Sleeve gastrectomy or gastric sleeve surgery is a type of weight-loss surgery where the size of your stomach is reduced by removing the lateral 2/3rds of the stomach (approx. 75-85%) with a stapling device, shaping the remaining stomach into a tube or ‘sleeve’ so that you can only eat small meals.The gastric sleeve procedure takes one to two hours. The surgeon will usually be able to work laparoscopically, which means that you will only need small, keyhole incisions. You will need to have a general anaesthetic.
On average, a person will lose 50-60 % of their excess body weight (the difference between their weight before the operation and their healthy weight) within a year with gastric sleeve surgery. However, the surgery won’t do all of the hard work for you. Although having gastric sleeve surgery should make sticking to your diet a little easier, you will still need to follow your diet plan very carefully.

Gastric sleeve surgery is generally safe, but there are always risks when you are having an operation. You will need to discuss these risks with your doctor before deciding if the procedure is right for you.
Certain side effects can happen after gastric sleeve surgery. Side effects will usually only be temporary and they are generally mild. The most frequent effects are soreness or some slight swelling round the incisions. Some people experience discomfort after eating in the first days after the operation. This feeling should go away once you heal, as long as you don't overeat.
More serious complications can also happen when you have gastric sleeve surgery. This is when problems occur during or after the operation. Such problems are much less common than the milder side effects. Most people will not experience any serious complications from this surgery.
One potential risk of having the procedure is that you will need to be put under a general anaesthetic. Some people can have a bad reaction to the anaesthetic. Other potential complications associated with surgery include heavy bleeding and blood clots. The chance of surgical complications is low, but they are increased by conditions such as high blood pressure.
Infection – although antibiotics can help prevent post-surgical infections, there is still a chance that you will develop one and require further treatment
Damage to your organs – although the risk is low with an experienced surgeon, it is possible other organs in your abdomen could be damaged. Another procedure could be required to set it right.
Staple line leak – during a sleeve gastrectomy, your stomach will be sealed with surgical staples. If these start to leak while you are recovering from surgery, you may need another operation to seal your stomach.
Sleeve stricture – sometimes the sleeve-shaped stomach can get narrower after surgery or an ulcer may form in it. More surgery or a procedure called an endoscopy might be necessary to fix the problem.
Gallstones – some people get gallstones when they lose a lot of weight quickly.
Failure to achieve weight loss – a sleeve gastrectomy will help you to lose weight, but it doesn't guarantee you'll reach your goal. Some people don't manage to get rid of their excess weight even after surgery.
There is a chance your surgeon may need to convert your keyhole procedure to open surgery. This means making a bigger cut on your abdomen. This is only done if it's impossible to complete the operation safely using the keyhole technique.
The chance of complications during or after the procedure will vary between individuals. Your surgeon will be able to provide personalised advice on the risks of weight loss surgery. In general, about 5% of people will experience some complications when having a sleeve gastrectomy. The chance of experiencing fatal complications during surgery is 0.2%.
Surgery should only be used for weight loss after you have tried losing weight by dieting and exercising. Your doctor might also recommend trying certain medicines before considering surgery. If you are sure about bariatric surgery, you have a few alternative procedures to consider. In addition to sleeve gastrectomy, it is possible to have a stomach band fitted or to undergo a gastric bypass operation.
- During the laparoscopic sleeve gastrectomy the nerves of the stomach and pylorus are not altered, preserving the function of the stomach.
- The rest of the gastrointestinal tract anatomy is not altered, so the food ingested follows the normal course. This results in less chance of developing lack of vitamins and minerals and dumping syndrome.
- The procedure decreases significantly the hunger by removing the part of the stomach that produces the main stimulating hormones.
- Fewer clinic follow-ups than the laparoscopic stomach band, since there is no need for band size adjustments.
If you are thinking about having gastric sleeve surgery, it is important to understand what the procedure involves, what to expect during recovery, and what the risks are. Your doctor can help you to compare the risks and benefits of different kinds of weight loss surgery, but it is still your decision. You need to be sure that having the operation will help you to lose weight. The gastric sleeve procedure could help if you struggle with hunger when you are dieting, as it can lower your appetite. It will also reduce the amount that you can fit in your stomach, so it will help you to feel full after smaller meals. If you think these effects will make it easier for you to lose weight, you are prepared to undergo the procedure, and you are committed to your diet plan, then this could be an effective weight loss surgery for you.
You will normally need to stay in hospital for about two to three days after the operation. Full recovery from a sleeve gastrectomy can take two to three weeks. You will need to be very careful about the kinds of food you eat during your recovery, but once your stomach has healed you will be able to eat a normal range of foods, in moderation.
Gastric sleeve surgery is considered to be a permanent weight-loss procedure. Part of your stomach will be permanently removed during the operation. However, there is a chance that the remaining section will stretch over time. If this happens, the amount you can eat will not be restricted any more and you may start to gain weight again. Sticking to your diet and continuing to eat well after you reach your target weight can help to prevent this from happening.
