Core Tip
Core Tip: In this single-center retrospective study, 122 Chinese adults with obesity underwent laparoscopic sleeve gastrectomy and were followed up for 12 months. Mean body mass index fell from 38.7 kg/m2 to 30.3 kg/m2, excess weight loss reached 71.8%, and 72% of patients achieved effective weight loss. Among 28 patients with type 2 diabetes, 54% achieved complete remission; significant reductions were also observed in hypertension, hyperuricemia, and fatty liver. No major surgical complications were observed. These results confirm that laparoscopic sleeve gastrectomy produces rapid, sustained weight loss and broad metabolic benefits within the first postoperative year.
