Abstract Introduction Sleeve Gastrectomy and RYGB are actually the most frequently performed bariatric procedures world-wide. OAGB is increasing in numbers, SASI bypass is a recently developed procedure, hoping with her to avoid the negative changes happening after the above-mentioned procedures. It is a malabsorptive procedure. 3 years follow up results obtained in terms of weight loss and the effect on comorbidities were compared between SASI and OAGB patients. Patients and methods We collected our data prospectively from our clinic and formed two groups (Gr) of patients, Gr A: SASI, Gr B: OAGB (no randomization). Analysed variables were baseline and post-operative BMI, excess weight loss (EWL), pre- and post-operative comorbidities up to 3 years. Results Gr A: between 2019–2023. we have performed 166 SASI operations. 144(86%) patients available for follow up. Gr B: included 142 OAGB patients, 120 patients (84%) available for follow up. There were no significant differences in age, gender, comorbidities or anthropometric measurements preoperatively between both groups. follow up of 3 years We observed mild not significant differences in EWL in favour for OAGB, Diarrhea, and post prandial abdominal pain, stool odour less bad in SASI Group. BMI post SASI decreased from 43 kg/m2 to 28 kg/m2, Post OAGB from 42.5 kg/m2 to 27 kg/m2), with EWL of 79%, and 80% respectively Diabetes Miletus type II (DM II), Hyperlipidaemia resolved in similar percentage in both groups. Iron deficiency anaemia and hypoalbuminemia incidence were higher in Gr B. Conclusion SASI Bypass achieve superior results in terms of quality of life and comorbidity and results with significant and comparable EWL to OAGB after 3 years FU.
