U.S. experience with 749 laparoscopic adjustable gastric bands: intermediate outcomes

Area of Science:

• Bariatric Surgery
• Minimally Invasive Procedures
• Obesity Treatment

Background:

• Laparoscopic adjustable gastric band (LAGB) is established as safe and effective for morbid obesity in Europe and Australia.
• U.S. data on LAGB effectiveness and safety has been limited.
• This study presents findings from a 3-year experience with 749 primary LAGB procedures at a U.S. academic hospital.

Purpose of the Study:

• To evaluate the safety and efficacy of Laparoscopic Adjustable Gastric Banding (LAGB) in a U.S. patient population.
• To analyze outcomes including weight loss, operative time, hospital stay, and postoperative complications.
• To provide U.S.-based data to support the use of LAGB for morbid obesity treatment.

Main Methods:

• Prospective data collection for 749 primary LAGB procedures over 3 years.
• Evaluation of preoperative demographics, operative details, and postoperative outcomes.
• Inclusion of complications, percent excess weight loss (%EWL), and annual esophagrams in the analysis.

Main Results:

• Mean %EWL reached 44.4% at 1 year, 51.8% at 2 years, and 52.0% at 3 years.
• Low conversion rate (0.1%) with median operative time of 60 minutes and hospital stay of 23 hours.
• Postoperative complications occurred in 12.8% of patients, with most being manageable and reversible; no mortalities reported.

Conclusions:

• The U.S. experience with LAGB aligns with international findings, confirming its safety and efficacy.
• LAGB is a viable and effective surgical option for treating morbid obesity in the United States.
• The study provides robust data supporting LAGB as a beneficial bariatric procedure.
