Abstract
The clinical presentations of both liver disease and pancreatitis are nonspecific and overlapping, which may cause difficulty in diagnosis. In our retrospective pilot study, we assessed whether dogs with evidence of portal hypertension and absence of pancreatitis on pancreatic histology have increases in canine pancreatic lipase immunoreactivity (cPLI) and 1,2-o-dilauryl-rac-glycero-3-glutaric acid-(6'-methylresorufin) ester (DGGR) lipase. We included dogs that had been presented between 2008 and 2019 if they had normal pancreatic histology, histologically confirmed hepatopathy, and if canine pancreas-specific lipase (Spec cPL; Idexx) or DGGR lipase had been measured. Only dogs with portal hypertension were included. Six dogs fulfilled the inclusion criteria. Four of 6 and 2 of 6 dogs had Spec cPL and DGGR lipase exceeding the upper reference limit, respectively. From the 4 dogs with increased Spec cPL, 2 had concentrations of 200-400 µg/L and 2 had concentrations ≥ 400 µg/L. Our results suggest that canine portal hypertension might lead to increased Spec cPL and DGGR lipase values in the absence of pancreatitis on histology. Until more evidence in a larger number of dogs with portal hypertension is available, both tests should be interpreted cautiously in the presence of portal hypertension.

Abstract
OBJECTIVE To evaluate dogs with computed tomography angiography of the abdomen for overall prevalence of portal vein thrombosis and prevalence of portal vein thrombosis based on different disease categories. To evaluate dogs with and without portal vein thrombosis for differences in outcome. To compare ultrasound to computed tomographic angiography for identification of portal vein thrombosis. METHODS Abdominal computed tomography angiography of 223 client-owned animals was reviewed for evidence of portal vein thrombosis. Based on medical records, dogs were assigned to disease categories: (1) liver disease; (2) non-hepatic neoplasia; (3) pancreatitis; (4) infectious disease; (5) immune-mediated disease; (6) other; (7) multiple diseases. Different categories were compared for the prevalence of portal vein thrombosis. Outcome was evaluated in dogs with and without portal vein thrombosis. Ultrasound reports were reviewed to determine the detection of thrombosis on ultrasound. RESULTS Twenty-eight dogs (13%) had portal vein thrombosis. The pancreatitis category contained the highest percentage of portal vein thrombosis among different categories (eight of 19; 42%). There was a similar outcome between dogs with and without portal vein thrombosis. Of 21 dogs with portal vein thrombosis that had ultrasound performed, ultrasound detected thrombosis in four of 21 (19%) cases. CLINICAL RELEVANCE In this study, portal vein thrombosis prevalence was higher in dogs with pancreatitis compared to dogs with liver disease, non-hepatic neoplasia and other abdominal or systemic disease. The portal system should be carefully evaluated with imaging in dogs with pancreatitis. As compared to ultrasound, CT angiography is the imaging method of choice for detection of portal vein thrombosis in dogs.

Abstract
CASE DESCRIPTION A 15-year-old 0.412-kg (0.906-lb) sexually intact male eclectus parrot (Eclectus roratus) was evaluated because its owners found it lethargic and dyspneic at the bottom of its cage. CLINICAL FINDINGS The parrot was thin and had generalized muscle wasting, diffuse feather loss, pale mucous membranes, and melena. The coelomic cavity was distended and soft on palpation, with coelomic effusion suspected. Results of a CBC indicated leukocytosis with left shift heterophilia, including toxic heterophils, lymphopenia, and anemia. Plasma biochemical analyses revealed severe hyperamylasemia. TREATMENT AND OUTCOME Radiography revealed no evidence of a metallic foreign body but severe loss of coelomic detail, suggestive of a coelomic mass, coelomic effusion with coelomitis, or both. Ultrasonography and CT revealed severe accumulation of coelomic fluid; a large, heterogeneous, irregularly marginated, and moderately vascularized mass in the caudal aspect of the coelomic cavity; and multiple hepatic, coelomic, and pulmonary nodules. On the basis of a poor prognosis, the parrot was euthanized. Necropsy results confirmed exocrine pancreatic adenocarcinoma, with disseminated metastases in the liver, gastrointestinal tract, coelomic cavity, and lungs. CLINICAL RELEVANCE In birds, pancreatic adenocarcinoma is rarely reported but should be considered a differential diagnosis for hyperamylasemia, coelomic mass, coelomic effusion, or abnormal gastrointestinal signs, alone or in combination. Ultrasonography and CT can be useful in further evaluating such patients and should be considered in the diagnostic plan.

Abstract
Background Pancreatitis in cats, although commonly diagnosed, still presents many diagnostic and management challenges. Objective To summarize the current literature as it relates to etiology, pathogenesis, diagnosis, and management of pancreatitis in cats and to arrive at clinically relevant suggestions for veterinary clinicians that are based on evidence, and where such evidence is lacking, based on consensus of experts in the field. Animals None. Methods A panel of 8 experts in the field (5 internists, 1 radiologist, 1 clinical pathologist, and 1 anatomic pathologist), with support from a librarian, was formed to assess and summarize evidence in the peer reviewed literature and complement it with consensus clinical recommendations. Results There was little literature on the etiology and pathogenesis of spontaneous pancreatitis in cats, but there was much in the literature about the disease in humans, along with some experimental evidence in cats and nonfeline species. Most evidence was in the area of diagnosis of pancreatitis in cats, which was summarized carefully. In contrast, there was little evidence on the management of pancreatitis in cats. Conclusions and Clinical Importance Pancreatitis is amenable to antemortem diagnosis by integrating all clinical and diagnostic information available, and recognizing that acute pancreatitis is far easier to diagnose than chronic pancreatitis. Although both forms of pancreatitis can be managed successfully in many cats, management measures are far less clearly defined for chronic pancreatitis.

