Adrenal Abnormalities

These are only general guidelines and not meant to replace instructions from a physician. Please talk with your physician about your specific condition.

Please ask your physician about any additional steps you should take before your surgery.


Our surgeons perform open surgery, as well as minimally invasive surgeries, for adrenal abnormalities. The decision to perform a specific type of operation is often dictated by the anatomic and size characteristics of your particular tumor, as well as your past history of operations and health. Your surgeon will explain your particular procedure in more detail at your consultation.

Minimally invasive surgery. Minimally invasive surgery is performed with laparoscopy or robot-assisted surgery using the da Vinci Surgical System.

Open surgery. Minimally With open surgery, your physician will make an incision at the site of the abnormality large enough so he or she can see and touch your internal organs while operating.
