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

• Most dogs with pancreatitis DO NOT
have fasting hyperlipidemia

• TLI
– Sensitivity ~ 35%

WHAT IS THE BEST WAY
TO DIAGNOSE CANINE
ACUTE PANCREATITIS?
Patient with possible acute pancreatitis
Find evidence suggestive
of pancreatitis
Eliminate diseases
mimicking pancreatitis
Imaging (ultrasound)
Chemistry panel
Abdominal imaging
cPLI

All things being equal, try
to avoid surgery
THE REAL PROBLEM IS
THAT ACUTE PANCREATITIS
CAN PRESENT IN SO MANY
DIFFERENT WAYS THAT
YOU DON’T EVEN SUSPECT
IT INITIALLY

PANCREATITIS CAN:
a) make no abdominal effusion
b) make a little abdominal effusion
c) make a massive abdominal
effusion
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
SYSTEMIC INFLAMMATORY
RESPONSE SYNDROME –
used to be called “Septic
shock”
SYSTEMIC INFLAMMATORY
RESPONSE SYNDROME –
inadequate perfusion of the
body tissues because of an
exaggerated inflammatory
response

Systemic
circulation
WHAT CAN HAPPEN
Inflammatory cytokines
Lymph nodes
Systemic
circulation
EARLY -- SIRS
Mild uneven vasodilatation
“High output” shock
Bright red mucus membranes
Fast capillary refill time
Bounding pulses
Tachycardia
LATE -- SIRS
Severe peripheral vasodilatation +
poor cardiac contractility
“Low output” shock
Pale mucus membranes
Weak pulses
Slow refill time
