Weight loss trend after BARIATRIC SURGERY in a population of obese patients

Background and aims Bariatric Surgery (BS) is a therapeutic option in patients with severe obesity whose non-surgical techniques have failed. No work has previously explored trajectories of weight loss how long this was maintained. Aim study to describe effect BS nutritional intervention on body trend obesity. Methods 792 who underwent from 1996 2021 were included. The Protocol provides Laparoscopic Sleeve Gastrectomy (LSG), Vertical Gastroplasty (VBG) Roux-en-Y Gastric Bypass (GB). %Total Weight Loss (%TWL) %Excess (%EWL) evaluated three cohort patients. Cumulative incidence clinical goal after surgery calculated at two five years BS. Results At follow-up, average %TWL %EWL 31.2% (95% CI = 29.0 - 33.4%) 71% 65.4 76.5%) for VBG, 34.7% 33.8 35.6%) 78.0% 75.9 – 89.1%) GB 33.8% 32.5 35.1%) 68.8% 66.1 71.6%) LSG. the cumulative 70.7% 59.1 79.1%) 86.4% 82.4- 89.6%) 83.4% 76.0 87.1%) surgery, % TWL EWL 22.5% 10.2 34.8%) 58.2% 28.4 88.1%) 31.8% 30.2 33.3%) 70.8% 67.5 74.1%) 29.5% 26.2 32.8%) 62.0% 53.4 -70.6%) LSG respectively. having reached share people able maintain their 49.5% 30.8 79.6%) 69.5% 58.3 82.8%) 55.9% 42.1 74.3%) median time maintaining 4.8 VBG lower limit 4.1), 6.6 6.2) 5.3 4.8). Conclusions Our confirm effectiveness show that do not reach within 2 years, hardly will it later suggest necessity medium long-term follow-up prevent regain.
