Stomach removal surgery
A gastrectomy is a medical procedurewhere all or part of the stomach is surgically removed.
There are four types of gastrectomy:
The stomach is connected to thegullet (oesophagus) at its top and the first sections of theduodenum (small intestine)at its bottom. Duringthe operation, the surgeon connects the oesophagus eitherto the small intestine or the remaining section ofstomach. This means that you'll still have a working digestive system,although it won't function as well as it did before.
You'll usually have to stay in hospital for one or two weeks after the procedure, where youmay receive nutritioninto avein until you can eat and drink again.
You'll eventually be able to digest most foods and liquids. However, you may need to make changes to your diet, such as eating frequent, smaller meals rather than three large meals a day. You may also need vitamin supplements to ensure you're getting the correct nutrition.
In many cases, a gastrectomy is an effective operation. Studies show thatsurvival rates for cancer after a gastrectomy are generally good. It's also been proven that people who have the operation to treat obesity lose a significant amount of weight afterwards.
However, many people who have a gastrectomy for stomach cancer live for much longer than five years without the cancer returning.
The survival rate of oesophagogastrectomy to treat cancer isn't as good. Studies have shown five-year disease-free survival rates of around 25% for this type of operation. This may be because this operation is usually done if the cancer is discovered at a late stage and has already started to spread.
Sleeve gastrectomy has a good success rate for treating obesity.
Studies have found excess weight loss of up to 75% after surgery. Excess weight loss is a measurement based on your weight before surgery and your ideal weight.
Further research is needed to determine how effective sleeve gastrectomy is for the long-term treatment of obesity. Studies often show that average excess weight declines over time, which suggests thatsome people regain some of the weight they initially lost.
To get the best results from a sleeve gastrectomy, it's important to follow the instructions given by your healthcare team about diet and exercise.
As with any type of surgery, a gastrectomy carries a risk of complications, such as infection, bleeding and leaking from the area that's been stitched together.
A gastrectomymay alsolead toproblems caused by a reduction in your ability to absorb vitamins, such as anaemia and osteoporosis .
A gastrectomy is a medical procedure that involves surgically removing all or part of the stomach.
A gastrectomy can be used to treat a variety of conditions, including obesity and some types of cancer.
There are different types of gastrectomy, depending on which part of your stomach needs to be removed.
