Telementoring.
Telementoring began in the 1950s and is an advanced application of telemedicine that involves the removed guidance of a procedure where the student has no or limited experience. In the past 10 to 15 years, telemedicine has been revisited as a result of the healthcare delivery crisis, budgetary concerns, and the impact of managed care. In recent years, telementoring has had a number of successes which have led to further recent telementoring investigations and developments. Telementoring programs were established because it was impractical for specialized minimally invasive surgeons to proctor fellow surgeons during the adoption phase of new techniques. This catalyzed the establishment of formal telementoring procedural guidelines and networks. Efforts have been made in the remote direction of laparoscopic spermatic vein ligations, renal biopsy, nephrectomy, varicocelectomy, fetoscopy, and ophthalmology. Pilot studies in 2000 have statistically validated that telementoring can be as effective as on-site mentoring. In order to successfully conduct telementoring missions, however, it is important to follow a precise algorithm. If a standardized protocol is followed, it will ensure that telementoring is practiced safely and efficiently.

Wireless virtual instrument measurement of surgeons' physical and mental workloads for robotic versus manual minimally invasive surgery.
The human-technology interface in traditional minimally invasive surgery (MIS) is difficult for the surgeon. Efforts to improve this interface include the use of robotic surgery systems. Ergonomics studies are required to help understand and improve the MIS user interface. We have developed a tetherless virtual instrument (VI) ergonomics workstation for measuring the physical workloads and stress levels of surgeons performing MIS. The workstation records physiological measures of workload and stress and audio and multiple channels of video. The workstation frees up the subject so that studies can be performed in complex and realistic settings, including the operating room. We illustrate the use of the tetherless ergonomics workstation in a study to compare performance and workload for manual and robotically-assisted MIS. The surgeon volunteers were experienced with manual MIS but had no previous experience with the robotic system. The study results showed that the robotic system reduced the workload and stress levels for these subjects but somewhat degraded their performance. Additional studies are needed to determine the relative effects on performance of user inexperience and the robotic interface.

The Impact of Technology on the Resolution of Minimally Invasive Training and Credentialing Challenges of the 21st Century.
After the meteoric entry of minimally invasive surgery onto the general surgery scene 9 years ago, it currently stands at a crossroads with regard to the 21st century. Many challenges hamper safe and costeffective deployment of minimally invasive techniques. There must be a stabilization and reduction of complication rates associated with laparoscopic cholecystectomy. Common bile duct injuries are in fact two to three times higher for laparoscopic cholecystectomy than for the open procedure. This matter has been discussed only at local morbidity and mortality conferences or at national meetings. Patients are being injured. The surgical community has failed to police itself and the public knows it. This led in 1992 to New York State health officials setting standards of training and surgeon preparedness for performing laparoscopic cholecystectomy. If surgeons don't handle the problem, the politicians and the lawyers soon will.
