A construct for use in an abdominal surgery is described. The construct contains an allograft having at least one layer of human amnion and chorion tissues, and has a size and shape appropriate for covering an incision or a surgical site resulting from the surgery. Methods of preparing the construct and using it in an abdominal surgery are also described. The products and methods improve the performance of the abdominal surgery, e.g., by reducing adhesions, scar formation while also reducing inflammation and risk of post-operative infection.
