A form of ether dramatically dissolves gallstones inside the body and may give doctors a way to avoid operating on persons with this common affliction, the New England Journal of Medicine reported. Researchers found that the ether broke down stones when squirted through a tube directly into the gallbladders of persons who otherwise would have required surgery. They cautioned that they have tested the technique on only six persons.
