Weight Loss Surgery

About Weight Loss Surgery
 
There are a number of different procedures and operations available for anyone contemplating weight loss surgery. Which procedure to go for is often a very personal decision, dependant upon the desired weight loss, any other medical conditions such as diabetes, heartburn or sleep apnoea, and whether the individual wants a permanent or reversible treatment.  I undertake all weight loss procedures minimally invasively, either by laparoscopic surgery or endoscopy. 
Successful weight loss following surgery is dependant upon decreasing the amount of calories consumed. 
 
With all individuals thinking of having weightloss surgery I would encourage you to join a support group to hear about the experiences both before and after surgery of others and to inform you whether it is the right decision for you.
 
 
 
 
 
 

 

Gastric Bypass
Roux en y
 

​Laparoscopic gastric bypass is one of the most popular weight loss operation in Europe. It is particularly effective in patients with type II diabetes and usually causes a dramatic improvement in diabetes as well as weight loss. The operation consists of forming a small (20cc) stomach using surgical staples and joining this directly to the small intestine. The remainder of the stomach and duodenum are "bypassed" by the food consumed.

 

The operation usually results in three main effects; the small stomach limits what can be eaten at each meal, the bypassed duodenum causes appetite to be altered and has a beneficial effect on type II diabetes and joining the stomach directly to the small intestine, reduces the bowel available for absorbtion of nutirents.

 

The overall resulting effect is significant weight loss in most people, and improvement in diabetes where it is present.

 

Laparascopic
Gastric Band

 

Performed laparoscopically it involves placing a silicon band around the upper part of the stomach. The band has a fluid filled circular balloon inside it which allows the band tightness around the stomach to be adjusted as neccesary.

 

This limits the amount of food which can be consumed, helping you to maintain a healthier diet than before surgery.  It is completely reversible, should removal be required, it leaves the stomach as it was before the surgery. Most patients go home on the same day or day after the surgery and the band is tightened for the first time after six weeks to increase the weight loss effect 

 

Revision weight Loss Surgery

 

 

For those who have had weight loss operations in the past which are no-longer giving the desired effect or weight loss, revision surgery may be an option.  This is  done laparoscopically and can be particularly useful where a gastric band has slipped or is no longer maintaining a healthy weight. Gastric band removal, followed by conversion to either sleeve gastrectomy or gastric bypass can be undertaken.  

 

Older weight loss operations such as VBG (Vertical banded gastroplasty), may be converted to a sleeve gastrectomy or gastric bypass and a sleeve gastrectomy itself can be converted to gastric bypass or duodenal switch.

Revision weight loss surgery is more complex than primary weight loss surgery, with operations often taking longer to perform.  In addition, the results of revision surgery are not as predictable as primary surgery.

Sleeve Gastrectomy

 

 

 

​Sleeve gastrectomy is a laparoscopic operation in which the overall size of the stomach is reduced using staples, so that following surgery, the amount of food which can be consumed at each meal is reduced. This encourages a healthier diet which helps weight loss to occur.

 

Gastric Balloons

 

 

 

Particularly for those with a BMI under 35, who are not eligable to undergo weight loss surgery, I undertake two types of intra-gastric balloons; the Orbera balloon and the Obalon balloon. Both of these work by reducing the space available within the stomach, with the aim of reducing meal sizes.

 

The fluid-filled Orbera balloon is inserted with an endoscopy and may then remain in place for 6 months, before being removed in the same way. Up to 3 Nitrogen-filled Obalon balloons are swallowed in capsule form and inflated using an xray and may then remain in the stomach for up to three months, at which time they are removed with an endoscopy.

 

Weightloss surgery is carried out at either The Cobham Clinic, the private wing at The Luton & Dunstable Hospital or Spire Bushey, near Watford.
