Study Details

Study Description

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
  • Device: Surgisis Gold Graft
  • Procedure: Control
N/A

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.
