Recently, the 14-year-old girl Jia Jia (a pseudonym), who lives in Hefei, suddenly had abdominal pain, vomiting, and stool, and her family sent her to the pediatric surgery department of Anhui Provincial Hospital for examination, where she was diagnosed with intestinal obstruction and treated with emergency surgery. The result of the surgery surprised the family, the original Jia Jia’s stomach, small intestine is full of hair. According to Su Yilin, deputy director of pediatric surgery at Anhui Provincial Hospital, the child’s stomach and proximal small intestine were basically occupied by hair stones. After more than an hour of surgery, the hair stones were removed. The removed stones filled a 20 cm diameter surgical basin. Jia Jia’s mother recalled that Jia Jia had hair loss problems since she was 5 years old, and she ate the hair when she lost it. She had also said Jia Jia, then she ate secretly hiding from people, in addition to hair, she also ate her nails. Dr. Su explained, like Jia Jia this situation, is due to the “hair fecal stone” caused by intestinal obstruction, clinically rare. One is that the child has a long history of partial eating habits, the body is seriously lacking in zinc, calcium and other trace elements, resulting in abnormal taste, the need to find foreign objects to stimulate the sense of taste; another case is the child’s psychological problems, belonging to the abnormal behavior, the formation of unstoppable, repeated behavior, the need for behavior correction. Parents should help their children completely “quit” “xenophagy”.
