Safety of polypropylene mesh for incarcerated groin and obturator hernias: a retrospective study of 110 patients

Abstract

Purpose: The purpose of this study was to evaluate the mesh repair for an incarcerated groin hernia.

Methods: A total of 110 patients who underwent emergency surgery for incarcerated hernias were retrospectively analyzed using a multivariate analysis.

Results: The postoperative complications were associated with bowel resection, odds ratio (OR) 2.984, and 95 % confidence interval (CI) 1.273 to 6.994. The risk factors for bowel resection were femoral hernia, (OR 5.621, 95 % CI 2.243 to 14.082), and late hospitalization (24 h<), (OR 2.935, 95 % CI 1.163-7.406). The hernias were repaired with mesh in ten of the 39 (25.6 %) patients with bowel resection and sixty-four of the 71 (90.1 %) patients without bowel resection. The complication rate of the patients with bowel resection was 53.8 % and was 26.8 % in those without. The ratios of wound infection were 23.1 and 0.0 %, respectively. Wound infections were detected in two (20 %) of the ten patients who underwent bowel resection with mesh repair; however, there were no patients in whom the mesh was withdrawn due to infection.

Conclusions: No wound infections in patients without bowel resection were detected, and mesh repair could be safely performed. Mesh repair for the patients with bowel resection is not contraindicated, as long as the clean-contamination of the wound was maintained during surgery.
