The object of the present study was to compare abnormal serum canine pancreas-specific lipase results and pancreatic ultrasonographic findings in dogs with pancreatitis. Pancreatitis is a common disease in dogs that is difficult to diagnose. The noninvasive diagnostic procedures, including a serum canine pancreatic-specific lipase (cPL) test and ultrasonographic changes in the pancreas, can be considered for the diagnosis of canine pancreatitis in clinical practice. A retrospective study was performed to assess pancreatitis in dogs. Forty client-owned dogs were suspected to have pancreatitis, which was confirmed by abnormal serum SNAP cPL results. Abdominal ultrasound examinations were also performed. The present study investigated the distribution of clinical signs associated with pancreatitis, and the dogs were divided into two groups: group 1 (clinical signs compatible with pancreatitis; n = 30) and group 2 (no clinical signs; n = 10). Based on this study, an abnormal result on the SNAP cPL assay can still present as a normal pancreas through an ultrasonographic examination, and a normal health status can identify the status of pancreatic ultrasonographic abnormal lesions. Therefore, for dogs with suspected pancreatitis, it is important to repeat an ultrasonographic evaluation. There is no significant difference between clinical symptoms and ultrasonographic changes in the pancreas.

In acute pancreatitis group, all the dogs are showed increase of amylase and lipase after the 1st day of surgery, and amylase and lipase activity were significantly more increased than those of control group. The methemalbumin was increased significantly after the 2nd day of surgery in the acute pancreatitis group. In pancreatitis group, ultrasonographic findings included thickened duodenal wall and poorly circumscribed hyperechoic lesion of pancreatic mass after the 2nd day of surgery. And the lesion was exacerbated until the 4th day and reduced after the 6th day of surgery. To identify the lesion of pancreas, it is considered that transverse view is more useful Than sagittal view. Gross findings showed increase of pancreatic parenchymal consistency, surface nodule, and extensive pancreatic necrosis. Necrosis of peripancreatic fat tissue was also a prominent feature. The microscopic appearance of the pancreas was characterized by pancreatic acinar cell necrosis, hemorrhage, infiltration of the inflammatory cell and fat necrosis and saponification were also observed.

Background: Pancreatitis is a common disease in which 37% of dogs had evidence of acute or chronic pancreatitis at necropsy. Although biopsy is still the gold standard to diagnose acute pancreatitis, clinical data including ultrasonographic findings and measurement of canine serum pancreatic lipase immunoreactivity (cPLI) are used in routine. However, it may be insufficient in the diagnostic approach to acute pancreatitis. Objectives: To evaluate the clinical diagnostic feasibility of two-dimensional shear wave elastography (2D SWE) on canine acute pancreatitis for enhanced diagnostic confidence. Methods: 2D SWE was used to assess pancreatic stiffness and determine the correlation between pancreatic shear wave velocity (SWV) and Spec cPL concentration in 31 dogs with healthy pancreas and 10 dogs with acute pancreatitis. Results: The pancreatic SWV was significantly higher in the acute pancreatitis group (2.67 ± 0.20 m/s) than in the healthy pancreas group (2.30 ± 0.26 m/s; p < 0.05). The moderate positive correlation was found between the pancreatic SWV and Spec cPL concentration (95% confidence interval, 0.214-0.693; r = 0.489; p < 0.05). Conclusions: These results indicated that 2D SWE was feasible for assessing pancreatic stiffness in acute pancreatitis, and that pancreatic SWV using 2D SWE correlated with Spec cPL concentration. SWE could provide a quantitative measure of pancreatic stiffness, which can increase the accuracy of diagnosing acute pancreatitis in dogs. The 2D SWE can be used as a complementary imaging modality for diagnosing acute pancreatitis in dogs.

An eight-year-old, intact female, Shih-Tzu, weighing 4.5 kg presented with complaints of anorexia, pale mucous membrane, and vomiting for the past 5 days. On physical examination, nausea, abdominal pain, and melena were noted. On hematologic examination, severe anemia and thrombocytosis were identified. On radiographs examination, soft tissue opacity with small faint mineral opacity mass in the mid-abdomen and two mineral opacity regions in the cranial aspect of mass were identified. Ultrasonographic findings showed thickening of descending duodenal wall with loss of layering and mineralization within the duodenal wall and mesentery adjacent to the duodenal lesion. Computerized tomography showed circumferential wall thickening of descending duodenum with mineralization. Mineralization of the mesentery and mesenteric lymph nodes was identified. Based on the diagnostic imaging, the tentative diagnosis was descending duodenal tumor with dystrophic mineralization. Endoscopy revealed mucosal hemorrhage and erythema within the descending duodenum and stomach. Surgery was performed, and mineralization in the pancreatic tail to duodenum and mesentery was found. Resection of the duodenum, regional lymph node, and mineralized pancreatic region and the duodenal anastomosis were performed. The histologic examination revealed a high-grade undifferentiated duodenal carcinoma with metastases to the regional lymph node and mesentery. The patient was managed with supportive therapy for 8 days and discharged. The patient was followed up for 5 months and there were no complications.
