Stones washed out of the feces are usually not gallstones, but are considered to be fecal stones combined with food debris. This is because gallstones do not pass out of the body with the stool, unless they are discharged through the common bile duct into the duodenum, where they pass through the jejunum and large intestine and pass out of the body with the feces, which is very unlikely. Gallstones are located inside the gallbladder, and in the process of being discharged, they need to pass through two narrowings, the narrowing of the cystic duct and the end of the bile duct, so in general, it is very difficult for gallstones to be discharged with the bile, unless the diameter of the gallstones is very small. Stones in the feces are mostly food residues combined into fecaliths, which are not harmful to the body after they are discharged. If the patient has any discomfort, he should go to the hospital for examination in time, and should not be careless so as not to delay the treatment.
