Translational Research is the research to apply and mediate a fundamental research result to the clinical field effectively. The integration of the diagnosis and the treatment is an important item in the life science field from the viewpoint of quality of therapy and minimally invasive therapy. ⋯ A high function operating robot (manipulator) as an endoscopic robot and image-guided minimally invasive device are important in the point of view of the development of a medical device shown with a medical device industry vision. We describe an outline of our ongoing development of endoscope system, intraoperative MRI (intelligent operating theater) and robot surgery system in neurosurgical field.

Laparoscopic radiofrequency ablation (RFA) is a safe and effective method for tumor destruction in patients with unresectable liver tumors. However, accurate probe placement using laparoscopic ultrasound guidance is required to achieve complete tumor ablation. After evaluation of an ultrasound navigation system for transcutaneous and open RFA, we now intend to transfer this technique to laparoscopic liver surgery. This study aimed to evaluate an electromagnetic navigation system for laparoscopic interventions using a perfusable ex vivo artificial tumor model. ⋯ Laparoscopic RFA requires advanced laparoscopic ultrasound skills for accurate placement of the RFA probe. The use of an ultrasound-based, laparoscopic online navigation system offers the possibility of out-of-plane needle placement and could increase the safety and accuracy of punctures. The perfused artificial tumor model presented a realistic model for the evaluation of this new technique.

Randomized Controlled Trial Comparative StudyEffectiveness of computer-navigated minimally invasive total hip surgery compared to conventional total hip arthroplasty: design of a randomized controlled trial.
Moderate to severe osteoarthrosis is the most common indication for Total Hip Arthroplasty (THA). Minimally Invasive Total Hip Surgery (MIS) and computer-navigated surgery were introduced several years ago. However, the literature lacks well-designed studies that provide evidence of superiority of computer-navigated MIS over a conventional THA technique. Hence, the purpose of this study is to compare (cost)effectiveness of computer-navigated MIS with a conventional technique for THA. It is our hypothesis that computer-navigated MIS will lead to a quicker recovery during the early postoperative period (3 months), and to an outcome at least as good 6 months postoperatively. We also hypothesize that computer-navigated MIS leads to fewer perioperative complications and better prosthesis positioning. Furthermore, cost advantages of computer-navigated MIS over conventional THA technique are expected. ⋯ Based on studies performed so far, few objective data quantifying the risks and benefits of computer-navigated MIS are available. Therefore, this study has been designed to compare (cost) effectiveness of computer-navigated MIS with a conventional technique for THA. The results of this trial will be presented as soon as they become available.

Multicenter Study
A cohort study of acute plastic surgery trauma and burn referrals using telemedicine.
A store-and-forward telemedicine system was used to supplement normal telephone referrals to the plastic surgery unit at the Queen Victoria Hospital (QVH). During a 12-week prospective study, 11 units (8 hospitals and 3 minor injury units) with the telemedicine system and 10 units (8 hospitals and 2 minor injury units) without it regularly made referrals (at least 10) to the QVH. There were 389 referrals from the telemedicine-equipped units and 607 telephone referrals from the non-telemedicine units. ⋯ There was a significant difference in the management of patients when the telemedicine system was available, with more patients booked directly into day surgery and fewer attending for assessment. The burns unit and the day surgery unit demonstrated a significantly improved accuracy of triage. Telemedicine could have a valuable role to play in the triage and planning of acute plastic surgery referrals.

Robotic technology is nothing more than an enhancement along the continuum of laparoscopic technological advances and represents only the beginning of numerous more forthcoming advances. It constitutes a major improvement in the efficiency, accuracy, ease, and comfort associated with the performance of laparoscopic operations. ⋯ In our hands, robotic operative times for simple and radical hysterectomy are shorter than those obtained by conventional laparoscopy. Robotic technology is preferable to conventional laparoscopic instrumentation for the surgical treatment of gynecologic malignancies and most operations for benign disease of certain complexity such as hysterectomy myomectomy, and invasive pelvic endometriosis.
