Natural orifice surgery: new concept in minimally invasive surgery

We present the concept of natural orifice surgery and of scarless operations, with their access routes, their multidisciplinary character, and challenges to their development. We point out the intra- and postoperative advantages. We emphasize the use of the vaginal route and posterior colpotomy in the application of natural orifice surgery in vaginal hysterectomies and surgical access to adnexa, which includes tubal ligation. We highlight the need for mastering these surgical modalities, which can bring great advantages to patients in Brazil.
