Adrenalectomy is a surgical procedure used to remove one or both adrenal glands. These glands, located on top of each kidney, are essential for hormone production that controls metabolism, blood pressure, immune response, and stress management. When an adrenal gland develops a tumor or functions abnormally, surgery may be required to restore hormonal balance.
Though adrenalectomy is not as commonly discussed as other surgical procedures, it plays a critical role in managing a range of endocrine disorders. Whether dealing with a benign adrenal tumor or a life-threatening adrenal carcinoma, understanding the procedure, its purpose, and what to expect can make a significant difference in the patient’s journey and outcome.
What Is an Adrenalectomy?
An adrenalectomy is the removal of one (unilateral) or both (bilateral) adrenal glands. The adrenal glands produce vital hormones such as cortisol, aldosterone, adrenaline, and noradrenaline. Tumors, overproduction of hormones, or suspected cancer can lead to the need for this surgery.
There are two primary types of adrenalectomy procedures: laparoscopic adrenalectomy, which is minimally invasive, and open adrenalectomy, which involves a larger incision. The choice of method depends on the size of the tumor, its location, the patient’s overall health, and whether the mass is benign or malignant.
Reasons for Undergoing Adrenalectomy
Adrenalectomy is recommended for several adrenal gland conditions, including
-
Adrenal tumors :- These may be benign (non-cancerous) or malignant (cancerous).
-
Hormone-secreting tumors :- Tumors that produce excess hormones, such as pheochromocytomas, cortisol-producing adenomas, or aldosterone-producing adenomas.
-
Adrenal cancer :- Although rare, adrenal cancer requires immediate surgical intervention.
-
Cushing’s syndrome :- Caused by cortisol overproduction.
-
Conn’s syndrome (primary hyperaldosteronism) :- Caused by excess aldosterone.
-
Adrenal metastasis :- Secondary cancer that has spread to the adrenal gland from other body parts.
Preoperative Evaluation and Preparation
Before undergoing adrenalectomy, patients typically go through a series of diagnostic tests and evaluations. These include blood tests, urine tests, CT scans, MRIs, and occasionally PET scans. These diagnostic tools help confirm the diagnosis, determine the nature of the adrenal mass, and assess the gland’s hormone production levels.
Endocrinologists, urologists, or oncologic surgeons usually collaborate to determine the most appropriate surgical approach. In some cases, patients may be prescribed medications to stabilize hormone levels before surgery, especially in hormone-secreting tumors.
Procedure of Adrenalectomy
The surgical procedure varies based on the chosen method laparoscopic or open surgery and the gland being removed. Here’s a closer look at both techniques
-
Laparoscopic Adrenalectomy :- This is the most commonly used method for removing small to medium-sized adrenal tumors. It is minimally invasive, requiring only a few small incisions in the abdomen or flank area. A laparoscope (a thin tube with a camera) and surgical instruments are inserted through these incisions to remove the adrenal gland.
This technique offers several benefits
-
Reduced postoperative pain
-
Shorter hospital stay
-
Faster recovery time
-
Minimal scarring
During the operation, carbon dioxide is used to inflate the abdomen, providing more room to operate. Once the adrenal gland is removed, the incisions are closed with sutures or surgical glue.
-
-
Open Adrenalectomy :- Open adrenalectomy is recommended for larger tumors, especially if there is a suspicion of cancer. This procedure involves a larger incision, typically on the abdomen, back, or side, depending on the tumor’s location.
Though it has a longer recovery time and more postoperative discomfort, open surgery allows the surgeon direct access to the adrenal gland and surrounding tissues. This method also enables complete tumor removal when there’s a risk of malignancy.
In both approaches, if only one adrenal gland is removed, the remaining gland typically compensates by increasing hormone production. In cases where both glands are removed, lifelong hormone replacement therapy is necessary.
Duration and Anesthesia
Adrenalectomy usually takes between 1 to 3 hours, depending on the complexity of the case and whether it’s done laparoscopically or via open surgery. The patient is under general anesthesia throughout the procedure, meaning they are unconscious and pain-free during the operation.
Recovery After Adrenalectomy
Recovery depends on the surgical approach. Patients undergoing laparoscopic adrenalectomy can often return home within 1–2 days and resume normal activities within two weeks. Open surgery, on the other hand, may require a hospital stay of 4–7 days and a recovery period of 4–6 weeks.
Some common post-operative experiences include
-
Mild pain or discomfort at the incision site
-
Fatigue during the first week
-
Hormonal fluctuations, particularly if the tumor was hormone secreting
Doctors monitor blood pressure, hormone levels, and electrolyte balance post surgery. In certain cases, steroid medications may be prescribed temporarily until the body adjusts to the new hormonal levels.
Risks and Complications
Like any surgical procedure, adrenalectomy comes with potential risks. Although rare, complications may include
-
Infection at the incision site
-
Bleeding
-
Blood clots
-
Damage to nearby organs or tissues
-
Hormone imbalances
-
Adrenal insufficiency (especially when both glands are removed)
To minimize risks, patients should disclose their full medical history, follow preoperative instructions carefully, and attend all follow up appointments.
Life After Adrenalectomy
For most patients, adrenalectomy significantly improves quality of life especially those suffering from hormone secreting tumors. Blood pressure and hormone levels often stabilize post-surgery, reducing the need for long-term medications.
Those who undergo removal of one adrenal gland usually live normal, healthy lives without the need for hormone replacement. However, patients who have both glands removed must take lifelong steroid hormone therapy (like hydrocortisone and fludrocortisone) to replace the essential hormones.
Regular endocrinology follow up is essential to ensure hormone levels remain balanced and to manage long-term health.
Conclusion
Adrenalectomy is a safe and effective surgical solution for adrenal gland disorders, including tumors, hormonal imbalances, and cancer. Thanks to advances in laparoscopic surgery, many patients can experience faster recovery, less pain, and minimal disruption to their daily lives.