Abstract
Case summary A 7-year-old neutered female domestic longhair cat was presented for further investigation of suspected hepatobiliary disease. Increases in serum 1,2-o-dilauryl-rac-glycero-3-glutaric acid-(6'-methylresorufin) ester lipase and hepatobiliary enzymes, with concurrent hypoalbuminaemia, were documented on blood biochemistry. Abdominal ultrasonography findings were consistent with acute pancreatitis with multiple pancreatoliths visualised within the pancreatic duct. Treatment for suspected triaditis was initiated with a hydrolysed protein diet, amoxicillin-clavulanate, hepatoprotectants and buprenorphine. Fifty-three days later, the patient presented with hypercalcaemia and obstructive pancreatolithiasis, and was euthanased. Post-mortem examination revealed severe chronic active pancreatitis with moderate chronic lymphocytic, plasmacytic cholangiohepatitis and mild chronic lymphocytic-plasmacytic duodenal enteritis (triaditis). Multiple calcium carbonate pancreatoliths present within the pancreatic ducts had resulted in pancreatic duct obstruction. Relevance and novel information Pancreatolithiasis is a very rare condition in cats, with only five reports to date. In human medicine, pancreatolithiasis is often a sequala to chronic pancreatitis, seen in up to 50-90% of patients. However, in cats the aetiology of pancreatolithiasis, and indeed chronic pancreatitis, is poorly understood. This report describes a case of obstructive pancreatolithiasis in a cat with histopathological confirmation of triaditis and is the first report of hypercalcaemia in a cat with obstructive pancreatolithiasis. This further adds to the evidence base that pancreatolithiasis may have a similar pathogenesis to humans and can develop secondarily to chronic pancreatitis in cats.

Abstract
Abdominal ultrasound examinations (AUEs) are commonly used in the diagnostic evaluation of canine acute pancreatitis (AP). The purpose of this retrospective study was to evaluate and monitor the ultrasonographic changes observed in dogs with clinically suspected AP on consecutive AUEs. The study population was constituted by 38 client-owned dogs hospitalized for no less than 48 h from January 2016 to December 2019. Dogs included in this study were suspected of AP based on the clinical examination and abnormal rapid specific canine pancreatic lipase test performed at admission. Dogs were submitted to two AUEs, the first on the first day of hospitalization, and the second between 40–52 h after the first one. Twelve dogs had both AUEs suggestive of AP. Fourteen dogs received an ultrasonographic diagnosis of AP exclusively on the second AUE. Twelve dogs remained negative on both the first and the second AUE. In 26 out of 38 patients the second AUE was suggestive of AP. If a patient is suspected of AP, it is advisable to carry out ultrasonographic monitoring at least within the first 52 h after admission, since ultrasonographic signs of AP may only become observable later after hospitalization.

Abstract
BACKGROUND Activity of 1,2-O-dilauryl-rac-glycero glutaric acid-(6'-methylresorufin) ester (DGGR) lipase in serum shows good agreement with pancreatic lipase (cPL) in dogs. Although prednisolone therapy does not seem to affect serum cPL concentration, its influence on DGGR lipase is unclear. OBJECTIVES The aim of the study was to evaluate the effect of prednisolone therapy on DGGR lipase serum activity in dogs. ANIMALS Thirty-four dogs were used, of which 17 dogs received prednisolone (study group) and 17 healthy dogs did not receive treatment. METHODS A prospective cohort study measured DGGR lipase activity in both groups at 3 time points: T0, T1, and T2, corresponding to days 0, 7-10, and 21-30, respectively. Dogs from study group presented a medical reason that justified the use of prednisolone for at least 3 weeks. Initial prednisolone dose was .5-2.0 mg/kg/day PO with a reduction at T1 to a final dose that was maintained until T2. DGGR lipase activity >160 U/L was defined as clinically relevant. RESULTS In the study group, DGGR lipase activity increased significantly from T0 to T1 (P = .02) and decreased significantly from T1 to T2 (P = .02). Median DGGR activity at each time point (T0, T1, and T2) was 24.74 (14.45-31.48), 36.82 (23.8-80.16), and 29.52 (15.91-48.48) U/L, respectively. In the control group, no significant changes were observed over time (P = .93). The DGGR lipase activity and prednisolone doses were not correlated for both T0-T1 (rs = .371, P = .14) and T1-T2 (rs = 0.390, P = .12). CONCLUSION AND CLINICAL IMPORTANCE DGGR lipase activity was affected by prednisolone administered orally in dogs. However, this variation was not clinically important as values remained below the relevant upper limit.

Abstract
BACKGROUND The measurement of pancreatic lipase is important for the diagnosis of feline and canine pancreatitis. Recent studies have claimed that lipase assays using the 1,2-o-dilauryl-rac-glycero-3-glutaric acid-(6'-methylresorufin) ester (DGGR) as a substrate are more specific for measuring pancreatic lipase than traditional lipase assays. However, the analytical specificity of this assay for pancreatic lipase has not been demonstrated. OBJECTIVES We aimed to determine whether hepatic and/or lipoprotein lipases can interfere with the DGGR-based assay results in cats and dogs. We, therefore, compared plasma lipase activities measured using DGGR-based and pancreatic lipase immunoreactivity (PLI) assays before and after administering heparin, known to cause the release of hepatic and lipoprotein lipases, in cats and dogs. METHODS Heparin was administered in six cats and six dogs. Blood was collected at baseline and 10, 20, 30, 60, and 120 minutes after heparin administration. Lipase activity was measured using a DGGR-based assay, and PLI concentrations were measured using the Spec fPL and cPL assays for cats and dogs, respectively. RESULTS Plasma lipase activities, as measured using the DGGR-based assay, increased significantly 10 minutes after heparin administration in both cats (P = .003) and dogs (P = .006) and returned to baseline by 120 minutes. In contrast, PLI concentrations showed no significant changes after heparin administration. CONCLUSIONS DGGR is not only hydrolyzed by pancreatic lipase but also by hepatic lipase, lipoprotein lipase, or both, in cats and dogs. Since these extrapancreatic lipases are also naturally present in cats and dogs, they could contribute to the lack of analytical specificity for the DGGR-based assays.

