Title: Umbilical Hernias in the Foal


1
Umbilical Hernias in the Foal
  • By Pam Nolasco
  • AVS 466

2
Definitions
  • Hernia
  • Protrusion of an organ or tissue through an
    abnormal opening
  • Umbilical Hernia
  • Occurs when a piece of intestine protrudes down
    into a body wall defect in the umbilicus (naval
    area)

3
What Causes an Umbilical Hernia?
  • Congenital hernia present at birth and occurs
    during development of the fetus
  • Abdominal wall surrounding the umbilicus is one
    of the last areas of the body wall to close
  • If the body wall does not completely close, it
    will result in an umbilical hernia
  • Acquired hernia Not present at birth, occurs at
    3-4 weeks of age
  • Straining to defecate or micturate
  • Infection of umbilicus
  • Trauma at birth
  • Improper handling and/or management
  • Hereditary defect

4
Prevalence
  • Occurs in 0.5 to 2 percent of births
  • More common in fillies then colts

5
Types of Hernias
  • Hernias are oval in shape and one to several cm
    in diameter
  • Minor aka reducible hernia
  • Any bowel in the hernia that is still healthy can
    be pushed backed through the abdominal hole

6
Types of Hernias cont.
  • Severe Hernia
  • Intestine pushing through hole of the wall may
    strangulate
  • A section of intestine becomes trapped leading to
    loss of circulation to area, bleeding, infection,
    inflammation, necrosis, and/or death

7
Treatment
  • Majority of small hernias are self healing
  • Close spontaneously
  • It is common practice to wait for the foal to
    turn 6-12 months before turning to surgery

8
Treatment
  • Minor Hernias
  • Allow abdominal wall to close over and fix itself
  • Use daily reduction technique
  • Can be used for hernias 3-4 fingers in size
  • Use your fingers to push contents of hernia sack
    back into the abdomen on a daily bases
  • If hernia can no longer be reduced and isnt
    fixed, surgical correction should be considered

9
Treatment cont.
  • Larger hernia or un-reducible types
  • Surgery
  • Closed Technique repair hernia without opening
    abdominal cavity
  • Advantage simple
  • Disadvantage not seeing what is in the hernia
    sack.
  • Open Technique
  • More precise
  • Hernia sack can be opened, evaluated, fixed and
    repaired

10
Treatment cont.
  • Elastrator Ring
  • Closed surgery
  • Procedure
  • Give general anesthetic and roll foal on its back
  • Abdominal contents are pushed through the hole
    and rubber rings are used to hold skin tightly
    over hernia spot
  • This should keep contents from coming back out
    and allow abdominal cavity to close
  • Becoming a very common technique

11
Treatment cont.
  • Elastrator Ring
  • The ringed-off clump of skin, becomes deprived of
    blood, dies and rots, then falls off

Treatment with Elastrator Ring
  • Risk
  • Infection from site affects too much healthy
    skin, causing wound site to burst open
  • Infection can enter abdomen and cause serious
    problems

15
Key to Success
  • Early Assessment
  • Veterinarian Treatment
  • Take Action
