Laparoscopic intraperitoneal onlay mesh for pediatric incisional hernia-a case report

The incidence of incisional hernia in pediatric patients is low in comparison with that reported in adults. In the pediatric population, primary closure has generally been favored. However, synthetic or biomedical mesh offers advantages in the repair of larger defects when primary closure is difficult. The use of laparoscopic intraperitoneal onlay mesh (IPOM) in the adult population has been well documented. In the pediatric population, a few laparoscopic approaches with direct suturing have been proposed; however, there are no reports of laparoscopic repair with the use of IPOM.

The patient was a 1-year-old girl with epigastric incisional hernia after an operation to correct a complete arteriovenous septal defect. The fascial defect (size 30 × 35 mm) was large; thus, direct suturing was considered to be associated with a high risk of thoracic deformation and recurrence. Laparoscopic IPOM was performed. The fascial defect was detected precisely through the laparoscopy, and non-absorbable mesh was placed through a 12-mm trocar. Minimal incisions were required for the trocars, and extensive dissection of the abdominal wall structure was not needed. This procedure allowed for the integrity and functional status of the abdominal wall to be maintained.

Laparoscopic IPOM is a minimally invasive and cosmetically acceptable method that can be applied to the treatment of large incisional hernias in children.
