National survey of physicians' perception of the cause, complications, and management of gastroparesis.

Objectives: Manifestations of gastroparesis are heterogeneous and clinical complications are poorly defined. Misconceptions of gastroparesis may be common. The objective was to determine physicians' perception of gastroparesis and identify areas that need further research and education.

A novel classification scheme for gastroparesis based on predominant-symptom presentation.

Aim: Symptoms of gastroparesis are very diverse. Classifying patients by predominant symptom may improve management strategy.

Goal: To validate a new symptom-predominant classification for gastroparesis using symptom severity and quality-of-life measures.
