Minimally Invasive Surgery: How It Works

Posted on April 21, 2019 by Henry Ford Health Staff

Surgery has come a long way since the days when a routine trip to the operating room would require a long, painful incision and many days recovering in the hospital. Modern minimally invasive surgery uses unique small tools that allow surgeons to safely perform these same procedures through small openings.

These minimally invasive surgeries may result in less bleeding, reduced risk of infection and other complications, shorter hospital stays (or even going home the same day), faster recoveries and less scarring.

“As a general surgeon, I choose from a variety of surgical techniques, ranging from traditional open surgery to less invasive options, based on what will best take care of the needs of each patient,” said Henry Ford Allegiance Health general surgeon Shawn Obi. DO, FACS. “I use minimally invasive surgical options whenever it is appropriate because it typically causes less discomfort for the patient, lets them return to work sooner, results in lower risks of complications, and gets patients back to more normal function sooner than with open surgery.”

When performing minimally invasive surgery, instead of making a large incision, the surgeon typically makes three to five small incisions and then inserts narrow tubes called trocars. A lighted, miniature camera is then placed through one of the trocars. The images from the camera are displayed on large video monitors that give the surgeon a clear, magnified view. The surgeon then places specialized instruments through the other trocars to perform the necessary procedure.

Minimally invasive surgical techniques include robot-assisted surgery and laparoscopic surgery for procedures in the abdomen and in the chest, single incision surgeries in which the instruments and camera go through a single incision at the belly button, and incisionless endoscopic procedures using a flexible scope placed through the mouth and into the stomach, intestines or airway.

If you’re having you surgery in the near future, talk with your surgeon to learn if a minimally invasive option is appropriate for you.
