Abstract:
For treatment of pediatric inguinal hernia, we fabricated a device, i.e. so called "filling type pediatric hernia sac", which treats the problem from the abdominal cavity, through the abdominal and is a self-adaptive closer, using synthetic material. The device includes filling rack, self-adaptive umbrella support bar, bottom piece, outside pulling line and device fixing lines. The filling rack is composed of 2 concentric circles of 3.0 cm diameter with peripherally fixed together and can be pulled into the shapes of a ball or an olive. The supporting bar is structured of 3 pieces with 0.5 cm wide, 4.0 cm long, cross-fixed on top of the filling rack. The bottom piece is in a circular structure with a diameter of 3.0 cm, and it is connected to the filling rack bottom. Adjust positioning stay outside the fixed on the top of the device are connected at one end, and the other end free through filling the top frame connected with the bottom slice of central fixation. By using this device, we treated 37 pediatric inguinal hernia cases with 38 side-inguinal hernia successfully. The mean duration of post-operation follow-ups was 14.6 ± 5.89 months, without hernia recurrence, obvious scar and hard sections of inguinal region. This device could provide a convenient, safe and effective plugging technology for children's pediatric hernia.
