Pancreas Flashcards
What is the most common congenital anomaly of pancreas
Pancreas divisum.
Failure of fusion of dorsal and ventral pancreatic buds
Which structures Opens at ampulla of vater.
Main pancreatic duct (Wirsung duct) + CBD opening
Distal part of accessory duct of Santorini
Opens at minor papilla.
What is Annular pancreas :
• malrotation of the ventral bud of pancreas -> Encircles 2ndpart of duodenum -> Annular pancreas.
C/f of annular pancreas
Non bilious vomiting
Which sign is seen on X-Ray of annular pancreas
Double bubble sign (also seen in duodenal atresia)
IOC and Management of duodenal atresia
IOC : CECT abdomen
Management: Duodenoduodenostomy (DD)
Sphincter of oddi made of how many sphincter
4 Sphincter
Which classification is used for sphincter of oddi dysfunction
Milwaukke classification
MCC of acute pancreatitis
Gall stone induced
(2nd most is alcohol)
MCC of acute pancreatitis in children
Blunt trauma to abdomen
Pathophysiology of pancreatitis
Any stimulus -> Increased calcium -> co-localization of zymogen and lysosome -> Fuse -> Trypsinogen releases cathepsin B -> Activate trypsin -> Acinar death :
Inflammatory cascade.
Inflammatory mediators of pancreatitis are
IL I, IL 6, TNF alpha, IL 10.
CF of acute pancreatitis
- Pain epigastrium radiating to back, relieved on bending forward.
- out of proportion symptoms.
- Features of peritonitis: Guarding, rigidity, rebound tenderness (severe pancreatitis)
Sings in acute hemorrhagic pancreatitis
Cullen’s sign ;
Grey turner sign ;
Fox sign :
Describe Cullen’s sign
Discoloration around umbilicus.
Grey Turner’s sign
Discoloration in flanks.
• Fox sign:
Discoloration in inguinal region.
Discoloration is due to
Retroperitoneal bleeding
Diagnosis of pancreatitis is made by
I. Abdominal pain consistent with pancreatitis.
2. >/= 3 fold high elevated serum amylase/lipase above upper laboratory levels.
3. Characteristic findings of pancreatitis by imaging.
If any 2 of the above positive -> Pancreatitis.
Serum amylase in acute pancreatitis is
Rises quickly, shorter half life, sensitive.
Serum lipase in acute pancreatitis is
Rises gradually, longer half life, more specific. Amylase and lipase not predictive of severity of attack.
IOC For Acute Pancreatitis
CECT abdomen.
• Done after 72 hours after onset of symptoms.
• If within 72 hours, it can underestimate the severity.
• Portal venous phase in CECT
(65-70 seconds after contrast): most sensitive for pancreatitic necrosis.
Radiological signs in acute pancreatitis
Colon cut off sign (ileus) on X-ray.
Sentinel loop sign (focal dilated jejunal loop).
Gasless abdomen (also seen in acute gastroenteritis, diarrhea).
Glasgow criteria is valid for
Both gallstone and alcohol induced pancreatitis.
>/= 3 severe pancreatitis
Ranson score is valid for
Alcohol induced pancreatitis.
Glasgow criteria includes
PANCREAS
It is scored through the mnemonic, pancreas:
• P: PaO2 < 8 KPa.
• A: Age > 55 years old
• N: Neutrophilia: WCC >15 x 10^9/L.
• C : Calcium < 2 mmol/L.
• R: Renal function, urea > 16 mmol/L.
• E: Enzymes : LDH > 6OOiu/L ;
AST > 200iu/L.
• A : Albumin < 3.2g/L (serum).
• S: Sugar: Blood glucose >10 mmol/L.
BISAP Score includes
BUN > 25 mg / dl
Impaired mental status
SIRS
Age >60
Pleural effusions
> /=3 indicates severe pancreatitis
Other markers for pancreatitis
- C-reactive protein > 150 IU/L : Severe pancreatitis.
- APACHE system: Acute physiology and chronic health evaluation score (>/= 8 : Severe pancreatitis).
- APACHE O score: (0-obesity).
- HAPS score harmless acute pancreatitis score).
- modified marshall’s score:
• Tells about organ dysfunction.
• >/= 2: Organ dysfunction. - Balthazar grading : Best scoring system for acute pancreatitis (CT severity index).
• >/= 6: severe pancreatitis.
What is pancreatic ascetics
Disruption of pancreatic duct
What is the most common vessel involved in vascular complication of pancreatic necrosis
Splenic artery
What is chronic pancreatitis?
Repeated attacks of pancreatitis -> Fibrosis + chronic inflammation -> irreversible damage to pancreatic parenchyma (single/multiple episodes).