Abstract
Background Hyperlipasemia is frequent in critically ill people without evidence of acute pancreatitis (AP), and has been associated with increased morbidity and mortality. Objective To evaluate the prevalence of hyperlipasemia at admission and development of hyperlipasemia during hospitalization in critically ill dogs, explore factors associated with hyperlipasemia, and evaluate association with outcome. Animals Critically ill, client owned dogs (n = 1360), presented on emergency and admitted to the intensive care unit, that had 1,2‐o‐dilauryl‐rac‐glycero‐3‐glutaric acid‐(6′‐methylresorufin) ester (DGGR) lipase activity measured within 24 hours of admission. Methods Retrospective cross‐sectional study of clinical and laboratory records. Results The DGGR lipase activity was increased >3× the upper reference limit at admission in 216/1360 (16%) dogs, of which 70/216 (32%) had a clinical diagnosis of AP. Other primary conditions associated with hyperlipasemia were renal, endocrine, and immune‐mediated diseases, and upper airway obstruction. Predictors of hyperlipasemia at admission were prior glucocorticoid administration, vomiting and abdominal pain, increased age, plasma bilirubin and creatinine concentrations, and decreased hematocrit. Of dogs with repeat measurements, 78/345 (23%) had significantly increased lipase during hospitalization, of which 13/78 (17%) had a clinical diagnosis of AP. Other primary conditions associated with in‐hospital hyperlipasemia were renal and immune‐mediated disorders. Predictors of developing hyperlipasemia during hospitalization were hemodialysis events, increased plasma bilirubin and creatinine concentrations, and decreased hematocrit. Hyperlipasemia both at admission and during hospitalization was associated with longer hospitalization and higher mortality. Conclusions and Clinical Importance Significant DGGR‐hyperlipasemia is frequent in critically ill dogs and associated with a variety of nonpancreatic conditions and negative outcome.

Abstract
Background Pancreatitis is a common cause of extrahepatic bile duct obstruction (EHBDO) in dogs. Information describing the clinical course of dogs with pancreatitis associated bile duct obstruction (PABDO) is limited. Objectives To describe the clinical course of PABDO in dogs and determine if presumed markers of disease severity are predictors of survival. Animals Forty‐six client‐owned dogs with PABDO. Methods A retrospective review of medical records from dogs diagnosed with PABDO was performed. Data, including clinical signs and biochemical changes, were collected 6 times throughout the course of disease. Outcome was defined as either survival (discharge from the hospital) or death. Results Thirty‐three (79%) out of 42 dogs with PABDO survived. Thirty‐one (94%) of the 33 dogs that survived received medical management alone. Time from onset of clinical signs to initial documented increase in serum bilirubin concentration, peak bilirubin elevation, and initial decline in serum bilirubin concentration were 7 (median), 8, and 15 days, respectively. The median number of days from onset of clinical signs to outcome date was 13. Clinical signs of fever, vomiting, and anorexia were decreased in frequency from the onset of clinical signs to the time of peak bilirubin. Median bile duct dilatation at the time of ultrasonographic diagnosis of PABDO and peak bilirubin were not different between survivors (7.6 mm, 11.7 mg/dL) and nonsurvivors (6 mm, 10.6 mg/dL, P = .12, P = .8). Conclusions Dogs with PABDO often have a prolonged course of illness and improve clinically despite biochemical evidence of progression of EHBDO.

Abstract
Aims: To evaluate the association between the C-reactive protein (CRP)/albumin (ALB) ratio and survival in dogs with acute pancreatitis and its use as a prognostic marker for survival. Methods: Medical records of a veterinary referral hospital in Italy were retrospectively searched for dogs that were admitted with acute pancreatitis between January 2015 and April 2019, in which the concentrations of CRP and ALB in serum were measured at admission. The CRP/ALB ratio was calculated and the time between admission and discharge or death was recorded. Mortality rates overall and for dogs that died within 2 days of admission were calculated. A univariable Cox proportional hazard model was used to assess the relationship between survival time and CRP/ALB ratio. Results: Seventy-one dogs were included in the study. Of these, 19 died within 2 days of presentation; an early mortality rate of 26.8%, while 27 died before discharge for an overall mortality rated of 38%. Dogs with higher CRP/ALB ratio had a significantly greater mortality rate than dogs with lower CRP/ALB ratio: for every 1-unit increase in CRP/ALB ratio, the hazard of death over the study period increased by 130% (hazard ratio = 2.34; 95% CI = 1.53-3.58; p < 0.001). The optimal CRP/ALB ratio cut-off point for predicting mortality was 0.56, with a sensitivity and specificity of 88.9% and 68.2%, respectively (AUC = 0.82; p < 0.001). Conclusions: As in humans, the CRP/ALB ratio, may be a promising, though not particularly specific, prognostic marker for increased risk of death in dogs with acute pancreatitis.

Abstract
OBJECTIVE To evaluate the feasibility of contrast-enhanced CT for assessment of pancreatic perfusion in healthy dogs. ANIMALS 6 healthy purpose-bred female Treeing Walker Coonhounds. PROCEDURES Contrast-enhanced CT of the cranial part of the abdomen was performed with 3-mm slice thickness. Postprocessing computer software designed for evaluation of human patients was used to calculate perfusion data for the pancreas and liver by use of 3-mm and reformatted 6-mm slices. Differences in perfusion variables between the pancreas and liver and differences in liver-specific data of interest were evaluated with the Friedman test. RESULTS Multiple pancreatic perfusion variables were determined, including perfusion, peak enhancement index, time to peak enhancement, and blood volume. The same variables as well as arterial, portal, and total perfusion and hepatic perfusion index were determined for the liver. Values for 6-mm slices appeared similar to those for 3-mm slices. The liver had significantly greater median perfusion and peak enhancement index, compared with the pancreas. CONCLUSIONS AND CLINICAL RELEVANCE Measurement of pancreatic perfusion with contrast-enhanced CT was feasible in this group of dogs. Hepatic arterial and pancreatic perfusion values were similar to previously published findings for dogs, but hepatic portal and hepatic total perfusion measurements were not. These discrepancies might have been attributable to physiologic differences between dogs and people and related limitations of the CT software intended for evaluation of human patients. Further research is warranted to assess reliability of perfusion variables and applicability of the method for assessment of canine patients with pancreatic abnormalities.

