New Surgical Skills

The pace of new technology in surgery is astounding.  Just yesterday learning open surgery skills took many years to perfect.  Now with minimally invasive surgery, there is a new skill set to learn and to master.  Tomorrow is here today, “Robotic Surgery” is even a more advanced skill set that will allow for greater dexterity and skill for the surgeon.  Patients benefit tremendously because with these advances, the ability for improved precision in surgery and better results is a significant benefit.

I remember training at Stanford in gynecologic surgery, it was a great enigma.  Sitting at the end of the operating table, holding a retractor as a resident.  I was the “third or fourth” surgical assist.  I could not really see anything, there were so many bodies huddled around the operating table.  I would begin to fall asleep because I had been up all night long on-call.  I thought, this is no way to learn.  I can’t see anything.  But since those days of sleepless nights and frustration, I came out a pretty great surgeon.  Learning minimally invasive techniques that have spared many patients from excess pain and disability.  Truly remarkable surgery, allowing patients to go home that day or the next.

I am in favor of the rapid progress of these new surgical technologies, and I am very excited that surgeons all over the world are sharing videos and techniques.  MDV1 is an agency for innovating physicians and surgeons consulting the BioDevice Space.  If you have any questions, please contact us phone: 408-309-8457

New Technology for Fibroid Ablation.

News from the Wall Street Journal on a novel new minimally invasive device  that treats fibroids in women.

Of all the pains and indignities the female body suffers, some of the most common are uterine fibroids—benign tissue growths in the womb. It’s estimated that as many as 70% of women develop them at some point. Most are asymptomatic and women never know they’re there. But in about one-third of cases—even more among African-American women—the fibroids become large enough to cause pain in the back, abdomen and pelvis, bloating and very heavy menstrual bleeding. Some grow to be as large as a grapefruit and can interfere with other organs.

The standard treatment is a hysterectomy, which permanently removes the uterus along with the fibroids. More than 200,000 hysterectomies are performed in the U.S. each year for fibroids; it’s the second most common surgical procedure for women, after Cesarean sections. read more
