BS O04 - Audit of outcome of SADIS- Results from a single Bariatric center

Abstract Background SADIS- Single anastomosis Duodeno-ileal switch is a bariatric procedure that has been accepted widely as a bariatric procedure. Literature has shown that it gives good outcomes in terms of weight loss and resolutions of obesity related morbidity. There has been criticism about the nutritional deficiencies associated with SADIS. It is a technically challenging procedure, so it is not extremely popular in the bariatric world where sleeve is the most done procedure and RYGB is the gold standard. Method All the patients at our centre undergo MDT assessment. Based on the MDT discussion and the patient preference, the decision of surgery is made. All the patients who underwent SADIS were included in the study Primary aim: Weight loss at 6 months, 1 year, 2 years and 6-10 years ORM resolution at 6 months, 1 year, 2 years and 6-10 years Nutritional deficiencies in the short term and long term. Results 17 patients underwent SADIS. Average BMI 55, it is higher than the usual BMI cohort, saying that higher BMI patients were offered SADIS as compared to the lower BMIs, who were offered Sleeve, Bypass. The weight loss pattern followed by SADIS patients was more than bypass patients over 6 m, 1 y and 2 y. The SADIS patients had better sustained weightloss over 6-10 y. One crucial factor in patient profile is the ratio of psychological vs physiological co-morbidities is higher than the average; which corresponds to our findings of the feasibility study for bariatric surgery for BMI >65 Conclusion SADIS gives good outcomes in terms of weight loss and resolution of co-morbidities. Long term results with SADI in terms of sustained weight loss are better than bypass. It did not lead to increased nutritional deficiencies.
