Laparoscopic adjustable gastric banding (LAGB) is a surgical procedure that involves the placement of an adjustable belt around the upper portion of the stomach using a laparascope. The band is made of silicone and can be tightened by adding saline to fill the band (like blowing air into a doughnut-shaped balloon). The band is connected to a port that is placed under the skin of the abdomen. This port is used to introduce or remove saline into the band.
LAGB ultimately restricts the size of the stomach and the amount of food it can hold. It also slows the passage of food to the intestine. By doing so, signals to the brain from the gut allow for a sensation of fullness and satiety with the consumption of less food. This signal is sent from a small pouch created by the band in the upper stomach. When the pouch fills, the same signal is sent to the brain that occurred previously when the entire stomach filled.
Recovery varies with each individual. However, in general, LAGB offers a shorter hospitalization and quicker recovery . In general, most people can return to work 1 week after surgery (if their job is not too physically demanding). Normal activity can usually resume after 6 weeks.
A research team led by the London School of Hygiene and Tropical Medicine examined 3,882 records of patients who had undergone weight-loss surgery and a similar group of people who had not undergone the procedure and followed them for up to around 4 years.
They found that weight loss surgery patients underwent rapid weight loss for the first 4 months after surgery at a rate of almost 5 kilos a month. Weight continued to fall off, albeit at a slower rate, up to the end of year 4.
The researchers found that gastric bypass and sleeve gastrectomy were more successful procedures for achieving weight loss than other types of procedure. The estimated average 4 year weight loss was 83.8 lb (38 kg) for gastric bypass, 68.3 lb (31 kg) for sleeve gastrectomy and 44 lb (20 kg) for gastric banding.
Gastric bypass surgery is one of several weight-loss surgeries currently performed.The procedure in use today is called the Roux-en-Y gastric bypass.Diet recommendations after gastric bypass surgery vary depending on where the surgery is performed and your individual situation.Protein may be the most important of these foods early after surgery.Your body needs protein to build muscles and other body tissues, and to heal well after surgery.
Low-fat protein choices include:
- Skinless chicken
- Lean beef or pork
- Whole eggs or egg whites
- Dairy products
After gastric bypass surgery, your body will not absorb some important vitamins and minerals.You will need to take these vitamins and minerals for the rest of your life:Multivitamin with iron,Vitamin B12,Calcium
The ethos of laparoscopic surgery is to undertake the same operation through laparoscopic ports or ‘key holes’ rather than through a conventional big incision. This translates to lesser pain and early recovery while achieving the same results.The laparoscope has been one of the key advances in surgery, making much of minimally invasive surgery today possible.A laparoscope is a thin, fiber-optic tube that has a tiny video camera at its tip. The laparoscope is inserted through a small incision, generally but not always, in the navel, and guided to the problem area. The surgeon then inserts tiny surgical instruments through other small incisions to perform a procedure.The major benefit of laparoscopic surgery is that it only requires a few small incisions. This means less pain and external scarring and healing may be faster than traditional, open surgery.
Weight loss surgery has been shown to be the most effective and durable treatment for obesity.Patients may lose as much as 60 percent of excess weight six months after surgery, and 77 percent of excess weight as early as 12 months after surgery. And on average, five years after surgery, patients maintain more than 50 percent of their excess weight loss.In addition to its many health benefits, bariatric surgery can help to improve patient’s overall mood and psychological health.Obesity-related complications are generally related to weight therefore the surgically induced weight loss can be associated with improvement in these obesity-related complications.In fact, as little as three percent weight loss with lifestyle changes can be associated with a reduction in risk for metabolic and cardiovascular disease,compared with bariatric surgery weight loss figures well over 30 percent.weight loss surgery helps to improve many obesity related health conditions,including:
- High blood pressure
- High cholesterol
- Sleep apnea
