I recently had surgery and they glued me together with "dermabond" which is just gorilla glue with a medical name so that it costs alot more. No sutures.
My niece, an orthopedic surgeon, told me to keep superglue in all of my first aid kits, especially the ones on my boat. No need to get the medically-branded version, which costs 10 times as much. She said that the risk of infection was a bit higher with glue off the shelf from the hardware store, but still low.
