Outcome Measures
Primary Outcomes (1)
Hernia Recurrence Rate
Investigator confirmed hernia recurrence by physical examination
at about 24 months
Secondary Outcomes (1)
Early and Long-term Complication Rates
after surgery (day 1) to 24 months
Study Arms (1)
GORE® BIO-A® Tissue Reinforcement
Single-staged open complex ventral incisional repair of primary or recurrent anterior abdominal wall hernia.
Interventions
Retrorectus or intraperitoneal placement of device to reinforce the midline fascial closure after single-staged open complex ventral incisional hernia repair of primary or recurrent anterior abdominal wall hernia.
Eligibility Criteria
general and teaching hospitals
You may qualify if:
- Subjects will be informed about the study, and will have read; understood and signed the informed consent and authorization to use their PHI, as applicable
- Subjects willing and able to submit to postoperative follow-up evaluations including quality of life assessments up to 24 months after surgery
- Subjects of either gender that are at least the age of 18 years
- Subjects will have a Body-Mass Index (BMI) of \< 40
- Subjects will be undergoing single-staged open complex ventral incisional hernia repair with the retrorectus or intraperitoneal placement technique of the GORE® BIO-A® Tissue Reinforcement
- Subjects in which intraoperatively their surgical field/wound is characterized either a Type 2 or Type 3 in Table 1 in Section 12.0
- Subjects with a hernia defect \> 9 cm2 large when measured intraoperatively
- Subjects in which the required mobility for midline fascial closure without excessive tension to reapproximate the rectus abdominis muscle intraoperatively can be achieved
- Subjects in which one unit of GORE® BIO-A® Tissue Reinforcement will adequately reinforce the midline fascial closure with at least 4 cm of overlap laterally
You may not qualify if:
- Subjects who, in the surgeon's opinion, would have a difficult time comprehending or complying with the requirements of the study
- Subjects with a BMI \> 40
- Subjects with evidence of pre-existing systemic infections
- Subjects with cirrhosis or are currently being treated with dialysis
- Subjects with a wound-healing disorder
- Subjects with autoimmune disorder requiring \> 10mg of a corticosteroid per day
- Subjects who are immunocompromised such as, with HIV or transplant, or receiving chemo or radiation therapy
- Subjects with a hernia defect \< 9 cm2 large when measured intraoperatively
- Subjects with a hernia defect requiring more than one unit of GORE® BIO-A® Tissue Reinforcement
- Subjects in which intraoperatively there is an inability to achieve retrorectus or intraperitoneal placement of the device
- Subjects in which a midline fascial closure without excessive tension cannot be achieved
- Subjects in which intraoperatively their surgical field/wound is characterized either a Type 1 or Type 4 in the Table 1 in Section 12
- Subjects in need of concomitant surgical procedures other than indicated in the protocol as acceptable
- Subject in which their complex ventral incisional hernia repair requires more than one operation to reduce hernia and close fascia, including serial excision procedures - requiring subsequent surgery to complete their hernia repair
- Subjects with a hernia repair requiring an emergent procedure, such as strangulated bowel
