Abstract: 〗[Abstract]〓Objective〖WTBZ〗〓To investigate the effect and safety of Lichtenstein，Rutkow and Kugel in treatment of adult inguinal hernia.〖WTHZ〗Methods〖WTBZ〗〓The clinical data of 155 adult inguinal hernia patients were retrospectively analyzed.All of the patients were divided into Lichtenstein group（n=61），Rutkow group（n=43）and Kugel group（n=51），according to the different surgical methods.The perioperative period，postoperative complications，postoperative pain，postoperative foreign body sensation and recurrence rate between the three groups were compared.〖WTHZ〗Results〖WTBZ〗〓There was no significant difference in operation time，offbed time and hospitalization time between the three groups（P>0.05）.Postoperative urinary retention occurred in 2 cases，scrotal edema in 1 cases，incisional infection in 1 cases，and there was no significant difference in the total incidence of postoperative complications between the three groups（P>0.05）.The VAS scores of Rutkow group were significantly higher than those in Lichtenstein group and Kugel group at 1 month and 3 months after operation，and the differences were statistically significant（P<0.05）.In Rutkow group，8 cases（18.60%）had obvious foreign body sensation，which was significantly higher than that in Lichtenstein group and Kugel group，and the difference was statistically significant（P<0.05）.There was no significant difference in recurrence rate between the three groups（P>0.05）.〖WTHZ〗Conclusion〖WTBZ〗〓Lichtenstein，Rutkow and Kugel have equal effect in treatment of adult inguinal hernia.The Rutkow group have obvious postoperative pain and postoperative foreign body sensation.Lichtenstein has curative effect in treatment of adult inguinal hernia，with fewer complications，low recurrence rate，convenient operation and low cost.
