RESUMO
BACKGROUND: Sparse data are available regarding the efficacy and safety of single anastomosis sleeve ileal (SASI) bypass surgery, where most available studies utilized short-term follow-ups. Therefore, this study was conducted to evaluate the safety and outcomes of this procedure in three consecutive years after the surgery. MATERIALS AND METHODS: This retrospective study was carried out with 116 patients who underwent SASI from October 2016 to September 2021. Anthropometric, clinical, and biochemical data were recorded before, 1, 2, and 3 years after surgery. RESULTS: The 1, 2, and 3-year percentage of excess weight loss (%EWL) were 87.37%, 90.7%, and 80.6%, respectively. Remission or improvement was recorded for diabetes mellitus in 90.9%, hypertension in 80.0%, hyperlipidemia in 100%, sleep apnea in 100%, and irregular menstruation in 58.06 at 3 years after surgery. No mortality and 5.1% early major postoperative complications were recorded. Eight patients (6.8%) had reversal surgery due to EWL > 100%. CONCLUSIONS: The SASI bypass is an effective bariatric surgery that achieved sequential weight loss and improvement in medical comorbidities three years after the surgery; however, standardization of SASI procedure technique is needed to ameliorate nutritional deficiencies.
