Unsedated colonoscopy: A neverending story

Area of Science:

• Gastroenterology
• Medical Practice Variation

Background:

• Sedation and analgesia are standard for colonoscopy in Western countries.
• Unsedated colonoscopy is common in Europe and the Far East due to cultural differences.
• Patient and endoscopist attitudes influence sedation practices.

Purpose of the Study:

• To explore the feasibility and acceptance of unsedated colonoscopy.
• To highlight variations in colonoscopy sedation practices globally.
• To review alternative techniques for improving unsedated colonoscopy.

Main Methods:

• Literature review of studies on colonoscopy sedation practices.
• Analysis of data comparing sedated and unsedated colonoscopy.
• Examination of alternative techniques like water irrigation and CO2 insufflation.

Main Results:

• Unsedated colonoscopy is routinely performed in specific regions.
• Cultural factors significantly impact sedation preferences.
• Techniques such as warm water irrigation and CO2 insufflation enhance quality and tolerance.

Conclusions:

• Colonoscopy can be performed effectively without sedation.
• Alternative insufflation methods improve patient experience.
• Cultural context is crucial in determining colonoscopy sedation protocols.
