Objective: To compare the safety, weight loss, and metabolic outcomes of patients with obesity with sleeve gastrectomy (SG) or sleeve gastrectomy plus uncut jejunojejunal bypass (SG-uncut JJB).
Methods: This prospective study included patients with BMIs ≥ 32.5 kg/m2 or refractory metabolic disorders undergoing SG or SG-uncut JJB between January and December 2020 in our hospital (NCT04534504). Weight loss, metabolic outcomes, surgical results, and complaints during 1-year follow-up were compared between two groups.
Results: Forty-seven patients were enrolled, 26 in the SG and 21 in the SG-uncut JJB groups. A longer operative time was observed in the SG-uncut JJB than in the SG group (140 (110-180) min vs. 90 (70-180) min, P = 0.001). No significant differences were found in complications. Total weight loss (TWL%) and excess weight loss (EWL%) in both groups increased with the duration of follow-up (P = 0.001). TWL% was greater at 1 month ((11.1 ± 2.4)% vs. (8.2 ± 4.4)%, P = 0.011] and 12 months [(29.7 ± 6.9)% vs. (20.3 ± 7.2)%, P = 0.001) with SG-uncut JJB than with SG. SG-uncut JJB and SG had similar metabolic outcomes and complaints during the 1-year follow-up, but less nausea was reported with SG-uncut JJB (9.2% vs. 46.2%, P = 0.006).
Conclusion: In short-term follow-up, SG-uncut JJB was a safe and effective bariatric surgery procedure in patients with obesity.
