Tele-Medicine --- Tele-Surgery

Tele-medicine is an emerging field in its infancy. It will have tremendous growth, changing our lives, due to its unique property that it not only allows “Expert Care” to be available to rural areas, but also to inner-cities when and where such “Expert” intervention is meaningful. Furthermore, with the introduction of Robotic Surgery and its growth during the past decade, Tele-Robotic Surgery would benefit from the same concept.

Power of Telecommunication

Combining benefits and power of Telecommunication with Medical services, brings about Tele-Medicine. While presence of the physician next to the patient can have its own healing merits, nevertheless it is impossible to have competent and expert medical practitioners to be present wherever their expertise is needed. Furthermore, as in the case of videoconferencing and web conferencing reducing costs by minimizing the need for travel, tele-medicine can also benefit the population that otherwise will not have access to the expert medical care. Today tele-diagnostics are a reality as they save costs, and provide immediate, round-a-clock service. For example, the MRI of an emergency room patient in New York at 11:00 p.m. is sent electronically to a competent radiologist oversees (where it is morning!) and results can be delivered within the hour. Another powerful example is by providing tele-care to prison inmates, where it would be challenging at best to either transport the prisoner to the medical facility or to bring the doctor to the prison environment.

There are numerous applications of tele-medicine. Here are a few:

  • Tele-dermatology
  • Tele-radiology
  • Tele-consultation
  • Tele-checkup
  • Tele-Surgery

Tele-Surgery

Tele-surgery is one of the more demanding fields of tele-medicine. In this case an expert surgeon will participate in a surgical case without being in the operating room. Even though the surgeon outside of the operating room could be the only surgeon performing the operation, as demonstrated on September 7, 2001 (See the video), the reality is that tele-surgery is a viable and valuable option where the less-experienced surgeons in the operating room and next to their patients will be assisted by the expert surgeon who could be hundreds of miles away as demonstrated on 2/28/2003 (See the video). This has lots of benefits: 1- Best outcome for the patient, 2- Local surgeon learns while being assisted/taught by the expert surgeon, 3- Reduced costs as no one travels. 4- Discomfort and expenses for patients and their family is reduced as they do not have to travel to the expert surgeon for the operation. These are the true values of tele-surgery that can be realized today and in the future.

Despite these advantages, there are challenges that need to be overcome:

  • Regulatory process in the U.S. to allow such delivery of care can be one of the main reasons preventing its adoption today (FDA allowed the one time operation on 9/7/2001. Canada's regulatory body is more forward looking and allowed the system to be used on a regular basis.
  • Current reimbursement process has no provisions to pay the expert surgeon outside of the operating room, performing the operation?

Technical information on Proof of concept 09/07/2001

The trans-atlantic operation was code-named Lindbergh in honor of the first trans-atlantic solo flight by Charles Lindbergh. Surgeon console was in NY and the patient and the robotic arms were in Strasbourg, France. The robot was Zeus® Tele-Susrgery system developed by Dr. Ghodoussi while at Computer Motion Inc. and France Telecom provided the highest quality, private ATM network. On that day Drs. Jacques Marescaux (the principal surgeon) and Dr. Michel Gagner operated from NY on the 68 year old French patient in Strassbourg, France.

Pertinent Data
The communications transport was a DS3 ATM Virtual Private Link set for 10 Mbps. Of this bandwidth, 7 Mbps was dedicated to the endoscopic video set at guaranteed delivery. Another 2 Mbps was provisioned for the video conferencing system showing the external view of the OR table (patient and robot positioning). Remaining bandwidth was set for the Zeus® robot data/control also set for guaranteed delivery. The transmission delay was 39 msec in each direction and the FORE systems' CODEC used 38 msec to encode and 38 msec to decode the endoscopic video in MPEG2 (DVD quality) format. For more information.

Technical information on Canada Tele-Surgeries which started on 02/28/2003

Due to the success of the Operation Lindbergh and success of the Zeus® system in Canada, health Canada approved the use of Zeus® Tele-Surgery within Canada for an extended study. The Surgeon console was in Hamilton, ON and the patient and the robotic arms were in North Bay, ON - 250 miles away. The robot was the sameZeus® Tele-Susrgery system developed by Dr. Ghodoussi's team at Computer Motion Inc. and Bell Canada provided the telecommunication link. Starting on Feb. 28, 2003 Dr. Mehran Anvari (the world-renown surgeon) operated from Hamilton, assisted and guided Dr. Craig McKinley in his operating room in North Bay, performing a Lap. Nissen Fundoplication procedure. Two such operations were performed back to back that day. Over 20 tele-surgery procedures (Nissen, Hernia, Bowel Resection …) were performed.

Pertinent Data
The communications transport was an MPLS public Link set for 7 Mbps. Of this bandwidth, 4 Mbp was dedicated to the endoscopic video set at Highest priority. Another 2 Mbps was provisioned for the video conferencing system showing the external view of the OR table (patient and robot positioning). Remaining bandwidth was set for the Zeus® robot data/control also set for Highest priority. The transmission delay was 15 msec RT and the CODEC used 120 msec to encode and decode the endoscopic video in MPEG2 (DVD quality) format. For more information.
