18. Disorders of the pancreas Flashcards
What is the difference between diagnosis and etiology?
Diagnosis refers to identifying a disease or condition, while etiology refers to identifying the cause of the disease or condition.
What tests are needed for a patient with AP?
- Measurements of inflammatory markers (CRP, WBC), liver enzymes, TG, cholesterol and calcium
- Pancreatic imaging
- Determining BISAP score
- Genetic testing following second episode of AP
What is the BISAP score used for severity prediction in acute pancreatitis?
Bedside Index for Severity in Acute Pancreatitis score, which includes
- serum urea level,
- impaired mental state,
- SIRS criteria,
- age > 60,
- presence of hydrothorax.
What is the mortality rate for patients with a BISAP score less than 2?
Less than 2%.
What are the recommended measurements when diagnosing AP?
Inflammatory markers (CRP, WBC, PCT), liver enzymes, triglyceride, cholesterol, and calcium.
What are some common mistakes when using early CT scans in acute pancreatitis?
- Early CT scans (in the first 72-96 hours) may be false negative or underscore acute pancreatitis,
- mCTSI may misdiagnose severity due to subjective components of criteria,
- there may be confusion between “walled-off necrosis” and pseudocysts.
Why is fluid resuscitation important in acute pancreatitis?
Patients with AP are hypovolemic due to vomiting, decreased oral fluid intake, sweating, and loss of fluid into a third water-space.
What are the three steps recommended for fluid resuscitation therapy?
- Start with rapid 5-10ml/bodykg/h infusion,
- Ringer lactate (2500-3000ml) is the optimal choice for securing daily fluid intake,
- Monitor the efficacy of fluid resuscitation (electrolytes, BUN, hematocrit), physical parameters (pulse, MAP, urine)!
What happens to CRP and WBC levels in the first 3 days of acute pancreatitis?
CRP and WBC levels rise due to the sterile inflammation in the first 3 days of acute pancreatitis.
What are the common mistakes in initiating AB therapy for acute pancreatitis?
1) Initiating AB therapy as a response to rising CRP and WBC in the first days of admission.
2) Indicating prophylactic antibiotics for necrosis.
What is the only parameter really correlating with infection?
PCT (specifically bacterial infection)
What are some common mistakes in feeding patients with acute pancreatitis?
Lack of feeding, fear of gastric feeding, and postponing re-feeding until the normalization of laboratory studies.
Is enteral nutrition recommended for acute pancreatitis?
Yes, enteral nutrition is recommended and very rarely contraindicated in acute pancreatitis.
What is the optimal timing of ERCP in acute biliary pancreatitis (ABP)?
Urgent ERCP (<24h) is recommended ONLY if ABP is associated with acute cholangitis.
What should be done if biliary stones or obstruction cannot be confirmed with conventional imaging?
Non-invasive methods such as MRCP or EUS should be used.
