Abstract

Abstract:

Objective

To investigate the clinical effect of low temperature plasma ablation technology in the treatment of mesh infection after abdominal wall hernia.

Methods

From January 2007 to March 2022, 56 patients with mesh infection after abdominal wall hernia surgery who were admitted to the department of the Fourth Center of the General Surgery Department of the First Medical Center of the PLA General Hospital were selected as the research objects.29 patients diagnosed as having mesh infection after abdominal wall hernia surgery that removed the mesh and debrided with electrocautery and sharp instruments from January 2007 to December 2013 were included in the control group; 27 patients diagnosed as having mesh infection after abdominal wall hernia surgery that removed the mesh and debrided with low temperature plasma ablation were included in the experimental group.The operation time and postoperative hospital stay, the incidence of grade A wound healing, the positive rate of bacterial culture results and the incidence of adverse reactions were compared between the two groups.

Results

The operation time of the experimental group and the control group were (62.2±14.2) min and (59.3±15.7) min respectively, and the difference was not statistically significant (P＞0.05).The postoperative hospital stay in the experimental group was (28.5±3.3) d significantly lower than that in the control group (37.4±2.9) d, and the difference was statistically significant (P＜0.05).The incidence of grade A wound healing in the experimental group and the control group was 100% (27/27) and 79.3% (23/29), respectively, and the difference was statistically significant (P＜0.05).There was no statistical significance in the positive rate of bacterial culture between the two groups (P＞0.05).On the 5th and 10th day after surgery, the positive rate of bacterial culture in the experimental group was significantly lower than that in the control group at corresponding time points, with statistical significance (P＜0.05).The incidence of adverse reactions in the experimental group was 100% (27/27), which was significantly lower than 27.6% (8/29) in the control group, and the difference was statistically significant (P＜0.05).

Conclusion

Low-temperature plasma radiofrequency ablation can reduce postoperative hospital stay, improve the grade of incision healing,reduce postoperative complications, and improve the bacterial culture results of postoperative wounds, and can be used as an option for infection mesh removal.
