Laparoscopic extracorporeal ligation of hernia defects using an epidural needle and preperitoneal hydrodissection.

PURPOSE: This article presents the extracorporeal ligation of inguinal hernia defects using an epidural needle and preperitoneal hydrodissection. PATIENTS AND METHODS: Thirteen children underwent laparoscopic extracorporeal ligation of their hernia defect using an epidural needle and preperitoneal hydrodissection. A 5-mm trocar for an operative laparoscope was placed through an infraumbilical incision, a Veress needle for forceps was inserted halfway between the umbilicus and the anterior superior iliac spine on the contralateral side of the hernia, and a 17-gauge epidural needle was inserted at the point of the internal inguinal ring. The hernia defect was closed extracorporeally by a nonabsorbable suture, which was introduced into the abdomen through the epidural needle on the lower half of the hernia defect and withdrawn on the opposite side by a wire-loop through the epidural needle going along the upper half side of the hernia defect in a series of movements. When a contralateral hernia defect is present, laparoscopic-assisted extracorporeal ligation of the contralateral hernia defect is performed during the same operation.
RESULTS: All patients were discharged uneventfully from the hospital within 24 hours postoperatively. The mean follow-up period is 6.1 months (range 2-12 mos), and no recurrence has been observed to date.
CONCLUSIONS: This article describes a unique technique of extracorporeal circuit suturing of inguinal hernia defects using a minimally invasive technique as afforded by an epidural needle.
