Robotic laparoendoscopic single-site surgery.

Laparoscopic surgery is frequently used in urology and the introduction of the da Vinci surgical system has served to further increase the demand for these procedures. Yet, laparoscopy is not without its drawbacks including port site complications, such as bleeding, hernia, internal organ damage and scarring. To further decrease morbidity of standard laparoscopy, newer techniques such as laparoendoscopic single-site surgery (LESS) are currently being investigated. LESS is technically challenging and reduces instrument triangulation and robust retraction, and is associated with a steep learning curve. To help overcome current limitations we have introduced the da Vinci surgical system to LESS and report our experience with robotic laparoendoscopic single-site surgery.
