6 Hernias Occur Throughout the Abdomen 1 Funk LM, Perry KA, Narula VK, Mikami DJ, Melvin WS. Current national practice patterns for inpatient management of ventral abdominal wall hernia in the United Sta te s. Surg Endosc . 2013;27(11):4104 - 4112. What is a hernia? ◦ Occurs when an internal part of the body pushes through a weakness (that is natural occurring or from a previous surgical incision) or hole in the muscle or surrounding tissue ◦ Likelihood of developing a hernia increases with age & obesity Treating a hernia ◦ Standard of care: Surgical repair of a hernia with a reinforcing material (mesh) ◦ ~90% of hernia patients receive a mesh repair 1 ◦ Mesh intended to reinforce the defect and provide long - term support Hiatal Hernia Diaphragm Epigastric Hernia Incisional Hernia Umbilical Hernia Inguinal Hernia

7 Ventral Hernia Patients Range in Complexity • CDC Wound Class I (clean) • Healthier patients - no co - morbidities • Primary hernia repair • CDC Wound Class II (clean - contaminated) • Patient co - morbidities (i.e., obesity, diabetes, COPD) • May have prior hernia repair failure • CDC Wound Class III (contaminated) & IV (infected) • Large defects • Infected synthetic mesh removals • Multiple prior hernia repair failures COMPLEX MODERATE SIMPLE Ventral Hernia Complexity Objective: provide patients the best repair the first time to prevent the simple patient from becoming the complex
