This study has been restricted to the role of the small intestine in the etiology of chronic abdominal disorders and to the considerations that must be given it in the diagnosis of chronic digestive complaints.
Clinical signs and symptoms of disorders of the small intestine arise as a result of interference with the physiologic functions of digestion, absorption and motility.
SYMPTOMATOLOGY OF DISEASE OF SMALL INTESTINE
There are few symptoms which are highly diagnostic of disease of the small intestine. Obstructive lesions may cause vague prodromal symptoms such as a sense of fulness or cramplike pain after meals, but the almost completely fluid nature of the content of the small intestine makes for an "all or none" type of obstruction. There is no obstruction until suddenly there is complete obstruction with an acute onset of symptoms that are either persistent or intermittent, depending on the mechanical status of the point
