Key Simulated steps and operative Principles
1. The tough pig skin simulates tissue quality of fascia
Intraop step Simulated step
Creating fascia flap for hernia repair

Goals and Objectives
1. Describe how to perform a ventral hernia repair using the mesh underlay (sublay) technique
2. Use tension and counter tension to perform proper dissection for creation of fascia flap
3. Precisely suture mesh to fascia in a deep space without injuring abdominal contents
4. Demonstrate how to use abdominal instruments including Kochers, Ferris Smith forceps and retractors

Setup Step 1
Drill holes on the sides of a plastic box (ex: 9L Really Useful box, 6 1/16"H x 15 9/16"W x 10 1/16"D)

Setup Step 2
Insert four holes at the four corners of pork side

Setup Step 3
Excise 6 cm x 2 cm elliptical skin, the resulting defect will be the hernia defect

Setup Step 4
Suspend pork side skin side down using cable ties (recommend ≥ 12 inches) through the drilled holes on the side of the box

Setup Step 5
Clip and secure Bovie pad to the side of the pork side

Setup Step 6
Place an inflated balloon tube underneath the suspended pork side which represent intraabdominal contents

Procedure Step 1
Incise and divide the muscle

Checklist
Use proper technique and help with assistant to dissect through the muscle Dissect down to the free skin edge without
popping the balloon Create a skin flap circumferentially Securely suture the mesh with proper spacing Proper spacing to avoid folding or bunching
up of the mesh as well as bowel herniation
