Retroflexion is a valuable technique for removing large sessile colon polyps, especially those located proximally. This endoscopic method increases the number of polyps suitable for resection without complications.

Area of Science:

  • Gastroenterology
  • Endoscopic Surgery

Background:

  • Limited literature exists on the efficacy of retroflexion for large sessile colon polyp removal.
  • Sessile polyps, particularly those proximal to the rectum, pose challenges for endoscopic resection.

Purpose of the Study:

  • To evaluate the utility and effectiveness of retroflexion in the endoscopic resection of large sessile colon polyps.
  • To determine if retroflexion enhances the success rate of polyp removal in difficult-to-access locations.

Main Methods:

  • Retrospective analysis of consecutive cases undergoing endoscopic resection of sessile colon polyps (≥ 2 cm).
  • Utilized prototype colonoscopes with short bending sections for polyp removal.
  • Intervention involved endoscopic resection of 59 proximal sessile colon polyps.

Main Results:

  • Retroflexion was used in the removal of 14 polyps (4 entirely, 10 partially).
  • Patients with retroflexion-assisted removal were more likely to be referrals (p=0.05).
  • No perforations or complications were associated with the use of retroflexion.

Conclusions:

  • Retroflexion serves as a beneficial adjunctive procedure for endoscopic resection of select proximal sessile colon polyps.
  • The technique expands the spectrum of colon polyps amenable to endoscopic removal, particularly those challenging to access.
  • Further research may be warranted, acknowledging the retrospective nature and specialized equipment used.
