After additional laxative bowel cleansing (PEG, Oralav, B Braun, Germany) of the intestines and after ceasing of hemorrhagic signs, second capsule endoscopy (day 7 after referral to our hospital) revealed a centrally exulcerated, subepithelial tumorous lesion with luminal growth in the ileum (Figure 1).
Fixated gross section of the polypoid submucosal tumor protruding the mucosa.
