Pancreatic disease Flashcards
Diagnosis of acute pancreatitis requires?
> 2 out of 3
- Persistent, severe epigastric pain radiating to the back
- Serum lipase/ amylase >X3 upper limit of normal
- Characteristic finding on CECT/ MRI/ trans-abdominal ultrasound
Causes of acute pancreatitis
> I GET SMASHEd
- Idiopathic
- Gallstones
- Ethanol abuse
- Trauma
- Steroids
- Mumps virus
- Autoimmune disease
- Scorpion stings
- Hypertriglyceridemia & hypercalcemia
- ERCP
Investigation for acute pancreatitis
> Diagnostic
- Serum amylase >3x upper limit [Normal = 30-100 U/L]
- Serum lipase >3x upper limit [Normal = 10-140 U/L]
> Underlying etiology
- LFT (elevated ALT - gallstone pancreatitis; elevated AST - Ranson and Glasgow)
- Ultrasound abdomen (dilated CBD/ gallstone)
- Ca/ Mg/ PO4 (hypercalcemia)
- Fasting lipid (hyperlipidemia)
> Imaging
- Erect CXR (air under diaphragm)
- Supine AXR (localized ileus)
- MRCP (visualizing cholelithiasis, choledocholithiasis, anomalies of the pancreatic and common bile duct)
Management of acute pancreatitis
> Supportive treatment - 90% response
- Keep NBM
- IV fluid resuscitation
- Pain management (Tramadol)
- NG tube insertion, anti-emetics
- Antibiotic management
> Management etiology
- Avoid alcohol, control hyperlipidemia
- ERCP + endoscopic sphincterotomy (for severe biliary pancreatitis)
- Cholecystectomy
Complication of acute pancreatitis
> Local
- Acute fluid collection
- Pseudocyst
- Pancreatic abscess
- Chronic pancreatitis
- Exocrine/ endocrine insufficiency
> Systemic
- Peritoneal sepsis
- Pleura effusion
- Shock
- Multiple organ failure
- Hypocalcemia, hyper/ hypoglycemia
Clinical features head/ periampullary of pancreas Ca
- Obstructive jaundice
- NV
- LOW
- Recurrent pancreatitis
Clinical features pancreatic body/ tail Ca
- Epigastric pain
- Malaise, LOW, LOA
- Nausea
- Exocrine insufficiency
- Trousseau’s sign
Investigaiton for pancreatic Ca
> Imaging
- Contrast CT
- Endoscopic US + FNA biopsy
- ERCP
> Lab
- CA 19-9
- Serum bilirubin
- Serum alkaline phosphatase
- AST/ ALT
> Staging
- CT TAP
- Endoscopic US
- Bone scan
- Staging laparoscopy
Management for pancreatic Ca
> Head/ Uncinate process
- Whipple’s operation
> Body/ Tail
- Distal subtotal pancreatectomy +- splenectomy
> Entire glands
- Total pancreatectomy
Absolute contraindication for resection
- Presence of metastases in liver, peritoneum, omentum, or extra abdominal site
- Encasement (>1/2 circumference) or occlusion of SMA
Describe Whipple procedure
> Removal of
- Pancreatic head
- Duodenum
- Proximal 15cm of jejunum
- Common bile duct
- Gallbladder
- Partial gastrectomy
> Reconstruciton
- Pancreatojejunostomy
- Hepaticojejunostomy
- Gastrojejunostomy
Post-Op care Whipple procedure
- Most do not required ICU monitoring
- Majority discharge within 7-10 days of operation
- Nutritional support (D1-2: clear liquid; D3-4: regular diet)
- Drain management (close suction drain; removed once tolerating regular diet)
Ranson/ Glasgow criteria component
> PANCREAS
- PaO2
- Age>55
- Neutrophils (WBC)
- Calcium
- Renal (BUN)
- Enzyme (AST + LDH)
- Albumin
- Sugar (Glucose)
> Replace Albumin with HepatoBiliary Failure in Ranson
- Hematocrit
- Base deficit
- Fluid sequestration
Definition of chronic pancreatitis
- Continuing inflammatory disease of the pancreas characterized by irreversible morphological change typically causing pain and/or permanent loss of function
What is pseudocyst
- Walled off fluid collection that are more common in chronic pancreatitis than acute
- Takes at least 4 weeks to develop
- Caused by inflammation and subsequent damage of the pancreatic ducts leading to extravasation and accumulation of pancreatic fluid
