Has anyone seen this Lancet Gallbladder Flush Study?

This really changes the way I though about trying gallbladder flushes. The Lancet Volume 365, Number 9468 16 April 2005 Could these be Gallstones? "We have shown that these flushing regimes for expelling gallstones are a myth, and that the claims made by some are misleading. The appearance of a letter in an establishment journal has been used to legitimise this practice for some time and the record should now be set straight."
