EP.TH.30Effect of One Anastomosis Gastric Bypass on Haematinics, Vitamin D, and Parathyroid Hormone Levels: A comparison between 150 cm and 200 cm Bilio-Pancreatic Limb

Abstract Introduction There is little data on the effect of One Anastomosis Gastric Bypass (OAGB) Haematinics, Vitamins D, and Parathyroid Hormone levels. It further unclear if an OAGB with a Bilio-Pancreatic Limb (BPL) 150 cm (OAGB-150) would deliver better outcomes than that BPL 200 (OAGB-200). Methods We investigated our records to obtain information patients who underwent OAGB-200 or OAGB-150 until 31st July 2018 in unit. Results A total 405 either (n = 234) 171). The mean age was 46±10.98 years 276 (67.3%) were females. preoperative weight Body Mass Index (BMI) 139±29.96 kg 49±8.14 kg/m2 respectively. With there significant increase anaemia rates at 1 2-years compared levels fall haemoglobin After but rate only 2-years. PTH number abnormal values OAGB-200. OAGB-150, changes 2 only. Conclusion Both are associated secondary hyperparathyroidism. Our findings should prompt evaluation supplementation protocols higher dosages we recommend for iron, folate, calcium. Consideration also be given evaluating shorter lengths OAGB.
