Faecal stones can usually be removed through bowel cleansing, but if they are stubborn, they need to be removed through colonoscopy. Faecal stone is mainly due to excessive intestinal content, the intestinal content in the intestinal wall attachment time is too long, resulting in obstacles to discharge, thus forming faecal stone. Generally speaking, during colon cleansing, the lubrication of the intestinal wall is increased by stimulating the movement of the intestinal wall, which ensures that the intestinal contents are discharged quickly, and a large amount of irrigation is also conducive to the rapid discharging of fecaliths. However, for the fecal stone with too strong attachment ability and too long attachment time, it is recommended to remove the stone by enteroscopy or surgical operation. In addition, in the usual diet, must pay attention to the diet with more vegetables, fruits and other foods rich in fiber, promote gastrointestinal peristalsis of food, minimize the formation of fecal stone.
