Comparative Prospective Data Collection in Connection With Two Different Treatment Methods: Robotic Assisted Laparoscopy and Conventional Laparoscopy

Study Overview
=================
Brief Summary
-----------------
This is a prospective, randomized, single-center, observational clinical trial at the Department of Women's Health of the University Clinic Tübingen. Four hundred patients affected by uterine diseases that undergo treatment with robotic assisted laparoscopic procedures using the Da Vinci Robotic Surgical System (200 patients) or conventional laparoscopic surgery (200 patients) will be recruited. In addition retrospective data of 200 patients that underwent conventional laparoscopic surgery in the past will be documented. At the end of patient recruitment, surgical procedure times, the technical limits encountered, estimated blood loss, intra- and post-operative complications and the percentage of conversions from the robotic assisted treatment /conventional laparoscopic surgery to multiple access and/or to a laparotomic (open) approach will be documented.
