Suggest Signific Of A Laparoscopic Surgery

I went to 3 gynecologist. The doctor he is a Gynecologist/Oncology said that they will do a laparoscopy and if it is necessary will put the bladder and rectum in place. If I do start bleeding they will have to cut me? Also mentioned that it is a very big operation. The last gynecologist mentioned that it is a very big operation and that I must wait until I feel that I cannot go any further? What is the complications if I decide not to do it now? Is a safe with sex? I'm 59 years old.
