Introduction

This booklet is about the surgery to remove the lymph nodes from your groin. It aims to give you an idea of what is likely to happen and how long you can expect to be in hospital. It is also important that you know about minor problems which are common after this operation, and more serious problems that can occasionally occur. The section “What problems can occur after the operation?” describes these and we would particularly ask you to read this; the headings from this section will also be included in the consent form you will be asked to sign. You can help to reduce certain risks by closely following the advice of your surgeon and his/her team.

What is a groin node dissection?

It is a surgical procedure performed under a general anaesthetic in which the lymph nodes in the affected groin are removed.

Why do I need a groin node dissection?

The doctors have decided that you require a groin node dissection because on examination of your groin they found enlarged lymph node/s. The lymph node is part of the lymphatic system that runs alongside the bloodstream.

The lymph system is part of the immune system that protects the body against diseases. The system contains lymph fluid, lymph nodes and lymph ducts.

The nodes have an important role in draining and filtering such things as bacteria, viruses and cancer cells. When these reach the lymph nodes the nodes become large and swollen. The doctor may have taken a sample from the node or you may have had a CT scan to determine the cause of the enlarged node. With these results the doctor has decided that the lymph nodes need to be removed. Removing these nodes may reduce the chance of cancer cells spreading to different parts of the body (metastases).

What happens before the operation?

On the day of surgery, you will not be able to eat or drink anything immediately before your surgery, because an empty stomach is important for a general anesthetic. You should have no food, milk or carbonated drinks for 6 hours before the operation, but you may drink clear fluids until 2 hours before. You should have a bath or shower, remove make-up, nail polish, jewellery and piercings (e.g., earrings and body jewellery). The body hair at the surgical site may need to be removed. Wedding rings can stay in place. Contact lenses, false teeth etc. can be removed just before you go to the operating theatre.

You will attend a pre-operative assessment prior to your scheduled surgery.

This will involve additional investigations (if required) i.e. blood tests, ECG and you may have a clinical review/assessment from an anesthetist.

What about the anaesthetic?

A general anaesthetic is usually given by injection into your hand or arm. The general anaesthetic is one of the main concerns for patients, many feel they are handing over control of their life to another person. This worry is understandable, but modern anaesthetics are very safe, and serious complications are uncommon.

What does the procedure involve?

The surgeon will make an incision (cut)  in your groin and inner upper thigh above the lymph nodes that are to be removed. The lymph nodes are then removed, also the nearby lymphatic channels and surrounding soft tissue. The tissue removed during surgery is sent off to be analysed. A fine tube is then placed within the wound to drain away any excess blood or lymph fluid that may collect. The incision is stitched with either soluble or removable stitches and covered with suture strips (paper tape) and a dressing.

What happens after the operation?

You will probably feel some pain for the first few days. Suitable pain killing tablets, suppositories or injections will be prescribed. It is important to take painkillers if you need them so that you are able to move around easily, preventing blood clots and chest infection. Please tell a nurse if you are in pain. When you are allowed out of bed you will be expected to elevate (raise) your leg when you are not moving to help reduce swelling.

You will be able to eat and drink as normal on return to the ward following surgery. Occasionally you may have a ‘drip’ in your arm to replace any fluid that you may need. If so, this usually can be removed on the day of surgery or the day after depending on how well you tolerate drinking fluids.

You will be required to keep your wounds and dressings dry, therefore you will need to have a head-to-toe wash and not shower or bath for two weeks. The wound drain will remain in until there is minimal drainage, this is normally 7 to 10 days, and then will be removed. Your wound dressings will also be changed.

Discharge from hospital

The surgical team will review you on a daily basis with a view to discharge being arranged for you within 7 to 10 days after your operation, when you are up and about eating, your drain has been removed and you are comfortable.

Please arrange for someone to collect you and to help out at home for a few days. You will be given medication to take home with you;  these will usually be painkillers. Please follow the instructions on the packet.

Occasionally, if it continues to drain, you may be discharged home with the drain still in place. The nurse will teach you how to measure and record the daily drainage in the drain and you will be asked to telephone the ward daily with the amount. When the drainage is minimal, you will need to return to the dressing clinic or Main Outpatients on Level 6 and have the drain removed.

We will give you an outpatient appointment at our plastic surgery dressing clinic Main Outpatients on Level 6 for one week after you have been discharged so that we can check your wound and take out any removable stitches you might have. Further appointments may be required depending on how well your wound has healed. You will also be given a follow- up appointment with your consultant’s team.

What problems can occur after the operation?

Seromas (tissue fluid) and haematomas (blood)

Sometimes tissue fluid and blood can collect within the wound. Treatment is not always necessary, however, if there is too much fluid it may need to be drained using a needle and syringe.

