Laparoscopic gastric bypass is the gold standard operation for long-term weight control in the United States.
Laparoscopic adjustable silicone gastric banding is the preferred operative method for morbid obesity worldwide.
Limited data are available comparing the 2 procedure in the United States.
Dr Bessler and colleagues from New York prospectively collected data from 232 patients who underwent laparoscopic gastric bypass.
The investigative team also assessed 160 who underwent laparoscopic adjustable silicone gastric banding.
The team compared weight loss, complications, and early outcome of comorbidity resolution between the 2 techniques in the 392 patients between 2001 and 2004.
Differences in percentage excess weight lost at 3, 6, 12, 18, and 24 months postoperatively were evaluated.
The investigators evaluated improvement or resolution of comorbidities, and complications across procedure types.
|About 6% of laparoscopic gastric banding patients experienced complications|
The team found that the mean initial body mass index between groups was not significantly different.
There were significant differences in age, gender, and self-reported sweet-eating behavior between operative groups.
The investigators observed a greater percentage excess weight loss in patients who underwent gastric bypass than adjustable silicone gastric banding.
No significant differences in resolution or improvement of comorbidities between the groups were observed.
Among laparoscopic gastric banding patients, 6% experienced complications compared to 4% with laparoscopic adjustable silicone gastric banding.”
Dr Bessler's team concludes, “Early after surgery, laparoscopic gastric banding patients lose more weight than laparoscopic adjustable silicone gastric banding patients but have similar improvements in comorbidities.”
“Further follow-up is needed to determine the relative long-term efficacy of these procedures.”
