Repair of parastomal hernias with biologic grafts: a systematic review.

Background: Biologic grafts are increasingly used instead of synthetic mesh for parastomal hernia repair due to concerns of synthetic mesh-related complications. This systematic review was designed to evaluate the use of these collagen-based scaffolds for the repair of parastomal hernias.

Methods: Studies were retrieved after searching the electronic databases MEDLINE, EMBASE and Cochrane CENTRAL.
