Is scar tissue from a gallbladder removal via laparoscopy dangerous at all? should i leave it like this?

Adhesions,: This scar tissue to which you refer, called "adhesions", will always occur after surgery - part of the post-operative healing process. At times, they can cause obstruction of the intestines which may require hospitalization or even more surgical management, but there's nothing we can do preemptively to not make that happen. Thankfully this is not the norm.
