Nephrectomy in 52 dogs for the treatment of Dioctophyme renale infection - Knowing the enemy to win.

Dioctophyme renale (D. renale) is a nematode that parasitizes the kidney of mammals. Treatment is often surgical, with removal of the affected organ. This retrospective study aims to evaluate the epidemiological, clinical, and surgical aspects, the interval between diagnosis and treatment, the occurrence of pre- and intraoperative complications, and the postoperative survival time of dogs parasitized by D. renale undergoing therapeutic nephrectomy. Records of fifty-two dogs treated in a single hospital service were analyzed. We collected epidemiological data, laboratory results, diagnostic method, anesthetic protocol, surgical technique and time, type of antimicrobial prophylaxis, pre- and intraoperative complications, location and number of parasites, and postoperative survival time. Of the 52 dogs undergoing right nephrectomy by laparotomy, 61.5 % were female and 63.4 % were adults. Although the most common clinical sign was hematuria (25 %), 61.5 % of the patients were asymptomatic. Eosinophilia and increased serum urea were the only laboratory changes found. The interval between diagnosis and surgery was 27.4 ± 23 days and no patient showed changes suggestive of surgical emergency. The most common surgical approach was the right paracostal (61.5 %), and a continuous suture pattern was predominant. Intraoperative complications occurred in 9.6 % of the procedures, varying from mild to severe hemorrhage. Mean postoperative survival was 835.5 ± 428 days. Dioctophymosis was effectively controlled by nephrectomy of the affected kidney, allowing a mean survival of more than 830 days. No serious complications caused by intervals between diagnosis and treatment have been reported. This is the largest retrospective study evaluating dogs infected with D. renale that were surgically treated.

Gasless laparoscopic renal biopsy in canine cadavers: a preclinical study.

In this study we aimed to analyze the feasibility of the gasless renal biopsy technique in canine cadavers. The cadavers were randomly divided into two groups: laparoscopic GCG, in which gasless laparoscopy was performed and GCP, laparoscopy with pneumoperitoneum was performed. The procedures were randomly performed on the right and left kidneys. The total surgical time, procedural steps, and intraoperative complications were recorded. The degree of difficulty of the surgical approaches was evaluated by the surgeon, assistant, and external evaluators. Renal samples were evaluated for quality, number of glomeruli, and proportion of renal cortex. The total operative time was higher in the GCG group than in the GCP group (p < 0.01). Additionally, positioning of the second portal and platform positioning took longer than the other steps. The surgical groups differed from each other in the Likert scale values for almost all the parameters regarding the difficulty of the surgical approaches (p < 0.05), with higher scores in the GCG group than in the GCP group. Based on the video recordings, the GCP group had higher scores than the GCG group for degrees of difficulty of the approach (p < 0.05). Renal histological parameters were similar between the surgical groups and surgical sides. Our study findings indicate that the proposed gasless renal biopsy technique is feasible. The longer operative time and technical difficulties in the gasless approach did not affect the quality of the renal specimens.

Neste estudo objetivamos analisar a viabilidade da técnica de biópsia renal gasless em cadáveres caninos. Os cadáveres foram divididos aleatoriamente em dois grupos: GCG laparoscópico, no qual foi realizada laparoscopia gasless e GCP, onde foi realizada laparoscopia com pneumoperitônio. Os procedimentos foram realizados aleatoriamente nos rins direito e esquerdo. O tempo cirúrgico total, etapas do procedimento e complicações intraoperatórias foram registrados. O grau de dificuldade das abordagens cirúrgicas foi avaliado pelo cirurgião, assistente e avaliadores externos. As amostras renais foram avaliadas quanto à qualidade, número de glomérulos e proporção do córtex renal. O tempo operatório total foi maior no grupo GCG do que no grupo GCP (p < 0,01). Além disso, o posicionamento do segundo portal e o posicionamento da plataforma demoraram mais do que as outras etapas. Os grupos cirúrgicos diferiram entre si nos valores da escala Likert para quase todos os parâmetros relativos à dificuldade das abordagens cirúrgicas (p < 0,05), com escores mais elevados no grupo GCG do que no grupo GCP. Com base nas gravações de vídeo, o grupo GCP obteve pontuações mais altas que o grupo GCG para graus de dificuldade da abordagem (p < 0,05). Os parâmetros histológicos renais foram semelhantes entre os grupos cirúrgicos e os lados cirúrgicos. Os resultados do nosso estudo indicam que a técnica proposta de biópsia renal gasless é viável. O maior tempo operatório e as dificuldades técnicas na abordagem sem gás não afetaram a qualidade das amostras renais.

