Prophylactic clip application after colonoscopic polypectomy did not reduce delayed bleeding. This study found no significant difference in hemorrhage rates between clipped and unclipped ulcers, suggesting clips are not effective for preventing post-polypectomy bleeding.

Area of Science:

  • Gastroenterology
  • Endoscopic Surgery

Background:

  • Post-polypectomy hemorrhage is a common complication of colonoscopy.
  • Predicting delayed bleeding after polyp removal is challenging.
  • This study investigated prophylactic clip use to prevent bleeding.

Purpose of the Study:

  • To evaluate the efficacy of prophylactic clip application in preventing delayed bleeding after colonoscopic polypectomy.

Main Methods:

  • A randomized controlled trial compared prophylactic clip placement versus no clip in patients undergoing endoscopic mucosal resection for polyps.
  • Ulcer size averaged 7.8 mm.
  • Delayed bleeding was defined as bloody stool or hematochezia, identified by emergent colonoscopy.

Main Results:

  • Delayed bleeding occurred in 0.98% of ulcers with clips and 0.96% without clips (p > 0.9999).
  • Bleeding events happened 1-4 days post-procedure.
  • No patients required transfusion or surgery for bleeding.

Conclusions:

  • Prophylactic clip placement does not decrease the incidence of delayed bleeding after colonoscopic polypectomy.
  • The findings suggest routine prophylactic clipping may not be necessary for preventing post-polypectomy hemorrhage.
