In recent years, bariatric surgery has grown rapidly worldwide and has become an important branch of general surgery. Due to the rapid development of minimally invasive laparoscopic surgical techniques, the safety of bariatric surgery has been dramatically improved. Modern surgical techniques have been able to minimize complications. The public has some misconceptions about the risks of bariatric and diabetic surgery, and that the risks of surgery are not as high as they are thought to be. In fact, the mortality rate of bariatric and diabetic surgery has been shown to be lower than other common surgeries, such as cholecystectomy. Weight loss surgery is done laparoscopically or with the da Vinci Surgical Robot. Traditional open surgery is backwardly eliminated, and with the magnification of the laparoscope, the operation is more delicate, bleeding is less than 30m, and the procedure takes about 100 minutes, and the patient can get out of bed on the first day after surgery and be discharged in about 3 days. The number of cases operated by the surgeon is directly proportional to the safety of the operation, with 50 cases as the threshold and 500 cases as the maturity point. The more cases operated, the higher the safety, the shorter the operation time, the smaller the bleeding, the lower the complication rate, and the shorter the hospital stay. In the obese population, patients who did not undergo surgery had an 8-fold increased risk of death compared to those who underwent bariatric surgery; whereas patients who underwent bariatric versus diabetic surgery had a significantly lower relative risk of death by 89% compared to those who did not undergo surgery. The risk of bariatric and diabetic surgery is lower than that of laparoscopic cholecystectomy, which is a relatively low risk. To ensure the safety and effectiveness of the surgery, in addition to the attending surgeon, bariatric surgery at our hospital has extremely high qualification requirements for anesthesiologists, ICU doctors, health managers, nutritionists and other multidisciplinary team members, who strictly control all aspects and work together to protect the health of patients.
