Brief Summary:
The purpose of this study is to evaluate the LAP-BAND AP System in severely obese patients.

Condition or disease Intervention/treatment
Obesity, Morbid Device: LAP-BAND AP Adjustable Gastric Banding System

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.

Study Type : Observational
Actual Enrollment : 521 participants
Observational Model: Case-Only
Time Perspective: Prospective
Study Start Date : June 2007
Actual Primary Completion Date : August 2013
Actual Study Completion Date : November 2013

Group/Cohort Intervention/treatment
Patients who receive the LAP-BAND AP Adjustable Gastric Banding System.
Device: LAP-BAND AP Adjustable Gastric Banding System
Reduction of food intake due to creation of smaller stomach pouch.

Primary Outcome Measures :
  1. 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.

Secondary Outcome Measures :
  1. 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.

  2. 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.

  3. 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).

  4. 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).
