[NOTES. History and current situation of natural orifice transluminal endoscopic surgery in Spain].

Natural orifice transluminal endoscopic surgery (NOTES), involves a group of new endoscopic approaches to the abdominal cavity, with potential advantages over conventional laparoscopic surgery. It is based on the possibility of performing intra-peritoneal surgical techniques through natural orifices by entering the peritoneal cavity through natural orifices perforating the organ that allows direct access to that cavity (stomach, vagina, rectum, bladder). The possibility of using this same route to access the retroperitoneum and mediastinum has subsequently been postulated.
