Abstract

INTRODUCTION: Traditional anterior component separation during incisional hernia repair (IHR) is associated with a high rate of postoperative wound morbidity. Because extensive subcutaneous dissection is avoided by endoscopic anterior component separation (eACS) or open transversus abdominis release (TAR), we hypothesized that these techniques did not increase the incidence of surgical site occurrence (SSO) compared to IHR without component separation (CS).

MATERIAL AND METHOD: This was a retrospective single-center cohort study of patients undergoing open retromuscular IHR comparing patients with or without the use of CS. Retromuscular mesh repair was performed in all patients, and CS was obtained by eACS or TAR. The primary outcome was 90-day incidence of postoperative SSO. Secondary outcomes included length of stay (LOS), 90-day readmission, 90-day reoperation rate and 3-year recurrence rate.

RESULTS: A total of 321 patients underwent retromuscular repair, 168 (52.3%) of whom received either eACS or TAR. The addition of eACS or TAR was associated neither with development of SSO (odds ratio: 1.80, 95% confidence interval: 0.94-3.46, P = 0.077) nor with hernia recurrence (hazard ratio 0.77, 0.26-2.34, P = 0.648). There was no significant difference between the groups regarding the frequencies of 90-day readmission or 90-day reoperation.

CONCLUSION: eACS or TAR as adjuncts to open retromuscular IHR were not associated with increased wound morbidity or hernia recurrence.
