数据采集和管理（说明：数据采集和管理由两部分组成，一为病例记录表(Case Record Form, CRF)，二为电子采集和管理系统(Electronic Data Capture, EDC)，如ResMan即为一种基于互联网的EDC：

Based on national obesity surgery database, the data will be collected at the time of SG and OAGB/MGB including age, gender, weight, height, nadir weight, BMI, percent excess weight loss (%EWL): %EWL=[(Initial Weight) – (Post-Op Weight)]/[(Initial Weight) – (Ideal Weight)] [7] and conversion indication. Some obesity-related comorbidities including type-2 Diabetes Mellitus (DM), arterial Hypertension (HTN), dyslipidemia, Obstructive Sleep Apnea (OSA) and GERD. Weight indicators and comorbidity outcomes are evaluated 1, 2, 3 and 5 years after the conversion surgery. The changes in comorbidities are classified in five categories: No change, remission, improvement, new onset and recurrence, which are assessed according to standardized outcomes reporting in metabolic and bariatric surgery.
