Single-incision laparoscopic approach for linea alba hernia in children

The aim of this study is to describe the technique and to evaluate the outcome of single-incision laparoscopic (SILC) approach for linea alba hernia in children.

A 2 cm vertical umbilical incision was made and stretched horizontally. A 5-mm trocar was inserted through middle port for the telescope. Another extra-long 5-mm 30° trocar was inserted through the lateral port, 5 mm beside the middle port. The extraperitoneal fat was removed, and the defect of linea alba was repaired after hernial sac was excised. The peritoneum was reconstructed with interrupted suture.

From May 2014 to May 2015, eight children with linea alba hernia underwent SILC. Pre-operative abdominal ultrasound showed the average diameter of hernia ring was 3.2 ± 0.7 cm. Mean operation time was 32.5 min (range = 30-45 min). Oral intake was resumed during anaesthesia recovery period. All could endure pain and discharge on the post-operative 12 h. There was no post-operative wound infection. The follow-up period was 1-12 months, no recurrence and other complications occurred.

SILC approach for linea alba hernia is a safe and effective, minimally invasive new technology. The linea alba hernia could be repaired with a cosmetic outcome.
