Abstract

Abstract:

Objective

To investigate the clinical safety and feasibility of single-incision laparoscopic sleeve gastrectomy combined with single-anastomosis stomach-ileal bypass (SILSG-SASI) in patients with moderate obesity and metabolic syndrome.

Methods

We report the clinical practice of a 39-year-old male patient with moderate obesity and severe metabolic dysfunction who underwent SILSG-SASI treatment.

Results

The surgical procedure was completed successfully without the need for additional trocar placement or conversion to open surgery. No serious perioperative complications occurred. The patient achieved a favorable recovery and was discharged on the third postoperative day. Short-term follow-up confirmed significant weight loss and marked improvement in metabolic parameters, including blood glucose and lipid profiles.

Conclusion

For patients with moderate obesity, the SILSG-SASI procedure is technically feasible and offers perioperative safety benefits. Short-term follow-up results demonstrate effective weight reduction and metabolic improvement.
