Detailed Description

The primary objective of this study was to collect additional information about the safety and effectiveness of the LAP-BAND AP System in a real-life clinical setting. Effectiveness was assessed through the collection of weight loss data, as well as other secondary effectiveness measurements. Safety was assessed by the incidence and severity of adverse events (AEs) related to treatment.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Percent Excess Weight
Time Frame: Baseline to 5 Years
Subjects' Percent Excess Weight Loss (%EWL) from baseline over the 5 year period post LAP-BAND implantation was measured. Excess Weight = Baseline weight - Ideal weight, where ideal weight is based on a BMI of 25 kg/m2.
Baseline to 5 Years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Subject BMI From Baseline to 5 Years Post LAP-BAND Implantation
Time Frame: Baseline to 5 years
Subjects' Body Mass Index (BMI) was recorded at each follow-up visit for the 5 years after LAP-BAND implantation.
Baseline to 5 years
Subject Reported Satiety
Time Frame: Baseline to 5 Years
Subjects rated their level of hunger, satiety after meals, and desire to eat at all follow-up visits. Level of hunger was rated using a 6-point scale: 0 = not hungry at all to 5 = as hungry as I have ever felt. Satiety after meals was rated using a 6-point scale: 0 = not at all full to 5 = as full as I have ever felt. Desire to eat was rated using a 6-point scale: 0 = no desire at all to 5 = extremely strong desire.
Baseline to 5 Years
Subject Reported Quality of Life
Time Frame: Baseline to 5 Years
Quality of Life was assessed using the Obesity and Weight-Loss Quality of Life Questionnaire (OWL-QOL-17). The OWL-QOL-17 is a survey of 17 questions, that rates quality of life on a scale of 0 (better) to 102 (lower).
Baseline to 5 Years
Subject Reported Sleepiness (Epworth Sleepiness Scale)
Time Frame: Baseline to 5 years
The Epworth Sleepiness Scale (ESS) is a questionnaire used to determine a subject's level of daytime sleepiness. Subjects rate his or her chances of dozing off in different situations, which are combined into a total ESS score that can vary between zero (low level of daytime sleepiness) and 24 (high level of daytime sleepiness).
Baseline to 5 years
