A prospective randomized study of 106 patients with unilateral primary inguinal hernia who underwent "tension-free" mesh repair was carried out. Fifty-nine procedures (group A) were performed by a single experienced surgeon and 47 (group B) procedures were performed by a team of residents each with an experience level of less than ten cases. In group A the length of operation was statistically shorter; local anesthesia was more frequently used in group A, while intra-operative sedation and general anesthesia were more frequently used in group B. A subgroup of twenty patients (group C) operated on by residents with a personal experience of at least 5 tension free repairs was selected. No statistically significant difference in operation time and in anesthesia used were found between group A and group C. No significant difference was found between group A and group B in morbidity rate, mean postoperative stay, median time to return to work, and recurrence rate. Because easy, efficacy, and minimally invasive, the tension-free mesh repair remains the gold standard in the treatment of inguinal hernia.
