Laparoscopic adjustable gastric banding using the LAP-BAND system demonstrates significant weight loss in US patients. This safe and effective bariatric surgery option shows results comparable to international data.

Area of Science:

  • Bariatric surgery
  • Medical devices
  • Obesity treatment

Background:

  • Laparoscopic adjustable gastric banding is a common bariatric procedure globally.
  • US Food and Drug Administration (FDA) trials showed varied results for the LAP-BAND system.
  • This study reviews US clinical experience beyond initial FDA trials.

Purpose of the Study:

  • To evaluate the safety and efficacy of the LAP-BAND system in a US patient cohort.
  • To compare US clinical outcomes with international data for laparoscopic adjustable gastric banding.
  • To assess the long-term effectiveness of the LAP-BAND system in treating morbid obesity.

Main Methods:

  • Retrospective analysis of prospective data from 500+ LAP-BAND procedures at 4 US centers.
  • Focus on 115 patients with at least 9 months follow-up and 43 with at least 12 months follow-up.

  • Data collection included weight loss, body mass index changes, and complication rates.

    • Main Results:

    • Average excess weight loss of 35.6% at 9 months and 41.6% at 12 months.
    • Body mass index decreased from an average of 47.5 to 38.8 (9 months) and 37.3 (12 months).
    • Low mortality (no deaths); 13% complication rate requiring operative management, with port displacement/tubing breaks being most common (7%).

    Conclusions:

    • The LAP-BAND system is a safe and effective treatment for morbid obesity in the US.
    • US clinical outcomes are comparable to international data.
    • Proper surgical technique, frequent adjustments, and comprehensive bariatric programs enhance LAP-BAND effectiveness.
