This leaflet explains about the procedure known as Sigmoid Colectomy.
Before your operation you may have scans and x-rays to assess the extent of the cancer. While waiting for your operation it is important to prepare yourself physically. If you can, continue eating a normal diet and take gentle exercise. If you smoke, try and stop before your operation
Before the operation you will be asked to sign a consent form to say that you understand what the operation involves.
You may have to attend the pre-admission clinic where routine pre-operative tests take place e.g. blood tests, chest x-ray, ECG (electrocardiograph – trace of your heart); listening to your chest and checking your blood pressure. This is to make sure your admission to hospital is as smooth as possible. During this appointment you may see the nurse specialist who will be able to answer any of your questions.
Your bowel will need to be clear before your operation. You may be given some medicine to clear your bowel and encouraged to drink clear fluids only for one day before your operation. This will help to clean your bowel and reduce the risk of dehydration before the surgery.
You will be given:-
- 2 x Bisacodyl tablets and 2 x Picolax sachets (powerful laxative drink) – to be taken the day before the operation.
- It is important to drink plenty of fluids while taking the laxatives to prevent dehydration. Fluids allowed include water, squash or tea/coffee (without milk)
- You may drink plain water (not fizzy) for up to 2 hours before surgery.
Your Colorectal CNS or your Consultant will advise on the appropriate bowel preparation before your surgery.
If you have been given energy drinks (Nutricia Pre-Op), drink them as soon as you wake up on the day of surgery before you come to the hospital.
Please do not eat sweets or chew gum on the day of surgery
Do not take your medications on the day of surgery. Bring all your medication with you to the hospital and the Doctors or nurses will advise you which medications to take.
Anatomy of the bowel
This operation involves the removal of the left side of the bowel called the sigmoid. After removal of the diseased portion the two free ends of bowel will be joined together to restore intestinal continuity and to help the stool to pass through as normal. This is called an Anatomises.
The sigmoid colon is mainly for the storage of waste matter, thus removing this part has little effect on opening of your bowels, although your stool may be a little softer. You may also find that you open yourbowels more frequently than before because the capacity to hold motions is smaller.
BeforeAfter
There is a possibility that an ileostomy (stoma) may be formed to allow the join to heal and prevent complications. A stoma is anartificial opening through the wall of the abdomen to collect the waste matter (either faeces or urine) into a bag instead of passing through your bottom.
A bag fits over this to collect your stool and is completely disposable. The bag will need to be changed on a daily basis.
Stoma is the Greek word for "mouth" or "opening".
This kind of stoma is usually temporary; if the growth in the bowel is too low then it may have to be permanent.
You may need some further treatment after your operation, in the form of chemotherapy. The piece of bowel removed during surgery will be examined by the pathology department; your further treatment will depend on the basis of these results. It may take a few weeks before the results of these tests are completed.
If an ileostomy is required, further treatment may slightly delay the reversal of this. The stoma care nurse will help and support you to manage your stoma and provide you with any advice that you may need.
If possible your surgery may be performed using a
laparoscopic assistedapproach. Laparoscopic colorectal surgery also known as ‘keyhole surgery’ involves inserting laparoscopic (‘keyhole’) instruments through a number of small incisions in the abdomen (tummy).The instrument has a camera attached which projects images on the TV monitor to help with the dissection and thereby performing the entire surgery through a slightly larger incision .
The main aim of having this type of surgery is to:
-Reduce hospital stay, minimise hospital infection
-Quicker recovery
-Minimise scarring
-Reduce discomfort following surgery
Most operations are successful. However, every procedure has risks and potential complications. The risks and complications that are most relevant to the operation are listed below.
If there is anything you are unsure about you can discuss this with your Doctor or Nurse.
Choosing not to have this operation will depend on your diagnosis following investigations but may include the continuation or worsening of the symptoms possible obstruction of the bowel leading to emergency hospital admission.
The risks and complications can be divided into three areas:-
- Complications of the anaesthesia
- General complications of any surgery
- Specific complications of this operation
1. Complications of the anaesthesia
Your anaesthetist will discuss to you about the risks of an anaesthetic.
2. General complications of any operation
- Pain – this can occur with any operation. Post operatively the pain team will regulate the pain relief to fit your personal needs.
- Bleeding – this can occur during or after the surgery. If this happens you may need a blood transfusion or very occasionally another operation may be required. If you have any religious or personal objectionsdiscuss this with your doctor before the surgery.
- Infection in the surgical wound – this would usually be treated with antibiotics or occasionally further surgery (risk: 3-7 in 100).
- Unsightly scarring - this is more likely if the wound has become infected.
- A hernia – this can occur in the incision scar when the deep muscles fail to heal. The hernia will appear as a bulge around the incision line and is called an incisional hernia. If this causes problems, you may need another operation.
- Blood clots – These can occur in the legs (thrombosis) and can move to the lungs to cause breathing problems. You will be asked to wear anti-thrombosis tights (long socks) and will be given blood thinning medication to reduce the risk. Exercising your legs and moving around as much as you are able to can help reduce the risk of blood cots.
- Difficulty passing urine – You will have a catheter inserted at the time of the operation which will remain in place for approximately 1-2 days. Occasionally, when the catheter is removed, you may have difficulty passing urine. This is more common in men and/or if you have had difficulties passing urine prior to the operation.
