First received: July 28, 2009
Last updated: October 6, 2014
Last verified: October 2012
The purpose of this study is to collect additional safety, performance and effectiveness data of the Easyband gastric band medical device in the treatment of morbid obesity in 4 European countries where the device is a CE marked approved product.

Condition Intervention
Morbid Obesity Device: Easyband®

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Prospective
Official Title: EU Post-Market Study on Easyband®

Further study details as provided by Allergan ( Allergan Medical ):

Primary Outcome Measures:
  • Feasibility and Ease of Implantation [ Time Frame: < 1day ]
    Percent of subjects whose device implantation was rated by the surgeon as a 1 or 2 on a 5-point scale, where 1 is "very easy" and 5 is "impossible."

Secondary Outcome Measures:
  • % Excess Weight Loss [ Time Frame: 12 months ]
    Percent excess weight loss was defined as weight loss divided by excess weight multiplied by 100, where weight loss was equal to baseline weight minus follow-up weight, and excess weight was equal to baseline weight minus ideal weight.

  • Change in BMI [ Time Frame: 12 months ]
    Decrease in body mass index (BMI; measured in kg/m2) from baseline to 12 months

  • Change in Weight [ Time Frame: 12 months ]
    Change in weight (in kilograms) at baseline to 12 months

Enrollment: 112
Study Start Date: April 2009
Study Completion Date: December 2011
Primary Completion Date: October 2011 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Subjects who had the Easyband device implanted laparoscopically.
Device: Easyband®
The Easyband adjustable gastric band device is implanted laparoscopically around the top of the stomach to create a small pouch. Adjustments to increase or decrease the stoma size are made non-invasively by telemetric connection between an internal and external antenna.
