Idiopathic Gastroparesis Registry Using a Predominant-Symptom Classification

Gastroparesis Clinical Trial

Official title: Idiopathic Gastroparesis Registry to Define Severity, Treatment Response, and Prognosis Using a Predominant-Symptom Classification

Status Terminated

Clinical Trial Summary

The diagnosis of "gastroparesis" suggests that delayed gastric emptying is the underlying cause of symptoms, but this description fails to explain the variable presentation. There are fundamental differences in causes, symptoms, and prognosis among patients with idiopathic gastroparesis. Understanding these differences is necessary in order to provide effective treatment in these patients. We believe our classification for gastroparesis is a useful tool in the management of patients with idiopathic gastroparesis to predict clinical severity, treatment response, and future prognosis.

Clinical Trial Description

"Idiopathic gastroparesis" is a poor term to describe this very heterogeneous syndrome. Pathophysiology may not be "idiopathic," but merely unidentifiable with conventional methods suggested for gastroparesis. The diagnosis of "gastroparesis" suggests that delayed gastric emptying is the underlying cause of symptoms, but this description fails to explain the variable presentation. There are fundamental differences in pathophysiology, clinical presentation, severity, and future prognosis among patients with idiopathic gastroparesis. Understanding these differences is necessary in order to provide cost-effective treatment in these patients.

We believe our clinical classification for gastroparesis is a clinical useful tool in the management of patients with idiopathic gastroparesis to predict clinical severity, treatment response, and future prognosis. Patients with vomiting-predominant gastroparesis will be more likely to have an underlying cause, such as viral infection or impaired glucose tolerance with vagal neuropathy. Their symptoms will likely be persistent. Patients with dyspepsia-predominant gastroparesis mimic those with functional dyspepsia and are unlikely to have complications such as weight loss, and dehydration. The necessity of enteric feeding in these patients is also unlikely. Prokinetics may help since delayed gastric emptying may contribute to epigastric pain or postprandial distress. Finding and treating small intestinal bacterial overgrowth as well as suggesting lifestyle and dietary modifications may be helpful. Patients with regurgitation-predominant gastroparesis may benefit most by improving their delayed gastric emptying. Their gastroparesis may cause reflux-like symptoms, especially at night. ;
