Colorectal foreign bodies (FB) are challenging issues for the endoscopist especially if the mostly used methods (polypectomy snare, biopsy forceps or wire-guided 40 mm dilation balloon) failed. We report a case of a 31-year-old man who was admitted in the emergency department for the impaction of a 60 cm long and large-size FB in the sigmoid colon. We failed to remove the FB using several different standard technique because of the rigidity, the smoothness and the size of the object. After all these attempts, we built up a ‘home-made’ device inserting a 0.035 inch non-hydrophilic guidewire (Metro WireGuide, Cook Medical) doubled into an 8.5 Fr stent-pusher-catheter (Cook Medical) serving as an outer sheet in order to create a noose and we finally succeeded in the endoscopic extraction of the device. We suggest this new technique as a valid option to remove large FBs from the colon and rectum when standard endoscopic methods for FB’s extraction fail.
