Core Tip

Core Tip: A 31-year-old male presented with hematochezia lasting for 2 days. computed tomography scans showed extravasation, and endoscopy was used to confirm and stop bleeding from the stem of a juvenile polyp (JP). Emergency endoscopy revealed persistent bleeding from the base of the polyp, and diagnostic polypectomy and hemostasis was performed. JPs are often detected with bloody stools. However, there have been no reports of JPs with active bleeding seen on computed tomography scans as extravasation. In this rare case, an endoscopic video showed persistent bleeding, and successful endoscopic hemostasis was achieved, and captured on video.
