Detailed Description
This will be a prospective, randomized clinical trial comparing outcomes of use of a sublay of Surgisis Gold Graft for tissue reinforcement, as compared to suture closure alone in evaluating incidence of incisional hernias. Prior to undergoing open bariatric surgery, patients will be randomized to receive either Surgisis Gold Graft or suture closure alone. Subjects will be seen for follow-up visits at six weeks, three months, six months, one year and two years post-operatively. Patients may see their primary care physician for the one and two follow-up visits.

Outcome Measures
Primary Outcome Measures
- Incisional Hernia [2 years]
An obvious defect or interruption of the fascia in the area of the incision that was palpable on clinical examination and/or visible by a cross-sectional imaging modality.
