Transit bipartition surgery is a both restrictive and malabsorptive surgical method introduced in medical literature by Dr. Santoro. The most distinguished feature of this method compared to other bypass methods is that normal anatomic food pathway is not disrupted and some of the nutrients still pass through normal anatomic pathway to intestines. This leads to less vitamin and mineral deficiency in patients.
Technically, during the first part of the surgery, classic gastrectomy is performed and then in the second part of the surgery, approximately 250 cm starting from large intestines to small intestines are bypassed and anastomosed to the lower stomach. The rest of the intestines is anastomosed to small intestines approximately 100 cm before from large intestines. So there is no actual removal of intestines. This operation allows 1/3 of the nutrients pass through the normal pathway and the rest uses the new pathway created.
Transit bipartition operation is accepted as a superior method compared to other gastrectomy methods for Type II Diabetes management in patients with enough pancreas reserve. The method is mostly suitable for patients for whom diabetes is the main problem. It is restricted to opt for this method for bariatric purposes.
5 year results were published in 2012 for this method. It can be safely preferred for surgical treatment of Type II Diabetes. If the patient follows all the treatment protocols carefully, they will not experience vitamin deficiency by 90%. One of the important advantages of the method is rare encounter of gastrointestinal leak often seen in gastrectomy methods as the stomach has two exits. Another important advantage is that each point of the stomach and duodenum can be seen endoscopically.
5-year results of this surgical method reveals that patients have lost 74% of their excess weight and 86% of them could control their blood glucose values without medication.
