Hello, we do minimally invasive surgery. The navel is an incision, because this part is hidden. When we do laparoscopy, we choose incision, so we can't see the back.

Suggestion:

Such an incision may have scar hyperplasia or inflammatory hyperplasia, and may have a lump; If it's not too painful, it's fine. After a long time, it may gradually improve; Combined with local doctors, you can't see it after all.
