The treatment of a pheochromocytoma is a highly structured medical process that primarily culminates in the surgical removal of the tumour. Because these adrenal tumours produce excessive amounts of adrenaline and noradrenaline, any intervention especially surgery carries a significant risk of triggering a life threatening hypertensive crisis. Therefore, the clinical approach in the United Kingdom follows a strict three phase protocol: medical stabilization, surgical resection, and long term postoperative monitoring. In almost all cases where a pheochromocytoma is identified and confirmed through biochemical testing, surgery is considered the definitive and necessary treatment. This is because the tumour poses a constant risk to the cardiovascular system, and conservative management alone is rarely sufficient to prevent serious complications such as stroke or heart failure.

Preoperative stabilization and medical preparation
Before a patient can safely undergo surgery to remove a pheochromocytoma, they must undergo a period of intensive medical preparation. This phase, often lasting two to three weeks, is designed to block the effects of the excess hormones and expand the patient’s blood volume. The primary medications used are alpha blockers, such as phenoxybenzamine or doxazosin. These drugs relax the blood vessels, allowing blood pressure to drop and the constricted vascular system to expand. Once the alpha blockade is established, beta blockers may be added to control heart rate and prevent palpitations. It is a critical safety rule in UK clinical practice that beta blockers must never be started before alpha blockers, as doing so can cause a paradoxical and dangerous rise in blood pressure. During this time, patients are often encouraged to increase their salt and fluid intake to counteract the dehydration that typically occurs with high adrenaline levels. The NHS guidance on phaeochromocytoma emphasizes that this preparation is the most important factor in ensuring a safe surgical outcome.
When is adrenal surgery required?
Adrenal surgery is required for almost every patient diagnosed with a pheochromocytoma. Unlike some other adrenal growths that may be monitored over time, a pheochromocytoma is considered an “active” tumour that will continue to produce dangerous levels of hormones as long as it remains in the body. Surgery is indicated as soon as the patient is medically stabilized and any associated cardiovascular issues have been addressed. The goal of the surgery is to completely remove the affected adrenal gland, a procedure known as an adrenalectomy. While the majority of these tumours are benign, the unpredictable nature of hormone release means that surgical removal is the only way to eliminate the risk of sudden hypertensive crises and protect the heart and brain from long term damage. In cases where the tumour is part of a genetic syndrome and affects both adrenal glands, surgeons may attempt “cortical sparing” surgery to preserve some adrenal function and avoid lifelong hormone replacement therapy.
Surgical approaches: Laparoscopic vs. Open surgery
The choice of surgical technique depends on the size and location of the tumour, as well as the patient’s overall health. In the United Kingdom, the vast majority of adrenalectomies are now performed using laparoscopic or “keyhole” surgery. This approach involves several small incisions through which a camera and specialized instruments are inserted. Laparoscopic surgery is associated with less pain, shorter hospital stays, and a faster return to normal activities. For very large tumours, or cases where there is a high suspicion of malignancy and invasion into surrounding tissues, an open surgery may be necessary. Open surgery involves a larger incision, usually under the ribs or on the side, to allow the surgeon better access to the tumour and nearby organs. Both methods are performed under general anaesthesia by a specialist endocrine or urological surgeon who has extensive experience in managing these rare cases.
Intraoperative management and patient safety
The surgery itself is a high risk period because handling the adrenal gland can cause a massive “dump” of hormones into the bloodstream. To manage this, an anaesthetist with specific expertise in endocrine surgery monitors the patient’s vitals second by second. They use fast acting intravenous medications to instantly counteract any sudden spikes in blood pressure or heart rate that occur when the surgeon manipulates the tumour. Once the blood supply to the tumour is clamped and the gland is removed, the opposite problem can occur: the patient’s blood pressure may drop sharply because the source of excess adrenaline is gone. The surgical team prepares for this by providing intravenous fluids and, if necessary, medications to support blood pressure. This delicate balance of monitoring and rapid intervention is what makes having the surgery in a specialized UK medical centre so important for patient safety.
Postoperative recovery and hospital stay
After the surgery, most patients spend at least 24 to 48 hours in a high dependency unit or an intensive care bay for close monitoring. This ensures that their blood pressure remains stable and that their remaining adrenal gland is functioning correctly. Most patients who undergo laparoscopic surgery can expect to stay in the hospital for three to five days, while open surgery may require a slightly longer stay. Pain is managed with standard analgesics, and patients are encouraged to begin walking as soon as possible to prevent blood clots. In the weeks following the surgery, the body must adjust to the lower levels of adrenaline. Some patients may feel tired or experience temporary low blood pressure as their system resets. A follow up appointment is usually scheduled for six weeks post surgery to check hormone levels and ensure that the cardiovascular symptoms have resolved. For further information on surgical recovery, the British Association of Endocrine and Thyroid Surgeons offers resources for patients undergoing adrenal procedures.
Management of malignant and metastatic cases
In the approximately 10 percent of cases where the pheochromocytoma is malignant and has spread beyond the adrenal gland, surgery remains a vital tool but is often combined with other treatments. “Debulking” surgery may be performed to remove as much of the tumour tissue as possible, which helps to reduce the overall hormone load on the body. Other treatments available in the UK include MIBG therapy, which uses a radioactive molecule to target and destroy cancer cells, and specialized chemotherapy or targeted drug therapies. While metastatic pheochromocytoma is more difficult to cure, these treatments can control the growth of the cancer and manage the symptoms of hormone excess for many years. These complex cases are managed by a multidisciplinary team in a specialist tertiary referral centre to ensure the patient has access to the most advanced therapies and clinical trials.
Conclusion
The primary treatment for a pheochromocytoma is the surgical removal of the adrenal gland, a procedure that is required to eliminate the source of dangerous hormone surges. Successful treatment depends on a careful period of medical preparation using alpha and beta blockers to stabilize the heart and blood pressure. Most surgeries in the UK are performed using laparoscopic techniques, ensuring a safer and faster recovery. Following surgery, lifelong monitoring is essential to catch any recurrence early and manage long term health. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
Is adrenal surgery always done as an open operation?
No, most adrenal surgeries in the UK are now done laparoscopically (keyhole), which involves smaller incisions and a quicker recovery.
Will I need to take hormone tablets after my surgery?
If only one adrenal gland is removed, the remaining gland usually produces enough hormones so that tablets are not needed; if both are removed, lifelong replacement is required.
How long is the recovery period after surgery?
Most patients return to light activities within two weeks and can return to work within four to six weeks, depending on the type of surgery and their job.
Why is salt important before my surgery?
Increasing salt and fluids helps expand your blood volume, which often drops significantly after the tumour is removed.
Can the tumour come back after it is removed?
There is a small risk of recurrence, which is why annual hormone testing is recommended for the rest of your life.
What happens if the tumour is found to be malignant after surgery?
If the tumour is malignant, your specialist team will discuss further treatments such as radiotherapy or MIBG therapy to manage any remaining cells.
Do I need a special diet after adrenal surgery?
There is usually no specific diet required after recovery, although maintaining a healthy weight and low salt intake may be advised if you have lingering high blood pressure.
