To compare and analyze the clinical efficacy and safety of three different tension-free repair for inguinal hernia.

From March 2015 to January 2018, 162 patients with inguinal hernia admitted to the general surgery department of our hospital were randomly divided into the group A, the group B and the group C. Group A was treated with Lichtenstein repair, group B with Rutkow repair, and group C with Kugel repair, with 54 patients in each group. The operation time, the postoperative time out of bed, the hospitalization time, the visual analogue score (VAS), and the postoperative complications of patients in each group were statistically analyzed.

The operation time in group A was longer than that in group B and C, while the operation time in group B was longer than that in group C, with statistical differences (P<0.05). The length of hospital stay in group A was longer than that in group C, with statistical differences (P<0.05), but there was no statistically significant difference between group A and group B (P>0.05). The time of getting out of bed in group A was longer than that in group B and C, and the time of getting out of bed in group B was lower than that in group C, with statistical differences (P<0.05). There was no significant difference in the score of VAS between the three groups 1 day after surgery (P>0.05). At 1 month and 6 months after surgery, the scores of VAS in the patients in the three groups were lower than those before, and the scores of VAS in the group B were significantly higher than those in the other two groups, with statistical differences (P<0.05). The score of VAS between the group A and the group C was similar, and the results were not statistically different (P>0.05). The foreign body susceptibility was different among the three groups, and the group B was significantly higher than the group A and C, with statistical differences (P<0.05). The rate of foreign body susceptibility was similar between the group A and C, and the results were not statistically different (P>0.05). There were no significant differences in recurrence rate, incidence of seroma, incidence of chronic pain and incidence of surgical infection among the three groups (P>0.05).

Due to the individual differences of patients, no one operation can perfectly cope with all patients. Therefore, it is necessary to make a reasonable choice of inguinal hernia repair according to the different cases, and to make the best treatment plan according to the specific conditions of patients' conditions and medical conditions.
