ABSTRACT
BACKGROUND: Saline-filled intragastric balloons (IB) may be inserted for 6 months to promote weight loss. We aimed to assess potential benefits of repeating IB therapy. METHODS: One hundred eighteen consecutive subjects (median body mass index, 34.0 kg/m(2); interquartile range [IQR], 31.2-36.9) treated with IB were included in a prospective non-randomized multicenter study. RESULTS: Nineteen (16%) subjects had repeat IB therapy at their own request, either to prolong first treatment (n = 8) or after a IB-free interval (n = 11). Higher weight loss 3 months after first IB insertion independently predicted repeat therapy (P = 0.008). Median weight loss in subjects who had repeat therapy was lower with second vs first IB (9.0 vs 14.6 kg; 30.4% vs 49.3% excess weight [EW]; P = 0.003). Compared to subjects with single treatment (n = 99), those with repeat treatment (n = 19) had greater weight loss at first IB extraction (14.6 vs 11.0 kg; 49.3% vs 30.7% EW; P = 0.026) and 1 year later (12.0 vs 6.0 kg; 40.9% vs 20.8% EW; P = 0.008) but the difference became less than 2 kg starting at 3 years. At final follow-up (4.9 years; IQR, 3.4-6.7), the whole subject population had lost a median of 2.0 kg (IQR, -3.0 to 10.3) or 6.2% EW (IQR, -8.1 to 31.6) and identical proportions of subjects with single/repeat treatment had >or=10% baseline weight loss (26%) or bariatric surgery (32%). CONCLUSION: Higher weight loss at 3 months independently predicted repeat IB therapy; weight loss with the second IB was lower compared to first IB. Repeat treatment had no effect on proportions of subjects with >or=10% baseline weight loss or bariatric surgery at final follow-up.

BACKGROUND: Intragastric band migrations or dysfunctions are common long-term complications of both vertical banded gastroplasty (VBG) and laparoscopic adjustable gastric banding (Lap-Band) that classically require surgical treatment. OBJECTIVE: In this series, we describe the endoscopic removal of partially eroded Lap-Bands or Silastic rings and noneroded dysfunctioning rings after VBG. DESIGN: Case series. SETTING: A European, tertiary-care academic center. PATIENTS: This study involved 13 patients--3 with eroded Lap-Bands, 4 with eroded Silastic rings, and 6 with refractory outlet stoma stenosis after VBG. INTERVENTION: Endoscopic removal was performed within 1 or 2 sessions, according to the presence and extent of band erosion at presentation, including optional placement of a self-expandable plastic stent across the band, followed about 6 to 8 weeks later by extraction with transsection, if needed, by using a wire-cutting system. MAIN OUTCOME MEASUREMENTS: Technical success and safety. RESULTS: One failure was caused by huge adhesion formation around a Lap-Band on the lesser curvature of the stomach and the left liver lobe. Twelve of 13 endoscopic removals were successful in 1 (n = 2) and 2 (n = 10) sessions. LIMITATIONS: Highly selected patients (tertiary-case academic center). CONCLUSION: Endoscopic removal of dysfunctioning bands or rings is safe and feasible by the use of a 1- or 2-step endoscopic procedure.
