In the early 50s, some authors had already described the effects of catecholamines on the intestine, by the continuous infusion of noradrenaline into rabbits causing significant dilation of their colon. Most of the time, high levels of circulating catecholamines in secreting pheochromocytomas, can disturb the intestinal function giving a protean clinical presentation of the pheochromocytomas. As a result of these catecholamines, their morbidity and mortality are mainly of cardiovascular origin, but digestive morbidity and mortality is also significant due to severe cases of complete intestinal paralysis mediated by catecholamines, which can lead to extreme digestive pictures.
