A boy aged 3 years and 7 months with bulging of the left inguinal area was referred to our department. He had undergone laparoscopic percutaneous extraperitoneal closure (LPEC) for the right inguinal hernia at the age of 2 years and 2 months, and no contralateral patent processus vaginalis (PPV) was detected during the first operation. The postoperative course was uneventful, and the patient was asymptomatic for 17 months. The bulging in the left groin area gradually increased in size, and ultrasonography showed left inguinal hernia involving the small intestines. The laparoscopic reoperation revealed the presence of left inguinal hernia without PPV. He was diagnosed as having de novo inguinal hernia, and underwent LPEC for the hernia. The hernial sac orifice was closed extraperitoneally by circuit double ligation around the internal inguinal ring including the processus vaginalis using an LPEC needle. His postoperative course was uneventful without recurrence and complication for 22 months. De novo inguinal hernia in children is very rare. Laparoscopic reoperation revealed that de novo inguinal hernia without PPV can be acquired in children. LPEC is very useful for the diagnosis and repair of de novo inguinal hernia in children.
