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.

The results of this operation vary from one individual to another. The procedure is safe for the most part but there are some possible side effects that you need to be aware of. Those that are experienced commonly include vomiting, nausea, minor bleeding and wound infection. Small adjustments to the tightness of the band usually control the nausea and vomiting.

Sleeve gastrectomy involves the removal of a large part of the stomach to leave between 20 and 25% of the original. The resultant shape is tubular or sleeve-shaped (hence the name). Weight loss is mainly due to two effects. The first is the reduced volume which also reduces food intake and contributes to early satiety. The second is the increased transit time that reduces food absorption.

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.
