Abstract: Objective:To compare the effects of four different repairs on inguinal hernia.Methods:One hundred cases with primary inguinal hernia of NyhusⅠⅢ were randomly divided into four groups.Group Ⅰwere treated with open properitoneal repair,group Ⅱ were treated with Lichtenstein tension-free repair,group Ⅲ were treated with transabdominal properitoneal(TAPP) repair and group Ⅳ were treated with laparoscopic totally extraperitoneal(TEP) repair.Results:The operative time of group Ⅲ and Ⅳ were longer than that of group Ⅰ and Ⅱ(P0.01).Compared with group Ⅱ,the operative time of groupⅠwas long(P0.05).Postoperative pain of group Ⅰ and Ⅱwere stronger than that of group Ⅳ within 24 hours after operation(P0.01 and P0.05).One case in group Ⅲ and one in group Ⅳ conversed to open procedure.The activity time of cases treated with laparoscopic operation were significantly shorter than that of group Ⅰ and Ⅱ(P0.01).Conclusions:The effects of TEP and TAPP are similar.Laparoscopic hernia repair is less postoperative pain and fast recovery.
