Bariatric surgery refers to an operation that is done with the objective of losing weight. Many different forms of this operation exist in New York but the principle under which they work is the same. These operations are done to reduce the volume of the stomach which effectively reduces the amount of food that can be consumed at a given point in time. Less nutrients are absorbed and over time, weight loss sets int. There are a few things regarding gastric banding and sleeve gastrectomy you should know.
Banding and gastrectomy are distinct options but the principles are the same. As the name suggests, banding involves the use of an artificial band made from silicone. This band is usually fixed to a portion of the stomach resulting in compression. The compression causes a reduction in the volume of the stomach which means that less food will be held from the time of the duration onward.
Gastric banding is the simpler of the two procedures. It involves the fixation of a special band (made of silicone) onto the external surface of the stomach resulting in compression. The external force reduces the size of the stomach and by extension, the food that one can eat at a given point in time. The reduced size of stomach also causes early satiety which reduces food intake even further.
The magnitude of compression varies from one patient to another depending on their condition. A higher degree of compression is likely to be used if the patient is obese with associated medical complications. A plastic tubing is usually connected to the tubing and one end can be accessed from an area under the skin. The tube allows for adjustments to compression force to be made. Injection of water in the tubing increases the compression and withdrawing reduces it.
There are a number of complications that may be encountered with this procedure. These include among others, injury to vital structures in the abdominal cavity, infections, bleeding, nausea and vomiting. Nausea and vomiting are often the result of too much compression. Withdrawing some water from the control tubing helps relieve the pressure which in turn reduces the likelihood of nausea and vomiting. Antibiotics have to be administered to reduce the risk of infections.
Gastrectomy can be conducted either laparoscopically or the open procedure. The laparoscopic option is by far, the more preferred due to the fewer complications. In performing gastrectomy, close to 80% of the stomach is removed and discarded. This makes the procedure irreversible unlike banding. The resultant organ looks like a sleeve and hence its name.
The tubular structure of the stomach after the operation reduces the transit time of food considerably. This means that less nutrients are absorbed and this is what all bariatric operations aim to achieve. Side effects that may arise from gastrectomy are similar to those that are seen with the banding procedure. Those that may relate to gastrectomy only include food leakage and the loss of stitches or staples.
An ideal candidate to undergo bariatric surgery is one who has attempted achieving their objective using conservative methods. Such include participation in regular physical exercise and diet modification in a manner that reduces carbohydrate and fat content. Persons that have a high body mass index BMI of say, 40, are more likely to benefit than those with a lower value of this index.
