Using stitches to bind skin together seems so primitive. Why not use a special slug glue that sticks to skin? Biologists working on that medical technology now think they could make surgical sutures and staples relics from the past.

A number of scientists are currently studying the different kinds of natural adhesives produced by mussels, snails, worms, insects and other living things. Ithaca College biology professor Andrew Smith and his students are carefully collecting slug secretions in an effort to create an effective adhesive derived from it.
Slugs secrete special gels that help them move across a surface. "Gel like this would make an ideal medical adhesive," Smith told the college. "It would stick to wet surfaces and no matter how much the tissue flexed and bent, the gel would flex and bend with it. There would be no leakage or scarring."
Surgical staples and sutures are the norm because they can keep bodily fluids put, but these measures can also fail by popping or coming undone. Gluing skin together sounds like it would work better, but the right adhesive needs to stick to wet surfaces and also hold fluids back effectively.
