Transit Bipartition Surgery
This advanced surgical technique combines a sleeve gastrectomy with a unique modification of intestinal transit to enhance weight loss and metabolic benefits.
How It Works
Unlike other similar procedures, this surgery creates a second outlet by connecting the distal part of the small intestine directly to the lower stomach. This allows food to pass through both pathways of the digestive system:
Approximately 1/3 of food follows the natural route through the duodenum.
The remaining 2/3 bypasses the upper small intestine and moves directly to the last portion, enhancing metabolic effects.
Who Is a Candidate?
✔️ Type 2 Diabetes: This procedure is specifically designed for patients with type 2 diabetes and is not suitable for type 1 diabetes.
✔️ Adequate Insulin Production: Patients must have sufficient insulin reserves. If insulin production is absent or nearly depleted, the surgery is not viable.
✔️ Body Mass Index (BMI): Candidates must have a BMI of 35 or higher to ensure the procedure’s effectiveness.
✔️ Good Overall Health: Patients must meet minimum heart and lung function criteria to safely undergo surgery.
Available Techniques

Why Consider This Surgery?
This innovative approach helps patients achieve significant weight loss, improved metabolic health, and better diabetes control, making it a powerful option for those struggling with obesity and related conditions.
