sleeve gastrectomy with uncut jejunal bypass (sg-uncut jjb) verus sleeve gastrectomy in obese patients

Conditions: Excessive Weight Loss; Total Weight Loss; Sleeve Gastrectomy; Jejunojejunal Bypass; Uncut

Summary: among various bariatric procedures, sleeve gastrectomy (sg) and roux-en-y gastric bypass (rygb) are the most frequently performed procedures worldwide. though sg provides similar weight loss effect to rygb in short-term follow-up, its long-term and very long-term weight loss effect was reported to be inferior to rygb. weight regain after sg remains the major concern after 2-year follow-up due to gradual loss of appetite suppression and lack of malabsorption function. sg plus procedures have been developed to strengthen the effect of sg on diabetes control. it has been reported that sg plus jejunojejunal bypass (sg - jjb) offered better weight loss than sg and similar weight loss to rygb. the present study aims to evaluate the efficacy and safety of sleeve gastrectomy plus uncut jejunojejunal bypass (sg - uncut jjb).
