Objective To investigate the effect of laparoscopic Roux-en-Y gastric bypass surgery(LRYGB)in the treatment of obese diabetes.Methods The clinical data of 20 obese diabetic patients who received LRYGB from 2012 to 2018 in the Minimally Invasive and Herniac Abdominal Surgery Center of Xinjiang People's Hospital were retrospectively analyzed.Result The all 20 surgeries were successfully completed,and 1 case was converted to open surgery.The surgical time ranged from 60 to 420 minutes,with an average of(150±105.64)minutes,the intraoperative blood loss ranged from 20 to 100,with an average of(37.5±20.99)ml,and the postoperative hospital stay ranged from 5 to 15,with an average of(8.25±2.51)days.Complications occurred in 7 cases(35.00％)within 5 years after surgery,all of which were Clavien Dindo grade Ⅱ.The body weight,BMI,glycosylated blood glucose,fasting blood glucose,and the percentage of total weight loss(TWL％)at 1,3,and 5 postoperatively improved compared with those before surgery(P＜0.05).15 cases(75.00％)of type 2 diabetes were completely relieved by LRYGB 5 years after operation.Conclusion Laparoscopic gastric bypass surgery is an effective way to reduce weight and blood sugar in obese patients with type 2 diabetes.

Foregut surgery has emerged as a new discipline in recent years,gaining attention at home and abroad.It mainly focuses on benign diseases of the stomach and esophagus,covering conditions such as gastroesophageal reflux disease,achalasia,and bariatric metabolic surgery.However,in some countries,foregut surgery also includes malignant diseases,such as esophageal and gastric cancers.Robotic surgery,one of the most advanced techniques available,is increasingly applied in clinical practice.The unique ergonomic design of robotic surgical systems allows surgeons to control the instruments with greater precision and finesse,thereby minimizing damage to surrounding vital tissues and organs.Robotic surgery is gradually becoming a major focal point in the field of anterior foregut surgery.However,its curr-ent limitations in China include high equipment and maintenance costs,as well as strict requirements for operator qualifications and operating room conditions.As robotic technology continues to develop and improve,it is expected that robot-assisted surgery will play an increasingly important role in foregut surgery,helping doctors improve the quality of surgery and provide better treatment outcomes for patients.