Infection/wound breakdown

Patients may develop a wound infection that requires antibiotics or an area of wound breakdown that requires regular dressings until it heals. Infection will delay the healing process and scars are likely to be worse.

Lost or decreased sensation

Sometimes the nerve supplying sensation to your inner thigh may be stretched or damaged during the surgery. The loss of sensation can extend to the knee and may be temporary but for some patients it may persist.

Lymphoedema

It is common to have swelling after surgery in your groin and thigh/leg for 2 to 3 months. You can help reduce the swelling in your groin and thigh/leg by ensuring you gradually increase your mobility and raise your leg whilst resting. However, there is the possibility that this swelling may continue for longer than the usual post-operative period, and this is known as lymphoedema. If this occurs, you may be required to wear a compression stocking to help reduce the lymphoedema. If this condition persists, there are ways of controlling and treating it.

Deep Vein Thrombosis (DVT)

Deep Vein Thrombosis is a possible problem, but is uncommon. If you are at particular risk, then special precautions will be taken to reduce the risk. Moving your legs and feet as soon as you can after the operation and walking about early, all help to stop thrombosis occurring.

The risks of a general anaesthetic

General anaesthetics have some risks, which may be increased if you have chronic medical conditions, but in general they are as follows:

Common temporary side effects (risk of 1 in 10 to 1 in 100) include bruising or pain in the area of injections, blurred vision and sickness (these can usually be treated and pass off quickly).

Infrequent complications (risk of 1 in 100 to 1 in 10,000) include temporary breathing difficulties, muscle pains, headaches, damage to teeth, lip or tongue, sore throat and temporary difficulty speaking.

Extremely rare and serious complications (risk of less than 1 in 10,000) include severe allergic reactions and death, brain damage, kidney, heart and liver failure, lung damage, permanent nerve or blood vessel damage, eye injury and damage to the voice box. These are very rare and may depend on whether you have other serious medical conditions.

What should you do if you develop problems? 

If you develop any problems, then please contact

Main outpatients Dept (Level 6) on 01752 438406

Signs of problems to look out for include:

• Severe pain in the groin/thigh

• Very high temperature (above 38ºC)

• Redness/heat/excessive swelling of the groin/thigh

• A lot of fluid/pus/blood coming from the wound

• Offensive smell from wounds

• Pain/swelling in calves

When will I be back to normal?

Bathing/showering

You will be unable to shower or bath for the first two weeks or until the wounds are healed. Once they are healed you may bath/shower as normal.

Work/general activities

Increase your activities slowly, ensuring you elevate/raise your leg whilst resting. Most patients’ wounds have healed within 2-4 weeks and you should be able to resume a normal lifestyle within 6-8 weeks after the operation.

Sport

We advise you not to start any strenuous activity such as aerobics, squash, running, swimming and horse riding for 8-12 weeks after your operation.

Driving

Ideally you should avoid driving for 6-8 weeks after the operation. All wounds should be healed and you should feel confident in performing an emergency stop. If in doubt, seek medical advice or check with your insurance company that your policy is valid.

Long term advice following lymph node dissection

The following advice will help reduce the risk of swelling in your leg, and related problems. After the operation, the drainage of lymph fluid may be altered, which could make your leg more prone to swelling. This is usually temporary but some patients may have permanent swelling following the surgery, see section on ‘Lymphoedema’. If you also have a break in the skin, you may be more prone to infection.

Exercise / using your leg

Muscle activity will help stimulate the flow of lymph fluid, so it is important that you increase your mobility gradually and steadily, ensuring you initially elevate your leg whilst resting.

Skin Care

It is important to ensure your skin is kept intact and avoid any cuts or abrasions to reduce the chances of infection.

To reduce your chances of any problems we recommend you:

• Avoid injections in the affected leg

• Avoid acupuncture treatments on this leg

• Wear heavy duty boots when doing heavy gardening

• Avoid letting your skin become dry and cracked by using moisturisers regularly

• Use an electrical razor or cream for shaving your legs to avoid nicking the skin

• Avoid wearing clothing with elastic or constricting bands (especially undergarments and socks)

• Use sun block SPF30 to avoid getting sun burnt

• Avoid having very hot baths and saunas

• Use insect repellent when abroad

• Use nail clippers instead of scissors when cutting nails

• If you cut your affected leg or foot, ensure you clean and cover the area immediately

• Observe the area for redness, swelling and warmth and if this lasts for 24 hours or more you may have an infection and you will need to contact your GP

We would appreciate any comments you have regarding this information and how beneficial it has been for you.
