomy.

ABSTRACT: This study describes a case of parvovirus infection in a river otter (Lontra longicaudis) assisted at the Wildlife Rehabilitation Center and Wildlife Screening Center, Federal University of Pelotas (UFPel), Rio Grande do Sul state, Brazil. Clinical signs included apathy, dark and fetid diarrhea, and crusted lesions on the palmar pads of the fore and hind limbs. The animal died after undergoing support treatment with antibiotics, anti-inflammatory, and fluid therapy. At necropsy, the intestines were reddened and edematous and the right kidney was diminished by one third of its normal size and covered with whitish, spongy material. A female Dioctophyma renale was found free in the abdominal cavity. Histologically, dilatation of the intestinal crypts and fusion and blunting of the intestinal villi were observed. In addition, moderate, multifocal lymphocytic enteritis with lymphoid depletion in Peyer’s patches and mesenteric lymph nodes were present. Immunohistochemistry with anti-canine parvovirus monoclonal antibody (anti-CPV) was strongly positive in the bone marrow cells and enterocytes of the intestinal crypts, confirming the diagnosis of parvovirus infection. The peritoneum on the right kidney was expanded with a cuboidal cell border, forming multiple papillary projections associated with eggs of D. renale and severe inflammatory infiltrate (giant cells, macrophages, lymphocytes, eosinophils, and plasma cells). Areas of necrosis and mineralization were also observed. Due to fragmentation and degradation of its natural habitat, the otter approached the urban area and was contaminated with the virus, which is hosted and disseminated by domestic animals. Infection with D. renale can be associated with the large population of parasitized domestic animals, which eliminate the helminth eggs through urine, contaminating the environment where the parasite intermediate and paratenic hosts co-inhabit. The diseases of these animals can be a decline factor of wild populations that inhabit the region and are an alert to spillover risk.

Background: Dioctophimosis is a parasitic disease caused by Dioctophyma renale, more commonly known as "giant Kidney worm," and can be found in other organs or free in the abdominal cavity, which is related to the patient's eating habits. Most of the animals affected are asymptomatic. The diagnosis is made through ultrasonography, finding eggs of the parasite in the urine, or necropsy. The treatment of choice is nephrectomy of the affected kidney. We aimed to report the accidental diagnosis of parasitism by D. renale in an 8-year-old dog, which was surgically treated by nephrectomy of the right kidney after evident destruction of the renal parenchyma on ultrasonography.Case: An 8-year-old Boxer female dog underwent a physical examination and showed a mass in the region of the left caudal thoracic breast, bilateral alopecia on flanks, and purulent ocular secretions. Laboratory tests of complete blood count (CBC) and serum biochemical profile, X-ray examination, and ultrasonography were requested. Anemia was observed on the erythrogram, and enzymes (creatinine, urea, alanine aminotransferase [ALT], and albumin) were within normal limits. There were no abnormalities on X-ray examination, and abdominal ultrasonography showed slight splenomegaly, enlarged left kidney, reduced corticomedullary region, measuring approximately 7.63 cm longitudinally. In the right kidney, loss of the renal parenchyma, measuring approximately 5.49 cm in diameter and the presence of a cylindrical and rounded structure, typical of D. renale infection. After this, a urinalysis was suggested, which revealed the presence of the helminthic eggs, confirming the diagnosis. The owner was informed about the need for nephrectomy of the affected kidney as treatment. The kidney showed destruction of the renal parenchyma. A single parasite was removed, measuring approximately 46 cm in length. The patient was successfully treated and was hospitalized for 4 days for observation and evaluation of function of the contralateral kidney.Discussion: The parasitic infection of the animal was due to the ingestion of fish contaminated by the aquatic anelid Lumbriculus variegatus, and the reported patient had access to home-cooked food and ingested water near the farm. D. renale is the largest nematode capable of parasitizing the kidney, reaching up to 100 cm in length, and was 46 cm long in the present case. Usually, when there is unilateral involvement, the vast majority of parasitized animals do not present clinical signs or show nonspecific signs such as hematuria and apathy, or as observed in the present case, the patient is asymptomatic. The diagnosis often occurs through ultrasonography and urine tests, which are considered essential to diagnose the parasite, but the diagnosis is often made on necropsy. Due to its proximity to the duodenum, the parasite is usually found in the right kidney, and it may be found in other organs as well. In the present case, the parasite was found in the right kidney of the patient. Usually, hypertrophy of the contralateral kidney (7.86 cm in this case) is observed on ultrasonography, which is a compensatory mechanism for the lack of normal function of the affected kidney of the affected kidney. The case occurred in the state of Mato Grosso, where there are no records of parasitism by D. renale in domestic dogs, compared with other states. Since the parasite usually affects the kidney, the treatment of choice is nephrectomy, especially if the other kidney can compensate for the absence of the other kidney, a technique that proved to be effective with excellent prognosis in the patient described.

Introduction: Abdominal emergencies occur in pregnant women with the rate of 1:500−635 pregnancies. Such conditions usually develop from full health and worsen rapidly. Symptoms are often similar to those in physiological pregnancy (abdominal pain, vomiting, constipation). The diagnostic process is thus difficult and both the mother and her child are at risk. Our aim was to evaluate the frequency of abdominal emergencies in the Department of Surgery, University Hospital in Pilsen and to consider their impact on pregnancy and on the newborn. Methods: We acquired a set of patients by retrograde collection of data. We searched for pregnant patients suspected of developing an abdominal emergency admitted to the Department of Surgery, Faculty of Medicine, Pilsen between 2004 and 2015. We evaluated a number of clinical signs to statistically describe the set. Results: The set included 121 patients; 42 of the patients underwent a surgical procedure and 79 received conservative treatment. 38 patients underwent appendectomy; 6 appendixes were with no pathologies. McBurney’s incision was an approach of choice in most cases. The most frequent symptom was pain in the right lower abdominal quadrant. The foetus has been lost in none of the cases. Conclusion: Acute appendicitis was the most frequent abdominal emergency in our set and also the most frequent reason for surgical intervention. The most specific sign was pain in the right lower abdominal quadrant. No impact of appendicitis or appendectomy on the health of the newborn has been observed. Even though abdominal emergencies in pregnancy are relatively rare, the results of the department are very good.
