[Current status of sleeve gastrectomy plus jejunojejunal bypass]

At present, sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) have become the major bariatric and metabolic surgical procedures, but neither of them is perfect. Adding jejunojejunal bypass (JJB) to SG can enhance weight loss and hypoglycemic effect. Present clinical results show that the short-term weight loss effect of SG-JJB is better than SG, and the weight loss and hypoglycemic effect is similar to RYGB. However, SG-JJB does not have various complications like traditional jejunal ileal bypass (JIB). The existing evidence shows that SG-JJB is a safe and effective bariatric and metabolic surgery, with relatively simple technical requirement. Meanwhile, SG-JJB has almost no dumping syndrome or ulcers, and facilitates endoscopic examination of the biliary tract, and has no blind gastric pouch. Thus, SG-JJB has some clinical application prospects, but further high-quality research with long-term follow-up is needed.
