Morbid obesity, which correlates with a material substance mass index (BMI) (weight [kilograms]/height [[meters]sup2]) of 40 or higher, is a chronic, intractable disease that, if left untreated, ends in increased morbidity and mortality and a decreased life span. (1) More than 97 million nation in the United States are either overweight or obese, (2) resulting in health care prices that approach $70 billion by means of year. (3) According to the Surgeon General's newly come "call to action," the number of populace who are overweight or obese have reached nationwide epidemic proportions. In 1999 an estimated 61% of adults in the United States were overweight, as were 13% of children and adolescents. (4) Traditional nonsurgical weight los regularitys that attempt to decrease weight by the agency of dietary and behavioral interventions frequently result in disappointing outcomes with a high rate of relapse. (5) Surgery to treat morbid obesity has been recognized through the National Institutes of Health (NIH) as an approach for well-informed and motivated patients for whom the surgical risks are acceptable. (6)

Until freshly surgical options were limited to processs performed through an open incision (Table 1) These performances permanently alter the anatomy of the digestive tract (Figure 1) on stapling or bypassing the stomach and a portion of the small intestine or a combination of these proceedings This can result in long-term morbidities, including macronutrient and micronutrient deficiencies and, in rare instances, death. (7) The sum of two units surgical weight loss procedures in the greatest degree commonly performed in the United States for morbid obesity have been the Roux-en-Y gastric bypass and vertical banded gastroplasty. (8)

The Roux-en-Y gastric bypass is one as well as the other restrictive (ie, limits the amount of solid nutriment the patient is able to ingest) and malabsorptive (ie, decreases intestinal absorption) (Figure 2) During this process staples are used to set up a small, restrictive upper gastric bag which then is anastomosed directly to the small bowel, bypassing in the greatest degree of the stomach and about of the small intestine. (9) Vertical banded gastroplasty is a restrictive step in which staples are used to make a small stomach pouch; however, no rerouting of the digestive tract happens (Figure 3). (10)

In June 2001 the US provisions and Drug Administration (FDA) approved an adjustable gastric banding rule for use in the surgical treatment of morbid obesity (Figure 4) This approval was received after clinical trials were leadershiped through-out the country between 1996 and 2001 consequence s of these studies, as well as those of other studies managemented throughout the world, have demonstrated the safety and efficacy of adjustable gastric banding. (11) The gastric band, which is adjustable and reversible if medically indicated, is placed laparoscopically and does not alter the normal anatomy. Since 1993 more than 80000 adjustable gastric banding steps have been performed worldwide. (12)

HISTORY OF GASTRIC BANDING

The universal of stomach banding to treat obesity originated in 1976 when Lawrence Wilkinson, MD used a strip of synthetic polypropylene entangle as the band, resulting in a reduction of the gastric reservoir. (13) Since that time, variations onward this procedure using synthetic polyethylene terephthalate and polytetrafluoroethylene vascular grafts have been performed. (14)

The first adjustable silicone gastric band was introduced in the 1980 on Lubomyr Kuzmak, MD, who added an inflatable portion to the band attached via a tube to an access port that was implanted subcutaneously. (15) This configuration allowed for postoperative adjustments of the size of the opening (ie, stoma) between the upper and lower stomach reservoirs by dint of the addition or removal of saline via a needle inserted into the access port. With the advancement of laparoscopic surgical techniques and a growing demand for an adjustable gastric band that could be inserted without the ne for make open surgery came the introduction of laparoscopic adjustable gastric banding. Today, the laparoscopic adjustable gastric banding theory includes a slip-through buckle with self-locking closure plan and a calibration tube to facilitate sizing of the sack at the time of placement.

RISKS AND BENEFITS

Morbid obesity is associated with serious medical question s such as type 2 diabetes, hypertension, heart disease, gastroesophageal ebb disease, sleep disorders, and asthma (Table 2) (16) Studies exhibit that even a moderate weight los after laparoscopic adjustable gastric banding surgery can originate in improvements in all of these conditions. (17) Numerous studies present to view that weight loss following laparoscopic adjustable gastric banding surgery significantly improves patients' quality of life physically, socially, and psychologically. (18) The risks of this surgery are outweighed through the benefits it provides.

Risks. Surgeon report fewer perioperative complications following laparoscopic gastric banding surgery than with other forms of surgery for obesity. (19) The principally commonly reported postoperative complication associated with laparoscopic gastric banding is stomach bag enlargement, which usually is associated with slippage of the stomach wall end the band. (20) The incidence of this complication, however, has been dramatically reduc with surgical technique modifications. individual researcher reported a reduction in stomach slippage from 30% in his first 50 patients to 25% in a later cluster of 200 patients. (21) There also have been repon of erosion of the band in consequence of the stomach tissue; a large European cogitation showed an erosion rate of 1% (22) Complications related to the access port and tubing also have been reported, including motion or tilting of the access port, leaking or defective tubing, or infection at the access port site. Better placement and fixation techniques have originateed in fewer of these complications. (23) Rarely, stomach perforation may offer during surgery. (24)
