Upper gastrointestinal endoscopy in normal asymptomatic volunteers

Area of Science:

• Gastroenterology
• Internal Medicine
• Clinical Research

Background:

• Asymptomatic individuals are often presumed to have a healthy upper gastrointestinal tract.
• Screening endoscopy is typically reserved for symptomatic patients or specific risk factors.

Purpose of the Study:

• To determine the prevalence of upper gastrointestinal abnormalities in asymptomatic male volunteers.
• To identify common endoscopic findings in a healthy, young male population.

Main Methods:

• Prospective study involving 355 healthy male volunteers aged 18-45.
• Esophagogastroduodenoscopy screening was performed prior to clinical trial admission.
• Abnormal findings were documented by location and grade of lesion.

Main Results:

• 134 volunteers (38%) presented with abnormal endoscopic findings.
• Stomach involvement was observed in 24%, duodenum in 20%, and esophagus in 14%.
• Prevalence rates included erosive esophagitis (8.5%), erosive gastritis (12%), erosive duodenitis (10%), gastric ulcer (2%), and duodenal ulcer (2%).

Conclusions:

• A substantial proportion of asymptomatic young men harbor upper gastrointestinal abnormalities.
• These findings suggest a higher prevalence of subclinical gastrointestinal pathology than previously recognized.
• Routine endoscopic screening in asymptomatic populations may reveal significant pathology.
