Primary Outcome Measures:
  • 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.


Enrollment: 402
Study Start Date: August 2005
Study Completion Date: September 2012
Primary Completion Date: September 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
Surgisis Gold Graft
Device: Surgisis Gold Graft
Surgisis Gold Graft is placed as an underlay following open bariatric surgery.
Active Comparator: 2
Control
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 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.
