4 Physical Examination Anterior abdominal pain Icterus Profuse ascites Fever SQ abscesses

6 WHICH CBC(S) IS/ARE FROM DOG(S) WITH ACUTE PANCREATITIS?

9 Clinical Pathology An anorexic, vomiting dog with fasting hyperlipidemia probably has acute pancreatitis

10 Clinical Pathology An anorexic, vomiting dog with fasting hyperlipidemia probably has acute pancreatitis Most dogs with pancreatitis DO NOT have fasting hyperlipidemia

11 Clinical Pathology Amylase/Lipase – Sensitivity ~ 50% – Specificity ~ 50% TLI – Sensitivity ~ 35%

12 Clinical Pathology cPLI – Sensitivity ~ 80-85%

13 Sig: 7 yr M Boxer X CC: Anorexia/Vomiting HPI: Started 1 week ago snap PLI = pancreatitis Dog died despite therapy: Everything normal on gross necropsy

24 Diagnostics cPLI – Sensitivity ~ 80% Abdominal ultrasound – Sensitivity probably ranges from 40% to about 65%

25 Diagnostics cPLI – Sensitivity ~ 80% Abdominal ultrasound – Sensitivity probably ranges from 40% to about 65% because clinicians rarely repeat the ultrasound

26

27 Diagnostics cPLI – Sensitivity ~ 80% Abdominal ultrasound – Sensitivity probably ranges from 40% to about 65% – Findings can change within hours...

28 WHAT IS THE BEST WAY TO DIAGNOSE CANINE ACUTE PANCREATITIS?

29

30 All things being equal, try to avoid surgery

31 THE REAL PROBLEM IS THAT ACUTE PANCREATITIS CAN PRESENT IN SO MANY DIFFERENT WAYS THAT YOU DON’T EVEN SUSPECT IT INITIALLY

32 TAMU#88267 Sig: 7 yr M Sheltie CC: Vomiting HPI: Began 5 weeks ago Partial anorexia, vomits phlegm or bile once daily Dog otherwise pretty healthy PE: No significant abnormalities

33 TAMU#88267 PCV =37% (35-55) WBC =21,800/ul (6,-16,000) Segs =20,274/ul (4,-14,000) Lymphs =840/ul (1, ,000) Platelets =255,000/ul (200, - 500,000)

34 TAMU#88267 Creatinine =2.0 mg/dl (< 2.0) BUN =36 mg/dl (8-29) Total protein =4.7 gm/dl ( ) Albumin =1.7 gm/dl ( ) ALT =10 U/L (< 130) SAP =31 U/L (< 147) Bilirubin =0.4 mg/dl (< 1.0) Urine:1.015 with 4+ protein

39 TAMU# Sig: 9 yr M(c) Pug CC: Vomiting, yellow scleras HPI: Feeling bad 12 days ago Started vomiting, responded to fluid therapy, but became ill again when started feeding it Dog’s eyes turned yellow PE: Scleras yellow

40 TAMU# PCV =40% (35-55) WBC =11,500/ul (6,-14,000) Segs =9,890/ul (4,-12,000) Lymphs =460/ul (1,-4,000) Eos =230/ul (100-1,250) Platelets =470,000/ul (200,-500,000)

41 TAMU# BUN =4 mg/dl (8-29) Creatinine =0.7 mg/dl (< 2.0) Glucose =95 mg/dl (75-133) Potassium =3.6 mEq/L ( ) Cholesterol =597 mg/dl ( ) Albumin =2.9 gm/dl ( ) ALT =1,691 IU/L (< 130) SAP =3,134 IU/L (< 147) Bilirubin =4.5 mg/dl (0-0.8)

46 TAMU # Sig: 9 yr F(s) Dalmation CC: Vomiting/diarrhea HPI: Vomiting food/bile 6-8X in 2 weeks Diarrhea constantly for 2 weeks Decreased appetite for 10 days, anorexia for 5 days PE: T = F, HR = 102/min

47 TAMU # PCV =35.5% (35-55) WBC =21,700/ul (6,-14,000) Segs =15,200/ul (4,-12,000) Bands =630/ul (< 500) Lymphs =1,400/ul (1,-4,000) Platelets =568,000/ul (200,-500,000)

49 TAMU # Abdominal ultrasound: “… Small amount of anechoic effusion between liver lobes and around urinary bladder. Fine Needle Aspirate reveals turbid yellow tan fluid.”

50 TAMU # Abdominal fluid: WBC =153,000/ul RBC =0/ul Total protein =4.6 gm/dl 90% nondegenerate neutrophils 8% macrophages, vaculated “Suppurative exudate”

51

52 TAMU # “Chronic necrotizing and fibrosing interstitial pancreatitis with multifocal... suppuration and hemorrhage and peritonitis...”

53 Sterile pancreatitis versus Septic peritonitis

54 Abdominal fluid TP gm/dl WBC/ul 15,059153, ,200 RBC/ul 91,112030,00083,700

55 PANCREATITIS CAN: a) make no abdominal effusion b) make a little abdominal effusion c) make a massive abdominal effusion

56 Pancreatitis can present as: acute vomiting with abdominal pain chronic, low grade vomiting/anorexia (abscess) icterus (biliary tract obstruction) ascites (minimal, little or lots) acute abdomen (looks just like septic peritonitis) SIRS (looks like septic shock) any really sick animal

57 SYSTEMIC INFLAMMATORY RESPONSE SYNDROME – used to be called “Septic shock”

58 SYSTEMIC INFLAMMATORY RESPONSE SYNDROME – inadequate perfusion of the body tissues because of an exaggerated inflammatory response

59 WHAT IS SUPPOSED TO HAPPEN Bacterial toxin, inflammatory cytokines Lymph nodes, hepatic macrophages Systemic circulation

63 WHAT IS SUPPOSED TO HAPPEN Bacterial toxin, inflammatory cytokines Lymph nodes, hepatic macrophages Systemic circulation

64 Inflammatory cytokines Lymph nodes Systemic circulation WHAT CAN HAPPEN

65 EARLY -- SIRS Mild uneven vasodilatation “High output” shock Bright red mucus membranes Fast capillary refill time Bounding pulses Tachycardia

66

67 LATE -- SIRS Severe peripheral vasodilatation + poor cardiac contractility “Low output” shock Pale mucus membranes Weak pulses Slow refill time

68 THERAPY FOR PANCREATITIS Only supportive and symptomatic NPO versus early feeding

69 THERAPY FOR PANCREATITIS Only supportive and symptomatic NPO versus early feeding Fluid therapy Crystalloids Plasma Colloids Total/partial parenteral nutrition

70 THERAPY FOR PANCREATITIS Only supportive and symptomatic NPO versus early feeding Fluid therapy Crystalloids Plasma Colloids Jejunostomy feeding (PEG-J, Nasal J, regular J)

71 THERAPY FOR PANCREATITIS Only supportive and symptomatic NPO versus early feeding Fluid therapy Crystalloids Plasma Colloids Nutrition Analgesics

72 THERAPY FOR PANCREATITIS Only supportive and symptomatic NPO versus early feeding Fluid therapy Analgesics Anti-emetics: if vomiting makes it hard to maintain hydration or patient is really miserable Proton-pump inhibitors: the same

73 OTHER POSSIBILITIES Antibiotics – “Regular” pancreatitis – SIRS

74 OTHER POSSIBILITIES Antibiotics Heparin

75 OTHER POSSIBILITIES Antibiotics Heparin Steroids – Critical Care Medicine 36: , 2008
