Gastric band surgery
Laparoscopic adjustable gastric banding surgery , commonly called a lap band is a silicone inflatable device that is placed around the upper stomach through laparoscopic gastric band surgery to treat obesity. The adjustable gastric band surgery is an most popular and common example of bariatric surgery designed for obese people with a body mass index (BMI) of 40 or more, or between 35 to 40 cases of patients with certain comorbidities that are known to improve weight loss, sleep apnea, diabetes, osteoarthritis, gastroesophageal reflux disease, hypertension (high blood pressure) or metabolic syndrome, among others.
How it works
According to the American Society for Metabolic and gastric surgery, obesity surgery is not an easy option for people suffering from obesity. This is a drastic step, and carries the usual pain and risks of any major surgery of gastrointestinal tract. However, the gastric band is less invasive surgery like that. Gastric band surgery is performed using laparoscopic surgery and usually results in a short hospitalization , fast recovery, small size scars and less pain than open surgical procedures. Because no portion of the stomach is stapled or removed and the patient's intestines are not redirected, and patient may continue to absorb nutrients from food normally. Gastric bands are made completely of biocompatible materials in order to be able to reside in the patient's body without causing any damage. So, not appropriate for all patients for laparoscopy. People who are extremely obese, with a history of previous surgery of abdomen or complicated medical problems can require an open approach.
It makes a small incision (less than 1 / 2 inch). Carbon dioxide (a gas that occurs naturally in the body) is inserted into the abdomen to create a work field for surgeons for procedure. Then a little laparoscopic camera is placed via the incision in the abdomen. The camera sends an image of the stomach and abdominal cavity to a video monitor. It gives the surgeon a good view of the key structures in the cavity of abdomen. Some other small incisions are made in the abdomen. The surgeon watches the video monitor and work via these small incisions by using instruments with long handles to complete the procedure. The surgeon creates a little tunnel which is circular behind the stomach, the gastric band is inserted through this little circular tunnel, and locks the band around the upper portion of stomach.
Clinical trials in laparoscopic (minimally invasive) patients undergoing gastric band surgery have said they felt better, patient spent more time doing leisure and some physical work , to benefit from improved productivity and economic opportunities, and had the more confidence than before the gastric band surgery .
The placement of the band creates a small pouch or stoma, in the upper stomach. This bag contains about half cup of food. (The stomach usually contains about 6 cups of food.) The pouch fills quickly with food, and the band slows the passage of food from the pouch to the lower stomach. In the upper portion of stomach registers as full, the message to the brain is that the whole stomach is full and this type of sensation helps the person to be hungry less often, feeling of fullness faster and longer period of time, eat in small amount and lose weight over time.

As people lose weight after gastric band surgery, these bands will need adjustments or fills to ensure comfort and its efficiency. The gastric band is adjusted by the introduction of saline into an access port that can be placed under the skin. A special needle is used to prevent damage to the lining of the port and avoid leakage.There are many different type of port designs ( e.g. high and low profile ), and can be placed in different positions according to surgeon preference, but are still attached (via sutures, staples, or some other methods ) with the muscles of abdominal wall in and around the diaphragm.
An adjustable gastric band can hold between 4 - 12 cc of saline, depending on its design. When the band is inflated through saline, pressure is applied around the outside of the stomach. This can reduces the size of the passage between the pouch created from the upper portion of stomach and lower portion of stomach and further limits the movement of food. During several visits to the doctor, the band is filled to the optimal restriction has been achieved - not so loose that hunger is not controlled, not tight that food can not move via the digestive system. The number of adjustments is an individual experience and can not be predicted with accuracy.
Weight loss after gastric band surgery results can vary from patient to patient and the amount of weight lose depends on several factors. The band is a limitation of the right and you must be committed to a new lifestyle and eating habits. Gastric band surgery is not a panacea, and the pounds will not be out alone. The weight loss per week is 1-3 pounds for the first year of operation is possible. Twelve months to eighteen months after the gastric band surgery, weekly weight loss is usually less. Remember that you always have to lose weight slowly and gradually. Losing weight too fast can cause more danger to health and can lead to many problems. The main objective is to achieve weight loss that can avoid by this, and can improves or resolves health problems which associated with severe obesity........ read more
