Primary outcome measure
Treatment success, evaluated at 6 and 12 months, based on patients glycaemic control measured by achieving HbA1c level less than 7% as per the ADA recommendation.
Secondary outcome measures
1. Improvement in physiological measurements (glycaemic control, lipids) (success determined at 6 and 12 months)
2. Co-morbidity improvement, determined by comparing pre-operative co-morbidities to the status post-operatively (success determined at 12 months)
3. Improvement in Quality of Life using the 36-item Short Form (SF-36) questionnaire, determined by comparing pre-operative to post-operative quality of life (success determined at 12 months). We have licensed the SF-36 questionnaire from Quality Metrics and will utilise their guide for interpreting the data
