Preparing for your operation

Information about what to expect and how to prepare for surgery, and the operation guides for each procedure.

Before your operation

In most cases you will be admitted on the morning of your surgery. The hospital’s admissions department will confirm the time and the place of admission with you beforehand. Please bring a list of your current medications, any recent test results or imaging that you have been given, and your medical aid details. You should shower on the morning of surgery, leave jewellery and valuables at home, and arrange for a responsible adult to accompany you home after discharge.

To make anaesthesia safe, your stomach must be empty at the time of surgery. You should therefore have nothing to eat or drink (nil per os) from midnight before your operation. If your surgery is scheduled for later in the day, you may be permitted to have solids until six hours before the planned time of surgery and clear liquids until two hours before, and you will be told if this applies to you. Most patients should continue to take their usual regular medications on the morning of surgery with a small sip of water. This applies in particular to medications for blood pressure, heart conditions, asthma, thyroid disease, and reflux. The exceptions are anticoagulants (blood thinners), antiplatelet agents (such as aspirin or clopidogrel), insulin, and tablets used to lower blood sugar (hypoglycaemic agents). These medications require specific instructions about when to stop and when to restart, and these will be given to you individually. Please do not stop any medication on your own initiative, and tell us about every medication you take, including over-the-counter products and herbal remedies.

Special care is needed if you are taking semaglutide (Ozempic, Wegovy, Rybelsus) or a similar medication, such as liraglutide, dulaglutide, or tirzepatide, whether prescribed for diabetes or for weight loss. These drugs slow the emptying of the stomach, so that food may remain in the stomach despite a conventional fasting period. This increases the risk of stomach contents entering the lungs during anaesthesia. Patients on these medications will therefore require a longer period of fasting, and may be asked to follow a modified diet before surgery or to adjust the timing of their doses. Please inform my rooms and the anaesthetist as early as possible, and well before the day of surgery, so that individual instructions can be provided.

If you develop a cough, fever, or any other illness in the days before your operation, or if you have any uncertainty about these instructions, please contact my rooms as soon as possible. In some cases the operation may need to be postponed, and it is far safer to raise concerns beforehand than on the day of surgery.

Operation guides

Choose your procedure to read about the operation and about going home afterwards.

Thyroid surgery is a well-established operation with a low overall complication rate. The usual hospital stay is a single night, which allows for assessment of the wound, voice, and calcium levels before discharge. Surgical drains are rarely required. Patients with significant co-morbidities, or those in whom the operation is anticipated to be technically complex, may be admitted to a high care unit for closer postoperative monitoring. This is a precautionary measure and is applied selectively.

The recurrent laryngeal nerves, which control the vocal cords, lie in close relation to the thyroid gland. Intra-operative nerve monitoring is used routinely to assist in identifying and preserving these nerves. Despite meticulous technique, some patients experience a change in voice after surgery, such as hoarseness, reduced projection, or vocal fatigue. These symptoms may reflect nerve irritation or the effects of the endotracheal tube used during anaesthesia. Most changes resolve within weeks to a few months. Permanent voice change is uncommon.

Following total thyroidectomy, the parathyroid glands, which regulate calcium, may temporarily under-function, resulting in hypocalcaemia. This typically presents with perioral or fingertip tingling, or muscle cramping. Calcium levels are monitored after surgery, and the condition is managed effectively with calcium and, where necessary, vitamin D supplementation. In the majority of patients parathyroid function recovers and supplementation can be discontinued. A small proportion require long-term treatment. Patients who develop these symptoms after discharge should take their prescribed supplements and contact the rooms.

Wound haematoma is an uncommon complication, but it requires prompt recognition because neck swelling can compromise the airway. It generally occurs within the first 24 hours, which is a principal reason for the overnight stay. Patients who notice rapid neck swelling, tightness, or difficulty breathing should alert the nursing staff immediately. The risk of wound infection is low. Individual risk varies with the indication for surgery, the extent of the operation, and the patient’s general health, and these factors are discussed in detail at the pre-operative consultation.

Patients from across South Africa and abroad

Prof Panieri regularly reviews cases and consults with patients who live outside Cape Town: from across South Africa and the rest of Africa, from Mauritius, the United Kingdom, Italy, France and Canada, among other countries.

South Africa offers outstanding quality medical care, often at a significantly lower cost than in high-income countries, with experienced specialist teams and modern private hospitals.

  1. Remote consultationAn initial opinion can often be given remotely, after review of scans, pathology and clinical records, and in discussion with the patient and their own doctors.
  2. A clear planPatients receive an assessment of whether surgery is needed, what it would involve and when it should happen. Some are advised that treatment close to home is the best option.
  3. Surgery in Cape Town when appropriateWhere surgery is advised, it is arranged at UCT Private Academic Hospital, with follow-up coordinated with the doctors who look after the patient at home.
