Discussion on the effectiveness of negative-pressure therapy in tension-free herniorrhaphy for the prevention of postoperative infection

Abstract:

Objective：To discuss the clinical value of negative-pressure therapy in tension-free herniorrhaphy for the prevention of postoperative infection. Methods：A retrospective analysis was done on 1 553 cases of inguinal hernia admitted in our treatment from January 2011 to May 2016. The incisions infection rates before and after treatment were collected and compared. Results：In 1 553 cases，there were 55 cases of postoperative incision infection（3.54%），among which，30 cases were in the drainage group（1192 cases） with a incidence rate of 2.51% and 25 cases in the control group（361 cases） with a incidence rate of 6.93%. There was a correlation between the drainage and the incision infection，and the difference was statistically significant（P=0.00）. Conclusion：It can effectively drain the exudates，promote the incision union and decrease postoperative infections by using negative-pressure drainage in the oper－ations of tension-free herniorrhaphy.
