Hernias Flashcards
what is the definition of a hernia
protrusion of an organ through a wall which normally contains it
where does a spigellian hernia occur
semilunar line (lateral border of rectus abdominus at the arcuate line)
what does an epigastric hernia occur secondary to
raised chronic intrabdominal pressure (pregnancy, ascites, obesity)
what do paraumbilical hernias normally contain
just fat (they do not strangulate)
what’s the difference between a sliding and a rolling hiatus hernia
sliding is where the stomach slides up through the diaphragm and a rolling is where a separate part of the stomach folds and enters through the diaphragm
Ix for hiatus hernia
barium swallow or OGD
where is the deep ring found in the inguinal canal
at the midpoint of the inguinal ligament (made of transversalis fascia)
borders of hesselbachs triangle
inferior epigastric vessels, border of rectus abdominus, inguinal leg
how do direct/indiredct hernias present in relation to the inferior epigastric vessels
direct are medial and indirect are lateral
how do indirect inguinal hernias occur
failure of the processes vaginalis to close
if hernia is strangulated, what Ix do you do
CT
what is the most common type of surgical repair for inguinal hernia (only do surgery if symptomatic or if strangulated)
open mesh repair
why is a femoral hernia more likely to strangulate
rigidity of its borders
how are femoral hernias treated
ALWAYS surgically
what is the femoral canal
empty space next to femoral vein containing fat and lymphatics. It is a space which allows expansion of the femoral vein
