Systemic sclerosis (SSc) frequently causes gastric electrical dysfunction, detected by electrogastrography (EGG), and delayed gastric emptying. EGG and gastric emptying tests help identify gastroparesis in SSc patients.

Area of Science:

  • Gastroenterology
  • Rheumatology
  • Medical Physiology

Background:

  • Systemic sclerosis (SSc) is a multisystem autoimmune disease that can affect gastrointestinal motility.
  • Gastric dysfunction, including electrical activity and emptying abnormalities, is a common complication in SSc patients.

Purpose of the Study:

  • To determine the prevalence of gastric electrical activity dysfunction using electrogastrography (EGG), gastric emptying disturbances, and endoscopic findings in SSc patients.
  • To explore associations between EGG and gastric emptying data with clinical manifestations and esophageal motor function.

Main Methods:

  • Fasting and postprandial electrogastrography (EGG) were performed on 22 SSc patients and 22 healthy controls.
  • Gastric emptying was assessed using radiopaque pellets, and gastroscopy was conducted in SSc patients.

Main Results:

  • EGG disturbances were found in 81.82% of SSc patients, characterized by increased fasting bradygastria and reduced postprandial electrical power.
  • Delayed gastric emptying was observed in 11 SSc patients, and 3 had "watermelon stomach" (gastric antral vascular ectasia).
  • No significant correlation was found between gastric impairment severity and clinical SSc features or esophageal dysfunction.

Conclusions:

  • EGG is a valuable noninvasive tool for early detection of gastric electrical activity disorders in SSc.
  • EGG and gastric emptying studies can help identify symptomatic SSc patients with gastroparesis.
  • Watermelon stomach should be considered in SSc patients with gastrointestinal bleeding or iron deficiency anemia.
