Abstract

This study aimed to summarize our experience in surgical treatment of mesh infection after repair of ventral hernia or defect. A retrospective analysis was conducted on clinical data of 22 patients who accepted surgical treatment of mesh infection after ventral hernia or defect repair. Included were 16 cases of infection after incisional hernia repair, 5 cases of infection after abdominal wall defect repair following abdominal wall tumor resection, and 1 case of infection with fistula caused by a parastomal hernia of an ileal neobladder repair with a prosthetic patch. All patients had received local dressing treatment for 2 to 24 months but were not healed. The affected mesh was removed successfully in all patients. Six patients had abdominal wall repair using the component separation technique; 4 patients were treated by strengthened repair with polypropylene mesh; 10 patients were repaired with human acellular dermal matrix; 1 patient received local dressing changes and vacuum sealing drain treatment without repair; and 1 patient received wound closure without strengthened repair. The postoperative hospital stay was 9-29 days (mean 16 days). After treatment, 19 patients recovered with primary wound healing and 3 patients recovered with secondary healing. All patients were followed up for 6-38 months (mean 26 months), and no ventral hernia or defect recurred except 1 case of lower abdominal bulge. Mesh infections after ventral hernia or defect repair are difficult to treat using prosthetic materials. For satisfactory results, surgery should be performed according to the specific condition of the individual.
