Primary Outcome Measures:
  • Incidence of incisional hernias [ Time Frame: 2 years ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: 1
Biodesign Graft
Device: Biodesign Graft
Biodesign 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)

Detailed Description:

This will be a prospective, randomized clinical trial comparing outcomes of use of a sublay of Biodesign 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 Biodesign 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.
