Abstract

BACKGROUND:

Recent studies document excess weight loss (EWL) of more than 50% with the laparoscopic adjustable gastric band (LGB). This study reviews the LGB experience at an urban academic center in terms of complications, reoperative rates, and comorbidities.

METHODS:

In this study, 144 consecutive patients undergoing LGB were prospectively reviewed. Data were collected including weight, body mass index (BMI), excess weight loss (EWL), comorbidities, and complications. Demographics were analyzed using a t-test. Linear regression was used to analyze the relationship of BMI, race, and age to EWL at 12 months.

RESULTS:

The study participants were 130 women with a mean age of 43 ± 11 years, a mean weight of 127.1 kg ± 20.5 kg, and a mean BMI of 45.6 ± 6.1. The mean follow-up period was 16 months. The mean EWL was 20% ± 14% at 6 months (n = 118), 26% ± 16% at 12 months (n = 106), 30% ± 20% at 18 months (n = 68), and 34% ± 23% at 24 months (n = 43). Patients with a BMI higher than 50 kg/m(2) had a lower EWL at 12 months than patients with a BMI lower than 50 kg/m(2) (P = 0.00005). The mean EWL at 12 months was significantly less for African Americans than for Caucasians (P = 0.0046; 95% confidence interval [CI] 3-15%). Patients older than 50 years had a lower EWL, but the difference was not statistically significant (P = 0.07). Complete and partial resolution of comorbidities occurred for 10% and 4% of the patients, respectively. Removal of the band with revision to a sleeve gastrectomy for inadequate EWL was required for 14 patients (11.5%). Complications occurred for 8% of the patients (n = 15) including port flipping, stoma obstruction, tube disconnection, port infections, dysphagia, and band slippage. Overall, 16.7% of the patients (n = 24) required reoperation.

CONCLUSION:

After LGB, a majority of the patients failed to achieve a 50% EWL, and 16.7% required reoperation. Laparoscopic adjustable gastric banding may not be the optimal bariatric procedure for patients older than 50 years, patients with a BMI higher than 50 kg/m(2), or African Americans.
