RT Journal A1 Kramer F, Stunkard AJ, Spiegel TA, et al T1 LImited weight losses with a gastric balloon JF Archives of Internal Medicine JO Archives of Internal Medicine YR 1989 FD February 1 VO 149 IS 2 SP 411 OP 413 DO 10.1001/archinte.1989.00390020113024 UL http://dx.doi.org/10.1001/archinte.1989.00390020113024 AB • An evaluation of the Garren-Edwards gastric bubble in the treatment of obesity was done. Several clinical trials have compared the effects of behavior therapy with and without the bubble, but the effects of the bubble alone have not been previously evaluated. Ten obese women averaging 91% overweight received the bubble without adjunctive therapy during a 12-week treatment period. Frequent psychological and laboratory measures as well as weight were obtained during the study to explore the possible mechanisms of the bubble's effect and its side effects. Mean weight change was −2.5 kg, with a range of −8.8 to +1.6 kg. Four patients lost more than 3.5 kg, three lost less than 3.5 kg, and three gained weight. The Garren-Edwards gastric bubble alone does not appear to provide significant benefit to most obese patients.(Arch Intern Med 1989;149:411-413)
