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.

Outcome Measures

Primary Outcomes (1)

  • the excess weight loss effect of different metabolic surgeries after 1year

    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)

    1 year after surgery

Secondary Outcomes (8)

  • the adverse events rate of different metabolic surgeries

    30 days after surgery

  • the excess weight loss effect of metabolic surgery with long-time follow-ups

    3 years

  • the excess weight loss effect of metabolic surgery with long-time follow-ups

    5 years

  • the excess weight loss effect of metabolic surgery with long-time follow-ups

    10 years

  • the glycemic control level of metabolic surgery with long-time follow-ups

    1 year after surgery

  • +3 more secondary outcomes
