Laparoscopic Gastric Bypass


This is a major surgical procedure performed under general anaesthesia. It is usually performed in patients with a BMI between  40 and 50. The procedure Reux-en-Y bypass is more extensive and complex compared to the sleeve gastrectomy. It involves the division of the stomach leaving a small pouch at the top connected to the food pipe (oesophagus). The flow of food is then re-routed by joining this pouch to downstream small bowel by-passing the greater portion of the stomach and first parts of the small bowel. The small stomach pouch created means you can only eat a restricted amount of food, while bypassing part of the small bowel means that you do not absorb as many of the calories, vitamins or minerals in the food. Because of this you need to make sure you do not develop malnutrition.

Gastric bypass
The operation takes place through small incisions, 0.5-1cm typical size, through which gas is inflated in order to create space and make internal organs easy to see. A long thin tube with a tiny camera at the tip (laparoscope) is then inserted into the abdomen guiding the insertion of further long specialised laparoscopic instruments which are used to perform the procedure. The amount of weight you loose will also depend on the types of food you eat and the amount of exercise activity you undertake. If you continue eating bigger and bigger meals with time your stomach can stretch.

Benefits of gastric sleeve

You should expect to loose approximately 70% of your excess body weight over the first 2 years following surgery provided you are committed to a healthy diet and good exercise. If you suffer from type II diabetes, within a few days to weeks your body will be able to control sugar better and medication will no longer be necessary to control your diabetes.

Before the procedure

A low fat liquid diet is recommended prior to your surgery to shrink the liver In order to help with surgery. A change in lifestyle and increased exercise in preparation for life after the procedure are also expected.

Recovery

After the procedure you will be taken to the recovery room. Most patients need to spend two nights in hospital. You should be able to return back to normal activities and work after about 2 weeks. You will feel full quickly after eating therefore try to stick to small meals. You will need to employ a new balanced healthier diet with long-term vitamin and mineral supplements potentially with the help of a dietician, making the relevant lifestyle changes to reduce your calorie intake and increase your exercise. Be careful of not to eat small amounts of high calorie foods often as this will reduce your weight loss.

Risks of the operation

The risk of complications includes those relevant to any laparoscopic procedure such as infection, bleeding, blood clots, heart problems, pneumonia, urinary retention, development of a hernia, damage to organs inside the abdomen and anaesthetic risks.

Specific complication risks related to this procedure include the risk of the stomach leaking/bursting along the cut and stapled line (1%). This is potentially a major complication and may lead to further surgery in the future. There is a risk of developing ulcers along the stomach to bowel joint therefore you will need to undergo gastroscopies on occasions. There is also a rare risk of developing internal hernias and the risk of dumping syndrome. Dumping syndrome is a light-headed sensation that can happen in people eating high-sugar food. As the sugar is released quickly into the small bowel and absorbed it causes the release of high amounts of insulin.
