Gastric banding is a type of weight loss surgery for patients who want to lose weight due to their personal or medical reasons. Gastric surgery is also known as laparoscopic adjustable gastric surgery. In this type of surgery, the surgeon uses laparoscopic technique which involves making small incisions in the abdominal region of the patient.
The cuts are made to place an adjustable silicone band around the upper part of the stomach. When squeezed by the silicon band, the stomach becomes a pouch with about an inch-wide outlet. After the banding process is done, the stomach can hold only up to an ounce of food. A plastic tube runs from the silicon band to the stomach just under the skin. Whenever required, saline can be injected into the body. It makes the band tighter by filling the band.
There are two types of gastric banding: Gastric sleeve surgery and Vertical Banded Gastroplasty. Gastric sleeve surgery is performed through a large incision in the abdomen using small instruments. Vertical banded gastroplasty involves a plastic band placed around the stomach. When compared to gastric sleeve surgery, vertical banded gastroplasty is less common.
Gastric banding leads to about 40-50% weight loss on a general basis. However, it solely depends on the type and nature of the patient. Gastric banding is considered to be a less invasive type of surgery and also one of the safest ways to lose weight for the patients. The procedure can be reversed if necessary, and in time the stomach normally returns to the same shape and size.
People tend to have a few problems while undergoing this surgery in some cases. The risk of death due to gastric banding is in the ratio of 1:3000. Some of the most common problems experienced by the patients during the treatment are nausea and vomiting. In rare cases, there might also be some minor surgical complications such as bleeding or wound infections.
