I also had my GB removed laproscopically. It took a long time for my belly button incision to heal as well. My surgeon said he had to make an extra-large incision just to get it out because my GB was so big. In fact, when I had the staples removed a week after the surgery, it was still open and bleeding. He told me to wash it with peroxide twice a day and then dry it with a sterile gauze pad and put some bacitracin and then use a butterfly bandage to pull it together from both sides. It took about three weeks, but it closed very nicely.
