Gastrectomy is the removal of part or all of the stomach.
There are three main types of gastrectomy:
Removing the stomach doesn’t remove the body’s ability to digest liquids and foods. However, a few lifestyle changes after the procedure may be needed.
Gastrectomy is used to treat stomach problems that are not helped by other treatments. Your doctor may recommend a gastrectomy to treat:
Some types of gastrectomy can also be used to treat uncontrolled obesity. By making the stomach smaller, it fills more quickly. This may help you eat less. However, gastrectomy is only an appropriate obesity treatment when other options have failed. Less invasive treatments include:
All surgeries have risks. These include:
To reduce these risks, answer your doctors’ questions fully, prior to surgery.
Gastrectomy also has its own particular risks. These include:
Complications are typically minor. They can usually be fixed with medications or further surgery.
Major complications are more common in those undergoing gastrectomy for cancer. According to the National Health Service (NHS), this is because they are typically elderly and in poor health (NHS , 2011).
Prior to surgery, you’ll undergo several tests. These will ensure you are healthy enough for the procedure. You will undergo:
During these appointments, tell your doctor if you are taking any medications. Be certain to include over-the-counter medicines and supplements. You may have to stop taking certain drugs prior to surgery.
You should also tell your doctor if you are pregnant, believe you could be pregnant, or have other medical conditions, such as diabetes.
If you smoke, you should quit. Smoking adds extra time to recovery. It can also create more complications.
There are two different ways to perform gastrectomy. All are performed under general anesthesia. This means you will be in a painless sleep during the operation.
This involves a single large incision. Your surgeon will pull back skin, muscle, and tissue to access your stomach
This is a minimally-invasive surgery. It uses small incisions and specialized tools. It involves less pain and a quicker recovery time. It is also known as “keyhole surgery” or laparoscopically assisted gastrectomy (LAG)
Laparoscopic gastrectomy is usually preferred to open surgery. It is a more advanced surgery with a lower rate of complications. However, according to the NHS, open surgery is more effective at treating stomach cancer and removing affected lymph nodes. (NHS , 2011)
There are three major types of gastrectomy.
Your surgeon removes the lower half of your stomach. If cancer cells are present, your surgeon may also remove the nearby lymph nodes.
In this surgery, your duodenum will be closed off. Then the remaining part of your stomach will be brought down and connected to your bowel. The duodenum is the first part of the stomach.
Also called total gastrectomy, this procedure completely removes the stomach. Your doctor will connect your esophagus directly to your small intestine. The esophagus normally connects your throat to your stomach.
Up to three-quarters of your stomach may be removed during a sleeve gastrectomy. The remaining portion is pulled up and stitched. This creates a smaller, longer stomach.
No matter what type of gastrectomy you undergo, the same thing happens after the procedure. You will be stitched up, bandaged, and brought to a hospital room to recover. Nurses will monitor your vital signs the whole time.
You can expect to stay in the hospital for one to two weeks after the surgery. During this period, you’ll likely have a tube running from your nose to your stomach. This allows doctors to remove any stomach contents. It helps keep you from feeling nauseated.
You will be fed through a tube in your vein until you are ready to eat and drink normally.
Tell your doctor immediately, if you have any adverse symptoms or pain that is not controlled with medication.
Once you go home, you may have to adjust your eating habits. Some changes may include:
You may also need regular injections of vitamin B-12.
