Abstract: Objective To investigate the application of ligation of pseudo hernia sac with Endoclose needle in preventing seroma after laparoscopic totally extraperitoneal direct herniorrhaphy.
Methods 135 cases of inguinal direct hernia were randomly divided into two groups according to the ratio of 1〖DK〗∶2(45 cases in control group and 90 cases in observation group) and laparoscopic totally extraperitoneal herniorrhaphy was performed.Endoclose needle was used to ligate pseudo hernia sac in observation group.All patients were followed up for 1 year.The hospitalization expenses,hospitalization time,operation time,incidence of seroma,postoperative early and chronic pain and hernia recurrence were compared.
Results All the 135 patients completed the operation successfully.The one-year total follow-up rate was 91.85%.There were no statistically significant differences in hospitalization expenses,hospitalization time,postoperative early pain and chronic pain between the two groups.The operation time of the experimental group was slightly longer than that of the blank group.The incidence of seroma and the rate of self-reported hernia area bulge of were significantly lower than those of the blank group,and the differences were statistically significant.No recurrence of hernia was found in all patients.
Conclusion Ligation of pseudo hernia sac with Endoclose needle can effectively prevent the occurrence of seroma after laparoscopic total extraperitoneal direct hernia repair.
