Surgery to remove all or part of the large bowel (large intestine)
If you have been advised that you might need a colectomy or that you need to speak to a specialist about problems with your colon, call or book online today to arrange a consultation to discuss private colectomy with a consultant of your choice at Circle Health Group.
This page explains what a colectomy is, what happens during the procedure and what to expect during your recovery.
The colon is a part of your large intestine and, along with the rectum and anus, makes up the last part of your bowel. It starts at the caecum, a pouch that connects to the small intestine, and consists of five parts:
The main function of the colon is to receive digested food from the small intestine and remove water and electrolytes to make a solid stool that can be excreted as waste (poo). It is possible to live without all or part of your colon.
During a total colectomy, the entire colon is removed, and the small intestine is attached directly to the rectum.
A hemicolectomy is the removal of either the descending colon (left hemicolectomy) or the ascending colon (right hemicolectomy).
During sigmoidectomy, the last part of the colon, the sigmoid colon, is removed.
This is where the colon is removed, but the rectum remains in place.
During proctocolectomy, the entire colon and rectum are removed.
A colectomy may be performed to treat several conditions affecting the colon including:
Your consultant will ask you about your symptoms, and medical history and perform a physical examination. They may order tests to look at your colon and check you are fit enough to have surgery. These may include blood tests, electrocardiogram (ECG), X-ray, urine tests and a procedure to examine your colon called a colonoscopy.
At the end of your appointment, your consultant will decide if a colectomy is a suitable treatment for you based on your diagnosis, medical history and general health. They will discuss the type of colectomy you will have and how your surgery will be performed as well as any risks and complications, and what to expect during your recovery.
Your consultant will tell you everything you need to do to prepare for your surgery. If there's anything you're not sure about, or if you have any questions about how to prepare for your surgery, speak to your consultant or call the hospital for advice.
Being well-prepared for your surgery will help to ease any anxiety you may have as well as allow your surgery and recovery to go more smoothly.
Before your surgery, tell your consultant about any medical conditions or allergies you have, and any medication, including over-the-counter medicines you are taking.
Your consultant may tell you to stop taking some medications like blood thinners or non-steroidal anti-inflammatory drugs (NSAIDs) for a few days before your operation. This is to reduce the risk of bleeding during and after your surgery.
Your bowels need to be empty before your surgery. Your consultant will give you instructions on what to eat and drink in the days before your surgery. You will also need to have bowel prep (a laxative or enema to empty your bowels) the day before your surgery.
You will not be able to eat or drink anything from midnight on the day of your operation.
Being in optimal health before your surgery can reduce the risk of complications and speed up your recovery.
To make sure you are as healthy as possible before your surgery:
For a laparoscopic colectomy, your consultant will begin by making between three and five small incisions (cuts) in your abdomen.
A flexible tube with a light and camera is inserted into one of the incisions to allow your consultant to see inside your abdomen. Your abdomen is filled with gas to expand it and make it easier for your consultant to examine your internal organs.
The diseased part of the bowel is located and removed, often along with some of the surrounding lymph nodes.
If possible, the healthy ends of the bowel are joined together. This is called anastomosis. If there isn't enough healthy tissue, your consultant will make an external opening in your abdominal wall called a stoma. Your colon is then diverted to the stoma and faecal waste passes through it into a bag attached to your abdomen (a colostomy). This may be temporary or permanent.
If you are having an open colectomy, your consultant will make an approximately fifteen to twenty cm (six to eight inch) incision in your abdomen.
Your colon and surrounding structures are examined for signs of disease and any diseased areas will be removed.
As with laparoscopic colectomy, your consultant will either join the ends of your bowel together with an anastomosis or create a stoma in the abdominal wall.
Your consultant will be able to give you an estimated recovery timeline based on your individual circumstances.
After your surgery, you will be taken to the recovery room where your breathing, heart rate and blood pressure will be monitored closely until the effects of the anaesthetic have worn off. You will then be taken to your room.
It's normal to experience some post-operative pain in the days following your surgery. You will be given medication to manage this, but please tell a member of your healthcare team if you have any pain.
You will need to eat a soft diet for the first two weeks after your colectomy. Your healthcare team will advise you on which foods you can eat and which to avoid.
Your incision wounds will have dressings in place for the first forty-eight hours after surgery. After this, the outer dressings can be removed, but leave the steri strips in place until they fall off by themselves. Keep your wounds clean and dry and avoid submerging your wounds in water for the first two weeks. Take showers instead of baths, gently clean your incisions with a mild soap, pat dry and leave open to the air.
You can expect to stay in hospital for around seven days after your colectomy.
You will not be able to drive yourself home from hospital, or for at least two weeks after your colectomy. Please make arrangements for someone to come and collect you, or we can organise a taxi if you prefer. Get the all-clear from your consultant and inform your insurance company before driving after your surgery.
How soon you can go back to work after your surgery depends on the type of surgery you had, your individual recovery, and the type of job you do. Most people return to work around four to six weeks after colectomy surgery.
Recovery from colectomy surgery is different for everyone and depends on factors such as the type of surgery, your general health and whether there were any complications during your surgery.
Follow your consultant's instructions carefully during your recovery and call the hospital if you have any questions or are worried about anything after your surgery.
Most people can resume normal daily activities between four and eight weeks after colectomy surgery. You will need to avoid heavy lifting for at least six weeks.
Like all types of surgery, there is a small risk of complications associated with colectomy surgery. Your consultant will explain all the possible risks and complications and answer any questions you may have before your colectomy. Please ask as many questions as you need to ensure that you are fully informed before your surgery and able to make an informed decision.
Possible complications of any surgery include:
Possible complications specific to laparoscopic colectomy include:
Call your healthcare provider immediately if you experience:
Whether you need a colostomy bag after your colectomy depends on whether there is enough healthy bowel to join the cut ends together (anastomosis) during your surgery. If there is not enough healthy bowel, your consultant will divert the bowel to an opening in the abdominal wall and attach a colostomy bag. This may be temporary or permanent. Talk to your consultant about whether they expect you will need a colostomy bag after your colectomy.
Yes. For ulcerative colitis that doesn't improve with other treatments, a total colectomy provides a cure for ulcerative colitis.
Avoid alcohol for at least two weeks after your colectomy. After this, talk to your consultant about when you can safely drink alcohol after your surgery.
A colectomy takes between one and four hours and depends on the type of surgery you have (open or laparoscopic) and what is done during your surgery.
For the first two to three days after your colectomy, you will be given intravenous fluids (fluids into a vein) only. This will gradually progress to drinking clear liquids such as water, black tea, black coffee and clear soups and juices.
When you can start eating solid food, you'll begin with easy-to-digest foods like applesauce, pears, bananas, white rice and pasta before gradually returning to your normal diet. Your healthcare team will advise you on what foods to eat and what to avoid after your colectomy.
