A Case of Gastric Huge Intramucosal Hematoma after Snare Polypectomy / 대한소화기내시경학회지

ABSTRACT

Endoscopic polypectomy is a widely used therapeutic modality for the treatment of polypoid lesions in the gastrointestinal tract. Postpolypectomy bleeding is the most common procedure-related complication. Bleeding can occur immediately after the polypectomy or be delayed from hours to up to days. The severity of bleeding ranges from slight oozing to spurting arterial bleeding that requires immediate endoscopic hemostasis. Because severe hemorrhage can be a cause of repeat endoscopy, blood transfusion, hospitalization or surgery, endoscopists must carefully observe the patient's symptoms and hemodynamic status after an endoscopic polypectomy. Here, we report a large intramucosal hematoma and subsequent huge ulcer in the stomach as a rare complication of endoscopic snare polypectomy.
