Bariatric surgeries are increasingly becoming an acceptable method of weight control in New York. In general these methods achieve their effect by reducing the stomach capacity which in turn reduces the amount of food that an individual can eat at a given time. Related to the same is early satiety and reduced absorption of nutrients. There are three main types of bariatric operations that are performed. These include gastric bypass, gastric banding and sleeve gastrectomy.
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.
There are two main forms of surgical approaches that can be used in the placement of silicone bands. The first, the open technique, is performed through a large incision in the anterior abdominal wall. Under direct visualization, the surgeon locates the stomach and places the band in the desired region manually. The second method which is the commoner and more preferred of the two is the laparoscopic approach. Here access to the abdominal cavity is through very small incisions.
The compression force that is used will vary from one individual to another. The most important determinant is the weight of the individual. Obese individuals will get a higher compression force than those that are classified as overweight. A tube connected to the silicone band can be accessed from an area under the skin. Fluid can be injected or withdrawn from this tubing so as to either increase or reduce the magnitude of compression.
There are several complications that may occur when one undergoes this kind of operation. They include, among others, excessive loss of blood, infections, vomiting and nausea. Excessive compression is thought to be the main contributing factor for nausea and vomiting. Reducing the compression force reduces the severity of these two. To reduce the risk of infections, prophylactic antibiotics have to be administered.
Gastrectomy can also be performed through an open and laparoscopic techniques. The laparoscopic option is the more preferred option due to the lower rate of complications. During gastrectomy, the stomach is cut along its length and a large portion of it (between 75% and 80%). The remnant is a small tubular structure that also resembles a sleeve and hence the name.
When the stomach is converted into the tubular structure, the period of time that food takes in the organ is considerably reduced. This is a desired effect of the operation. Side effects that arise from the performance of sleeve gastrectomy are almost the same as those that are realized with the banding technique. Those that may be specific to gastrectomy include leakage of food through incisions on the stomach and displacement of staples or stitches.
Ideal candidates to undergo bariatric surgeries are persons that have tried losing weight through lifestyle modification and have been unsuccessful. Regular exercise and proper diet are among the most effective modalities of weight loss and their benefits must be optimized first before other solutions are considered. A patient with a very high body mass index stands to benefit more than one with a lower value.
