Brief Summary

Study objectives:

  1. 1.generate local clinical, health-related quality-of-life and health economic data to evaluate the benefits of two types of minimally invasive weight-loss surgery
  2. 2.support multi-disciplinary bariatric sites in Germany by providing structured procedure guidelines and training, therefore facilitating procedural adoption, increasing safety and shortening the learning curve for weight-loss surgery.

Outcome Measures

Primary Outcomes (3)

  • Quality of Life (QOL) in First Postoperative Year According to EuroQol-5 Dimensions-5 Levels (EQ-5D-5L)

    The EQ-5D-5L (minimum and maximum values are 0 and 1 respectively) consists of two sections,the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS).The EQ-5D descriptive system comprises the following five dimensions: mobility,self-care,usual activities (e.g.,work, study..), pain/discomfort and anxiety/depression with five response levels for each dimension:no problems,slight problems, moderate problems,severe problems and extreme problems.The EQ-5D VAS is a 20 cm vertical scale where patients can mark from 0 (worst health imaginable) to 100 (best health imaginable).The global score at each timepoint is calculated as a composite of the five dimention score and of the VAS health score according to a specific algorithm.The Aurea Under the Curve (AUC) of QOL as assessed by EQ-5D-5L is reported to combine repeated measurements at flexible time intervals between 0 and 12 months post-procedure into a single numeric value.The higher the AUC value is,the better the patient is.

    12 Months

  • Quality of Life (QOL) in First Postoperative Year According to Bariatric Analysis and Reporting System (BAROS) With the Moorehead-Ardelt Quality of Life Questionnaire II (M-A QoLQ II)

    The BAROS consists of a scoring table that includes three main areas of analysis: weight loss, improvement of medical conditions and M-A QoLQ II. Points are added or subtracted according to changes in these domains. A maximum of three points is given to each domain to evaluate changes after medical or surgical intervention. Points are deducted for complications or reoperations. The M-A QoLQ II assesses six important QoL items (self-esteem, physical activity, social life, work conditions, sexual activity and eating behaviour) on a scale ranging from -0.50 to 0.50 with 0.10 increments to assess each item. The total number of points (range -7 to 9) defines five outcome groups from failure to excellent. The Aurea Under the Curve (AUC) of QOL as assessed by BAROS with M-A QoLQ II is reported to combine repeated measurements at flexible time intervals from 0 to 12 months post-procedure into a single numeric value. The higher the AUC value is, the better the patient is.

    12 months

  • Quality of Life (QOL) in First Postoperative Year According to Impact of Weight on Quality of Life-Lite Questionnaire (IWQOL-Lite)

    The IWQoL-Lite consists of five domains: physical function (11 items), self-esteem (7 items), sexual life (4 items), public distress (5 items), and work (4 items). Each item has five response options: never true-1, rarely true-2, sometimes true-3, usually true-4, and always true-5. In computing raw and normalized scores, a pro-rated system is used for handling missing data. Normalized scores are used to obtain scores ranging from 0 (worst QoL) to 100 (best QoL). The Aurea Under the Curve (AUC) of QOL as assessed by IWQOL-Lite questionnaire is reported to combine repeated measurements at flexible time intervals from 0 to 12 months post-procedure into a single numeric value. The higher the AUC value is, the better the patient is.
