Gastric Band Surgery in London


Gastric band surgery is one of the bariatric procedures that can help with weight loss. An adjustable band is fitted around your stomach during the operation. It reduces the size of your stomach in order to reduce the amount you can eat at each meal. The procedure is performed laparoscopically. It is usually completed in 30 minutes to one hour, and you will be given general anaesthetic during the procedure.

After gastric band surgery, most patients will be able to lose about half of their unwanted weight. The gastric band should help by restricting the amount you can eat at each meal, but in order to lose weight you will have to eat a carefully designed diet.

  • What risks are there for gastric band surgery?

    Gastric band surgery is a relatively common and safe procedure. However, there are some potential side-effects and other risks that you should think about before deciding to have the operation. Your doctor will go through these with you in detail.

    Side-effects:

    Some side effects are common after gastric band surgery. Many patients will feel some pain around the surgical incision, and you may experience a bit of bruising or swelling. Side-effects like this are usually quite mild and they don't last long.

    Complications:

    Problems can sometimes arise during the surgery or during your recovery. Although serious complications are rare, it is important to be aware of what can go wrong before you go ahead with the gastric band surgery.

    The gastric band procedure is a serious operation that requires general anaesthesia. There is a risk of surgical complications such as an allergic reaction caused by the anaesthetic, heavy bleeding, or problems caused by blood clots that could block veins in your leg or lungs.

    Complications specific to a gastric band operation are as follows:

    • Infection – you could develop an infection after the surgery even though you will be given antibiotics to try to prevent this. If an infection doesn't respond to antibiotics your band may need to be removed.

    • Damage to other parts of your abdomen – if any organs are damaged during the procedure, you might need more surgery to fix them.

    • Band problems - your band may slip out of place, leak, or work its way through the stomach wall. If this happens, your band may need to be repositioned, removed or replaced.

    • Gallstones – losing weight quickly can put you at risk of gallstones. Very large or painful gallstones might need to be treated surgically.

    • Failing to lose enough weight – some people still struggle to lose weight after getting a gastric band. There is also a risk of regaining the weight if you aren't careful about your diet and lifestyle.

    Although a gastric band can usually be fitted laparoscopically, there is small risk that your doctor will need to change approach during the procedure. Sometimes a larger incision needs to be made in order to deal with complications or to finish the procedure safely.

    The risks of gastric band surgery are different for different people. Your doctor will help you to understand your personal risks. In general, you have a chance of about 5-10% of experiencing some kind of side effect after the procedure. About 10% of patients require further surgery or treatment after having a gastric band fitted. There is also a very small risk of serious complications, which can be fatal for about 1 in 2000 patients.

  • What alternative options are available?

    Most people should only consider weight loss surgery after trying diet and exercise first. Medication is also available that can help you to lose weight without having surgery. There are also some alternative bariatric procedures, the sleeve gastrectomy and gastric bypass.

  • What advantages are there for a gastric band?

    - Less invasive than other bariatric procedures

    - Reversible procedure.

    - Adjustable treatment customised to patient.

    - Shorter stay in hospital and shorter recovery time as compared to other bariatric procedures.

  • Is gastric band surgery the best procedure for you?

    Your bariatric surgeon can advise you on your eligibility for weight loss surgery and explain the different procedures that are available. You will be able to discuss the advantages and disadvantages of each option. You should ensure that you understand what will happen during the operation and as you recover. It is also important to consider whether gastric band surgery will meet your needs. The gastric band procedure is the least invasive operation for weight loss, so it could be a good choice if you want to avoid more extensive surgery. However, it is a serious operation that involves some risks. You should also think about how much weight you want to lose. A gastric band can enable you to lose a substantial amount of weight, but other weight loss procedures can have greater effects. Like other weight loss surgeries, the gastric band works by reducing the amount of food that fits into your stomach. It will therefore assist with dieting by ensuring that you feel full at the end of your meals. However, the gastric band is unique because its effects can be adjusted as your needs change. The adjustments will require extra follow up visits to the clinic, but they could help you to stick to your meal plan. The amount of restriction can be increased if you aren’t feeling full enough at the end of your meals or if you aren’t losing enough weight after the surgery. This makes the gastric band a good choice if you want more flexibility.

  • How long will recovery take?

    Provided you are well enough, you may be able to go home the same day of your operation. Otherwise, you will be required to stay overnight in hospital. A complete recovery from gastric band surgery can take one to two weeks.

  • Is gastric band surgery reversible?

    Gastric band surgery is reversible. The usual plan is for the gastric band to stay in place permanently so that you are more likely to lose weight and maintain any weight loss. However, the band can be removed at any time, but if you do have it removed, you are likely to regain weight. If the band needs to come out for any reason, this can be done using keyhole (laparoscopic) surgery, but might require open surgery.
