pancreatitis Flashcards
rfs and pfs for acute pancreatitis
- RFs
- Smoking
- High dietary glycemic load Abdominal adiposity
- ↑ Age and obesity
- Increases changes of more severe course
- PFs
- high vegetable/fiber diet
- statins (bar simvastatin which increases it)
Assessment of Severity
- Ranson Criteria
- Sequential Organ Failure Assessment (SOFA)
- Modified Marshall scoring system
- APACHE II
- Bedside Index for Severity in Acute Pancreatitis (BISAP)
- Presence of SIRS (Systemic Inflammatory Response Syndrome) and Elevated BUN on admission with a rise in BUN w/in first 24 hours of hospitalization
- Early rise in serum levels of neutrophil gelatinase-associated lipocalin has been proposed as a marker of severe acute pancreatitis
- HAPS (“Harmless acute pancreatitis score”)
- Revised Atlanta classification (Mild, Moderate, Severe)
- CT Grade of Severity Index for Acute Pancreatitis
ranson criteria and apache II score
ranson: 1-2 (1% mortality); 3-4 (16% m); 5-6 (40%); 7-8 (100%)
physiological score + age + chronic health points = APACHE II score
RISK Factors for Severe Acute Pancreatitis with high levels of fluid accumulation
Younger age
Alcohol etiology
Higher hematocrit value
Higher serum glucose w/in 48 hrs of hospital admission
SIRS w/in 48 hrs of hospital admission
which criteria predicts a severe course complicated by necrosis, and what value corresponds to this in the criteria?
3 or more aspects of the criteria, ranson criteria, 60-80 sensitivity
Revised Atlanta Criteria
mild AP: no oran failure, no complications
moderate AP: transient organ failure < 48 hrs with +/- complications
severe: organ failure lasting longer than 48 hrs +
Tx of Mild Acute Pancreatitis
80% resolve without complications
Lots of fluids: 1/3 of a 72 hr fluid administration needs to be delivered to the patient in the first 24 hours of their presentation.
Let the pancreas rest: NPO, bed rest, NG suction for the ileus
Fluid administration prevents SIRS (systemic inflammatory response syndrome) but may induce ARDS (acute respiratory distress)
opioids for pain; when pain relieved, begin oral administration of food/liq
tx of severe pancreatitis
FFP for coagulopathy
Serum Albumin infusions to restore albumin
calcium glucoronate for hypocalcemia with tetany
I GET SMASHED
Idiopathic
Gallstone obstruction
Ethanol abuse
Trauma
Steroid abuse
Mumps
Autoimmune disorders
Scorpoion sting
Endoscopic Retrograde Colangiopancreatography (ERCP)
Hypertriglyceridemia/Hypercalcemia
SAPE
sentinel Acute Pancreatitis Event
hypothesis that a single initiating event damages the pancreas and leads to later chronic pancreatitis via necrosis-fibrosis
Labs for acute pancreatitis
increased serum amylase and lipase: normal doesnt exclude diagonosis
increased total bilirubin (direct) and alkaline phosphatase (if pancreas is compressing the bile duct): normal does not exclude diagnosis
vitamin deficiencies but uncomplicated (too fast)
glycosuria
autoimmune condition pancreatitis: IgG4/ANC/Ab-carbonic anhydrase II and lactoferrin/
Shows lymphoplasmacytic inflammatory infiltrate with characteristic IgG4 immunostaining
Autoimmune pancreatitis
Elevated IgG4
Elevated ANA
Ab to lactoferrin and carbonic anhydrase II
Pancreatic biopsy
Panceatic function tests
- Trypsinogen
- level is low in insufficiency (<20 ng/ml) causes steatorrhea
- Fecal elastase
- low in insufficiency (<100 mcg/gram stool)
- Pancreatic malabsorption
- when enzyme secretion is <5-10% takes >5 years
- Stimulation tests
- Cholecystokinin/secretin
Imaging in Pancreatitis
X-ray: calcifications
CT: more detailed calcifications, plus ductal dilations, atrophy or heterogeneity of the gland. “tumfactive chronic pancreatitis”- concern for pancreatic cancer
ERCP: most detailed for calcifications, ductal dilations, stones, strictures, pseudocyst. Rarely used alone for diagnosis. Results may be normal with minimal change chronic pancreatitis.
MRCP:
Can enhance imaging with secretin
