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.

The two types of procedures are restrictive surgeries. This means that they reduce the size of the stomach which effectively reduces the amount of food that it can hold. Persons who have had the procedures begin to have early satiety which reduces their food intake. Over time, they begin to lose weight since most of the food that is eaten is used to provide energy and very little, if any, is stored as fat.

As the name suggests, gastric banding involves the use of an elastic band made of silicone. This band is slipped onto the upper portion of the stomach using a laparoscopic approach. In laparascopic surgeries, procedures are conducted through small incisions made in the abdomen as opposed to open procedures where one large incision is needed. The squeeze that is provided by the band on converts the stomach into a small pouch.

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.

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.

The two bariatric operations are usually done as day cases. You can home on the same day that you are operated. One can resume their daily routine within 24 to 48 hours. The general advice is that one remains on light diet consisting of mashed up foods and liquids for at least two weeks. Soft foods and the regular diet follow thereafter.
