General Information:General Information:• 100,000 ventral hernia surgeries per year
• 3-20% of laparotomy incisions
• 10-15% of all hernia repairs
• 17% will develop incarceration or strangulation
• Mortality 0.3% • Elective repair, 1.1 %• Emergency repair
Primary repair of ventral hernia without mesh:Primary repair of ventral hernia without mesh:
• Recurrence rate 25%-45% after first repair
• 58% recurrence after second attempt

Primary repair of ventral hernia with mesh:Primary repair of ventral hernia with mesh:
10-20% recurrence
12 % infection rate and wound complications

• Components separation technique
resulted in 32% recurrence

Methods to decrease hernia occurrence and facilitate primary repair:
Methods to decrease hernia occurrence and facilitate primary repair:
• Large incision
• Extensive dissection
• Drains
• Mesh
• Co-morbidities
The increase in rate of wound complications in open incisional hernias repair is related to:

• wound complications
• recurrence rate
• LOS
• pain
• coverage of “Swiss cheese” abdomen
Preparing the patientPreparing the patient
• Consider bowel prep
• Pre-operative antibiotic prophylaxis
• Foley catheter
• Nasogastric tube
• SCDs/DVT prophylaxis
Preparing the patientPreparing the patient
• Tuck arms at side
• Secure patient to table
• Consider footboard
• Consider Ioban drape
EquipmentEquipment
Instrumentation
• Atraumatic graspers
• Ultrasonic shears
• 5 mm tacker
• Suture passer
• Identify approximate size of defect
• Determine sites for placement of ports
Sizing the meshSizing the mesh• What is the best way to measure the mesh?• 3 options: Intracorporeal with pneumoperitoneum,
extracorporeal with pneumoperitoneum, extracorporeal desufflated
• With extracorporeal measurement, the diameter of the outer (skin) circle is larger than the inner (peritoneal) circle.
• This difference is proportional to the size of the patient.
• Result is overestimation of hernia size and mesh by 1.7 to 3.1 cm

Access to abdomen• Blunt trocar with open technique
• Veress needle
• Remote from
hernia site
Trocar
Requirements depend on hernia size
• 11 mm or 12 mm
and 5 mm trocars
• Begin careful adhesiolysis
• Blunt and
sharp dissection
• Avoid use of
cautery
• Full extent of defect identified
• Beware of the presence of multiple defects
• Once the defect is measured a mesh is selected that provides at least 3 cm of overlap around the defect.
• Some surgeons use a 4 – 6 cm overlap.• This may be particularly important in
the recurrent hernia or in the morbidly obese patient.

• Ensure proper mesh surface
orientation
• Place anchoring sutures trans-abdominally
• Secure periphery of mesh with tacker
• Approximately 1cm apart
• The tensile strength of the transabdominal suture is 2.5 times greater than that of the tacker
• Cadaveric pig studies have shown that the optimal distance between fixation points is about 1.8 cm
• Or the ideal number of fixation points can be derived by the formula: (2pi r)/7) x 3 = 2.7r

What to do when an enterotomy occurs?What to do when an enterotomy occurs?
• Contamination repair injury and delay hernia repair
• No spillage repair hernia
• Bladder injury repair hernia
• Delayed bowel injury remove mesh and delay repair
What to do with seroma?What to do with seroma?
• Observation: most of them will resolve without intervention
• Repetitive sterile aspiration
• When persistent beyond 8 weeks or longer: removal of mesh and excision of hypertrophic mesothelium
Can seroma formation be decreased?Can seroma formation be decreased?
• 78 patients underwent 80 laparoscopic LVHR • Separated into 2 groups• Both groups repaired with ePTFE dual mesh secured by full-
thickness stitches and endoscopic tacks • Group A (n=28)
•subgroup A1; n=17 - overlap of 2.5 cm•subgroup A2; n=11 - overlap of 4 cm and a full-thickness suture
placed in the center of the hernia defect to reduce the "dead space." • Group B (n=52) Hernia sac cauterized by monopolar cautery or
Harmonic scalpel •subgroup B1; n=16 - overlap of 2.5 cm •subgroup B2; n=36 - overlap of 4 cm and a full-thickness suture

What to do for pain at transabdominal suture site?What to do for pain at transabdominal suture site?
• Nonsteroidal anti-inflammatory agents/oral narcotics
• Subfascial injection of combination lidocaine and bupivacaine
• 103 patients underwent LVHR• 24 patients (23%) had prolonged discomfort at a
transabdominal suture site• Treatment consisted of injection around the suture
site with 0.25 % bupivacaine with epinephrine and 1 % lidocaine
• 20 patients required a single injection• 2 patients required two injections • 2 patients failed local injection and were referred to an
anesthesia pain service • One underwent intercostal nerve block with resolution of
pain• The other is currently in treatment

Laparoscopic ventral hernia repair in the obese patientLaparoscopic ventral hernia repair in the obese patient
• LVHR in the morbidly obese population is safe and feasible, however, there is a higher, but acceptable recurrence rate.
• LVHR in morbidly obese minimizes the potential wound and mesh complications that frequently occur for open mesh repair in this group of patients.
