Abdominal Hernia
repair principles
ensure viability of entrapped contents
return viable tissues to normal position
obliterate redundant hernia sac tissue
close hernia ring
consider...
midline laprotamy
muscular or facial flap for reconstruction
mesh implants if
clean
classification
opening
true
contents are enclosed in peritoneal sac
false
contents are outside of normal abdominal opening
incisional hernias
huge contamination concern
can occur up to 7d post-op
complete abdominal exploration required
copious lavage
traumatic
low incidence

vaginal process
large
uncommon
indirect
abdominal viscera enter vaginal process
prepubic
umbilical
migration of folds on abdo wall
cephalic
caudal
lateral
umbilical aperture remains after fusion
surgical repair
not necessary if <2mm hernial ring
immediate surgery if intestines size
close later/electivel if very large
omphaloceles
herniated contents covered by amniotic tissue
euthanize
