Brief Summary:
The primary objective is to compare the effectiveness of the Surgisis Gold Graft to suture closure alone in preventing an incisional hernia after open bariatric surgery.

Condition or disease Intervention/treatment Phase
Hernia Obesity Device: Surgisis Gold Graft Procedure: Control Not Applicable

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.

Arm Intervention/treatment
Experimental: 1
Surgisis Gold Graft
Device: Surgisis Gold Graft
Surgisis Gold Graft is placed as an underlay following open bariatric surgery.

Active Comparator: 2
Procedure: Control
Incision is closed without the placement of a graft material (standard of care control)

Primary Outcome Measures :
  1. Incisional Hernia [ Time Frame: 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.
