Expertise and safety that not all private patient units can offer

The Luton & Dunstable Hospital NHS Foundation Trust has been an NHS accredited weight loss surgery centre for the south of England since 2001. Our multi-disciplinary team of staff include 4 surgeons who between them carry out around 400 weight loss surgery procedures in a year.

Therefore, it is a natural progression to offer the service to our private patients, knowing that they are going to receive the expertise and safety that not all private patient units can offer.

We currently offer 3 procedures, Laparoscopic Gastric Band, Laparoscopic Sleeve Gastrectomy and Laparoscopic Gastric Bypass.

Our patients are fully assessed by a multidisciplinary team prior to surgery to ensure that an operation will be safe, appropriate and will fulfil the needs and expectations of each individual patient. You will have the opportunity to discuss surgery, the risks and benefits as well as the long-term implications and responsibilities of the different procedures.

  • The Laparoscopic Gastric Band is an adjustable silicone band placed around the top of the stomach, just below the oesophagus (food pipe). The band creates a re
    striction or narrowing to the top of the stomach, forming a smaller stomach or “pouch” about the size of a golf ball. This serves to reduce the size of the stomach and the amount of food that can be ingested in any one meal, as well as slowing the passage of food through the restriction.

    The band is connected via narrow tubing to a port, which is placed under the skin either to the left side of the abdomen, or over the sternum (chest bone). The band can be adjusted post-operatively by injecting fluid into the port, to inflate the band (rather like the inner tube of a tyre) and creates a further restriction to the passage of food to reduce food intake and encourage further weight loss.

    The Operation is performed laparoscopically using keyhole surgery under general anaesthetic. Five small incisions are made into the abdomen into which a flexible camera scope and surgical instruments can be introduced, enabling the surgeon to manoeuvre the band into place from the back of the stomach, securing it with sutures such that it remains in place. This technique avoids the necessity for a large abdominal incision and aids a quicker recovery time for patients.

    LAGB avoids large incisions and unlike other forms of weight loss surgery, the operation does not permanently alter or change the anatomy of the gut and intestine. As
    the procedure is carried out laparoscopically, post-operative recovery times are fast and most patients can expect to be discharged home after 1 day post operatively.

    Weight loss tends to be more rapid in the first year post-banding with maximal weight reduction achieved at 18 months – 2 years. Patients can achieve up to 50% excess body weight loss or 30% of initial weight. This weight loss will reduce the risk of disease associated with obesity and improve quality of life for very many patients. Your long term weight loss success can only be achieved by making permanent dietary and lifestyle changes in addition to the band restriction. Having a lap band in place will not effortlessly make you lose weight.

    The band is adjustable to suit the individual patient. The band is intended to remain in place permanently to help achieve and maintain weight loss. It can be removed if necessary, but this requires further surgery. Gastric banding does not in interfere with other types of surgery, but your doctor should be informed that you have a band in place.

  • Sleeve Gastrectomy uses a restrictive technique to encourage weight loss. The stomach is divided vertically from top to bottom, and the larger stomach section is then removed. This leaves a smaller stomach pouch which is around 25-30% the size of your original stomach.

    The sleeve Gastrectomy encourages work loss by reducing the volume of food you can eat. Your stomach will be around 70% smaller than before the surgery, meaning that the portion sizes that you are able to manage will be reduced. The sleeve Gastrectomy works on the basis of being a restrictive procedure only and there is no element of malabsorption associated with this type of surgery. A sleeve Gastrectomy is permanent and the alteration to you stomach is not reversible.

    After surgery it remains very important that you follow a sensible, low calorie diet to assist with your weight loss. Whilst the surgery will help you to control the amount of food you eat, the type of food that you eat will remain your own personal choice!

    The operation is performed laparoscopically using keyhole surgery under general anaesthetic. Five small incisions are made into the abdomen into which a flexible camera scope and surgical instruments can be introduced. This technique avoids the necessity for a large abdominal incision and aids a quicker recovery time for patients.

    Unlike some other forms of bariatric surgery, a laparoscopic sleeve Gastrectomy does not affect the valves or nerves in the stomach. This means that although the stomach is reduced, the stomach function remains intact. As the stomach continues to function as normal, there are generally fewer restrictions over the types of foods that can be managed following this type of surgery. As the procedure is carried out laparoscopically, post-operative recovery times are faster than with open bypass techniques and most patients can expect to be discharged home within 2-3 days post operatively.

    Rates of weight loss will vary between individuals and successful long term weight loss will only be achieved if permanent changes to the diet and level of physical activity are made, in addition to the effect of surgery. You should expect weight loss to be most rapid within the first 2 years after surgery. After 1 year you may expect to have around 45-50% of you excess body weight. This figure is based on early research and as mentioned results will vary between individuals.

  • Gastric bypass combines restrictive and Malabsorptive techniques to produce weight loss:

    Restrictive– the upper portion of the stomach is stapled to create a small ‘upper stomach’, or pouch about the size of a golf ball.

    Malabsorptive – the intestine is cut or divided. The lower portion of this division (the long roux limb) is then lifted and joined to the new stomach pouch. The free end of the intestine (the biliopancreatic limb) is then joined to the remaining portion of the gut forming a ‘Y’ shape.

    Food eaten passes into the pouch, which becomes full with only very small quantities of food, resulting in the feeling of fullness or satiety. Food then bypasses the remainder of the stomach and passes through the newly created opening into the long roux limb. This ‘replumbing’ of the intestine results in the partial malabsorption of food and calories, aiding further weight loss. Because gastric bypass surgery alters the anatomy of the gut and digestive process it is not reversible.

    The operation is performed laparoscopically using keyhole surgery under general anaesthetic. Five or six small incisions are made in to the abdomen into which a flexible camera scope and surgical instruments can be introduced. This technique avoids the necessity for a large abdominal incision and aids a quicker recovery time.

    Laparoscopic gastric bypass combines both restrictive and malabsorption and may be suited and may be better suited to patients with more complex eating patterns. Bypass has demonstrated good long-term weight loss maintenance results for patients. As the procedure is carried out laparoscopically, post-operative recovery times are faster than with open bypass techniques and most patients can expect to be discharged home 2 days post-operatively.

    Weight loss tends to me most rapid in the first year post-bypass, with maximal weight reduction achieved at 18 months-2years. The rate of weight loss may vary, but an initial loss of 1-2kg per week is to be expected. At 2 years, patients can achieve up to 70% excess body weight loss, or 50% of initial weight. This weight loss will reduce the risk of disease associated with obesity and improve quality of life for very many patients. Your long term weight loss success can only be achieved by making permanent dietary and lifestyle changes in addition to the effect of the surgery.
