Short-Term Outcomes of Sleeve Gastrectomy plus Jejunojejunal Bypass: a Retrospective Comparative Study with Sleeve Gastrectomy and Roux-en-Y Gastric Bypass in Chinese Patients with BMI ≥ 35 kg/m2.

Bariatric surgery represents the most effective treatment for obesity and its related comorbidities. The present study aims to evaluate the efficacy and safety of sleeve gastrectomy plus jejunojejunal bypass (SG + JJB).

This retrospective study included 244 obese patients with BMI ≥ 35 kg/m² undergoing SG + JJB (n = 83), SG (n = 82), and Roux-en-Y gastric bypass (RYGB) (n = 79). Postoperative weight loss, metabolic outcomes, nutrition status, and patients' complaints at 1-year follow-up were compared. Subgroup analyses (36 pairs of SG + JJB/SG and 37 pairs of SG + JJB/RYGB) were performed to compare weight loss and lipid profiles after matching with gender, age, and BMI.

In subgroup case-matched study, SG + JJB exhibited superior weight loss effect to SG regarding total weight loss (38.8 ± 8.7% vs 35.0 ± 6.1%, P = 0.011) and excessive weight loss (95.3 ± 20.4% vs 86.9 ± 13.7%, P = 0.033) at 1-year follow-up. The postoperative metabolic outcomes, nutritional status, and patients' complaints were similar between SG + JJB and SG. SG + JJB yielded similar weight loss, T2DM remission, and hypertension resolution to RYGB at 1-year follow-up, but less postoperative complications than RYGB regarding anemia (4.8% vs 22.8%), vitamin D deficiency (47.0% vs 65.8%), vitamin B12 deficiency (8.4% vs 25.3%), hypoalbuminemia (1.2% vs 8.9%), diarrhea (6.0% vs 21.5%), dumping syndrome (0 vs 7.6%), and fatigue (25.3% vs 40.5%) (P < 0.05). In subgroup case-matched study, RYGB improved total cholesterol and low-density lipoprotein better than SG + JJB (P < 0.05).In short-term follow-up, SG + JJB offered better weight loss than SG and similar weight loss to RYGB. SG + JJB resulted in less postoperative nutritional deficiency and complications than RYGB except for lipid and hypertension improvement.
