Laparoscopic adjustable gastric band has consistently been shown to be a safe and effective treatment for morbid obesity, especially in Europe and Australia.
Data from the U.S.A regarding the LAGB has been insufficient.
Dr Parikh and colleagues from New York noted their experience with 749 primary laparoscopic adjustable gastric band over a 3-year period in a university teaching hospital.
The research team collected all data prospectively and entered it into an electronic registry.
Characteristics evaluated for this study included preoperative age, body mass index, gender, race, conversion rate, operative time, and hospital stay.
| Postoperative complications occurred in 13% of patients|
Percent excess weight loss, and postoperative complications were also assessed.
The researchers also performed annual esophagrams.
The team included 749 patients, of which 531 were females and 218 were males, undergoing
laparoscopic adjustable gastric band for treating morbid obesity, from 2001 to 2004.
The patients consisted of 630 Caucasians, 61 African-Americans, and 49 Latin Americans, with a mean age of 42 years, and a mean body mass index of 46.
The researchers noted that the median operative time and hospital stay were 60 minutes and 23 hours, respectively.
The mean percentage excess weight loss at 1 year, 2 years, and 3 years was 44, 52, and 52, respectively.
The researchers observed no mortalities.
Postoperative complications occurred in 13% of patients.
About 2% of patients had acute postoperative band obstruction, 1% had wound infection, 3% gastric prolapse, and 2% had concentric pouch dilatation.
The team noted that a further 1% had aspiration pneumonia, 2% had port/tubing problems, 0.3% severe esophageal dilatation/dysmotility, and 2% had overall band removal.
Dr Parikh's team concluded, “These American results substantiate the data from abroad that
laparoscopic adjustable gastric band is a safe and effective treatment for morbid obesity.
