 This is a randomized, double-blind, placebo controlled, crossover study of the effect of 100μg octreotide SC on ad libitum food intake in patients free from complications or recurrence at least one year post-oesophagectomy, gastrectomy or pancreaticoduodenectomy. A comparator group of age, weight and gender matched subjects will be studied concurrently, and caloric intake and subjective symptom scores after administration of octreotide versus placebo among surgical and comparator subjects will be assessed.
