If laser surgery is done on the cervix, the clinical sequelae are as follows: 1. If not well mastered, laser surgery may damage the mucosa of the cervical opening, causing adhesions or narrowing of the cervix, which may clinically cause dysmenorrhea. If adhesions of the cervix occur, it may also clinically lead to acute lower abdominal pain when menstruation occurs, which requires cervical dilatation to give treatment; 2. If laser surgery is done, if the local tissue of the cervix is destroyed at that time in a more serious situation, it may lead to slight changes in the local anatomy of the cervix. This will reduce the local secretion of the cervix, mainly destroying the glandular ducts of the cervix, so this is the sequelae of laser surgery done on the cervix.
