Purpose: Elective repair of large incisional hernias using posterior component separation with transversus abdominis release (TAR) has acceptable wound morbidity and long-term recurrence rates. The outcomes of using this reconstructive technique in the non-elective setting remains unknown. We aim to report 30-day outcomes of TAR in non-elective settings.

Methods: All patients undergoing open TAR in non-elective settings were identified within the Americas Hernia Society Quality Collaborative (AHSQC). A retrospective review was conducted and outcomes of interest were 30-day Surgical Site Infections (SSI), Surgical Site Occurrences (SSO), SSOs requiring procedural intervention (SSOPI), medical complications, and unplanned readmissions and reoperations.

Results: Fifty-nine patients met inclusion criteria. Mean BMI was 36.6 ± 8.9 kg/m2 and mean hernia width was 14.4 ± 7.2 cm. Forty (67.8%) were recurrent hernias. Pain (88%) and bowel obstruction (79.7%) were the most frequent indications for surgery. Surgical field was classified as clean in 69.5% of cases, with an 88% use of permanent synthetic mesh and fascial closure achieved in 93.2% of cases. There were 15 (25.4%) total wound events, 8 (13.6%) were SSIs. There were 8 (13.6%) SSOPIs, 6 of which were wound opening, 1 wound debridement, and 1 percutaneous drainage. At least one wound or medical complication was reported for 37% of the patients. There were no mortalities.

Conclusion: Not surprisingly, TAR in the non-elective setting is associated with increased wound morbidity requiring procedural interventions and reoperations compared to what has previously been reported for elective cases. The long-term consequences of this wound morbidity with regard to hernia recurrence are as of yet unknown.
