The US Food and Drug Administration has approved TissuGlu, the first tissue adhesive available for internal use.

TissuGlu is a urethane-based adhesive that can now be used by surgeons to connect tissue flaps made during surgery to remove excess fat and skin or to restore weakened or separated abdominal muscles. 

Connecting the tissue flaps with an internal adhesive could reduce or eliminate the need for postoperative surgical draining of fluid between them, helping patients to return to their daily lives more quickly, the regulator said.

Approval was based on data from a study showing that 73% of participants who received TissuGlu required no postoperative interventions to drain fluid that had accumulated between abdominoplasty tissue flaps, and that those who did require intervention were more likely to need another operation to insert surgical drains.
