Improving quality measures in colonoscopy and its therapeutic intervention

Area of Science:

• Gastroenterology
• Endoscopy
• Colorectal Cancer Prevention

Background:

• Colonoscopy with polypectomy is crucial for reducing colorectal cancer risk.
• Endoscopist performance is the primary factor influencing colonoscopy quality and polyp detection rates.
• Effective polyp removal impacts screening guidelines and reduces interval cancers.

Purpose of the Study:

• To review advancements in colonoscopy techniques for improved polyp detection.
• To discuss various endoscopic polypectomy methods and their indications.
• To summarize current knowledge on quality improvement and therapeutic interventions in colonoscopy.

Main Methods:

• Review of current literature on colonoscopy quality measures.
• Analysis of advanced colonoscopy techniques (HD, hood-assisted, chromoendoscopy).
• Evaluation of endoscopic polypectomy techniques (forceps, snare, EMR, ESD).

Main Results:

• High-definition, hood-assisted, and dye-based chromoendoscopy enhance detection of small/flat polyps.
• Virtual chromoendoscopy shows potential for polyp pathology prediction but not improved detection.
• Various endoscopic polypectomy techniques are available, chosen based on polyp characteristics.

Conclusions:

• Endoscopist skill remains paramount for high-quality colonoscopy.
• Technological advancements improve polyp detection and removal, aiding cancer prevention.
• Colonoscopy offers diverse therapeutic interventions beyond polyp removal, including bleeding control and obstruction management.
