Loop Bipartition Surgery
Loop Bipartition Surgery is one of the most successful operations in the treatment of diabetes. The most important feature of this success while providing the same purpose compared to other operations performed is in protection of the natural digestive function to a great extent. It also known as Single Anastomosis Sleeve Ileal (SASI) Bypass.
Loop bipartition surgery is consisted of two steps.
- The first step is to perform a sleeve gastrectomy which is slightly larger than the standard one.
- The second step is creating a passing over bridge (bypass-anastomosis) from the antrum section at the bottom of the stomach towards the small intestine.
The connecting level from the stomach to the intestine is usually 2.5-3 meters proximal part of the small intestine-large intestine junction (ileocecal valve). Thus, having a tube stomach restricts intake of nutrients, facilitates saturation and weight loss and at same bypass surgeries with its outcome effect increase the activation of the small intestine hormone (incretin) in favour to metabolism regulation. It is a simple, low-risk operation design with successful results performing single cross-over (anastomosis). In this case, 1/3 of the food and 2/3 of the natural way pass through the new way. Approximate weight loss of patients is around 70-75%. With this operation, successful results were obtained on diabetes. On average, the effect on DM is 86%. Vitamin and mineral supplements are less needed in patients than in other bypass operations.
