Laparoscopic procedures have emerged over the past decade for treatment of obesity. Laparoscopic adjustable gastric banding is the easiest surgical technique for morbid obesity.
The authors analyzed the long term results of laparoscopic adjustable gastric banding in their center.
A total of 172 consecutive patients who had undergone laparoscopic adjustable gastric banding between May 2005 and February 2011 in authors clinic were contacted for evaluation. The main outcome measures were complications, secondary operations, percent excess weight loss, mortality, patient satisfaction and band removal rate.
The follow-up rate was 62.2%. Mean age of patients was 30.6 years. Mean body mass index of patients was 48.47 +/- 7.8 kg/m2. Median follow-up interval was 36 months (min 8, max 81) and band removal rate was 19.1%. There was one mortality. Of all patients, 33 had band removal. The band was removed laparoscopically in 21 patients. The main reason for band removal was slippage followed by band erosion. After band removal, 4 patients had re-banding, 5 had Roux-en-Y gastric bypass. Overall, the mean percent excess weight loss was 50.6 +/- 7.8% (range, 5-100%). Mean percent excess weight loss for those who had band removal was 27.8 +/- 5.78% (range 12.5-34.1%). Overall satisfaction index was rated as "good" for 42% of patients.
Despite a low satisfaction index, considerable mean percent excess weight loss and vast improvement in co-morbidities is achieved after laparoscopic adjustable gastric banding. The authors conclude that laparoscopic adjustable gastric banding can be utilized as the initial surgical procedure in morbid obesity.

    ABSTRACT: Weight loss outcomes following laparoscopic adjustable gastric banding (LAGB) are widely variable, and physical activity (PA) participation improves these results. The purpose of this study was to retrospectively describe PA behaviors before and after LAGB and to evaluate the impact of PA on weight loss outcomes. Participants were 172 individuals (145 females, mean age 43.3 ± 12.0 years, mean body mass index [BMI] 43.8 ± 5.1 kg/m(2)) who underwent LAGB at a university medical center. Height, weight, presence of comorbidities, and PA participation were assessed prior to and 3, 6, and 12 months after surgery. Those who reported engaging in ≥150 min of weekly moderate-to-vigorous PA (MVPA) were considered active. Less than 40 % of participants were active prior to surgery, while 31 % of those who were inactive before surgery became active at 6 months of follow-up. Unlike previous reports on gastric bypass patients, there was no statistically significant (p > 0.05) relationship between postoperative PA status and weight loss outcomes at 3, 6, or 12 months in LAGB patients. Interestingly, participants who reported ≥150 min of MVPA prior to surgery achieved approximately 10 % greater excess weight loss (p < 0.05) and a 2.4-kg/m(2) greater decrease in BMI (p < 0.05) at 1 year post-LAGB compared to those who were inactive preoperatively. In our sample, higher levels of preoperative PA participation were associated with improved weight loss outcomes following LAGB. We posit that higher preoperative volumes are indicative of habitual exercise and that those who report being active prior to surgery are likely to maintain these behaviors throughout follow-up.

    ABSTRACT: Laparoscopic adjustable gastric banding is considered the least invasive surgical option for the treatment of morbid obesity. Its initial popularity has been marred by recent long-term studies showing high complication rates. We sought to examine our experience with gastric banding and factors leading to reoperation. We reviewed retrospective data of 305 patients who underwent laparoscopic adjustable gastric banding between 2004 and 2011 at a single institution, 42 patients of whom required a reoperation, constituting 13.8%. Patients undergoing elective reoperations for port protrusion from weight loss as a purely cosmetic issue were excluded (n = 10). Patients' demographic data, weight loss, time to reoperation, and complications were analyzed. Of 305 patients, 42 (13.8%) required reoperations: 26 underwent band removal (8.5%) and 16 underwent port revision (5.2%). The mean weight and body mass index for all patients who underwent reoperations were 122.6 kg and 45.0 kg/m(2), respectively. The most common complication leading to band removal was gastric prolapse (n = 14, 4.6%). The most common indication for port revision was a nonfunctioning port (n = 10, 3.3%). Laparoscopic adjustable gastric banding was initially popularized as a minimally invasive gastric-restrictive procedure with low morbidity. Our study showed a 13.8% reoperation rate at 3 years' follow-up. Most early reoperations (<2 years) were performed for port revision, whereas later reoperations (>2 years) were likely to be performed for band removal. Laparoscopic adjustable gastric banding is associated with high reoperation rates; therefore bariatric surgeons should carefully consider other surgical weight-loss options tailored to the needs of the individual patient that may have lower complication and reoperation rates.
