Adrenalectomy is the surgical removal of one or both of the adrenal glands. These small, triangular glands sit atop each kidney and are responsible for producing essential hormones like adrenaline, cortisol, and aldosterone.
In 2026, the vast majority of adrenalectomies are performed using robotic or laparoscopic techniques, allowing for high precision near major blood vessels and a much faster recovery than the "open" surgeries of the past.
1. What is it? Common Names for This Surgery
- Unilateral Adrenalectomy: Removal of one adrenal gland (the most common type). The remaining gland typically compensates for the loss.
- Bilateral Adrenalectomy: Removal of both glands. This requires lifelong hormone replacement therapy.
- Partial (Sparing) Adrenalectomy: Removal of only the diseased portion of the gland, preserving healthy tissue to maintain hormone production.
2. Common Symptoms & Indicators for Consultation
Most patients are referred for an adrenalectomy after an "incidentaloma" (a growth found by accident on a scan) is discovered, or due to symptoms of hormone overproduction:
- Uncontrolled Hypertension: High blood pressure that doesn't respond to standard medications (often a sign of Conn's Syndrome).
- Cushingoid Features: Rapid weight gain in the face ("moon face") and upper back, thinning skin, and purple stretch marks.
- Palpitations and Sweating: Sudden "bursts" of anxiety, racing heart, and severe headaches (classic signs of a Pheochromocytoma).
- Unexplained Weight Loss: Can be a sign of a larger, potentially malignant adrenal mass.
3. List of Associated Diseases and Conditions
- Pheochromocytoma: A rare tumor that secretes high levels of adrenaline/noradrenaline.
- Aldosteronoma (Conn’s Syndrome): A tumor that overproduces aldosterone, leading to low potassium and high blood pressure.
- Cushing’s Syndrome: Excess cortisol production.
- Adrenocortical Carcinoma: A rare, aggressive cancer of the adrenal gland.
- Metastatic Disease: Cancer that has spread to the adrenal gland from another site (commonly the lung or breast).
4. List of Assessment and Screening Tools
Because the adrenal gland is chemically complex, the "workup" is extensive:
- 24-Hour Urine Collection: To measure levels of metanephrines and catecholamines.
- Dexamethasone Suppression Test: To check for excess cortisol.
- CT or MRI with Adrenal Protocol: High-resolution scans that measure the "washout" of contrast to determine if a mass is benign or malignant.
- Adrenal Vein Sampling (AVS): A procedure where blood is taken directly from the veins of both glands to see which one is overproducing hormones.
5. Am I Eligible for Adrenalectomy?
- Tumor Size: Generally, tumors larger than 4 cm are recommended for removal due to increased cancer risk.
- Hormonal Activity: If a tumor is "functioning" (producing hormones), it usually needs to be removed regardless of size.
- Surgical Approach: Most are eligible for Laparoscopic or Robotic surgery. However, if a tumor is very large (usually over 10–12 cm) or invading nearby organs, an "open" surgery may be required.
6. Pre and Post Care Management
Pre-Care (The "Alpha-Blockade"):
- If you have a Pheochromocytoma, you must take specific blood pressure medications (Alpha-blockers and then Beta-blockers) for 7 to 14 days before surgery. This prevents a dangerous "blood pressure spike" when the surgeon touches the gland.
Post-Care:
- Hormone Monitoring: You will have blood tests to ensure your remaining gland is "waking up" and producing enough cortisol.
- Activity: Most patients are walking within 24 hours. Avoid heavy lifting for 4 weeks to prevent hernias at the small incision sites.
- Steroid Supplements: If you had a cortisol-producing tumor removed, you may need temporary steroid pills (Hydrocortisone) while your body adjusts.
7. Days Required for Hospitalization
- Laparoscopic/Robotic: 1 to 2 nights.
- Open Surgery: 3 to 5 nights.
- Recovery: Most people return to work within 2 to 3 weeks.
8. Benefits of the Procedure
- Cure for Hypertension: For many with Conn's or Pheochromocytoma, surgery provides a permanent cure for high blood pressure.
- Cancer Prevention: Removing "suspicious" masses early prevents the spread of adrenal cancer.
- Symptom Resolution: Rapid improvement in anxiety, weight gain, and muscle weakness once hormone levels are normalized.
A grounded insight: The adrenal gland is tiny (about the size of a walnut), but it’s the body's "chemical plant." Removing it requires a delicate touch—especially with the robotic approach—but it is one of the most effective ways to "reset" your body's internal balance.
Are you preparing for a "functioning" tumor removal, or was your growth found incidentally on a scan?
