From Maine to Alaska surgeons line up to learn how to perform the most minimally invasive surgery available.Dr. Alex Rosemurgy: Yes, It's one incision as opposed to three or four or five.Melissa Medley: It's called laparoendoscopic single site surgery, or LESS. Doctors use it to remove gall bladders, appendixes, liver cysts, and repair hernias, and acid reflux disease. A specially-designed port that's inserted through a one-centimeter cut at the belly button allows miniature tools to enter the body..Dr. Alex Rosemurgy: We could argue that there's less pain, and we can certainly say that with one incision there's less risk of problems with hernias and infections.Melissa Medley: Sunny Lichtenberg needed surgery for a swallowing disorder.Sunny Lichtenberg: "I had really gotten to the point where I couldn't eat at all.Melissa Medley: An operation that used to require up to five incisions across the stomach now only needs one at the belly button.

"I think it made my recovery time so much less." Melissa Medley: Today, the piercing above her belly button is actually bigger than the scar from the operation.Sunny Lichtenberg: One incision is absolutely wonderful, I was able to go back to work in a weekMelissa Medley: Surgery that does more with less and allows patients to get back to their lives sooner.
