Basics Relating To Gastric Banding And Sleeve Gastrectomy

By Martha Foster


Having a balanced diet and engaging in physical activity regularly are two of the most well-known options of weight loss. While they may be effective in a majority of New York residents, there are cases where a more aggressive approach is needed. Surgical options such as gastric banding and sleeve gastrectomy are often considered as a last resort for such cases. They are types of what is referred to as bariatric surgery.

Bariatric surgeries are also known as restrictive surgeries. This is because they are designed to reduce the capacity of the stomach which effectively reduces the amount of food that is held at any given point in time. Since, the stomach fills a lot faster than before, there is early satiety and by extension, reduced food intake. The weight loss that is seen in subsequent weeks and months is mainly due to reduced food intake.

Gastric banding is achieved by use of a silicon band using laparascopic approach. When the band is slipped onto the upper part of the stomach (the fundus), it squeezes it to leave just a small outlet. The estimated capacity of this pouch is one ounce of food. Laparascopic procedures, use small entry points (ports) that result in smaller scars later on. This is in contrast to open surgeries in which large incisions have to be made.

The band is connected through a plastic tubing to an area just below the skin. The surgeon (or patient) can exert control on the pressure created by the band. When saline is injected through the tube, the pressure is increased which decreases the volume of the stomach further. This may be needed if the desired effects are not being seen. Drawing the saline achieves the reverse effect which is a reduction in the squeeze and an increase in the stomach volume.

Gastric banding has been shown to cause up to 50% in weight loss in a couple of months. The procedure is largely safe but a few side effects may be experienced. Such may include nausea and vomiting, wound infections or minor bleeding. Adjusting the tube often resolves the nausea and vomiting but removal of the tube may be needed if these effects are severe.

In sleeve gastrectomy, a large part of the stomach is removed with the remainder being between 20 and 25% of the original. The longitudinal resection (cutting) leaves a tubular structure which looks like a banana. The benefits of this operation are mainly twofold: reduced stomach capacity and increased transit time of consumed food. This means that food has less time to be absorbed.

Sleeve gastrectomy has been approved for use in children and adolescents. Studies show that it has no negative effects on the growth of children. Possible complications of this procedure include leakage of food, nausea, aversion to food, infections and esophageal spasms. Over time, the stomach may dilate but not significantly. It is important to remember that unlike the banding procedure, the sleeve procedure is irreversible.

The two procedures are considered day cases in most centers. What this means is that you can go home on the same day of the operation. One can resume their normal daily routine within a day or two. Usually, one has to be on a light diet comprising of liquids and mashed up foods of about two weeks. This is followed by soft foods for another two weeks then the regular diet.
