Abstract: Objective To investigate the clinical curative effect and feasibility of sleeve gastrectomy plus jejunal bypass(SG + JJB). Methods The clinical data of 97 patients with BMI ≥ 35 kg/m2 who underwent bariatric surgery from January 2015 to December 2017 were analyzed retrospectively.They were divided into three groups according to the operation method,of which 37 cases in SG + JJB group were treated with SG + JJB,29 cases in SG group were treated with SG,and 31 cases in RYGB group were treated with RYGB.The weight loss,diabetes remission and Surgical complaints were compared between 3 years after operation.Results The average percentage of total weight loss(% TWL) in SG + JJB group was higher than that in SG group[(35.3±9.0)% vs (31.7±7.2)%],the difference was statistically significant(P<0.05),which was equivalent to that in RYGB group.The remission rate of diabetes in group SG+JJB was similar to those in group SG and RYGB.The incidence of postoperative abdominal distension in SG + JJB group was higher than that in SG group(18.9% vs 0,P<0.05),and the incidence of postoperative gastroesophageal reflux disease(GERD) was higher than that in RYGB group(16.2% vs 0,P<0.05).Conclusion The weight loss effect of SG + JJB is better than that of SG,which is similar to RYGB.Compared with SG,SG + JJB has an increased risk of abdominal distension.Compared with RYGB,the incidence of gastroesophageal reflux increased.
