Laparoscopic Gastric Bypass Versus Laparoscopic Adjustable Gastric
Banding: Indications for and results of laparoscopic adjustable gastric banding (LAGB) and laparoscopic gastric bypass (LGB) are still controversial, especially between Europe and the United States. The recent availability of gastric bandings in the United States made it necessary to compare the two techniques. Method We compared a series of 456 laparoscopic gastric bypass to a series of 805 laparoscopic adjustable gastric banding performed in two different institutions. Body mass index (BMI), complication rate, mortality, and excess weight loss (EWL) after 3, 6, 12, and 18 months were obtained. A Fischer's exact test and a Student t test with covariance analysis were used for statistical analysis. Results Results are expressed as a mean +/- standard deviation, comparing laparoscopic gastric bypass with laparoscopic adjustable gastric banding. Preoperative BMI was 49.4 +/- 8.3 kg/m(2) versus 42.2 +/- 4.9 kg/m(2), respectively. Perioperative major complication rates were 2.0% versus 1.3% (NS), and the early postoperative major complication rates were 4.2% versus 1.7%, respectively. Mortality rate was 0.4% versus 0% (NS), respectively. The global EWL was 36.3% for laparoscopic gastric bypass versus 14.7% for laparoscopic adjustable gastric banding at 3 months , 51.6% versus 21.9% at 6 months, 67.0% versus 33.3% at 12 months, and 74.6% versus 40.4% at 18 months, respectively. Longterm followup for the laparoscopic adjustable gastric bandinggroup showed an EWL of 47% at 2 years, 56% at 3 years, and 58% at 4 years.Patients were sorted after their preoperative BMI. The EWL at 3, 6, 12, and 18 months was statistically superior in the laparoscopic gastric bypass group, for any BMI ranges. Conclusion These data suggest that laparoscopic gastric bypass provides a higher EWL at 18 months, compared with laparoscopic adjustable gastric banding, and this was true for any preoperative BMI range. It is associated with a higher early postoperative complication rate. Source: Laparoscopic Gastric Bypass Surgery to Reduce Obesity |
