Greater China Metabolic and Bariatric Surgery Database

• Conditions: Metabolic Surgery

• Registration Number: NCT03800160
• Lead Sponsor: Beijing Friendship Hospital

Brief Summary

Metabolic surgery, as a recognition treatment option for patients with clinical morbid obesity, is gaining increasing appreciation. In addition to substantial weight loss, emerging studies have highlighted that metabolic surgery can substantially ameliorate obesity-related metabolic diseases, including but not limited to type 2 diabetes mellitus (T2DM), hypertension, dyslipidemia, obstructive sleep apnea-hypopnea syndrome (OSAHS) and polycystic ovary syndrome (PCOS)in severely obese patients. However, further investigations with larger sample size and longer observation time still needed to clarity the efficacy and safety of metabolic surgery in Chinese patients with obesity and encouraging future research in this field.

Primary Outcome Measures

Name	Time	Method
the excess weight loss effect of different metabolic surgeries after 1year	1 year after surgery	Percent excess weight loss (%EWL), %EWL=\[(initial weight)-(post-op weight)\]/\[(initial weight)-(ideal weight)\] (in which "ideal weight" is defined by the weight corresponding to a BMI of 25 kg/m2)

Secondary Outcome Measures

Name	Time	Method
the excess weight loss effect of metabolic surgery with long-time follow-ups	10 years	Percent excess weight loss (%EWL), %EWL=\[(initial weight)-(post-op weight)\]/\[(initial weight)-(ideal weight)\] (in which "ideal weight" is defined by the weight corresponding to a BMI of 25 kg/m2)
the glycemic control level of metabolic surgery with long-time follow-ups	10 year after surgery	the change of HbA1c, glucose level, C-peptide and insulin levels
the adverse events rate of different metabolic surgeries	30 days after surgery	show the surgical safety by 30 days follow-up according to guideline（such as: bleeding, leak, obstruction, re-operation for complication）
