What is Transit (Gastric) Bipartition?

Transit bipartition surgery is a modified form of ”Duodenal Switch + Biliopancreatic Diversion” surgery which has been described and accepted many years ago. The aim of this surgery is to ensure that 1/3 of the food passing through the stomach is passed through the normal anatomical path of the duodenum and 2/3 of the small intestine that is oralized into the stomach and the lower half of the intestine. In this way, the upper parts of the small intestines, which have negative effects on blood sugar regulation and feeling of hunger, are disabled in such a way as to impair the absorption of vitamins and minerals as least as possible, as well as increasing the positive effects of regulating the blood sugar of the small intestines and the feeling of long-term satiety.

How is it performed?

Like all obesity and metabolic surgical procedures performed today, this operation is performed by laparoscopic method. Transit bipartition surgery requires more laparoscopic surgery experience, skills and experience compared to sleeve gastrectomy.

Effect mechanism on weight and metabolic balance

Transit bipartition surgery is effective in the regulation of weight loss and metabolic syndrome by multiple mechanisms. The tube stomach, which is a part of surgery, plays an important role in this effect. As a result of tube stomach surgery, patients lose weight because they can eat less food and not feel as much hunger as they used to. Mouthing of the lower part of the small intestine to the exit of the stomach allows the food to come into direct contact with the lower part of the small intestine without being over-digested. increases the 

secretion of intestinal hormones. This effect plays an important role in weight loss and blood sugar control. Another effect of transit bipartition surgery that provides weight loss is that it causes absorption disorder that does not require lifelong vitamin and mineral supplements. The theory that only 1/3 of eaten foods pass through the small intestine through the duodenum, considerably reduces the negative impact of the upper small intestine on blood sugar and hunger feeling without creating deficiencies in the vitamins and minerals absorbed in this area.

Pros:

o Leakage probability is low (the risk of leakage is reduced because the pressure in the formed tube stomach will be lower due to the presence of a second outlet in the stomach).

o Treatment is easier and shorter when leakage develops (due to low pressure for stomach) o Weight loss and metabolic effects are high

o It does not require lifelong vitamin-mineral supplementation while it causes absorption disorder and causes weight loss to occur more.

Suitable for:

o Transit bipartition surgery is a surgery that has both weight loss and hormonal effects; o Only to provide effective and permanent weight loss in individuals suffering from excess weight

o Obtaining weight loss and metabolic effect in obese patients with both excess weight and metabolic syndrome findings

o It is a method that can be applied to patients who have pancreatic reserve problems (having limited amount of insulin hormone in the pancreas) but who have excess weight (BMI: 28-30) or stage-1 obesity (Body Mass Index: 30-35).