Abstract
Background In humans, respiratory complications in patients with acute pancreatitis (AP) are a common life-threatening comorbidity. Since possible lung impairment has not been individually evaluated in canine AP, the aims of the present study were to: (1) describe the prevalence, types and severity of pulmonary complications in dogs with acute presentation of AP, and (2) evaluate their association with mortality. AP diagnosis was based on compatible clinical and laboratory parameters, abnormal canine pancreatic-lipase test, and positive abdominal ultrasound within 48 h from admission. The canine acute pancreatitis severity score (CAPS) was calculated for each dog at admission. Arterial blood gas analysis and thoracic radiography were performed at admission. Thoracic radiography was classified on the basis of pulmonary pattern (normal, interstitial or alveolar) and a modified lung injury score (mLIS) was applied to the ventrodorsal projections for each dog. VetALI/VetARDS were diagnosed using current veterinary consensus. Dogs were divided into non-survivors or survivors (hospital discharge). Clinical, radiological and blood gas parameters collected at presentation were compared between survivors and non-survivors and associated with mortality. Results This prospective cohort study included twenty-six client-owned dogs with AP. Twelve out of twenty-six dogs (46%) died or were euthanized. At admission, thirteen dogs showed respiratory distress at physical examination, which was associated with death (P < 0.001). Radiographic abnormalities were found in twenty-one dogs: alveolar (n = 11) and interstitial pattern (n = 10). Radiographic alterations and mLIS score were both associated with death (P = 0.02 and P = 0.0023). The results of the arterial blood-gas evaluation showed that non-survivors had lower PaCO2 and HCO3− levels, and higher A-a gradient than survivors (P = 0.0014, P = 0.019 and P = 0.004, respectively). Specifically, three dogs had aspiration pneumonia, and VetALI was diagnosed in nine dogs (34.6%), and no dogs met the criteria for VetARDS. The presence of VetALI was associated with mortality (P < 0.001). Conclusions As with humans, possible lung impairments, such as VetALI, should be investigated in dogs with acute presentation of pancreatitis.

Abstract
Background Serum feline pancreatic lipase immunoreactivity (fPL) commonly is used in the assessment of sick cats suspected to have pancreatitis but its diagnostic utility is debated. Objectives To evaluate the diagnostic utility of the Spec fPL test and selected serum biochemistry tests in the diagnosis of pancreatitis in cats. Animals Two hundred seventy‐four client‐owned cats presented to a university teaching hospital in the United Kingdom, from April 2013 to May 2017, in which Spec fPL was measured. Methods Cats were classified into 1 of 4 groups based on clinical signs (all cats), ultrasonographic findings (all cats) and histopathological or cytological assessment of the pancreas where available (9 cats) regardless of Spec fPL concentration. The groups were (a) definite pancreatitis (n = 9), (b) probable pancreatitis (n = 49), (c) possible pancreatitis (n = 139), and (d) unlikely pancreatitis (n = 77). Spec fPL and selected serum biochemistry test results were compared among groups. Results Serum fPL concentrations >5.3 μg/L were classified as positive and concentrations <3.5 μg/L were classified as negative. There was a significantly (P = .03) lower proportion of false‐positive results (cats unlikely to have pancreatitis, n = 77, with a positive fPL, n = 8, 10%) than false‐negative results (cats with definite or probable pancreatitis, n = 58, with a negative fPL result, n = 14, 24%). None of the selected biochemical tests were helpful diagnostically. Conclusion and Clinical Importance A positive Spec fPL result indicates that pancreatitis is a probable diagnosis, but the test cannot be used to rule the diagnosis out.

Abstract
BACKGROUND Diagnosis of pancreatic diseases in dogs is still challenging because of variable clinical signs, which do not always correspond with clinical pathology and histopathological findings. OBJECTIVES To characterize inflammatory and neoplastic pancreatic diseases of dogs and to correlate these findings with clinical findings and canine pancreatic lipase immunoreactivity (cPLI) results. ANIMALS Tissue specimens and corresponding blood samples from 72 dogs submitted for routine diagnostic testing. METHODS Four groups were defined histologically: (1) normal pancreas (n = 40), (2) mild pancreatitis (n = 8), (3) moderate or severe pancreatitis (acute, n = 11; chronic, n = 1), and (4) pancreatic neoplasms (n = 12). An in-house cPLI ELISA (<180 μg/L, normal; >310 μg/L, pancreatitis) was performed. RESULTS In dogs with normal pancreas, 92.5% of serum cPLI results were within the reference range and significantly lower than in dogs with mild acute pancreatitis, moderate or severe acute pancreatitis and pancreatic tumors. In dogs with moderate or severe acute pancreatitis, cPLI sensitivity was 90.9% (95% confidence interval [CI], 58.7%-99.8%). Most dogs (9/12) with pancreatic tumors (group 4) had additional pancreatic inflammation and cPLI results were increased in 10 dogs. CONCLUSIONS AND CLINICAL IMPORTANCE High cPLI indicates serious acute pancreatitis but underlying pancreatic neoplasms should also be taken into consideration. This study confirms the relevance of histopathology in the diagnostic evaluation of pancreatic diseases.

Abstract
Pancreatitis is a common clinical condition seen in companion animals. The correlation of the region of the pancreas affected to the presentation of clinical signs has not been previously described. A retrospective study on the clinical findings in 293 client-owned dogs diagnosed with suspect pancreatitis based on history, clinical signs, laboratory testing and abdominal ultrasonography was performed. Based on ultrasonography, dogs were divided into three groups: group 1: 41 dogs with ultrasonographic changes consistent with pancreatitis within the left lobe of the pancreas; group 2: 105 dogs with ultrasonographic changes compatible with pancreatitis within the right lobe of the pancreas; and group 3: 147 dogs with ultrasonographic evidence of diffuse pancreatitis. No significant differences regarding age, breed and sex were evident. Furthermore, statistical significance was demonstrated with the presence of pain in group 3; poor appetite in groups 2 and 3; and vomiting and diarrhoea in group 3. Pain is expected to occur with a higher frequency in diffuse pancreatitis, but it is not a common clinical sign. This may represent a more severe form of the disease when the pancreas is diffusely affected. Vomiting was more common than diarrhoea with both clinical signs more prevalent in dogs with diffuse pancreatitis, and this could be ascribed to gastric and intestinal tract involvement. Poor appetite occurred more frequently in dogs with diffuse and right lobe pancreatitis. A possible explanation can be attributed to the fact that the duodenum has many receptors and is referred to as the 'organ of nausea'.

