摘要
The objective of this study is the comparison of a new intragastric balloon recently introduced, the Adjustable Balloon System (ABS), with the BioEnterics intragastric balloon (BIB) in terms of tolerance, safety, and weight loss parameters.
A case-control study was done: 40 patients were matched with 80 controls. To achieve the same duration therapy (12 months), a single ABS positioning was compared with a BIB followed by another BIB (6 + 6 months). Length of procedure, hospital stay, complications, and weight loss parameters after 6 months (time of first BIB removal) and after 12 months from baseline (time of Spatz and second BIB removal) were considered. Statistical analysis was done by means of Student's t test, chi 2 test, or Fisher's test. P < 0.05 was considered significant.
Mortality, positioning, and extraction complications were absent. Both the devices were well tolerated with slight duration of post placement symptoms. During this study, the Spatz balloon was adjusted with inflation of 200 cm(3) of saline (total, 800 cm(3)) in 9/40 (22.5 %) patients, for poor weight loss after first 6-months treatment. In the Spatz group, there occurred 7/40 complications linked to the device and in 6/7 patients the balloon was removed. At the end of the study, the weight loss parameters were similar between groups: BMI 31.0 +/- 11.8 (Spatz group) vs 31.3 +/- 12.3 (BIB group) (p = Ns).
The idea of dynamic balloon therapy needs to be confirmed with wider series. The rate of complication reported is very high, and several studies regarding safety and efficacy are needed.
