Only if it's a big long gaper .If you don't have stiches you can use a regular needle and thread I have had to do this in the past just make sure you alcohol the thread and needle pull the skin together and pretend you are sewing a pillow case shut one stitch at a time . Just put the needle through both skin sides and pull it together and make a knot , cut the thread and go about 1/4" over make another , and another until the wound is closed! this is all I know to tell you .