A positive association of larval therapy and hyperbaric oxygen therapy in veterinary wound care.

The treatment of cutaneous wounds is part of the veterinary routine from initial scientific reports due to being regularly present condition. Currently, several types of treatments are available to accelerate the healing process. This report presents the case of a dog with multiple lesions in the thoracic limbs resulting from a car accident, who underwent larval therapy and hyperbaric oxygen therapy (HBOT). The animal was a 2-year-old female mixed breed dog presenting severe skin degloving, fracture in the left thoracic limb (LTL), with abrasion lesions and dislocation in the right thoracic limb (RTL). The animal underwent multiple modality therapies, such as HBOT sessions associated with larval therapy; even after the LTL presented gangrene, this treatment resulted in optimal viability of the non-necrotic tissue adjacent to the gangrene. Due to chronic pain unresponsive to drug control and the presence of a fracture at a location where a possible exoprosthesis was supposed to be fixed, the LTL ended up being amputated. There are several reports of the use of HBOT or larval therapy in traumatized limbs; however, the combination of both therapies has not been previously described in the veterinary literature. Thus, we demonstrate through this report that it was possible to quickly recover the animal with good wound resolution through tissue oxygenation and a healthy granulation bed, both provided by the therapeutic combination.

Coelioscopic-assisted prefemoral ovariosalpingectomy in a d`Orbigny slider (Trachemys dorbigni) using a digital otoscope.

The purpose of this study was to assess the unilateral prefemoral coelioscopic-assisted approach for ovariosalpingectomy in a d`Orbigny slider (Trachemys dorbigni) using a digital otoscope. Twenty healthy turtles were randomly assigned to one of two groups, for right (GR; n=10) or left (GL; n=10) prefemoral access, for coelioscopic-assisted ovariosalpingectomy. Anesthesia and surgery times, body weight, and ovary/oviduct weight data were recorded. Anesthesia and surgery times did not differ significantly between the groups. Wound closure was the most time-consuming surgical step. Ovary and body weights significantly affected the exposure time of the ipsilateral and contralateral ovaries, respectively. Two intraoperative complications were reported. All the animals recovered uneventfully. The digital otoscope can be safely and effectively used for coelioscopic-assisted single-access, unilateral prefemoral ovariosalpingectomy in d`Orbigny slider.

Two-portal video-assisted colopexy in the treatment of intussusception and prolapse of the descending colon in a lamb.

A lamb presented with recurrent prolapse of the descending colon. On clinical examination, intussusception of the descending colon with the prolapse of a segment was verified. The external anal sphincter had a rupture, extending to the lacerated wound in the anus. The lamb underwent colopexy with the two-portal video-assisted incisional technique and was discharged 6 days after the surgical procedure with a satisfactory clinical outcome. There were no recurrences or complications for at least 9 months. Video-assisted colopexy is an alternative treatment for intussusception and recurrent colon prolapse in sheep, even in the presence of an external anal sphincter rupture.

Urethral prolapse corrected by microsurgery in a cat: a case report.

Urethral prolapse is a rare condition in dogs and cats. A 7-month-old male cat presented with intermittent penile bleeding and a red mass protruding from the tip of the penis. Urethral prolapse was diagnosed by using a surgical microcamera to examine the genital area. Urethroplasty and preputial advancement surgery were performed using a surgical microscope, to successfully correct the urethral prolapse.
