Understand the procedure

What is SASI Bypass?

SASI or loop bipartition combines sleeve gastrectomy with a connection between the stomach and distal small intestine. Food can continue through the duodenum while part passes through the new metabolic pathway.

Single-anastomosis sleeve ileal bypass preserves the normal route while adding a second pathway to the distal small intestine. It is an advanced option requiring careful metabolic and nutritional selection.

Individual selection

Who may be considered?

BMI alone does not select a treatment. Medical history, metabolic health, reflux, previous procedures, nutrition and capacity for long-term follow-up are considered together.

Severe obesity with important metabolic disease

Selected people requiring a stronger option than sleeve alone

Patients able to maintain intensive nutrition monitoring

Occasional revision pathways after specialist review

Clinical safety:

A first screening step

Calculate BMI—then decide with the team.

BMI is only one part of assessment. Procedure choice also depends on medical history, related conditions, anatomy, nutrition and individual risks.

Your result—

Enter your height and weight for a screening BMI estimate.

BMI is a screening measure, not a diagnosis or a decision about surgery. Medical history, related conditions, nutrition, previous weight-management attempts and surgeon assessment are also required.
