Ileal Interposition

Ileal interposition is a bariatric surgical procedure that is usually applied to type-2 diabetes patients who do not have serious weight problems. This technique was introduced by a Brazilian surgeon in the late 90s. The ileum is the name of the last part of the small intestine. Ileal interposition is applied in two different ways. The first one is the placement of the ileum between the stomach and the beginning of the small intestine. The second method is to place the ileum only at the beginning of the small intestine without touching the stomach.

Ileal Interposition: Procedures

There are 2 different procedures in ileal interposition surgery: Duodenal-ileal interposition: In this procedure, the stomach and duodenum are closed from the second part of the duodenum. The last 30 cm of the small intestine is preserved, and a 170 cm part is connected to the first part of the duodenum at the end of the stomach. The other end is connected to the beginning of the small intestine, so it is interposed. In this procedure, since the duodenum and the initial parts of the small intestine are disabled, it is also a partly bypass operation. Significant blood sugar and weight control are observed in patients undergoing this method. Jejuno-ileal interposition: In this procedure, the last 30 cm of the small intestine is protected and a 200 cm segment is prepared from the last part to be interposed. In this method, food can pass through the small intestine without interruption. The duodenum is also active and the patient does not have any absorption problems. Its effect on blood sugar is more limited also.

Ileal Interposition: Candidates?

Patients who are candidates for ileal interposition surgery are generally seen with type-2 diabetes. Patients whose blood sugar cannot be checked despite treatment and whose organs are damaged may be candidates. The operation may not be applied to people with a body mass index below a certain level.
