Purpose
To assess the efficacy of surgical management of chronic mesh infection (CMI) after abdominal wall hernia repair (AWHR) in single-stage approach (complete removal of infected prosthesis and simultaneous replacement with poly-4-hydroxybutyrate mesh or BAM group), comparing results with two-stage treatment (complete mesh excision and abdominal wall repair with synthetic mesh after several months or SPM group).
Methods
Retrospective comparative study of all patients who underwent surgery for CMI between January 2006 and January 2019 at a tertiary center. We compared results in terms of epidemiological data, hernia and prosthesis characteristics, surgical and postoperative variables of both two groups.
Results
Over the 13-year study period, 2791 AWHR was performed at our hospital; the overall CMI rate was 2.5%. Of 71 patients, 30 (42.2%) were in BAM group and 41 (57.8%) in SPM group. The median cumulative operative time (252 min versus 132 min) and length of stay (16.6 days versus 6.2 days) were significatively longer in SPM group compared with BAM group, due to the need of two surgical procedures. There were a higher number of postoperative complications in SPM group (p = 0.002), some of them grade III. With mean follow-up of 36.5 months (range 21–59), there were no significant differences in terms of overall hernia recurrence and mesh reinfection in both groups.
Conclusion
The use of a poly-4-hydroxybutyrate resorbable mesh in single-stage management of CMI may be a safe and better option than two-stage approach, although more studies are needed to confirm our results.
