This time, natural adhesion -> I think I will re-operate with a partial incision, but
 they said that it is not a complete incision and
 that they may not be able to remove all the threads.
 
I had it done about 11 years ago when I was in middle school, so the hospital is as good as gone and I don't know the doctor's name and I don't know if it is a single knot or multiple knots. ㅠ
 
Is there any practice in which reoperation from burial to partial incision or burial was performed without removing the existing threads?
