there is a natural way (not painless as you can see from the support forum) to produce faeces which some people might say is Gallstones (see 1990 article about liver flush:J Clin Gastroenterol. 1990 Apr;12(2):243. ). since the diseased gallbladder does not contract properly it cannot expel gallstones, and the common bile duct is 8mm at most, so the green blobs Chaz thinks are Gallstones are faeces - PROVEN FACT!
cholecystectomy is the only way to cure gallstones. the supposed increased incidence of cancer post-cholecystectomy has been long ago disproven -as you can see Chaz does not use up-to-date references.
