When a man in China went to the hospital for routine surgery, his doctors found something far more unusual: live worms squirming inside his abdomen.
Using a small camera inserted into the 70-year-old's abdomen — who was due to undergo surgery to remove a tumor to treat colon cancer — doctors discovered five large, brown parasitic worms in his biliary tract, the collection of organs and connecting tubes that the body uses to produce, store and secrete bile — a yellowy-green fluid that aids fat digestion.
