There are several key factors as to whether a patient can excrete via feces after inadvertently ingesting a wire ball: i. The size of the wire ball. Second, whether the patient usually has constipation symptoms. Third, whether the patient ingested the wire ball in the fasting state or in the process of eating. If the patient usually has no symptoms of constipation, it means that the intestinal peristaltic function is strong. The patient eats more food after eating the wire ball, and the wire ball and food will be mixed together. In this case, the smaller size of the wire balls may be excreted by the patient’s intestines. If the patient usually has symptoms of constipation, it means that the peristaltic function of the intestine is weakened, and if the wire ball is eaten in the fasting state, the wire ball is not wrapped with food and is more irritating to the mucous membrane of the intestine, or the size of the wire ball is larger, in this case, it is difficult to excrete the wire ball, and surgical treatment is often required.
