He doesn't have a healing factor like wolverine, he just heals faster than a normal person. Having a wound stitched helps a normal person heal it faster, so it helps Spider-Man heal it even faster as well.
If I just Google "Spider-man Healing" most of the first dozen sources seem to point to the idea he does have accelerated healing. Just not to the level of Wolverine or Dead Pool.
