[Novel laparoscopic techniques in gynecologic surgery].

The practice of gynecologic surgery has been revolutionized by laparoscopic techniques in the past decades. Nowadays minimal invasive procedures are feasible and safe standard options in the management of most benign and malignant gynecologic diseases. Natural orifices transluminal endoscopic surgery (NOTES) and laparoendoscopic single-site surgery (LESS) have been developed in an attempt to further reduce the morbidity and scarring with minimal invasive procedures. These techniques share a common conception that a reduction in the number of transcutaneous points of access may benefit patients in terms of port-related complications, risk of hernia formation, recovery time, pain and cosmetics by potentially performing scarless surgery. The development of LESS has been facilitated by the concept of scarless surgical procedures. Increasing experience revealed by recent publications have allowed for the expansion of NOTES and LESS techniques in the gynecologic surgery. Almost all laparoscopic procedures can be performed by acquiring these concepts. Although these surgical methods are feasible and safe, certain technical problems (e.g. loss of triangulation, problems of visualization, ergonomic considerations) has yet to be solved and several questions must be answered before LESS and NOTES could gain widespread acceptance as single procedures. Despite successful technical developments these methods remain investigational approaches and refinement of indications as well as further development of instrumentation are expected to define its area of future application.
