Treatment of inguinal hernia by lichtenstein technique: an open prospective study

Treatment of inguinal hernia is still a challenge for the surgeon. The multitude of surgical techniques attests of the difficulty of choosing the best procedure. In the surgical B department of the Charles Nicolle Hospital we have chosen the Lichtenstein technique since 2008. The aim of this study was to evaluate the immediate and long-term results of this technique and to identify the predictive factors of recurrence.

This open prospective study included all patients who underwent an elective inguinal hernia repair in the surgical B department of the Charles Nicolle Hospital between June 1st 2008 and December 31st 2009. These patients were regularly followed for at least three years. Hernia's recurrence was the primary study endpoint. Postoperative pain, wound complications, urinary complications were secondary endpoints.  An univariate and multivariate analysis were performed to identify predictive factor of hernia recurrence.

256 men and eight women were involved in this study with a sex ratio to 32. The average age was 54 years, ranging from 18 to 85 years. we identified seven cases of recurrent hernia (2,6%) with a risk of recurrence at five years equal to 4.9%, 95%CI[4,5 - 5,3].Wound complications were present in 90 patients (34%), dominated by serums seen in 12.1% of cases. The scrotal edema was found in 32 patients (12%). Eight patients kept a postoperative pain after three years of follow-up (3%). The presence of coagulation disorders in pre-operative check-up ( OR 32.25, 95% CI [3.33- 333.3], p = 0.003) and the persistence of pain after one year of intervention ( OR 16.12,95% CI [2.68 -100], p = 0.01) were two predictive factors of hernia recurrence.

The Lichtenstein technique remains the gold standard technique in the treatment of inguinal hernias by open surgery. It is a safe, simple, reproducible procedure with a low recurrence rate.
