简要总结
Single anastomosis sleeve ileal bypass (SASI) is an improved surgical technique for sleeve gastrectomy (SG), which combines the advantages of SG and Roux-en-Y gastric bypass (RYGB) while avoiding their disadvantages,in order to achieve better treatment outcomes.On the one hand,SASI surgery improves the effectiveness of weight loss surgery by adding gastrointestinal anastomosis on the basis of SG,while reducing gastric pressure and improving postoperative gastroesophageal reflux symptoms.On the other hand,it also avoids the regret of RYGB surgery leaving the stomach open for gastroscopy examination and reduces the risk of postoperative nutrition related complications.Therefore,SASI surgery has demonstrated good application prospects and is expected to be promoted in clinical practice.So far,there has been no comparative study of RCTs between RYGB and SASI internationally.In order to compare the weight loss effects of SASI and RYGB surgery,this study intends to conduct a randomized controlled trial on patients who meet the criteria and require weight loss surgery,providing high-level evidence-based medicine for the further clinical development of SASI surgery in the future.
详细描述
Routine preoperative examinations should be conducted on patients planning to undergo weight loss surgery,and inclusion screening should be conducted according to the inclusion and exclusion criteria.Patients who meet the inclusion criteria will receive informed consent before enrollment and be randomly assigned to either the experimental group (SASI group) or the control group (RYGB group) for weight loss surgery based on computer randomization results.
Monitor the patient's surgical condition and surgical complications before discharge.
Follow up will be conducted at each follow-up node after surgery (1 month/3 months/6 months/12 months).
This study aims to measure the weight of patients before and after surgery, analyze the degree of weight loss based on the percentage of excess weight loss (% EWL) one year after surgery, and compare the weight loss effects of two surgical procedures.At the same time,based on relevant laboratory results,the effectiveness of two surgical procedures for treating metabolic syndrome,the incidence of postoperative nutritional complications,the incidence of surgical related complications,the quality of life one year after surgery,and weight loss were compared.