Abstract
PRACTICAL RELEVANCE Abdominal ultrasound plays a vital role in the diagnostic work-up of many cats presenting to general and specialist practitioners. Ultrasound examination of the pancreas is a vital part of the investigation into feline pancreatic disease. CLINICAL CHALLENGES Despite ultrasonography being a commonly used modality, many practitioners are not comfortable performing an ultrasound examination or interpreting the resulting images. Even for the experienced ultrasonographer, differentiating between incidental findings such as nodular hyperplasia and pathological changes such as neoplasia can be challenging. AIM This review, part of an occasional series on feline abdominal ultrasonography, discusses the ultrasonographic examination and appearance of the normal and diseased pancreas. Aimed at general practitioners who wish to improve their knowledge of and confidence in feline abdominal ultrasound, this review is accompanied by high-resolution images and videos available online as supplementary material. EQUIPMENT Ultrasound facilities are readily available to most practitioners, although use of ultrasonography as a diagnostic tool is highly dependent on operator experience. EVIDENCE BASE Information provided in this article is drawn from the published literature and the author's own clinical experience.

Feline pancreatic ducts are consistently identified on CT and more likely to be dilated in the body of pancreas in cats with elevated feline pancreatic lipase immunoreactivity.

Abstract
Feline pancreatitis is a challenge to diagnose and no previously published study has described the CT characteristics of the pancreatic duct (PD) in cats. The current prospective analytical study was performed to identify and describe the CT characteristics of the PD in normal cats and to compare that to those cats with an elevated feline pancreatic lipase immunoreactivity (fPLI). Contrast-enhanced CT was performed in 16 normal cats and 13 cats with an elevated fPLI. Two ACVR-certified radiologists blinded to the fPLI status assessed whether or not the PD could be identified, contrast phase during which the PD was most conspicuous, and PD shape in the body, right and left lobes. A second-year radiology resident blinded to the fPLI status measured maximum PD diameter and PD:parenchyma. The PD was identified in 84 of 87 pancreatic segments, which was most conspicuous in the portal phase in 28 of 29 cats. The PD shape was tubular (48/84), tapered (34/84), or beaded (2/84) with no significant difference (P = 1.0 to .1615) between groups. Mean maximal PD diameters of normal cats were 1.5-1.7 mm, which was significantly larger in the body of the pancreas in cats with an elevated fPLI (2.4 mm, P = .0313). Mean PD:parenchyma was not significantly different between groups (P = .2001 to .949). In conclusion, the feline PD can be consistently identified on CT, for which the portal phase is preferred. Cats with an elevated fPLI are more likely to exhibit dilation of the PD in the body of the pancreas on CT.

Abstract
A 12-year-old neutered female mixed-breed dog was referred for occasional vomiting that had increased progressively in frequency over the past 3 months. Palpation of the abdomen revealed a firm mass of unknown aetiology, located within the cranial to mid abdomen, while abdominal surgical exploration revealed a well-defined abdominal mass of pancreatic origin. The pancreatic mass caused lateral displacement of the duodenum as well as medial displacement of the pylorus, resulting in impairment of pyloric outflow. Further examination revealed a firm, poorly vascularized and coarsely lobulated structure. The histopathological findings were consistent with severe pancreatic lipomatosis and atrophy. Immunohistochemically, the remnant pancreatic cells were positive for cytokeratins AE1/AE3 and glucagon, and negative for insulin. Routine follow-up with the referring veterinarian showed no evidence of postoperative complications, but the dog continued to deteriorate further and died despite medical management. Pancreatic lipomatosis is a rare condition in small animal practice. The aetiology or predisposing factors have not been identified in animals.

Abstract
BACKGROUND Acute pancreatitis (AP) is common in dogs. Nevertheless, validated clinical severity index (CSI) scoring systems to assess severity and guide treatment in current, large-scale studies are unavailable. METHODS This is a retrospective study including 109 dogs. Pancreatitis was diagnosed based on clinical signs, abdominal sonographic evidence, positive pancreatic lipase assays and experts' assessment consensus. RESULTS The survival rate was 75 per cent (82 dogs). Azotaemia and presence of local complications (ie, ascites) and secondary complications (ie, acute kidney injury and acute respiratory distress syndrome) were significantly associated with death. In agreement with the previously published CSI, respiratory anomalies were significantly associated with death. However, in disagreement with that study, high scores in the kidney and local abdominal complication categories and the sum of scores of all nine categories, but not high gastrointestinal category score, were also significantly associated with death. A final CSI score of at least 4 was associated with death. CONCLUSIONS This study has validated a nine-category CSI, proven a useful assessment tool in dogs with AP. Several previously reported and novel prognostic markers were assessed.

Abstract
Background Gastric wall edema has not been reported as a complication of acute pancreatitis in dogs. Objective To describe the ultrasonographic features of gastric wall thickening in dogs with acute pancreatitis. Animals Fourteen dogs with ultrasonographic evidence and clinical diagnosis of acute pancreatitis, with ultrasonographic evidence of increased gastric wall thickness (>5 mm). Methods A retrospective search in the medical records from 2014 to 2016 was performed to identify dogs that had ultrasonographic evidence of acute pancreatitis, that had increased thickness of the gastric wall and that were diagnosed with acute pancreatitis clinically. The gastric wall changes such as thickness, layering appearance, echogenicity, distribution of lesions, and perigastric changes were recorded. Serial ultrasonographic examination and histopathological findings were recorded if available. Results Mean gastric wall thickness was 9.9 ± 4.0 mm (SD). A complete loss of wall layering was observed in 2 dogs. Thickening of the submucosal layer was observed in 12 dogs, and 5 of them had concurrent muscularis layer thickening. The echogenicity of thickened submucosal layer was intermediate hyperechoic. Lacy appearances were present within the thickened submucosal layer in 7 dogs and in the muscularis layer of 1 dog. Thickening was focal in 12 dogs and adjacent to the diseased pancreas. Subsequent resolution of gastric wall thickening was observed in 3 dogs (range 3‐28 days) via follow‐up ultrasound. One dog underwent necropsy, and gastric wall edema was confirmed histopathologically. Conclusions and Clinical Importance Findings indicated that gastric wall thickening presumably because of edema could be a complication of acute pancreatitis.

