Lifestyle changes are highly recommend as ways of losing weight and remaining healthy. Unfortunately, these two are not effective in everyone and there is often a need for other options. Surgical weight loss procedures such as gastric banding and sleeve gastrectomy have increased in popularity in New York in recent years due to their effectiveness and safety profile. The two are types 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.
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.
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 (or gastric sleeve) refers to the surgical removal of a part of the stomach. This may be as much as 80%. The remaining stomach is a tubular pouch which closely resembles a banana. This method helps reduce weight in two ways: reduced capacity of the stomach and faster movement of food (hence less absorption). The shape is also believed to influence gastric hormone production such that one feels less hungry.
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.
