Story pretty familiar in medical community (especially ER). Most of us have heard of certain famous actor (will not disclose names) who ended up in emergency room with similar complaint, but that was no eel, that one entertained himself with gerbils stuffed in rubber. Then others using inflexible devices (i.e. made of glass, or other material) often end up in emergency surgery to save their lives and having part of their intestines removed to allow for healing process to take place, some end up with ostomies (contents of upper or lower bowel empties out into pouch that hangs out off ones side)... So yes! People seek adventure in many inventive ways. That eel though.... I will not comment that!
