Quality of Life 10 Years After Bariatric Surgery

Study Overview
=================
Brief Summary
-----------------
Importance: Improvement of the QoL after bariatric surgery is an important outcome of the treatment. The investigators believe that assessment of distant QoL results, could provide new insight into effectiveness of most popular bariatric procedures. Objective: The investigators aim to analyze the bariatric surgery effect on the long term QoL, considering the type of surgery. Design: A cohort study including patients undergoing bariatric surgery. Setting: One academic referral center. Exposures: Patients undergo Laparoscopic Sleeve Gastrectomy or Laparoscopic Roux-en-Y Gastric Bypass . Surgical technique is standardized and consistent in the whole study group. Main Outcomes and Measures: The main outcome is the change of QoL after bariatric surgery. It is assessed in three different time points: pre-surgery, first follow up (1 year after surgery) and second follow-up (10 years after surgery). The investigators use two licensed and standardized questionnaires: (Short Form Health Survey) and MA-QoLQII (Moorehead-Ardelt Quality of Life Questionnaire II).

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Quality of life measured as a Short Form Health Survey - 36 score. | To assess the quality of life of included patients the investigators used licensed and standardized questionnaire, which is designed for medical purposes: SF-36 (Short Form Health Survey). It is scale with minimal value being 0 and maximal value being 100 scale. Higher score means better outcome. | 10 years | 
| Quality of life measured as a Moorehead-Ardelt Quality of Life Questionnaire II score. | To assess the quality of life of included patients the investigators used licensed and standardized questionnaire, which is designed for medical purposes: MA-QoLQII (Moorehead-Ardelt Quality of Life Questionnaire II). The MA-QoLQII questionnaire has six dimensions. The MA II questionnaire is used as a part of the Bariatric Analysis and Reporting Outcome System (BAROS) and assesses the patients subjective impression of quality of life in the areas of general self-esteem, physical activity, social contacts, satisfaction concerning work, pleasure related to sexuality and focus on eating behavior. Each item is scored from-0.5 to +0.5. The total score consists of the sum of the six dimensions with a range of -3 to +3. A total score of 1.1 to 2 is considered good, above 2.1 isvery good. | 10 years |
