Abdominal Pain Flashcards
What are two most significant properties of pain
Site
Character
What framework do we use to ask patients about pain?
- Site- where is it?
- Onset- has it come on suddenly or gradually?
- Character- what is the pain like? Is it burning? Colicky (sharp, localised)? Aching?
- Radiation- where does it go to?
- Association- is it associated with vomiting? Fever?
- Time course- have they had that pain before?
- Exacerbating or relieving factors- what makes it better? What makes it worse?
- Severity- how bad is it e.g. /10?
- What organ structures are found at the transpyloric plane?
L1
- Pylorus of stomach
- Neck of pancreas
- Fundus of gallbladder
- Renal hilum of left kidney (right kidney is pushed down a bit by liver)
- Duodenojejunal flexure
- End of spinal cord in adult
What organ structures are found at the subcostal plane and supracristal plane respectively?
Subcostal plane- L3
- Origin of inferior mesenteric artery
Supracristal plane- L4
- Bifurcation of the aorta
Forget
Innervated by T5-T9
Pain is site if epigastrium
Midgut
Innervated by T10-T11
Pain site of umbilicus
Hindgut
Innervated by L1-L2
Pain is site of hypogastrium
Parietal vs visceral peritoneum
Parietal covers the abdominal wall anteriorily
Visceral covers organs
What nerves supply the parietal peritoneum?
Phrenic nerves that supply sensation from central tendon to diaphragm → C3, C4, C5
C3 and 5 Innervated right shoulder so patients can present with right shoulder pain when something’s wrong
Segmental innervating from T5-L2
What nerves supply visceral peritoneum
- Parasympathetic supply from vagus nerve
- Parasympathetic supply from S2-4
- Sympathetic chain goes T1-12 and L1-2
What kind of pain does inflammation cause
Constant aching pain
Made worse by movement
Persists until inflammation subsides
What pain does obstruction cause
- Colicky ‘gripping’ pain
- Fluctuates in severity
- Patient moves to try and get comfortable
- There has been prolonged obstruction of a hollow viscus that has caused distension
- This is different from ache of inflammation and isn’t colicky
- There may be impending ischaemia
What kind of pain does you find in the ureter liver biliary colic spleen kidney small or large bowel
- UreterColicky
- LiverConstant e.g. could be hepatitis or liver abscess
Colicky pain usually in tubular structures and is crampy
- Biliary-colic
Colicky e.g. stone trying to get through duct like bile duct
- SpleenConstant e.g. splenic abscess or rupture
- KidneyConstant e.g. pyelonephritis or abscess
- Small or large bowelColicky
Where does gallbladder (right hypochondriac region) pain radiate?
Through to the back and right- this happens in 50% of cases
-
Where does stomach, duodenum, pancreas (epigastrium) pain radiate?
- Straight through to back- especially because pancreas and duodenum are retroperitoneal
- People with pancreatic cancer present with back pain because tumour infiltrates posteriorly
