lecture 1 groin Flashcards
inguinal region
junction between anterior abdominal wall and thigh; area between ASIS and pubic tubercle
anterior abdominal wall
weakened in this region
clinical importance - popular question to describe walls of canal
potential site for most abdominal hernias (4 walls of femoral (lymphatics) and inquinal canal): male (testes outside) > female (ovaries inside)
anatomical importance
structures exit and enter abdominal cavity; femoral sheath covers femoral artery and vein and canal (canal not part of artery and sheath), nerve outside of sheath
inguinal canal
testis and spermatic cord descend from abdomen into scrotum via developing inguinal canal; in female uterine round ligament descends through developing inguinal canal
femoral canal
below inguinal ligament through which femoral artery and vein pass; medial compartment of femoral sheath (lymphatics through); artery and vein lateral to canal
define hernia
condition which part/whole of organ or tissue abnormally protrude through wall of structure containing organ/tissue
anatomy of hernia
abdominal sac, neck of hernia between abdominal wall with defect, hernia coverings (skin) so appears large lump, intestinal loop contains contents of hernial sac (e.g. bowel, bladder)
clinical signs and symptoms of hernia
lump/protrusion from groin, intermittently/persistently, painless/painful and uncomfortable, may be reducible or irreducible, may be strangulated with tissue death - associated with vomiting, constipation and intestinal obstruction - emergency to remove section of gut as will never recover
