Single-port laparoscopic percutaneous extraperitoneal closure of femoral hernia in children and adolescents: case series.

BACKGROUND

Femoral hernias are an often unexpected groin pathology during childhood. However, the pediatric surgeon has to be aware to diagnose femoral hernia and to repair this condition. This is the first report on laparoscopic percutaneous extraperitoneal closure of femoral hernia (LPEF) in children and adolescents.

METHODS

Over a 6-year period in a bi-institutional clinical study, we retrospectively identified six children and one young adult who underwent LPEF repair.

RESULTS

Femoral hernia was laparoscopically confirmed in seven patients. Ages at surgery were 3, 5, 7, 7, 8, 8.5, and 18 years, respectively. In the first case, we combined laparoscopic diagnosis with open repair. In the consecutive six cases, hernias were repaired minimally invasively with the percutaneous extraperitoneal technique described below. During a follow-up between 6 years and 6 months, no recurrence was observed.

SURGICAL TECHNIQUE: For LPEF, we percutaneously placed a peritoneal U-shape suture with integrated transfixation of the hernia sac, closed with an epifascial knot. We performed LPEF using two graspers. The peritoneum was percutaneously punctured with a venous cannula through which the suture was inserted. One grasper was inserted through the working channel of the laparoscope to invert the hernia sac into the abdominal cavity. A mini-grasping forceps inserted through the cannula retrieved the thread and completed LPEF.

CONCLUSION

We demonstrate that single-port laparoscopic percutaneous extraperitoneal closure of femoral hernia is successful and quick in children and in adolescents.
