Important Facts On 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 usually connected to the skin using a small plastic tube. This helps the surgeon (and the patient) to exert some control over the band. By injecting or removing saline (or water) into this tube, the pressure that is exerted on the stomach can be increased or reduced as desired. An increase in the squeeze may be needed if the rate of weight loss is too slow. A reduction may be needed, on the other hand, if there are adverse side effects of the operation.

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.

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 is safe for use in children and adolescents. There are no adverse effects on growth for children aged less than fourteen years according to studies. The main side effects of this operation include leakage, aversion to food, vomiting, esophageal spasms and infections among others. With time, the stomach may dilate. This occurs over years and is rarely a cause for worry.

These two surgeries are performed as day cases. One can, therefore, be released to go home on the same day. Resumption of the normal daily routine can occur within a day or two. As for the diet, one needs to be on liquid diet and mashed foods for at least two weeks. The food to be eaten for the first two weeks should be either liquid diet or mashed foods.
