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:

• 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

• 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.

Laparoscopic adhesiolysis and recurrent

hernia mesh repair results in:• Low rate of adverse events

• Improved health-related quality of life

• A risk of recurrence similar to that of first time hernia repair


ConclusionsConclusions

In experienced hands, laparoscopic

repair of ventral hernias has:

• low recurrence rate

• low incidence of complications

• short hospital stay
