Adults often caution children that after a full meal can not be crazy, 11-year-old teenagers do not listen, after a full meal with classmates running and playing, accidentally fell, tearing the diaphragm, the stomach in the abdominal cavity “fall” into the chest cavity, almost killed for this. Steel is a native of Supervalu, Hubei Province, and his parents are working in Jiangsu. A few days ago, he was playing with his classmates at school after lunch and accidentally fell down, vomiting and severe pain at that time, which could not be relieved after resting. When Steel’s parents found out, they rushed back to Supervalu and took the child to Wuhan University People’s Hospital overnight for thoracic surgery. After observing the X-ray film, Professor Huang Jie of the department found that there was a foreign body the size of a volleyball in Steel’s chest cavity. After further iodine hydrography, Huang Jie was surprised to find that the foreign body was actually the stomach, and the crosstown stomach ran into the chest cavity, compressing the heart and lungs and causing a series of dangerous symptoms. The stomach was returned to the chest cavity and the diaphragm was torn and repaired urgently, Professor Huang Jie successfully returned the stomach from the chest cavity to its original position in the abdominal cavity, and the steel was thus turned to safety and was discharged from the hospital yesterday. How did the stomach run into the chest cavity? Professor Huang Jie explained that there is a diaphragm between the thoracic and abdominal cavities of the human body, and the diaphragm is like a wall separating the two. The esophagus passes through the hole reserved by the diaphragm, the esophageal fissure, and connects to the stomach, which is located below the diaphragm. Some children are born with a large esophageal foramen, and the stomach can easily pass up through the diaphragm, resulting in a “thoracic stomach”. But Steel’s case was even more unusual – his esophageal foramen was normal, but his violent activity after a full meal caused the diaphragm to be directly torn by up to 8 centimeters, which led to the stomach burrowing upward into the chest cavity and endangering his life. Prof. Huang Jie reminded parents that children should not be strenuously active after eating, otherwise it may lead to serious accidental injuries such as intestinal torsion, or even esophageal laceration or diaphragm tear.
