Important Facts On Gastric Banding And Sleeve Gastrectomy

By Martha Foster


Lifestyle changes are one of the most effective approaches in achieving weight loss. While their effect can be clearly appreciated in a majority of New York residents over time, there is a smaller group of people in whom these lifestyle changes alone cannot achieve the desired results. These people form the bulk of potential candidates for surgical weight loss procedures which include gastric banding and sleeve gastrectomy. The two operations are examples of 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.

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.

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 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.
