title: Novel technologies for natural orifice surgery: an overview.
abstract: Natural Orifice Surgery (NOS) is now being elaborated with the aim to make abdominal surgery simpler and safer. The existing natural openings of the body are used for introduction of surgical instruments and thus to perform surgical procedures while avoiding to penetrate the abdominal wall. Actually, the transvaginal and transgastric approaches are the common routes used for NOS applications in humans. The transvaginal approach does not necessitate any sophisticated devices for opening and closure of the posterior colpotomy, thus being easy for the surgeon and safe for the patient. In contrast, the problem of transluminal access and closure represents significant obstacles in the transgastric approach and is still unsolved. In order to achieve this goal, various surgical prototype devices have been developed. This article aims to give an overview on the current status of techniques and technologies that are being developed and applied in conjunction with NOS procedures.
