Will purposely seeking detect more colorectal polyps than routine performing during colonoscopy?

Area of Science:

• Gastroenterology
• Endoscopy
• Colorectal Cancer Screening

Background:

• Intraoperative polyp detection often exceeds preoperative findings during colonoscopic polypectomy.
• A discrepancy exists between polyps found during routine examination versus those purposefully sought.

Purpose of the Study:

• To evaluate if actively seeking polyps during colonoscopy improves detection rates compared to routine examination.
• To determine if a targeted polyp search yields more polyps than standard colonoscopy procedures.

Main Methods:

• Patients undergoing colonoscopy were randomized into two groups: Group A (purposely seeking polyps) and Group B (routine examination).
• Polyp detection rate (PDR) and partial polyp miss rate (PPMR) were calculated for all cases and specific polypectomy subgroups.
• Data were analyzed comparing polyp detection between the two groups and across different colonoscopy sessions.

Main Results:

• No significant difference in polyp detection rate (PDR) was observed between the group that purposely sought polyps and the group that underwent routine examination.
• Partial polyp miss rate (PPMR) showed no significant difference between groups during the first colonoscopy.
• PPMR was higher in the first colonoscopy subgroup compared to the second colonoscopy subgroup within both the purposely seeking and routine examination groups.

Conclusions:

• Actively seeking colorectal polyps during colonoscopy does not lead to a higher number of detected polyps compared to routine colonoscopic examination.
• The findings suggest that routine colonoscopy is as effective as a dedicated polyp search in detecting colorectal polyps.