- Chest infection – the physiotherapist will give you deep breathing exercises to help prevent a chest infection.
3. Specific complications of this operation (sigmoid colectomy)
- Anastomotic leak – this is a serious complication which occurs if the joined ends of the bowel fail to heal adequately, leaving a hole (leak) at the join (anastomosis). Treatment with antibiotics and resting the bowel generally helps with the healing.
If this happens, you would probably require a further operation.
If you have a stoma made as part of the operation you should be protected from the effects of any leaks.
- Adhesions – are bands of scar like tissues that form inside the abdomen. This can occur following any operation on the abdomen and does not usually cause any problems. However, it can sometimes lead to bowel obstruction many years later.
- Sexual disturbance – the nerves that supply the sexual organs in both men and women run very close to the rectum. When the cancer is removed these nerves can be damaged which may lead to impotence in men and vaginal dryness in women. Impotence following rectal cancer surgery is one of the licensed indications for receiving Viagra (a drug used to overcome impotence).
Following surgery you will go back to the ward. The nurse on the ward will carry out regular observations on you. You will be allowed to drink fluids freely and to eat when you feel able.
When you wake up you will find that you are attached to several tubes. These may be: -
- A drip in your arm or neck, which gives you the extra fluids that you require.
- A PCAS (patient controlled analgesia system), which is another tube in the arm or in the back that slowly releases painkiller
- An NG tube (a nasogastric tube), which is a tube in your nose that goes down the back of your throat into your stomach, this tube helps prevent you from feeling sick and vomiting
- A catheter (tube), into your bladder to help drain and measure the amount of urine you pass.
- Drainage tubes to help clear any oozing fluid around the operation site.
These tubes are inserted while you are under anaesthetic and will be removed over a period of days after the operation. Depending on the recovery you will be in hospital for 4-6 days.
If your bowel function is normal you can eat and drink soon after your surgery. If the bowel function is slow to start food and drink may be restricted for a few days.
To speed up your recovery, you will be given 3 supplements drinks each day. These will be given for 3 days after your surgery.
It is important to try and move around soon after the operation. Becoming mobile will help you to recover quickly from the operation and also reduce the risk of complications.
After the operation, rest is very important as part of the recovery process, so it is advisable to restrict the number of visitors coming to see you so you don’t get overtired.
Visiting time is between 11.00am – 12.00pm and 4.00 – 8.00pm. Only 2 visitors are allowed at a time.
The medical staff will be able to advise you if some movements are restricted, like kneeling or bending down. This may last for a short period of time, as you get better you will be able to resume your daily activities.
For the first week or so you will feel tired and weak when you get home. It is therefore important that you rest although it is not good for you to stay in bed all the time. You should try gentle exercise first like walking around the house or to the end of the street. Your appetite may be reduced so try eating little and often to begin with.
For most people it will take 6-8 weeks to recover from this type of operation. You may feel some pain and ‘twinges’ around your wound for several months. This is normal as it takes a while for full healing to take place. Taking a mild painkiller will help you feel better and help with recovery.
For the first six weeks you are advised not to lift anything heavy such as shopping or wet washing, and not to do anything strenuous like digging the garden or mowing the lawn.
You should not drive until you can do an emergency stop without hesitation that your wound will hurt. To test if you could do an emergency stop, lift both feet off the ground at the same time. If it does not cause you abdominal pain you would be able to do an emergency stop. It is advisable to check your car insurance for any clauses regarding driving after an operation.
The length of time before you are fit to return to work will be individual and dependent on the type of work you do.
When you get home you may find that your bowel habit is still unpredictable. When you have had some of your large bowel removed you may find your stools are slightly loose, over time this will resolve itself. You may also find that you open your bowels more frequently than you did before your surgery. This could be anywhere between 1-4 times per day. If your bowel habit does not settle, there are medications that can help. If you have any queries ask the specialist nurse or your doctor.
The length of time before you are fit to return to work will be individual and dependent on the type of work you do.
You should not drive until you can do an emergency stop; you have to be able to do one with out hesitation that your wound will hurt. To test if you could do an emergency stop, stomp your foot, if it does not cause you abdominal pain you would be able to do an emergency stop. It also may be advisable to check your car insurance for any clauses regarding driving after an operation.
Once you have recovered from your operation there is no reason why you can’t go back to your normal sex life. However, operations on the rectum can cause damage to the nerves that connect to the sexual organs. If there is damage men may find in difficult to get or maintain an erection, and may have problems with ejaculation. Women may experience pain when having sex or a lack of lubrication fluids (natural fluids in the vagina). If you do have problems talk to you doctor or specialist nurse.
Doctors use a system to describe the different stages of cancer of the large bowel – Dukes’ staging. The staging system is based on the depth the tumour has invaded through the bowel wall and whether any cancer has spread to the lymph nodes (lymph node metastasis).
After your operation the histopathologist will examine the cancer under the microscope, we usually have the results within 14 days and will then be able to tell you about the stage of your bowel cancer.
Dukes’ Stage /Extent of cancer
Dukes’ A / The cancer is confined to the bowel wallDukes’ B / The cancer has spread through the full thickness of the bowel wall, but the lymph nodes are not affected.
Dukes’ C / The cancer has spread to the lymph nodes. The lymph nodes are part of the lymphatic system, which is part of the body’s natural defence against infection. This is one of the first places the cancer can spread to.
