Magnetic system could be key to surgery without scars

e been able to successfully remove a kidney using the Magnetic Anchoring and Guidance System.

While working on the system, Dr. Daniel Scott, assistant professor of surgery, joined UT Southwestern as director of the Southwestern Center for Minimally Invasive Surgery. He said the technology may solve the fundamental problem of guiding instruments through the abdomen for natural orifice surgery, which now inserts the instruments through the throat, colon or vagina.

“The current state of the art for laparoscopic surgery requires four or five holes. The question behind this is, can we do the surgery through only one hole and can we hide the hole in a cosmetically advantageous or less painful location,?Dr. Cadeddu said.

Study researchers concluded that “the ability to reduce the number of trocars (holes) necessary for laparoscopic surgery has the potential to revolutionize surgical practice,?but noted that there will be a learning curve for the new system and that because of the expanded maneuverability, surgeons will likely need to develop new techniques.

Also, until the system is fully tested in humans, surgeons won’t know whether fewer entry points will result in fewer complications or faster healing, advantages usually seen in moving from conventional surgery to laparoscopic surgery.
