Gastroparesis: pathogenesis, diagnosis and management.

Area of Science:

• Gastroenterology
• Digestive Diseases
• Motility Disorders

Background:

• Gastroparesis is a common disorder characterized by delayed gastric emptying without physical obstruction.
• Its primary causes include idiopathic, diabetic, and postsurgical conditions, alongside autoimmune, neurologic, and paraneoplastic factors.
• Histological findings in severe cases show inconsistent neural, muscular, and interstitial cell defects, with elevated inflammation.

Purpose of the Study:

• To review the current understanding of gastroparesis, encompassing its etiologies, diagnostic methods, and therapeutic strategies.
• To highlight the limitations in current treatment efficacy and the need for controlled studies.
• To emphasize the ongoing research efforts aimed at improving patient outcomes.

Main Methods:

• Review of existing literature on gastroparesis.
• Analysis of diagnostic modalities including gastric emptying scintigraphy, wireless motility capsules, and breath tests.
• Examination of current treatment approaches, including dietary changes, medications, and surgical interventions.

Main Results:

• Gastroparesis presents with heterogeneous etiologies and histological findings.
• Diagnostic tools like scintigraphy are standard, with newer methods offering alternatives.
• A wide array of treatments exist, but most lack rigorous controlled testing.
• The natural history and long-term outcomes remain poorly understood.

Conclusions:

• Gastroparesis is a complex condition with diverse causes and poorly understood natural history.
• Current diagnostic and therapeutic strategies require further validation through controlled research.
• Ongoing research is crucial for advancing the understanding and management of gastroparesis.
