Linfadenectomia laparoscópica em cadela com neoplasia mamária

The laparoscopic lymphadenectomy is routinely performed in medicine, but not in veterinary medicine. This report describes a case of female canine with tumors in the left mammary chain (M4 and M5), which was subjected to intra-dermal application of sterile methylene blue, around the largest tumor (M5) which tried to demarcate the lymphatic vessels and regional lymph nodes. After 15 minutes, laparoscopic lymphadenectomy involving the abdominal in the left pelvic region started, followed by laparoscopic ovariohysterctomy (OVH) using three portals access. It was also performed an unilateral left total mastectomy. For histology, two abdominal lymph nodes were free of tumor cells. The patient had no recurrence in 60 days.

Dilatação esofágica endoscópica associada ao uso de triancinolona intramural em cadela com estenose de esôfago após ovariohisterectomia eletiva

The acquired esophageal stenosis usually occurs due to a severe esophagitis, resulting in the healing process with proliferation off ibrous tissue. Is gastroesophageal refluxin anesthetized animals among the reasons of this disease. This paper reports a case of esophageal luminal endoscopic dilations associated with intralesional triamcinolone in a bitch with esophageal strictures. A mongrel canines hows regurgitation and progressive weight loss. These signs appeared after elective laparoscopic OVH performed, where the patient had part of regurgitation during surgery. Based on clinical and endoscopic findings it was possible to diagnostic stenosis in the final third of the cervical esophagus. The treatment was done with esophageal dilations and intraluminnal triamcinolone administration. This procedure was repeated once a week for four weeks. The 15th dilatation occurred 14 days after the 14th. The patient was discharged after seven days of the final dilatation with no more regurgitation, even when feeding dry kibble within o incline. We concluded that the esophageal dilation associated with in tralesional triamcinolone were effective esophageal strictures treatment in this case.

Ovariohisterectomia videoassistida com dois portais para o tratamento de piometra em cadela

This report describes pyometras treatment in a bitch which was submitted to video-assisted ovariohysterectomy by two portals. The approach into abdominal cavity was carried through two midline incisions of 1cm each, and the ovaries fixed in the abdominal wall by a transcutaneous suspension suture and after the identification of the vascular bed, titanium clips were placed for hemostasis with subsequent section of the ovarian stumps. The pre-pubic incision had to be enlarged to remove the ovaries and uterine horns, ligating the uterine body externally by the conventional technique. The video-assisted treatment of pyometra with two portals was performed in able surgical time when compared with similar procedures described, without complications and minimal blood loss.

Laparoscopic-assisted prepubic urethrostomy in a cat with urethral stenosis

Urethrostomy is a surgical technique used in cases of partial or total obstruction of the urethra, and the laparoscopic approach may be a treatment option. Due to the scarcity of studies involving the technique, this paper reports the case of laparoscopic-assisted pre-pubic urethrostomy (hybrid laparoscopic) in a cat with urethral stricture. A five-years-old cat presenting recurrent feline lower urinary tract disease (FLUTD) had undergone to perineal urethrostomy two years and nine months ago. After this procedure, the patient underwent another four corrective surgeries without success. Laboratory tests (blood count and biochemical) and image diagnosis were realized. The patient was subjected to laparoscopic-assisted pre-pubic urethrostomy and it was achieved therapeutic success and adequate patient quality of life. It is concluded that this technique is feasible and safe in cats, making it a possible choice of surgical treatment for urethral stricture.

Doença vestibular em cães: 81 casos (2006-2013)

Eighty-one cases of vestibular disease in dogs were diagnosed by the neurology service in a veterinary teaching hospital in southern Brazil from 2006 to 2013. Approximately 2/3 of these cases were interpreted as central vestibular disease (CVD) with the remaining cases being considered as peripheral vestibular disease (PVD). Pure breed dogs, especially Dachshunds (PVD) and Boxers (CVD) were more affected than mixed breed dogs. The main clinical signs observed in cases of CVD and PVD included head tilt, vestibular ataxia, and ventral or ventrolateral strabismus. Proprioceptive deficits, cranial nerve V-XII dysfunction, and changes in the levels of conscience were observed only in cases of CVD, whereas absence of palpebral reflex occurred only in cases of PVD. Inflammatory or infectious diseases, especially canine distemper and bacterial otitis were the most commonly observed conditions associated with CVD and PVD, respectively. This article establishes the epidemiology (sex, age, and breed) and prevalence of clinical signs related to canine vestibular disease in the Central Rio Grande do Sul State; discusses the use of the clinical findings in the correct diagnosis and differentiation between CVD and PVD; and defines the main specific diseases responsible for the occurrence of CVD and PVD in dogs.

Biópsia hepática celioscópica em jundiás (Rhamdia quelen)

Endosurgery has been used for assessment of fish celomatic cavity, as well as for obtaining biopsies for organic analysis. Such minimally invasive access may also be used for the analysis of environmental impact on biomarkers of pollution. In Brazil, studies and literature regarding the use of celioscopy in fish are sparse. The purpose of the current study was to develop a two-port celioscopy technique to obtain liver biopsy in silver catfish (Rhamdia quelen). Six adult female silver catfish were used. The animals were anesthetized and the inspection of the celomatic cavity were performed using a telescope and celioscopic-guided liver biopsy were taken using laparoscopic Kelly forceps. On the early postoperative period, the animals were released in a confined water reservoir where mortality could be checked. The liver samples were sent for histological assessment. There were no complications during surgery on early postoperative period. It was possible to visualize meticulously several organs (liver, spleen, stomach, pancreas, swim bladder, ovaries, bowel and transverse septum). In conclusion, the surgical technique and the anesthetic protocol proposed were suitable to perform liver biopsies in silver catfish and provided low morbidity.

Laparoscopic repair of congenital pleuroperitoneal hernia using a polypropylene mesh in a dog

Pleuroperitoneal hernias are the most uncommon type of diaphragmatic hernias in dogs and cats. The treatment of choice is surgery and may involve the use of prosthetic implant through celiotomy. In the current report, laparoscopic repair of a congenital pleuroperitoneal hernia using polypropylene mesh in a dog is described. The surgery was feasible. Appropriate reduction of the hernia was carried out and no complications were noted.
