IBC Oxford University Poster Abstract 6 - The nutritional effect of SASI: a 5—years’ experience

Abstract Introduction Since the introduction of Single anastomosis Sleeve ileal Bipartition (SASI) many studies have focused on the nutritional malnutrition effect of SASI. Although there is still no consensus on whether SASI causes malnutrition, many studies have disagreed with such claims. In this study, we focused on re-evaluating the malnutritional effects of SASI using the same methodology in the short-term outcome. Methods 147 cases of SASI were recruited retrospectively from 2018 to 2023 with a 2-year follow-up period. All cases had undergone periodical follow-ups for Cholesterol, LDL, HDL, TG, Serum iron, Ferritin, Calcium, Vitamin D3, and Vitamin B12. Results Postoperative Lipid profile significantly reduced (P ≤ 0.001). However, there was no significant reduction in serum iron (P = 0.387), Ferritin (P = 0.061), and serum calcium (P = 0.091). with postoperative supplementation, there was a significant reduction in, Vitamin D3 (P ≤ 0.001), and Vitamin B12 (P ≤ 0.001). Conclusion Although there is a rising concern for malnutrition with SASI, unification of the SASI technique, and the usage of the correct postoperative supplementation with regular follow-ups does avoid malnutrition.
