Robot-assisted surgery is when a doctor guides small robotic arms through tiny incisions. It allows for greater range of motion than regular surgery.
Reasons for Procedure
This method may be used for surgery that:
The benefits of this type of surgery are:
Many adult and child surgeries can be done using this method. Some examples are:
Problems from robotic-assisted surgeries are rare, but all procedures have some risk. The doctor will go over some problems that could happen, such as:

Description of the Procedure
Several small incisions will be made at the surgery site. A needle may be used to inject gas into the area. This will make it easier to see inside the body. A scope with a small camera on the end will be passed through one of the incisions. The camera will display the area on a video screen. Next, robotic arms holding tools will be inserted through the holes.
While sitting nearby, the doctor will use lenses to look at a magnified 3-D image of the inside of the body. Another doctor will adjust the camera and tools. The robotic arms and tools will be guided by the surgeon. When the surgery is done, the tools will be removed. Stitches or staples will be used to close the incisions. Bandages will be used to cover them.
How Long Will It Take?
About 1 to 2 hours. It depends on the type of surgery.
Will It Hurt?
It depends on the surgery, but pain and swelling are common in the first 2 weeks. Medicine and home care can help.
