Inguinal hernias
90% men, 10% women
What are the abdominal wall layers in the inguinal canal? (4)
Peritoneum + fat
Transversalis fascia
Transversus abdominis
Internal/external oblique
Which muscle is not found in the inguinal canal?
transversus abdominus
What are the vessels within the inguinal canal? (3)
Testicular artery
Cremasteric artery
Artery to the vas deferens
What are the nerves that run within the inguinal canal? Alongside it?
Genital branch of the genitofemoral nerve
Ilioinguinal nerve runs alongside
What are the 3 fascial layers that run through the inguinal canal?
External spermatic
Cremasteric
Internal spermatic
What are direct inguinal hernias?
Passing through Hesselbach’s triangle
What are the sides of Hesselbach’s triangle?
Rectus abdominus
Inguinal ligament
Inferior epigastric artery
What are femoral hernias?
Pass through the femoral space, with the inguinal ligament above, cooper’s ligament below
Where are the femoral vessels relative to a femoral hernia?
Laterally (VAN)
What is the ligament below femoral hernias? Above?
Below = Cooper's Above = inguinal
What is the Bassini repair?
Single layer reconstruction of the inguinal floor
What is the Shouldice repair?
Four-layer reconstruction of the inguinal floor
What is the McVay repair? What is significant about this method of repair?
Inguinal floor brought to cooper’s ligament
Closes the femoral space
True or false: all tissue repairs are without prosthetic reinforcement
True
Why would you perform a tissue repair, without mesh?
Infection risk
Cheaper if without
What is a Lichtenstein Mesh repair?
Mesh reconstruction of the inguinal floor
What is the standard for hernia repair?
Lichtenstein mesh repair
Mesh reconstruction of the inguinal floor = ?
Lichtenstein Mesh repair
What is a pre-peritoneal mesh repair?
Placing mesh beneath the fascia to allow for pressure of abdominal contents to better hold the mesh
What are the benefits of a pre-peritoneal mesh repair?
Mechanically more sound
Eliminates the need to reconstruct the internal ring
What is a transabdominal preperitoneal laparoscopic inguinal hernia repair (TAP)?
Lap + incision into peritoneum + placement of mesh
What is a total extraperitoneal preperitoneal lap inguinal hernia repair? (TEP)
Entry into rectus sheath, and dissection of preperitoneal space (no entry into the peritoneum)
