Fistula Intestinal Complete

**Fistula** is a pathological anastomosis between two hollow organs, for example, the trachea and the esophagus or the jejunum and the rectum.

Fistulas that are not associated with the human respiratory or digestive system are called traumatic. They are also called spontaneous and are classified as developmental defects. We are talking about the formation of a cavity at the junction of internal organs. A tracheoesophageal fistula is formed as a result of trauma. It connects these hollow structures together. At the same time, the outer wall of the trachea continues to develop, and the inner membrane of the trachea closes with the lumen of the esophagus. This creates a closed bubble. The formation of a channel through the inner surface of the esophagus after surgery contributes to the formation of a fistula.

Anastomosis of the intestinal organs can also cause the formation of a fistula in the abdominal cavity. Incorrect formation of the child’s intrauterine systems leads to abnormalities. The rudiment does not have the ability for further differentiation. The fetus does not have a pancreas. Parts of the pancreas are replaced by the intestines. Violation of the development of differentiations in utero leads to disruption of embryogenesis. The anastomosis of the head of the pancreas with the duodenum forms a gastroenteroanastomosis fistula. The consequence of the presence of an anomaly is intussusception - parts of the intestine are embedded in each other.
