Some issues Dr. Catherine M. McManus, MS, MD can help you with:

Adrenalectomy (Adrenal Surgery)

Adrenalectomy is a surgical procedure to remove the adrenal glands, which lie above each kidney. The adrenal glands are responsible for producing hormones that are necessary for bodily functions, such as the regulation of blood pressure and metabolism. If the adrenal glands overproduce certain hormones, or if a tumor grows on them, removal of the glands is a treatment option.

Adrenal surgery can be open or laparoscopic. Laparoscopic adrenalectomy is a minimally invasive procedure that inserts a thin tube with a camera (laparoscope) through several small incisions on the abdomen. The surgeon uses the laparoscope to guide the procedure and is able to access and remove adrenal glands through the small incisions. Laparoscopic adrenal surgery lasts approximately 1-2 hours.

Laparoscopic adrenalectomy is associated with shorter recovery periods, reduced risk of infection, and smaller scars. Although these factors may be desirable, the location of the tumor, its size, and the severity of the condition may require that an individual instead undergo open surgery. An open adrenalectomy is typically done for larger adrenal tumors and requires a single, large incision on the abdomen. Open adrenal surgery takes around 2-4 hours.

Following the operation, patients will remain in the hospital for 1-2 days for a laparoscopic adrenalectomy or 3-5 days for an open adrenalectomy. Patients will likely have a liquid diet immediately after their surgery, but should be able to return to solid foods after a day. If both of the glands are removed, patients will be given drug therapy to replace the hormones they produced.

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.