Abstract
In acute pancreatitis (AP), kidney injury (KI) can occur. Urinalysis and some urinary biomarkers have been proposed as prognostic tools in human AP. The aim of the study was to evaluate urinalysis and urinary GGT-to-urinary creatinine (uGGT/uCr) in canine AP and their association with possible outcomes. AP diagnosis was based on clinical and laboratory parameters, abnormal SNAP® cPL™ test and compatible imaging. Urinary KI (uKI) was defined if dogs had urinary casts and/or proteinuria. Dogs (n = 70) were divided in survivors and non-survivors according to the 15-day outcome. Data were analyzed using statistical software. Seventy dogs were retrospectively included, of which 24 dogs (34%) died. uKI was detected in 36 dogs (37%) which was associated with mortality (p = 0.01, Odds ratio (OR) 3.9, 95% CI 1.3–11.56). Non-survivors showed higher dipstick bilirubin levels than survivors (p = 0.0022). By excluding active sediments, urine protein-to-creatinine ratio (UPC) ≥2 was associated with mortality (p = 0.001, OR 47.5, 95% CI 4–571.9). The uGGT/uCr was available in 40 dogs, although no association of this factor with any outcome was found. The UPC ≥2 can be a negative prognostic factor in canine AP and further studies on uGGT/uCr are warranted.

Abstract
A 4-year-old, neutered male Golden Retriever was presented with a 1-week history of weight loss, polyuria, and polydipsia. The diagnostic workup showed an increased ionized calcium concentration, mild increase in serum creatinine and urea concentration, and severe hyperlipasemia. A complete abdominal ultrasound revealed multiple hepatic nodules. A cytological diagnosis of malignant epithelial neoplasia, highly suggestive of bile duct adenocarcinoma was made. In order to confirm the presumptive diagnosis of hypercalcemia of malignancy due to the presence of a hepatic neoplasia, serum parathormone-related peptide concentration was measured, and the result revealed an increased concentration. The dog was hospitalized and received supportive treatments consisting of intravenous furosemide and fluid therapy. After ruling out lymphoma and hypoadrenocorticism, oral prednisone was initiated and ionized calcium concentration decreased gradually down to normal concentration after 7 days of hospitalization. Chemotherapy with intravenous epirubicin was initiated based on the cytological diagnosis. One month after diagnosis and due to the worsening of its clinical condition, the dog was humanely euthanized. Postmortem examination confirmed a cholangiocellular carcinoma. To our knowledge, this is the first report of malignant hypercalcemia associated with cholangiocellular carcinoma in a dog.

Abstract
Acute pancreatitis and acute kidney injury are well-documented comorbidities in human medicine. Dogs that develop acute kidney injury during hospitalization have significantly higher mortality rates than those that do not. The aim of this study was to evaluate the prevalence of acute kidney injury in dogs with acute pancreatitis and the prognostic value of various clinicopathological parameters. Cases of acute pancreatitis presented between January 2012 and June 2016 were identified. The diagnosis of acute pancreatitis was based on two or more of the following clinical signs: abdominal pain, diarrhea, vomiting or anorexia/hyporexia, no other abdominal extra-pancreatic diseases at abdominal ultrasound, and abnormal SNAP cPL test. Diagnosis of acute kidney injury was based on the guidelines of the International Renal Interest Society. Dogs were classified into survivors and non-survivors. Serum creatinine, urea, amylase, total calcium, total cholesterol, C-reactive protein, WBC and band neutrophils were evaluated at admission. Clinical severity index was calculated at admission. Clinical and clinicopathological data were compared between survivors and non-survivors. Sixty-five dogs with acute pancreatitis were assessed. Clinical severity index≥6.5 were associated with poor outcome (P=0.0011). Serum urea and creatinine concentrations at admission were significantly lower in survivors than non-survivors (P<0.0001 and P=0.0002, respectively). Acute kidney injury was diagnosed in 17/65 dogs (26.2%) and was associated with poor outcome (P<0.0001). Oligo-anuria was associated with poor outcome (P=0.0294). Increased clinical severity index and azotemia in dogs with acute pancreatitis were associated with an increased risk of mortality. Acute kidney injury may be a comorbidity of canine acute pancreatitis. The presence of oligo-anuria is associated with poor outcome.

Abstract
BACKGROUND Pancreatitis in cats (FP) has been increasingly diagnosed in recent years, but clinical studies of large numbers of affected cats are scarce. OBJECTIVES To describe a large cohort of cats with FP requiring hospitalization. ANIMALS One hundred and fifty-seven client-owned cats. METHODS Retrospective study, including cats diagnosed with pancreatitis based on sonographic evidence, positive SNAP feline pancreatic lipase immunoreactivity test results, increased 1,2-o-dilauryl-rac-glycerol-glutaric Acid-(6'-methylresorufin ester)-lipase activity, histopathology, or some combination of these. RESULTS One-hundred and twenty-two cats (77.7%) survived to discharge. Median time from onset of clinical signs to presentation was longer (P = .003) in nonsurvivors. Causes of FP included recent general anesthesia, trauma, hemodynamic compromise, and organophosphate intoxication, but most cases (86.6%) were idiopathic. Ultrasonographic findings consistent with pancreatitis were documented in 134 cats, including pancreatomegaly (81.3%), decreased (31.3%), or increased (14.9%) pancreatic echogenicity, extra-hepatic biliary tract dilatation (24%), and increased peri-pancreatic echogenicity (13%). Lethargy (P = .003), pleural effusion (P = .003), hypoglycemia (P = .007), ionized hypocalcemia (P = .016), azotemia (P = .014), parenteral nutrition administration (P = .013), and persistent anorexia during hospitalization (P = .001) were more frequent in nonsurvivors, whereas antibiotics were more frequently administered to survivors (P = .023). Nevertheless, when Bonferroni's correction for multiple comparisons was applied, none of the variables was statistically significant. CONCLUSIONS AND CLINICAL IMPORTANCE Previously unreported, clinically relevant, potential prognostic factors, including hypoglycemia, azotemia, parenteral nutrition, and withholding antibacterial treatment were identified in this exploratory study. These preliminary results should be examined further in confirmatory studies.

