Hernias Flashcards
opening or weakness in the abdominal muscular layers
hernia
what are the three different hernias
- external (abdominal wall)
- internal
- diaphragmatic
visceral contents are pushed out of the muscular layers (can feel and see it)
external hernia
viscera protrudes through the mesentery or peritoneum into a COMPARTMENT inside the abdomen
internal herina(need imaging)
abdominal contents protrude into the thoracic cavity
diaphragmatic hernia
what are the 4 external hernias
- umbilical/epigastric
- spigelian
- incisional
- inguinal
protrusions though the umbilicus that have an acquired origin as a consequence of increases in pressure from PREGNANCY OR ASCITES
adult umbilical hernia (2% cirrhotic patients/obese)
hernias that occur through the linea alba at the region from the xiphoid process down to the umbilicus
epigastric hernia
rare form of abdominal wall hernia that occurs through a defect in the LINEA SEMILUNARIS
spigelian hernia
iatrogenic hernia occurring 2-10% of all abominal operations secondary to breakdown of the fascial closure prior to surgery
incisional hernia
hernia that occurs just lateral to the rectus abdominis
spigelian hernia
75% of all hernias, 25x more common in males than females
direct or indirect hernia (inguinal hernia)
hernia that extends into the scrotum and lateral occurs lateral to the lateral umbilical fold
indirect hernia
hernia that RARELY GETS INTO SCROTUM, occurs medial to the lateral umbilical fold
direct hernia
hernia travels below the inguinal ligament through the femoral canal
femoral hernia
