Background: The Spatz3 Adjustable balloon system is approved for 1 year implantation and allows multiple
changes in the balloon volume during the course of implantation. Other intragastric balloons are approved for 6
months and their balloon volumes remain the same for the entire 6 months of implantation.
Aims: To determine the utility and efficacy of adjustment of the Spatz intragastric balloon.
Methods: The results of 239 patients in 7 series of Spatz balloon patients were reviewed to determine the effect of
balloon volume adjustment during the 1 year course of therapy with the Spatz and Spatz3 adjustable balloons.
Patient weights were measured prior to balloon volume adjustment and at extraction. Adjustments were made for
intolerance or weight loss plateau.
Results: The group’s mean BMI was 37.1(28.7-73); mean weight 102.1 kg (71.6-210.3); mean age 41 (19-70);
168 female and 71 males; mean balloon volume at implantation 468 ml (400-600 ml). Balloon volume adjustments
were performed in 132 patients: 26 downward adjustments of a mean 170 cc (100-200) which alleviated early
intolerance in all pts;
106 upward adjustments were performed as shown in the Table below:
133 pts that did not undergo upward adjustment lost a mean 1.4 kg from month 5 to month 12 compared with the
8.9 kg weight lost by the adjusted group of patients. The 1 year mean wt loss for the 106 upward adjusted pts was
20.4 kg with 18.2 %wt loss and 43.4 %EWL. The 1 year mean wt loss for the non-adjusted patients was 16.4 kg
with 15.2 %wt loss and 39.7 %EWL.
Conclusions: The adjustability function of the Spatz balloon serves 2 functions: alleviating early intolerance, and
yielding extra weight loss for those with weight loss plateau.