Abstract
OBJECTIVES Pancreatitis is a frequent disease in cats for which the ante-mortem diagnosis remains challenging. Feline pancreatic lipase immunoreactivity (fPLI) has been reported to have a high sensitivity for the diagnosis of pancreatitis. The aim of this study was to compare the rapid in-house test SNAP fPL with the standard test Spec fPL and to evaluate the use of SNAP fPL to diagnose pancreatitis in an emergency setting. METHODS fPLI of 111 cats with a clinical suspicion of pancreatitis was measured with both SNAP fPL and Spec fPL. Furthermore, clinical signs, haematological and biochemical changes, and abdominal ultrasound findings were recorded. RESULTS Seventy-eight of 111 cats (70.3%) were tested below the cut-off level for pancreatitis with SNAP, as well as Spec fPL, whereas 21/111 (18.9%) were tested with values above the cut-off level with both tests. In 12/111 (10.8%) cats the results were discordant. The comparison of both tests revealed an agreement of 78/80 (97.5%) when Spec fPL was ⩽3.5 μg/l (negative) and 18/20 (90%) when Spec fPL was ⩾5.4 μg/l (positive). The most common clinical signs in cats with suspected pancreatitis (n = 21) were lethargy (95.2%), reduced appetite and vomiting (90.5% each), dehydration (81.0%), diarrhoea (57.1%), abdominal pain and weight loss (47.6% each). Hyperglycaemia and hyperbilirubinaemia (85.7% each), increased aspartate transaminase (76.2%) and alanine transaminase (47.6%), leucocytosis (61.9%), lymphopenia (57.1%), decreased sodium and chloride (57.1% each), and increased urea (52.4%) were the most common abnormalities in blood work. CONCLUSIONS AND RELEVANCE Clinical signs, as well as routine blood-work changes, were non-specific and thus proved to be insufficient to diagnose pancreatitis. The combination of SNAP fPL and subsequent Spec fPL, if indicated, provided the opportunity to rule out or to diagnose pancreatitis with a higher certainty than previously known test methods. This study proved SNAP fPL to be a valuable tool to exclude or include pancreatitis in an emergency setting.

Abstract
Objectives Multidrug resistance 1 (MDR1) encodes a protein called P-glycoprotein (P-gp), which serves as an efflux pump membrane protein implicated in intestinal homeostasis and drug resistance. Cyclooxygenase-2 (COX2) is a key enzyme in the synthesis of proinflammatory prostaglandins, tumourigenesis and in mucosal defence. Despite the importance of MDR1 and COX2, changes in their mRNA levels have not been studied in cats with inflammatory bowel disease (IBD) and low-grade alimentary lymphoma (LGAL). The present study aimed to determine the mRNA levels of MDR1 and COX2 in cats with IBD and LGAL, and to evaluate their correlation with clinical signs, histological severity and between genes. Methods Cats diagnosed with IBD (n = 20) and LGAL (n = 9) between 2008 and 2015 were included in the current study. Three healthy animals composed the healthy control cats group in which endoscopy was performed immediately before the ovariohysterectomy. All duodenal biopsy samples were obtained by endoscopy. Feline chronic enteropathy activity index was calculated for all cases. IBD histopathology was classified according to severity. MDR1 and COX2 mRNA levels were determined by absolute reverse transcriptase-quantitative real-time PCR. Results Statistically significant differences were observed for MDR1 and COX2 mRNA levels between the IBD and LGAL groups. No correlations were observed between molecular gene expression, feline chronic enteropathy activity index and histological grading for IBD, and between MDR1 and COX2 genes. However, a positive statistically significant correlation was observed between MDR1 and COX2 expression in the duodenum of cats. Conclusions and relevance MDR1 and COX2 gene expression is increased in cats with LGAL compared with cats with IBD. The control group tended to have lower values than both diseased groups. These results suggest that these genes may be involved in the pathogenesis of IBD or LGAL in cats.

Abstract
The objectives of this study were fourfold: technical validation of a commercial canine 1,2-o-dilauryl-rac-glycero glutaric acid-(6’-methylresorufin) ester (DGGR) lipase assay, to calculate a reference interval for DGGR lipase by the indirect a posteriori method, to establish biological validity of the assay, and to assess agreement between DGGR lipase and specific canine pancreatic lipase (Spec cPL) assays. Dogs with histologically confirmed acute pancreatitis (n=3), chronic pancreatitis (n=8) and normal pancreatic tissue (n=7) with stored (−80°C) serum samples were identified. Relevant controls were selected. Precision, reproducibility and linearity of DGGR lipase, and the effect of sample haemolysis and freezing, were assessed. Sensitivity and specificity of DGGR lipase and Spec cPL were determined. Agreement between these two parameters was calculated using Cohen’s kappa coefficient (κ). The DGGR lipase assay demonstrated excellent precision, reproducibility and linearity. Sample haemolysis and storage at −80°C for 12 months did not influence the assay. DGGR lipase (>245IU/l) and Spec cPL (>400µg/l) both showed poor sensitivity but excellent specificity for acute pancreatitis, and poor to moderate sensitivity but excellent specificity for chronic pancreatitis. Substantial agreement (κ=0.679) was found between DGGR lipase and Spec cPL. The validated DGGR lipase assay had similar sensitivity and specificity for the diagnosis of acute and chronic pancreatitis to Spec cPL. DGGR lipase is a reliable alternative to Spec cPL for the diagnosis of pancreatitis.

