Abdominal Pain Flashcards
Define SOCRATES
Site, Onset, Character, Radiation, Associations, Time Course, Exacerbating/Relieving Factors, Severity
Define the abdominopelvic regions
Right hypochondriac region, Epigastric region, Left hypochondriac region, Right lumbar region, Umbilical region, Left lumbar region, Right iliac region, Hypogastric region, Left iliac region
From superior to inferior, name the planes of the abdomen
Transpyloric, Subcostal, Supracristal, Intertubercular, Interspinous
What is found at the transpyloric plane?
Occurs at L1 level. Pylorus of Stomach Neck of Pancreas Fundus of Gallbladder Renal Hilum Duodenojejunal Flexure End of Spinal Cord (adult)
What is found at the subcostal and supracristal planes?
Subcostal Plane – L3
Origin of Inferior Mesenteric Artery
Supracristal Plane – L4
Bifurcation of the aorta
What organs are found in each of the abdominopelvic regions?
Right hypo: Gallbladder Epigastric: Stomach, Duodenum, Pancreas Left hypo: Pancreas Right lumbar: Kidney Umbilicus: Small bowel, caecum, retroperitoneal structures Left lumbar: Kidney Right iliac: Appendix + Caecum Hypogastric: Transverse colon, bladder, uterus and adnexae Left iliac: sigmoid colon
What constitues foregut, midgut and hindgut?
Foregut: Distal oesophagus to proximal half of 2nd part of duodenum
Midgut: Distal half of 2nd part of duodenum to proximal 2/3 of transverse colon
Hindgut: Distal 1/3 of transverse colon to rectum
Describe visceral vs parietal innervation
Visceral: Autonomic
Sympathetic – T1 – T12, L1,L2
Parasympathetic – CN III, VII, IX, X, S2 - 4
Parietal: Somatic
Describe site of pain and character in visceral vs parietal peritoneum
Visceral: Site of pain: Embryological origin Character: Dull, crampy, burning Parietal: Site of pain: Well-localised Character: Sharp ache
Describe innervation and site of pain for different parts of gut
Foregut Innervation: T5-T9 Site: Epigastrium Midgut Innervation: T10-T11 Site: Umbilical Hindgut Innervation: L1-L2 Site: Hypogastrium
What 2 categories do most painful conditions of the abdomen fall into?
1. Inflammation Constant pain (‘aching’) Made worse by movement Persists until inflammation subsides 2. Obstruction of a muscular tube: Colicky pain (‘gripping’) Fluctuates in severity Move to try and get comfortable
What is a third type of abdominal pain?
Prolonged obstruction of a hollow viscus causes distension. Constant stretching pain. Different from ache of inflammation & not colicky - may be due to ischaemia.
What type of pain is associated with the different organs?
Kidneys - colicky Liver - Constant Gallbladder - Colicky Spleen - Constant Intestinal - Colicky
Compare character of pain caused by ureteric colic, biliary colic and intestinal colic
Ureteric colic most intensely painful with greatest fluctuations in pain level. Waves of 3-10 minutes. Biliary colic remains at an almost constant intensity with shorter cycles. Intestinal colic least painful with lowest amplitude.
Where does upper zone pain radiate?
Gallbladder pain in right hypochondriac pain radiates through to the back and right. Stomach, duodenum and pancreas pain in epigastrium radiates straight through to the back. Pancreatic pain in the left hypochondriac region radiates through to the back and left.
