Abstract
Many laparoscopic techniques have been developed to repair inguinal hernia in children using either an intraperitoneal or extraperitoneal approach. Percutaneous internal ring suturing (PIRS) is one of the extracorporeal suture techniques. It could be performed with comparable surgical complication or recurrence rates and excellent cosmetic results. To minimize the perioperative complications, surgical procedures of PIRS can be performed carefully with technical refinements for inguinal hernia repair in children.

Many laparoscopic techniques have been developed to repair inguinal hernia in children with improved outcomes. There are two categories of laparoscopic suture techniques according to the suturing procedures of internal inguinal ring: extracorporeal or intracorporeal suturing and knotting. Percutaneous internal ring suturing (PIRS) is one of the extracorporeal suture techniques. By extracorporeal suturing and knotting technique, the surgical procedure of inguinal hernia repair could be simple without requiring difficult laparoscopic suturing and knotting skills. Because of the easy extracorporeal suturing and knotting techniques, operative time is short. Moreover, it could be performed with comparable surgical complication or recurrence rates and excellent cosmetic results.1,2
To prevent surgical complications or recurrences, selection of the suturing material could be critical.2,3Because of the more tissues included in the loop of suture in the extracorporeal techniques rather than in the intracorporeal techniques, using tense suture material is important to make a secure suture especially in the obese children with relatively thick abdominal wall. However, too heavy suture materials could be complicated with stitch abscess or granuloma.
In spite of the easy and feasible techniques, there are a few technical limitations of the extracorporeal suturing and knotting technique in the treatment of inguinal hernia in children. One of the limitations in the application of the PIRS could be complicated hydrocele with many septations in the sac and very small communicating internal inguinal ring.4 It could be hard to managing the complicated hydrocele only by PIRS without decompressing the hydrocele. Another limitation could be the incarcerated or strangulated hernia. In the treatment of incarcerated or even strangulated inguinal hernia, if the incarcerated organs were not reducible manually, PIRS is not applicable.
Bleeding is the main complication of PIRS in the presented study group resulting 12% of complicating rate. Intraoperative vessel injury can be resulted by blind puncture of the needle with sharp tip or limited action of the needle in the narrow space. It can be worsen to uncontrollable bleeding or large hematoma by injury of the vessels, resulting poor vision of surgical field or conversion to open surgery,5 and complicated postoperatively to wound infection or recurrence. Technical adjustments as using the safe needle, one-puncture technique or dissection with saline are required to prevent the uncontrollable bleeding during the procedures.6