Abstract
Background Renal replacement therapies can be life‐saving for dogs with severe acute kidney injury (AKI), however, comorbidities including pancreatitis might affect outcome. Hypothesis/Objectives To investigate the prevalence of pancreas‐specific lipase (Spec cPL) measurements consistent with pancreatitis (≥400 μg/L) in dogs undergoing intermittent hemodialysis (IHD) for treatment of AKI and to determine whether there were associations between 30‐days outcomes and Spec cPL measurements. Animals Fifty‐three client‐owned dogs presented to teaching hospitals between November 2008 and September 2016 that underwent IHD. Methods Retrospective medical record review from dogs that received IHD for management of AKI and also had a Spec cPL measurement. Association between survival, dialysis‐dependency, and Spec cPL measurements was assessed. Results Forty of 53 (76%) dogs were alive at 30‐days and 33/53(62%) had a Spec cPL result ≥400 μg/L. Spec cPL was not significantly different either between surviving (635.5 μg/L, range 29–1,001) and nonsurviving dogs (860 μg/L, range 56–1,001; P = 0.75) or between dialysis‐dependent (1,001 μg/L, range 177–1,001) and nondialysis‐dependent dogs (520 μg/L, range 29–1,001; P = 0.08). Spec cPL ≥400 μg/L was not significantly associated either with survival (P = 0.74) or dialysis‐dependency (P = 0.33). Conclusions and Clinical Importance Results revealed a high prevalence of Spec cPL ≥400 μg/L in dogs with AKI treated with IHD. No significant associations between Spec cPL and survival or dialysis‐dependency in dogs with AKI at 30 days were identified in the current study, however, the latter could be due to lack of power in this study.

Abstract
BACKGROUND The sensitivity, specificity, and agreement of 4 diagnostic assays (SNAP canine pancreatic lipase (cPL), specific cPL (Spec cPL), VetScan cPL Rapid Test, and Precision PSL) for pancreatitis in dogs have not been directly compared. HYPOTHESIS/OBJECTIVES To determine the level of agreement among each of the 4 assays and a clinical suspicion score, level of agreement among the assays, and sensitivity and specificity of each assay in a clinically relevant patient group. ANIMALS Fifty client-owned dogs with clinical signs of gastrointestinal disease. METHODS Prospective study. History, physical examination, complete blood count, serum biochemistry, abdominal ultrasound examination, and the 4 diagnostic assays for pancreatitis were performed. Intraclass correlation coefficients (ICC) were used to determine the level of agreement between each assay and a clinical suspicion score determined by a panel of 5 board-certified veterinary internists. RESULTS The ICC between the clinical suspicion score and the 4 assays were SNAP cPL, 0.61; Spec cPL, 0.68; VetScan cPL Rapid Test, 0.68; and Precision PSL, 0.60. The sensitivities of the assays ranged from 73.9 to 100.0%, whereas the specificities were SNAP cPL, 71.1-77.8%; Spec cPL, 74.1-81.1%; VetScan cPL Rapid Test, 76.9-83.8%; and Precision PSL, 64.0-74.3%. CONCLUSIONS AND CLINICAL IMPORTANCE A good to excellent level of agreement was demonstrated among the 4 assays. The previously unreported sensitivity and specificity of the VetScan cPL Rapid Test were 73.9-83.3% and 76.9-83.8%, respectively. Results of any of the 4 diagnostic assays alone, in the absence of supporting clinical findings, are insufficient to establish a diagnosis of clinical pancreatitis in dogs.

Negative pressure therapy versus passive open abdominal drainage for the treatment of septic peritonitis in dogs: A randomized, prospective study. Vet Surg 2017; 46:1086-1097.

Abstract
OBJECTIVE To compare passive open abdominal drainage (POAD) and negative-pressure abdominal drainage (NPAD) using the ABThera™ system in the treatment of septic peritonitis. STUDY DESIGN Randomized prospective clinical trial. ANIMALS Dogs (n = 16) with septic peritonitis. METHODS Dogs with septic peritonitis were randomly assigned to one of two treatment protocols: NPAD versus POAD. Anesthesia time, operating time, duration of drainage, costs, survival, and complications were compared between techniques. Hematological and biochemical parameters in blood and abdominal fluid, and histopathological findings of omentum and abdominal wall tissue samples were compared between NPAD and POAD at time of initial surgery and at time of closure. RESULTS Overall survival was 81%. Treatment costs, anesthesia and operating time, drainage time, survival, and postoperative complications were similar between techniques. Loss of total plasma protein and decreased inflammation-related factors in abdominal fluid at time of closure were noted in all patients. Neutrophilic inflammation was greater in abdominal wall samples after NPAD. POAD patients showed discomfort during bandage changes and had frequent leakage of abdominal fluid outside of the bandage. CONCLUSION NPAD is an effective alternative to POAD for treatment of septic peritonitis, based on costs and survival. NPAD resulted in less abdominal fluid leakage, and evidence of superior healing on histological evaluation of abdominal tissues.

J Small Anim Pract 2016; 57:690-697.

Abstract
BACKGROUND Idiopathic purulent mesenteric lymphadenitis or lymph node abscessation, even though rare in dogs, are important diseases in which rapid diagnosis and treatment is critical. This study aimed to characterise the typical features of these conditions in dogs. MATERIAL AND METHODS Archived records from 2005 to 2015 were retrospectively evaluated for the occurrence of idiopathic purulent mesenteric lymphadenitis or lymph node abscesses in dogs. History, physical and clinicopathological abnormalities, diagnostic tests performed, treatment and outcome were reviewed. RESULTS A total of 14 cases with histopathologic and/or cytologic confirmation were identified. Typically, there were gastrointestinal signs including abdominal pain and elevated body temperature. Blood analysis revealed non-specific inflammatory changes including elevated C-reactive protein. Half of the bacterial cultures from lymph nodes showed growth of various bacteria. A primary cause was not identified in any case. Out of 14 cases, 10 cases underwent surgery and all dogs were discharged from the hospital. Three suffered from a relapse between 1 and 5 months after discharge but were successfully managed with antibiotics. CONCLUSION AND CLINICAL RELEVANCE Idiopathic purulent mesenteric lymphadenitis or lymph node abscessation are infrequent but clinically important diseases. Surgical, symptomatic and antibiotic treatment led to resolution of clinical signs in the evaluated cases. Thorough and standardised diagnostic workup and treatment of future cases are necessary to investigate possible pathogeneses and optimal therapeutic options. Outcome was favourable overall.
