Flashcards in EXAM #3: HERNIAS Deck (39)
What is the general school of thought for the surgical management of hernias?
Repair before they cause problems
What is the most common type of all hernias?
*Far more common in men*
Review the abdominal wall layers.
2) Subcutaneous tissue
- Camper's Fascia (fatty)
- Scarpa's Fascia (fibrous)
3) External Oblique
4) Internal Oblique
5) Transversus Abdominis m.
6) Transversalis fascia
Review the anatomy of the inguinal canal.
What is an indirect inguinal hernia?
- Hernia through the internal inguinal ring
- Lateral to the inferior epigastric vessels
- Within the spermatic cord
MD's Don't Lie
Where does a direct inguinal hernia pass through?
What is a direct inguinal hernia?
Hernia that occurs
- Adjacent to rectus abdominus
- Medial to inferior epigastirc vessels
- Superior to inguinal ligament
What patient's more commonly have femoral hernias?
What is a femoral hernia?
Hernia that passes into the femoral canal, below the inguinal ligament
How can an inguinal hernia be repaired with a "tissue repair?"
1) Bassini repair= single layer reconstruction of inguinal floor
2) Shouldice repair= four layer reconstruction of inginal floor
3) McVay repair= inguinal floor brought to Cooper's Ligament--closes the femoral space
What is the best tissue repair for an incarcerated femoral hernia?
McVay b.c is closes the femoral repair
Why perform a tissue repair?
1) No mesh available
What is the current standard hernia repair?
Lichtenstein Mesh Repair
What are the key characteristics of a Lichtenstein Mesh Repair?
1) Mesh reconstruction of inguinal floor
*Lowest risk of recurrence
What is the risk of a Lichtenstein Mesh Repair?
Prosthetic mesh infection
What is a Pre-Peritoneal Mesh Repair?
Mesh is placed INSIDE of fascia (vs. outside)
*Mesh is between peritoneum and transversus abdominus*
How do you place pre-peritoneal mesh?
Open or Laparoscopic
What are the benefits of Laparoscopic repair for pre-peritoneal mesh repair?
1) Less post-op pain
2) Less infection and hematoma
3) Quicker recovery with fewer work restrictions
What are the two approaches to the pre-peritoneal repair?
TAP and TEP
What is the TAP approach?
TransAbdominal Preperitoneal Laparoscopic Hernia Repair
What is the TEP approach?
Total Extraperitoneal Preperitoneal
How does the TEP differ from the TAP?
TAP= standard laprascopic approach
TEP= entry in RECTUS SHEATH
What are the evidence-based indications for laprascopic hernia repair?
1) Bilateral inguinal hernias
2) Comorbid umbilical
3) Young healthy individual that wants to return to work earlier
What is a Spigelian hernia?
Hernia along the semilunar line
What is the difference between an umbilical hernia in a kid and adult?
Kid= frequently regress (congenital)
Adult= acquired and progress/enlarge
How are umbilical hernias repaired?
1) Primary if 1-2cm
2) Mesh reinforcement for 2cm+ defects
What is an incisional hernia?
Failure of fascia healing
What are the risk factors for incisional hernias?
Early return to work
*Chronic hypoxia states
How long should people be lifting restricted to prevent an incisional hernia?
