Pancreatitis Flashcards
What is the prominent feature of pancreatic pathology and what are associated features
Back pain
Nausea and vomiting
What is the basic problem in acute pancreatitis
Autodigestion of pancreatic tissue by it’s own enzymes
What triggers this autodigestion of pancreatic tissue
- Obstruction to flow of pancreatic juice
2. Direct damage to pancreatic ductal epithelium from ischemia, drugs, toxins, trauma or viral infections
Acute pancreatitis with pancreatic necrosis is known as
Hemorrhagic pancreatitis
5% of cases of acute pancreatitis are complicated by
Clinically significant pseudocyst
What are the common cause of acute pancreatitis
GETSMASHED PNEUMONIC
Gallstones Ethanol Trauma Steroids Mumps Autoimmune Scorpion bites Hyperlipidaemia/hypercalcaemia ERCP Drugs : SAND = Steroids and sulphonamides ,azathioprine ,NSAIDs and diuretics
Which blood investigations would you require for Acute pancreatitis
- Serum amylase: diagnostic if elevated >5×
- FBC
- Blood glucose
- ABG
- Clotting profile
- Urea and creatinine
- Electrolytes : calcium etc
- LFTs
In which scenarios would amylase not be increased in acute pancreatitis
- When the condition has already been present for a few days
- Where the attack occurs against the background of chronic pancreatitis
How does the high risk patient present clinically
- Dyspnoea / Tachypnoea
2. Shiny face
What is the role of radiological investigations in pancreatitis and which ones you would require
-To exclude other acute abdominal conditions like free air under the diaphragm and bowel obstruction
- Abdominal Xrays , supine and erect
- Chest xray
- ultrasound but not reliable
- CT scan : after 10 to 14 days when the inflammation has resolved or earlier on when the diagnosis is inconclusive
What are finding on Xrays that would support the diagnosis of acute pancreatitis (4)
- Left sided pleural effusion
- calcifications in the vicinity of the pancreas : indicative of underlying chronic pancreatitis
- Sentinel loop = single , dilated loop in the left upper abdomen
- Colon cut off sign
What is required for the diagnosis of Acute Pancreatitis
- Epigastric pain of acute onset which is severe and persistent ,often radiating to the back
- Serum lipase/amylase activity of atleast 3× greater than the upper limit of normal
- Characteristic findings of acute pancreatitis on CET or MRI or trans abdominal ultrasound
What alleviates the pain
Sitting up and leaning foward alleviates the pain and they are uncomfortable lying supine
Other sources of elevated amylase
- PUD
- Intestinal obstruction
- Perforated bowel
- cholecystitis
- Cholangitis
- Appendicitis
- Pancreatic Cancer
- Renal failure
- ARDS
- DKA
