To compare the effect of the three surgical methods(Lichtenstein operation (conventional patch), Lichtenstein operation (self-adhesive mesh), preperitoneal repair on inguinal hernia.

A total of 473 patients with inguinal hernia admitted to the hospital from March, 2018 to December, 2019 were divided into the group A (Lichtenstein operation with conventional patch, n=175), group B (Lichtenstein operation with self-adhesive mesh, n=109), and group C (Preperitoneal hernia repair operation, n=189). The perioperative period (operative time, blood loss volume, length of stays and hospitalization costs), the visual analogue scale (VAS) score at different times after operation, the General Comfort Questionnaire (GCQ) score and long-term follow-up (recurrence rate, foreign body sensation, local effusion, infection, fever and uroschesis) of three groups were compared.

The operation duration in group B were shorter than those in groups A and C (P<0.05), and there were no differences in operation duration in group A and C (P>0.05).Intraoperative blood loss volume was different among the three groups with statistical differences (P<0.01), and the group B was the least. The hospitalization cost in group B were higher than that of groups A and C (P<0.05), and there were no differences in operation cost between group A and C (P>0.05); The VAS score of group C was lower than that of groups B and A at 12 and 24 hours after surgery (P<0.05); VAS scores of the three groups decreased gradually over time (P<0.05). After the operation, the physical dimension score of the GCQ was different among the three groups with statistical differences (P<0.001), and the group C was the highest. The incidence of foreign body sensation in group C was slightly lower than that in group A and B but here was no significant difference in the incidence of foreign body sensation among the three groups (P>0.05); There were no significant differences in the incidence of complications such as recurrence rate, local effusion, fever, and 24-hour uroschesis (P>0.05).

Lichtenstein operation (conventional patch), Lichtenstein operation (Self-adhesive mesh), preperitoneal hernia repair are all effective in the treatment of inguinal hernias, and the three methods have certain safety. The three types of surgery have varying degrees of difference in perioperative conditions, postoperative pain, comfortability, and long-term efficacy. Therefore, the selection of specific surgical methods still needs to be analyzed according to the specific situation of patients.
