Randomization is not the (only) answer: a plea for structured objective evaluation of endoscopic therapy.

Area of Science:

• Gastroenterology and Endoscopy
• Clinical Trial Design
• Evidence-Based Medicine

Background:

• Endoscopic therapy is established for conditions like dysphagia, jaundice, bleeding, and polyps.
• The role of endoscopy in managing chronic pancreatitis remains uncertain.
• Randomized controlled trials (RCTs) are the gold standard for evaluating therapies but face challenges in endoscopic research.

Discussion:

• Difficulties in conducting meaningful RCTs for endoscopic methods limit practical answers.
• Stringent observational studies can provide valuable evidence when RCTs are impractical.
• Defining data elements and involving independent arbiters are crucial for robust observational studies.

Key Insights:

• Endoscopy's role is clear in some areas but debated in others.
• RCTs for endoscopic interventions are often difficult to execute effectively.
• High-quality observational data can be a reliable alternative for clinical guidance.

Outlook:

• Future research should explore alternative methodologies beyond traditional RCTs.
• Standardized, rigorous observational studies can enhance evidence for endoscopic practice.
• Improved data collection and independent review are key to advancing endoscopic evidence.
