[Role of changes in the hormonal system of the gastrointestinal tract after vagotomy]

The level of gastrin, serotonin, insulin and cortisol in the blood was raised after different types of vagotomy. Raised hormone secretion depends on the time following operation, the severity of a pathological process, to a lesser degree, on the type of surgical intervention and nature of postvagotomic disturbance. Shifts in the hormonal apparatus are caused by operation and associated with it functional-morphological changes of the digestive organs, the preservation of preoperative changes and developing compensatory-adaptive reactions. An excess of intestinal hormone secretion in the postoperative period can be responsible for the development of pathological disorders, in particular the dumping syndrome.
