General surgery abroad: when you can fly home, and what to check first

Five things are easier to arrange before you leave than from a hospital bed abroad.

• Fitness to fly and airline clearance. Ask the operating clinic, before you go, for a letter that will confirm the operation, its date and your fitness to fly, and ask your airline whether it needs medical clearance for a passenger who has just had surgery. The Civil Aviation Authority explains that a passenger may be asked for proof of fitness to fly, that an airline with concerns about a condition asks for a further form, and that it may ask for medical proof, often a doctor's note. Airlines can also require that you travel with a companion.
• Travel insurance. Tell your insurer, before you buy a policy, that you are going abroad for a planned operation, and ask in writing what is covered: a complication abroad, a longer stay, a return trip and medical repatriation. The NHS states that most travel insurance policies will not cover you for planned treatment abroad, so you may need specialist cover, and GOV.UK advises declaring existing conditions and pending treatment, because failing to declare something may invalidate a policy.
• Medicines. Rules on what you may carry differ by country, especially for controlled painkillers. GOV.UK advises checking the rules of the country you are going to with its embassy before you travel, and carrying medicine in your hand luggage with the prescription or a letter from your doctor to prove it is yours. Ask the clinic for a printed list of anything it prescribes, with the generic names.
• Documents to bring home. Ask for the operation note, the discharge summary, the details of any mesh or implant used, a list of the medicines you were given, the follow-up plan and itemised invoices, in a language your own doctor can read.
• Someone with you. The NHS advises having an adult available to help you for at least 24 hours after a general anaesthetic or an epidural, and says you will not usually be able to drive yourself home after surgery. Abroad, that person also deals with the hospital, the hotel and the airline if you cannot.

Ask before you book, not after: who treats a complication once you are home, on what terms and at what cost, and get the answer in writing. The NHS advises anyone considering treatment abroad to be clear about how aftercare will be coordinated, to think about how medical staff abroad and at home will exchange records, and to stay where you were treated for a suitable length of time before travelling home.

Your own doctor may know nothing about your operation. Bring the documents listed above to your first appointment; without an operation note and a discharge summary, a doctor at home is treating a wound without knowing what is under it.

Wound checks, stitches, drains and mesh. Before you leave hospital, ask who removes stitches, clips or drains and when, how long dissolvable stitches take to go, how to care for the wound, and which mesh or implant was used. The NHS puts exactly these questions to patients leaving hospital. If the answer is a clinic in another country, ask which clinician at home will do it instead.

A return trip. If the operating surgeon needs to see you again, that means a flight, a stay and time off work. Ask whether the quote includes any of it.

Warning signs after a flight. Seek urgent care where you are; do not wait for a call back from the clinic abroad. The NHS tells patients recovering from a hernia repair to get urgent help if:

• the wound has pus coming out of it, or is painful, swollen, warm or red;
• you have a high temperature, or feel hot, cold or shivery;
• your tummy is swollen or painful and getting worse;
• a lot of blood is coming out of the wound;
• you have a throbbing or cramping pain in a leg, or one leg is swollen;
• you are breathless, or more breathless than usual;
• you have coughed up spots, flecks or streaks of blood.

Chest pain, severe difficulty breathing or coughing up more than a few flecks of blood are emergencies: call the emergency number where you are. They can be signs of a clot in the lungs.

Ask these questions in writing before you pay a deposit. A clinic that will not answer them in writing has answered.

• Who will operate, under which name and registration number, and on which public register of the medical regulator in that country you can check it.
• Whether that surgeon will examine you before the operation, and who covers their patients out of hours.
• Which operation is proposed and why, which alternatives were considered, and why they were rejected.
• What the quote includes and excludes: tests, the anaesthetist, the hospital stay, medicines, follow-up appointments and the treatment of a complication.
• How many nights the clinic expects you to stay before flying, and how that compares with the Civil Aviation Authority's figure for your operation.
• Which hospital the operation takes place in, and what happens if you need intensive care.
• Whom you can reach after you return, in which language, through which channel and for how long.
• Which documents you will be given when you leave, from the list above.

The NHS checklist for treatment abroad names the warning signs to watch for in the clinic itself: a hard sell, a lack of information, pressure to decide quickly, no discussion of possible complications and no mention of aftercare.
