Evaluation and Classification of Gastroparesis
Gastroparesis is a chronic and often debilitating disorder of the stomach characterized by delayed emptying without mechanical obstruction. It is an underrecognized and often undertreated disease often presenting with nausea, vomiting, bloating, and/or abdominal pain. The pathophysiology involves derangements of normal gastric motor function. The most common etiologies include idiopathic, diabetes, and postsurgical. In approximately one-half of gastroparetics, there is no identifiable cause. After ruling out mechanical obstruction with cross-sectional imaging and endoscopy, the diagnosis of gastroparesis is made with gastric emptying scintigraphy. This is a noninvasive and quantitative measurement of gastric emptying and is considered the gold standard for diagnosis. In this chapter we discuss the evaluation, workup, and classification of gastroparesis.
