A New Paradigm Shift in Gastroparesis Management

Area of Science:

• Gastroenterology
• Physiology
• Medical Technology

Background:

• Gastroparesis, previously considered rare, is increasingly recognized.
• Advances in the 2010s have reshaped understanding and management.
• Rising prevalence linked to better diagnostics and past underdiagnosis.

Purpose of the Study:

• Review major breakthroughs in gastroparesis research and clinical practice.
• Highlight advancements in understanding the pathophysiology of gastroparesis.
• Discuss novel diagnostic and therapeutic strategies for gastroparesis.

Main Methods:

• Review of scientific literature on gastroparesis.
• Analysis of recent discoveries in gastric physiology.
• Evaluation of new diagnostic and therapeutic technologies.

Main Results:

• Gastric pacemaker unit redefined to include smooth muscle cells, interstitial cells of Cajal, and PDGFRα+ cells.
• Validated point-of-care diagnostics developed: wireless motility capsule, C13-breath test, impedance planimetry.
• Novel minimally invasive treatments introduced: new pharmacologic agents, gastric peroral endoscopic pyloromyotomy.

Conclusions:

• Significant progress in understanding gastroparesis pathophysiology.
• Improved diagnostic accuracy and accessibility.
• Emergence of effective, less invasive therapeutic options.
