Transit Bipartition surgery is a metabolic surgical method developed for the treatment of Type 2 diabetes and provides weight loss for obese patients with a BMI above 30.
What is Transit Bipartition Surgery?
Transit Bipartition surgery is a metabolic surgical method developed for the treatment of Type 2 diabetes and provides weight loss for obese patients with a BMI above 30. The surgery consists of connecting the 1/3 end of the small intestine to the stomach. The part of the small intestine connected to the stomach is where the small intestine and large intestine meet. Therefore, the nutrients passing through it stimulate small intestine hormones to control diabetes. The surgery is performed laparoscopically under general anesthesia as in other obesity surgeries such as gastric bypass and gastric tube surgeries.
Transit bipartition is a surgical model developed to offset increased consumption of high glycemic index foods.
Who Are the Ideal Candidates?
The patient with diabetes Type 2 is an ideal candidate for this metabolic surgery. However, although this surgery is a weight loss procedure, an overweight patient with a body mass index of 30-35 and who does not have any medical conditions such as vitamin deficiency or diabetes should first consider sleeve gastrectomy surgery.
Meanwhile, a BMI value above 45 qualifies for transit bipartition surgery, even if the patient does not have diabetes or any vitamin deficiency.
Surgery Technique in 3 Steps
The first part of the surgery is sleeve gastrectomy surgery, which consists of removing 75% of the stomach and reducing the capacity of the stomach to 25%. The main purpose and motive behind this part is to get rid of the part that contains the hunger hormones. In this way, the secretion of hunger hormone is also eliminated.
The second part of the operation consists of determining the intersection of the small intestine and the large intestine and then integrating this intersection directly with the stomach. The purpose behind this procedure is to greatly increase the secretion of hormones that will aid in the digestion of food intake and absorption of vitamins, minerals and other nutrients.
The last part of the operation is the anastomosis of the duodenum. This is done to reduce the secretion of GIP hormone because the host for this secretion is the duodenum. GIP (Glucagon-like peptide) stimulates insulin secretion.
Although the surgery may seem like a very complex procedure when explained scientifically, it is a simple and algorithmic surgery that functions as both diabetes repair and weight loss surgery.
