Area of Science:

  • Bariatric surgery and medical devices
  • Gastroenterology
  • Obesity medicine

Background:

  • Intragastric balloons (IGBs) are effective for weight loss, but responder rates are not always reported.
  • The Spatz3 adjustable intragastric balloon (AIGB) offers extended implantation, volume reduction for intolerance, and volume increase for diminishing effects.

Purpose of the Study:

  • To determine the efficacy and responder rate of the Spatz3 AIGB.

Main Methods:

  • Retrospective review of 165 Spatz3 AIGB implantations across two centers.
  • Analysis of patient demographics (mean BMI 35.7, mean weight 99.1 kg) and balloon volumes (mean 495 ml).
  • Evaluation of balloon volume adjustments for intolerance and weight loss plateaus.

Main Results:

  • A mean weight loss of 16.3 kg (16.4% TBWL) was achieved in 165 patients.
  • 88.5% of patients (146/165) met responder criteria (≥25% EWL or ≥10% TBWL).
  • Responder rates were higher in patients with BMI < 40 (91.2%) compared to BMI > 40 (69%).
  • Volume adjustments (down: -150 ml; up: +260 ml) improved therapy continuation and yielded additional weight loss (5.7 kg).
  • One case of gastric perforation (0.6%) and five cases of small ulcers were reported.

Conclusions:

  • The Spatz3 AIGB demonstrates effectiveness for weight loss, particularly in patients with BMI < 40.
  • Adjustable volume features are crucial for maintaining therapy and achieving high responder rates.
  • Volume adjustments significantly contribute to sustained weight loss and patient adherence.
