[Workup and treatment of gastroparesis].

Gastroparesis is defined as impaired gastric emptying without mechanical obstruction and cardinal symptoms including vomiting, nausea, early satiety, and upper abdominal pain. Most cases of gastroparesis are diabetic, idiopathic or post-operative. The correlation between symptoms and objective measures of gastroparesis is poor. Basic treatment includes dietary advices and prokinetics. Selected patients not responding to basic treatment can be offered gastric electrical stimulation. In many cases, gastroparesis is present in combination with other motility disorders, especially constipation.
