DW: Do they a Tums for this?
There are some things that make you think, “How does that even happen?” A 33-year-old man in Hunan, China showed up at the First Affiliated Hospital of Hunan Medical University doubled over with stomach pain and a rock-hard abdomen. A CT scan solved the mystery and showed that a foot-long eel had punched through his colon and was now swimming around his abdominal cavity.
Fearing deadly infection, surgeons rushed him into laparoscopic surgery, grabbed the wriggling fish with a clamp, stitched the intestinal hole, and washed the cavity with saline to ward off peritonitis. The patient recovered well and soon went home; the hospital didn’t say what became of the eel. Staff also skipped explaining exactly how the creature got inside, but online commenters filled the gap with knowing jokes, noting such cases pop up every few years in China.
