Background: Incisional hernias in kidney transplant recipients (KTRs) can be complex because of adjacent bony structures, proximity of the allograft/transplant ureter, and context of immunosuppression. We hypothesized that our novel posterior component separation with transversus abdominis muscle release (TAR) and retromuscular mesh reinforcement offers a safe and durable repair.
Methods: KTRs with incisional hernias repaired using the aforementioned technique were identified within our prospective database (2007 to 2013) and analyzed.
Results: Eleven patients were identified (median age 49 years, body mass index 32). The median hernia size was 30 cm(2) (range 88 to 1,040 cm(2)) and 8 of the 11 patients were recurrent. Intraoperative morbidity consisted of one transplant ureter injury repaired primarily over a stent. Postoperative morbidity consisted of 2 superficial surgical site infections that resolved and 1 readmission for a blood transfusion. There were no instances of mesh infection, explantation, graft loss, or graft dysfunction. With a median follow-up of 12 months (range 3 to 69), 1 (9%) lateral recurrence has been documented.
Conclusions: For complex incisional hernias in KTRs, TAR is associated with low perioperative morbidity and durable repair.
