Surgical fenestration combined with omentalization for the treatment of renal cysts in 2 dogs.

Two cases of surgical fenestration combined with omentalization for canine renal cysts using laparotomy and laparoscopy are described. After surgery, the cystic lesions gradually diminished in size, and a complete regression was confirmed in Case 2 by ultrasonography. The dogs maintained good condition without clinical signs of renal compromise for 14 months (Case 1) and 24 months (Case 2). Omentalization is a simple and effective procedure for canine renal cysts that conserves the remaining parenchyma and can be performed by a laparoscopic approach.

Fenestration chirurgicale combinée à une omentalisation pour le traitement de kystes rénaux chez deux chiens. Deux cas de fenestration chirurgicale combinée à une omentalisation pour traiter des kystes rénaux canins utilisant la laparotomie et la laparoscopie sont décrits. Après la chirurgie, les lésions kystiques ont graduellement diminué en grosseur, et une régression complète fut confirmée par échographie dans le Cas 2. Les chiens ont maintenu une bonne condition sans signe clinique de complication rénale pendant 14 mois (Cas 1) et 24 mois (Cas 2). L'omentalisation est une procédure simple et efficace pour les kystes rénaux canins qui conserve le parenchyme restant et peut être réalisée par une approche laparoscopique.(Traduit par Dr Serge Messier).

Presurgical assessment of splenic tumors in dogs: a retrospective study of 57 cases (2012-2017).

The purpose of this study was to evaluate the clinical and imaging characteristics of canine splenic tumors and to establish guidelines for the presurgical assessment of splenic tumors in dogs. Fifty-seven dogs that underwent total splenectomy for the treatment of splenic tumors were evaluated by examining medical records, hematologic results, diagnostic imaging results, and histopathologic results. The maximum lesion size from ultrasonography was significantly different between malignant and benign tumors (p = 0.002). There was a correlation between tumor margination and type of splenic tumors (p = 0.045). Precontrast lesion attenuation on computed tomography was significantly different between splenic malignant and benign tumors (p = 0.001). The mean ± SD precontrast lesion attenuation of malignant tumors was 40.3 ± 5.9 Hounsfield units (HU), and for benign tumors, it was 52.8 ± 6.8 HU. In conclusion, some variables of the imaging examination could be used to distinguish the type of splenic tumor. Based on the study results, using a diagnostic flowchart would be effective in increasing the survival rate of patients with splenic malignant tumors. In addition, fine needle aspiration or magnetic resonance imaging prior to surgical exploration and histopathologic examination may be useful in achieving a more accurate diagnosis.
