A doctor who saved a child's life

I was talking to one of my schoolmates who is a doctor during our 40th anniversary of leaving our alma mater. The doctor related one incident who saved a child's life. One day one woman came with his young child in a very panic way because the child seemed to be in agony. After examining the child, the doctor wrote a letter of referral to the hospital where this woman wanted to admit the child. According to my schoolmate, the child's intested got twisted and the faeces could not pass to it. Operation was need to remedy the situation. The woman later came and thank the doctor profusely, saying that if he had brought the child two hours later, he would have to say goodbye to the child forever.
