The Application of Gastric Bypass Stents in Patients with Weight Regain After Laparoscopic Sleeve Gastrectomy：a Feasibility Study

This study is based on the National Center for Integrated Traditional Chinese and Western Medicine, utilizing the centralized advantages of our department and integrating multiple disciplines (general surgery, endocrinology, nutrition, sports, and traditional Chinese medicine). It focuses on the effectiveness of gastric bypass stents in treating patients with postoperative obesity after laparoscopic sleeve gastrectomy, as well as in patients with simple obesity. This will improve the prognosis of patients and reduce the medical burden.

Inclusion Criteria:

• 1、For those with simple obesity, BMI ≥ 32.5, or 27.5 ≤ BMI < 32.5, who have difficulty controlling their condition with lifestyle modifications and medical treatment, and who meet at least two criteria for metabolic syndrome components, or have comorbidities.

  2、For those with simple obesity, 27.5 ≤ BMI < 32.5, and with male waist circumference ≥ 90 cm, female waist circumference ≥ 85 cm, and imaging studies suggesting central obesity.

  3、For those with type 2 diabetes, BMI ≥ 27.5, who still have some residual insulin secretion capacity.

Exclusion Criteria:

• 1、Non-obese type 1 diabetes; 2、Those for whom the purpose of treatment is T2DM, but whose pancreatic beta-cell function is largely lost, with a BMI < 25.0; 3、Age < 16 years or age > 65 years; 4、Pregnant women with diabetes and patients with certain special types of diabetes; 5、Those with a cognitive disorder or immature intelligence, and who cannot control their behavior; 6、Those whose expectations for the surgery are not realistic; 7、Those unwilling to assume the risks of potential surgical complications; 8、Those unable to comply with postoperative dietary and lifestyle changes, showing poor compliance; 9、Those in poor general health, who are unable to tolerate general anesthesia or surgery.
