One of the most perplexing complications of otherwise successful gastric surgery is the development of a complex of gastrointestinal and vasomotor symptoms commonly referred to as the dumping syndrome. Although not fatal, the severity of symptoms may be so great that the patient cannot lead a normal life and in some instances may be unable to continue his usual occupation. The reported incidence of the dumping syndrome following gastrectomy ranges as high as 70% or 80% in various series but is ordinarily significant in only 5% to 12% of patients. The voluminous work on the subject since its first description by Denechau in 1907 attests to its importance and the difficulty of adequate explanation of the symptom complex.
Attempts to treat such patients are frustrating for the physician and discouraging to the patient who sometimes thinks that he has traded a benign disease with a specific treatment for a disabling
