Decreased recurrence rate in the laparoscopic herniorraphy in children: comparison between two techniques

J Laparoendosc Adv Surg Tech A. 2009 Apr;19(2):259-62. doi: 10.1089/lap.2008.0292.


Aim: The laparoscopic herniorraphy in children is still associated to a high recurrence rate. The aim of this study was to assess whether the addition of the lateral incision of the sac to the sole suture of the inner inguinal ring could reduce the recurrence rate.

Materials and methods: A retrospective review was performed of the collected data of 248 laparoscopic inguinal hernia repairs in 224 children (175 males, 49 females) between 8 months and 11 years of age (mean age, 5 years; median, 4) in our institution from January 2004 to December 2007. The hernia was unilateral in 204 patients (133 on the right side, 71 on the left) and bilateral in 20 patients. A 5-mm umbilical camera port for a 0-degree laparoscopic optics and two operative 2- or 3-mm reusable trocars inserted in the lower right and left quadrants of the abdominal wall were utilized. In a group of 123 patients, the inner inguinal ring was closed, adopting a W-shaped suture (inguinal ring suture; IRS). In the other group of 101 patients, a lateral incision of the sac of 1-2 cm was carried out before the W-shaped suture of the inner inguinal ring (inguinal ring incision suture; IRIS).

Results: At a mean follow-up of 24 months (range, 6-36), 5 of 133 (3.76%) hernias recurred between 6 and 12 months after surgery in the IRS group. In the IRIS group, none of the patients presented with recurrence. The rate of recurrences in the two groups was compared and analyzed with the x2 test. The resulting difference was statistically significant (P < 0.05).

Conclusion: In our experience, the incision of the peritoneum lateral to the internal inguinal ring and the W-shaped suture, compared to the sole W-shaped suture, is safe and effective in preventing hernia recurrence.
