Endoscopic polypectomy using an endoloop may reduce bleeding risks for large colorectal polyps. However, technical challenges like narrow lumens or thin stalks can lead to failure.

Area of Science:

  • Gastroenterology
  • Endoscopic Surgery

Background:

  • Endoscopic polypectomy is standard for large colorectal polyps.
  • Bleeding is a risk after polypectomy, especially for large polyps.
  • Endoloop ligation of the polyp stalk is a technique to minimize bleeding.

Purpose of the Study:

  • To evaluate the safety and efficacy of endoloop-assisted polypectomy for large pedunculated colorectal polyps.
  • To identify factors associated with unsuccessful endoloop application.

Main Methods:

  • Retrospective evaluation of 33 patients undergoing attempted endoloop endoscopic polypectomy.
  • Inclusion criteria: large pedunculated polyps.

Main Results:

  • Endoloop application was impossible in 4 patients; snare entanglement occurred in 1.

  • Successful endoloop-assisted polypectomy was performed in 28 patients.
  • Bleeding occurred in 4 patients due to loop slippage or transection of thin stalks (< or = 4 mm).

    • Conclusions:

    • Endoloop-assisted colonoscopic polypectomy may offer a safer alternative to conventional methods.
    • Technical failures were linked to narrow colonic lumens, thin stalks, and precise loop placement challenges.
