Abstract

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.
