Additional Stem Resection for Control of Massive Bleeding After Polypectomy for a Pedunculated Colonic Polyp

Area of Science:

• Gastroenterology
• Endoscopic Surgery

Background:

• Polypectomy-associated bleeding is the most frequent complication of colorectal polypectomy.
• Identifying bleeding sources can be challenging due to narrow resection surfaces, thrombus, and hemorrhage.

Purpose of the Study:

• To present a case where additional stem resection was used to manage massive bleeding after colorectal polypectomy.

Main Methods:

• An endoloop dislodged during polypectomy of a pedunculated sigmoid colon polyp, causing massive bleeding.
• Initial attempts to identify the bleeding vessel were unsuccessful.
• Repeat polypectomy of the resection stem was performed to widen the surface and identify the bleeding vessel.

Main Results:

• The additional stem resection successfully exposed the bleeding arterial vessel.
• Complete hemostasis was achieved after identifying and addressing the arterial source.

Conclusions:

• Additional stem resection may be a novel and effective method for managing uncontrolled arterial bleeding after polypectomy for colorectal pedunculated polyps.
