To determine the prevalence of splenic malignancy in cats undergoing splenectomy and to investigate possible factors associated with post-operative outcome.
62 client-owned cats that underwent splenectomy.
Medical records of 4 UK-based referral hospitals were searched and data reviewed retrospectively over 17 years. Factors associated with outcomes post-splenectomy were analyzed.
50 out of 62 cats (81%) were diagnosed with splenic neoplasia. Mast cell tumor ([MCT], 42%), hemangiosarcoma ([HSA], 40%), lymphoma and histiocytic sarcoma (6% each) were the most common tumor types. Fifteen cats (24%) presented with spontaneous hemoabdomen and were all diagnosed with splenic neoplasia. The diagnostic accuracy of cytology to detect splenic malignant lesions was 73% (100% for MCTs and 54% for mesenchymal tumors). Median survival time for cats with nonneoplastic splenic lesions was 715 days (IQR, 18 to 1,368) and 136 days for cats with splenic neoplasia (IQR, 35 to 348); median survival time was longer for cats with splenic MCT when compared to cats with HSA (348 vs 94 days; P < .001). Presence of metastatic disease and anemia (PCV < 24%) at diagnosis were associated with a poorer survival when considering all cats. Presence of anemia, a splenic mass on imaging or spontaneous hemoabdomen were associated with a diagnosis of HSA (P < .001).
Benign splenic lesions were uncommon in this cohort of cats. Spontaneous hemoabdomen should prompt the clinician to suspect neoplasia in cats with splenic disease. Anemia and evidence of metastasis at diagnosis were poor prognostic factors regardless of the final diagnosis.
To identify complications associated with and short- and long-term outcomes of surgical intervention for treatment of esophageal foreign bodies (EFBs) in dogs.
63 client-owned dogs.
Patient records from 9 veterinary hospitals were reviewed to identify dogs that underwent surgery for removal of an EFB or treatment or an associated esophageal perforation between 2007 and 2019. Long-term follow-up data were obtained via a client questionnaire.
54 of the 63 (85.7%) dogs underwent surgery after an unsuccessful minimally invasive procedure or subsequent evidence of esophageal perforation was identified. Esophageal perforation was present at the time of surgery in 42 (66.7%) dogs. Most dogs underwent a left intercostal thoracotomy (37/63 [58.7%]). Intraoperative complications occurred in 18 (28.6%) dogs, and 28 (50%) dogs had a postoperative complication. Postoperative complications were minor in 14 of the 28 (50%) dogs. Dehiscence of the esophagotomy occurred in 3 dogs. Forty-seven (74.6%) dogs survived to discharge. Presence of esophageal perforation preoperatively, undergoing a thoracotomy, and whether a gastrostomy tube was placed were significantly associated with not surviving to discharge. Follow-up information was available for 38 of 47 dogs (80.9%; mean follow-up time, 46.5 months). Infrequent vomiting or regurgitation was reported by 5 of 20 (25%) owners, with 1 dog receiving medication.
Results suggested that surgical management of EFBs can be associated with a high success rate. Surgery should be considered when an EFB cannot be removed safely with minimally invasive methods or esophageal perforation is present.
