Transit Bipartition Surgery
It is an advanced metabolic surgery method preferred in the treatment of Type 2 diabetes, regardless of obesity.
The aim of this surgery is to reduce the stomach volume with sleeve gastrectomy, and to eliminate the desire to eat by stopping the secretion of the hunger hormone Ghrelin. In addition, the hormones we call Incretin (GLP-1, Oxyntomodulin, PYY), which regulate the secretion of insulin from the pancreas, are secreted from the part of the small intestine called the ileum, which is close to the large intestine. Therefore, in order to secrete these hormones that improve insulin resistance, the ileum must be faced with the undigested food beforehand. For this purpose, after measuring a certain length backwards from the junction of the ileum with the large intestine, an anastomosis is made to the lower part of the stomach. The aim is to reduce both absorption and improve insulin resistance by increasing Incretin release. Since the absorption is very little impaired, the side effects related to the digestive system are very limited.
As a result, small intestine hormones which stimulate beta cells of pancreas are stimulated and diabetes is controlled.
Transit bipartition technique:
During the laparoscopic method, small incisions are made in the abdomen first. The recovery process is faster after the operation performed with the closed technique. First of all, gastric sleeve surgery is performed. Then, measuring 250 cm from the ileocolic junction of the small intestine, the small intestine is cut into two from the marked part. The cut distal part of the small intestine is anastomosed to the reduced stomach. The proximal loop is joined to the last 100-150 cm of the ileum from the ileocolic junction. The purpose of transit bipartition surgery is to provide drug-free diabetes control, especially in Type 2 diabetes patients with a BMI of 30 and above. Thus, on the one hand, sugar control is ensured, on the other hand, normal duodenum anatomy and structure are preserved.
What are the Consequences of Transit Bipartition?
With transit bipartition surgery, the intragastric pressure is significantly reduced. Since the intralumenal pressure is low, leakages are reduced. Nearly 90 percent of appropriately selected Type 2 diabetes patients discontinue the treatment after surgery, and the remainder can be controlled only with oral antidiabetic drugs. Transit bipartition is a very effective surgery that can lead to rapid, effective and permanent weight loss as well as significant improvement in metabolic diseases.
