title: Does the intragastric balloon have a predictive role in subsequent LAP-BAND(®) surgery? Italian multicenter study results at 5-year follow-up.
abstract: BACKGROUND
  The intragastric balloon has been reported to be a safe and effective tool for temporary weight loss. The aim of this study is the evaluation of the possible predictive role of intragastric balloon when used before laparoscopic adjustable gastric banding.
  
  
  METHODS
  A longitudinal multicenter study was conducted in patients with body mass index (BMI)>35 kg/m(2) who underwent gastric banding with the BioEnterics Intragastric Balloon (BIB). After balloon removal (6 mo), patients were allocated into 2 group according to their percentage of excess weight loss (%EWL): group>25 (%EWL>25%) and group<25 (%EWL<25%). Patients from both group underwent laparoscopic adjustable gastric banding (LAGB) 1-3 months after BIB removal. The LAP-BAND AP band was placed in all patients via pars flaccida. Weight loss parameters were considered in both groups.
  
  
  RESULTS
  From January 2005 to December 2009, 1357 patients were enrolled in this study. Mean BMI at time of BIB positioning was 44.9±8.4 (range 29-82.5). After 6 months, at time of removal, mean BMI was 39.4±7.3. According to the cutoff, patients were allocated into group A (n = 699) and group B (n = 658). At this time the mean BMI was 36.4±6.4 and 42.7±6.9 (P = .001) in groups A and B, respectively. At 1-year follow-up from LAGB, mean BMI was 35.8±6.5 and 40.0±7.4 (P<.001) in groups A and B, respectively. This significant difference was confirmed at 3- and 5-year follow-ups. A similar pattern was observed with the %EWL.
  
  
  CONCLUSIONS
  Satisfactory results with BIB are predictive of a positive outcome of LASB at 1, 3, and 5 years after the procedure, and poor results do not inevitably indicate a negative outcome for gastric banding.
