Some issues Dr. Martin R. Weiser, MD can help you with:

Laparoscopic Surgery

Laparoscopic surgery is a kind of minimally invasive surgery using a thin, narrow tube called a laparoscope. Usually performed on the abdomen or the pelvic region, the surgeon makes a few very small incisions instead of one large one.

During the procedure, the surgeon inserts the laparoscope, which contains a light and camera that allows the surgeon to see what is happening inside the body. Then tiny tools are placed through the small openings and used to perform the surgery.

The most common laparoscopic surgery is gallbladder removal, but laparoscopic surgery may also be used for the removal of a kidney or appendix, to treat certain cysts and tumors, for bariatric surgery, for some GERD treatments, or for hernia repairs, among others.

Because laparoscopic surgery only uses a few tiny incisions, the scars are minimal and recovery is easier than with open surgery.

Robotic Surgery

Robotic surgery is a type of minimally invasive surgery, using a tiny opening to get inside the body instead of making a large cut. It uses small tools attached to a thin robotic arm, which is controlled by the surgeon. Robotic surgery may be referred to by the specific kind of robot that is used. The most advanced robot currently in use is called the da Vinci, and surgery using it is sometimes called da Vinci surgery.

There are many benefits to robotic surgery, both for the patient and the surgeon. Robotic surgery allows for more precise movements and increased control during very delicate surgical procedures. This makes performing surgery accurately much easier for surgeons and reduces fatigue. The smaller 'hand' of the robot can enter the body via a much smaller opening, which reduces the risk of infection and scarring and leads to a faster recovery. The robotic hands also contain tiny moveable cameras among their tools, giving surgeons a much closer view of the procedure than would be possible with traditional surgery.
