Inflammation and tumours of the pancreas Flashcards
What arteries supply the pancreas
Gatroduodenal gives off a branch - anterior and posterior superior pancreatiduodenal
Superior mesenteric gives off pancreatlduodenal
branches off splenic
What is the accessory pancreatic duct
Extra duct other than the pancreatic that joins the pancreas to the duodenum in a slightly different place
endocrine function
secretion of insulin and glucagon
Exocrine function
secretion of digestive enzymes
Pancreatic fluid regulation
secretions regulated by vagus nerve and gastrin levels
What do acing cells secrete
protease
Pancreatic lipase
Pancreatic amylase
Other enzyme
What how are 80% of acute pancreatitis treated
analgesia and IV fluids
I GET SMASHED
I-idiopathic
G-gallstones
E- ethanol
T-trauma
S-steriods M-mumps and malignancy A- autoimmune conditions S- scorpion bite H- hypercalceamia and hypolipidemia E-ERCP -causes 3% of cases D-Drugs
Pancreatic due to autoddigestion of pancreas
Pancreatic enzymes are released and activated
these auto digest pancreas
Four stages of auto digestion pancreatitis
Hypovolaemic shock -oedema and fluid shits
Autodigestion of blood vessels - retroperitoneal haemorrhage
Infarction due to compromised blood supply - pancreatic neucrosis

Clinical presentation of pancreatitis
Acute onset of epigastric pain Radiating through to back Very severe Double over Nausea and vomiting Jaundice
Trigger identified- gallstones, ERCP
Examination findings for pancreatitis
Upper abdominal tenderness
Soft
Normal bowel sounds
Fullness in epigastrium
Classical signs of pancreatitis
Erythema abinge (hot water bottle rash) Grey turners sign (flanks) Cullens sign (umbilical)
Initial investigations for pancreatitis
IV access Bloods -FBC & coagulation -Us&Es, LFTs, calcium, glucose, amylase/lipase, CRP & lactate ABGs -hypoxia -acute respiratory distress syndrome
Xray
Ultrasouns
CT- to look for severity/complications
Why do patients with pancreatitis get pleural effusions
They fail to inflate their lungs properly cause of pain
