Mesh Sutured Repairs of Contaminated Incisional Hernias

Background: We sought to evaluate the results of a new mesh sutured repair technique for closure of contaminated incisional hernias.

Methods: 48 patients with contaminated hernias 5 cm wide or greater by CT scan were closed with mesh sutures. Surgical site occurrence, infections, and hernia recurrence were compared to similar patient series reported in the literature.

Results: Of the 48 patients, 20 had clean-contaminated wounds, 16 had contaminated wounds, and 12 were infected. 69% of the patients underwent an anterior perforator sparing components release for hernias that averaged 10.5 cm transversely (range 5 cm-25 cm). SSO occurred in 27% of patients while SSI was 19%. There were no fistulas or delayed suture sinuses. With a mean follow-up of almost 12 months, 3 midline hernias recurred (6%). In these same patients, three parastomal hernias repaired with mesh sutures failed out of 4 attempted for a total failure rate of 13%.

Conclusion: Mesh sutured closure represents a simplified and effective surgical strategy for contaminated midline incisional hernia repair.
